Older xcode versions, like 3.1.4?
Hello, I want to crosscompile for PPC, which means 10.5 / Leopard. Firstly I couldn't install libxml2-devel, but that was a simple fix, the name in Ubuntu is libxml2-dev.
I'm using "method 3" since method 1 and 2 only supports 4.3 or later. The second problem was to package the SDK (xcode314_2809_developerdvd.dmg)
sudo tools/mount_xcode_image.sh xcode314_2809_developerdvd.dmg modprobe hfsplus tmp dir: /tmp/Fi9gD7pOE chmod 777 /tmp/Fi9gD7pOE /home/snigel/crosscompile/osxcross/xcode314_2809_developerdvd.dmg: cannot determine HFS partition
The error message comes from the script mount_xcode_image.sh, not from dmg2img https://github.com/tpoechtrager/osxcross/blob/master/tools/mount_xcode_image.sh
PARTITION=$(dmg2img -l $XCODEDMG | grep 'disk image (Apple_HFS ' |
awk '{printf "%d", $2}')case $PARTITION in ''|[!0-9]) echo "$XCODEDMG: cannot determine HFS partition" exit 1 ;; esac
echo "HFS partition: $PARTITION"
Running dmg2img on its own yields the following, which looks sane to me:
$dmg2img -l xcode314_2809_developerdvd.dmg dmg2img v1.6.5 (c) vu1tur ([email protected]) xcode314_2809_developerdvd.dmg --> (partition list) partition 0: Driver Descriptor Map (DDM : 0) partition 1: (Apple_Free : 1) partition 2: Apple (Apple_partition_map : 2) partition 3: Macintosh (Apple_Driver_ATAPI : 3) partition 4: (Apple_Free : 4) partition 5: Mac_OS_X (Apple_HFS : 5) partition 6: (Apple_Free : 6)
I guess the script should have picked partition 5, so I hardcoded the script to use partition 5 and continued.
sudo tools/mount_xcode_image.sh xcode314_2809_developerdvd.dmg modprobe hfsplus tmp dir: /tmp/Kb13dijhR chmod 777 /tmp/Kb13dijhR /home/snigel/crosscompile/osxcross/xcode314_2809_developerdvd.dmg: cannot determine HFS partition HFS partition: dmg2img -p 5 -i /home/snigel/crosscompile/osxcross/xcode314_2809_developerdvd.dmg -o xcode.img &>dmg2img.log mkdir -m 777 mnt cd mnt mount -o loop -t hfsplus ../xcode.img /tmp/Kb13dijhR/mnt
mounted the xcode image to: /tmp/Kb13dijhR/mnt
now run (not as root): XCODEDIR=/tmp/Kb13dijhR/mnt ./tools/gen_sdk_package.sh
once you are done with gen_sdk_package.sh, run: umount -l /tmp/Kb13dijhR/mnt && rm -rf /tmp/Kb13dijhR
Okay, that stepped went through, let's continue.
snigel@ubuntu:~/crosscompile/osxcross$ XCODEDIR=/tmp/Kb13dijhR/mnt ./tools/gen_sdk_package.sh found Xcode: /tmp/Kb13dijhR/mnt packaging MacOSX10.3.9 SDK (this may take several minutes) ... packaging MacOSX10.4.Universal SDK (this may take several minutes) ... packaging MacOSX10.5 SDK (this may take several minutes) ...

I ran into troubles trying to unmount, couldn't with or without sudo.
snigel@ubuntu:~/crosscompile/osxcross$ umount -l /tmp/Kb13dijhR/mnt && rm -rf /tmp/Kb13dijhR umount: /tmp/Kb13dijhR/mnt: umount failed: Operation not permitted

File is still there:
~/crosscompile/osxcross$ ls -al /tmp | grep Kb drwxrwxrwx 2 root root 4096 Oct 14 13:55 Kb13dijhR
Let's ignore the unmount and try to build.
UNATTENDED=1 ./build.sh no SDK found in tarballs/. please see README.md
Let's look in tarballs
ls -1 tarballs/ cctools-870-ld64-134.9_46e5f8b.tar.xz cctools-870-ld64-242_9372d4c.tar.xz xar-1.5.2.tar.gz
Okay, the unpacked pkg files are not there, let's move them.
mv MacOSX10.* tarballs/
Let's build again.
UNATTENDED=1 ./build.sh tarballs/MacOSX10.4.Universal.pkg tarballs/MacOSX10.3.9.pkg tarballs/MacOSX10.5.pkg more than one MacOSX SDK tarball found. please set SDK_VERSION environment variable for the one you want (for example: SDK_VERSION=10.x [OSX_VERSION_MIN=10.x] ./build.sh)
Let's try again
UNATTENDED=1 SDK_VERSION=10.5 ./build.sh Lots of output from compiler... testing o32-clang ... works testing o64-clang ... works testing o32-clang++ ... works testing o64-clang++ ... works Do not forget to add /home/snigel/crosscompile/osxcross/target/bin to your PATH variable. All done! Now you can use o32-clang(++) and o64-clang(++) like a normal compiler.
Time to compile gcc 4.2.1 (which is what Leopard/10.5 uses).
GCC_VERSION=4.2.1 ENABLE_FORTRAN=1 ./build_gcc.sh. Lots of compiler output... xgcc: error trying to exec '/usr/bin/libtool': execvp: No such file or directory libgcc.mk:780: recipe for target 'libgcc_s.dylib' failed make[3]: *** [libgcc_s.dylib] Error 1 make[3]: Leaving directory '/home/snigel/crosscompile/osxcross/build/gcc-4.2.1/build/gcc' Makefile:1541: recipe for target 'stmp-multilib' failed make[2]: *** [stmp-multilib] Error 2 rm gfortran.pod make[2]: Leaving directory '/home/snigel/crosscompile/osxcross/build/gcc-4.2.1/build/gcc' Makefile:4306: recipe for target 'all-gcc' failed make[1]: *** [all-gcc] Error 2 make[1]: Leaving directory '/home/snigel/crosscompile/osxcross/build/gcc-4.2.1/build' Makefile:648: recipe for target 'all' failed make: *** [all] Error 2

Okay, let's install libtool and retry.
sudo apt-get install libtool-bin
Ouch, a rerun causes it to restart from the beginning.
UNATTENDED=1 SDK_VERSION=10.5 ./build.sh Lots of compiler output, redoing everything from scratch... libtool: unrecognized option

Perhaps I'm using the wrong libtool. https://github.com/Homebrew/homebrew/issues/28442
Let's look if I have another libtool
find . -iname libtool ./build/cctools-870-ld64-242_9372d4c/cctools/misc/libtool ./build/cctools-870-ld64-242_9372d4c/cctools/libtool
Okay, how well does these handle "-dynamic" then?
./build/cctools-870-ld64-242_9372d4c/cctools/libtool -dynamic Usage: /home/snigel/crosscompile/osxcross/build/cctools-870-ld64-242_9372d4c/cctools/libtool >[OPTION]... [MODE-ARG]... Try 'libtool --help' for more information. libtool: error: unrecognised option: '-dynamic'
and
./build/cctools-870-ld64-242_9372d4c/cctools/misc/libtool -dynamic error: ./build/cctools-870-ld64-242_9372d4c/cctools/misc/libtool: no output file specified (specify with -o output) Usage: ./build/cctools-870-ld64-242_9372d4c/cctools/misc/libtool -static [-] file [...] [-filelist >listfile[,dirname]] [-arch_only arch] [-sacLT] [-no_warning_for_no_symbols] Usage: ./build/cctools-870-ld64-242_9372d4c/cctools/misc/libtool -dynamic [-] file [...] [-filelist >listfile[,dirname]] [-arch_only arch] [-o output] [-install_name name] [-compatibility_version #] >[-current_version #] [-seg1addr 0x#] [-segs_read_only_addr 0x#] [-segs_read_write_addr 0x#] >[-seg_addr_table

This one clearly states dynamic. Good. Let's remove the libtool I installed and add this to my path.
sudo apt-get remove libtool-bin PATH=/home/snigel/crosscompile/osxcross/build/cctools-870-ld64-242_9372d4c/cctools/misc/:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

And now I'm stuck.
I can't really get any further either.

I also tried to build gcc-42-5577 on Mac OS X, but unfortunately, Xcode doesn't come with a PowerPC assembler anymore.
Maybe I can make clang target PowerPC.
Just to let you know, I was able to get gcc 5.2.0 (ppc / ppc64) and clang (ppc) working. I will setup a test branch within the next few days.
It was a lot of work to get PowerPC working, but here we go!
git clone https://github.com/tpoechtrager/osxcross.git
git checkout ppc-test
SDK_VERSION=10.5 ./build.sh # build.sh will detect PowerPC support automatically
# If you end up with powerpc-* symlinks in target/bin, then everything went well.
POWERPC=1 ./build_gcc.sh # build ppc64/ppc gcc
./build_gcc.sh # build x86_64/i386 gcc
I came across a lot of issues while adding ppc support, including:
-
Recent ld64 versions do not support ppc/ppc64 anymore.
After some googling, I found a way to add back ppc/ppc64 support via https://github.com/michaelweiser/ld64.
I created a ppc branch @ cctools-port for it.
-
PPC assembler brokenness.
Fixed via https://svn.macports.org/repository/macports/trunk/dports/devel/cctools/files/PR-37520.patch.
-
Clang <= 3.5 passes '-arch powerpc' instead of '-arch ppc' to the linker.
Fixed by adding powerpc* aliases to ld64/as.
-
Clang <= 3.4 attempts to use powerc-apple-darwinX-gcc as assembler when targeting PowerPC
Fix: Do not use clang <= 3.4 when targeting PowerPC.
-
LD64 > 97.17 doesn't like the 10.4 SDK's crt1.o.
Fix 1: Do not use the 10.4 SDK when you want to target ppc. Fix 2: Rebuild the crt blobs, the sources can be found here.
ld: in section __TEXT,__text reloc 1: sectionForNum(4) section number not for any section file '...../crt1.o... is what you'd get otherwise, not a porting bug: https://stackoverflow.com/questions/5409860/unable-to-link-ppc-after-upgrading-to-xcode-4.If you want to target 10.4, use the 10.5 SDK +
export MACOSX_DEPLOYMENT_TARGET=10.4instead. -
Clang + ppc64 only works for very simple sources.
$ ./target/bin/powerpc64-apple-darwin9-clang++ ~/tmp/test.cppfatal error: error in backend: Relocation emission for MachO/PPC64 unimplemented.clang-3.7: error: clang frontend command failed with exit code 70 (use -v to see invocation)Fix: Do not use clang when targeting ppc64.
So, in conclusion... avoid the 10.4 SDK and do not use clang when targeting ppc64.
Please let me know if everything works as expected, thanks! I can't test whether the produced binaries work or not.
I had trouble producing a working binary for gcc.
git clone https://github.com/tpoechtrager/osxcross.git cd osxcross git checkout ppc-test git pull SDK_VERSION=10.5 ./build.sh cp MacOSX10.5.pkg tarballs/ GCC_VERSION=5.2.0 ENABLE_FORTRAN=1 POWERPC=1 ./build_gcc.sh snigel@ubuntu:~/osxcross$ oppc32-gcc Undefined symbols for architecture ppc: "_main", referenced from: start in crt1.10.5.o ld: symbol(s) not found for architecture ppc collect2: error: ld returned 1 exit status
Not much of an issue, have you actually tried to compile something? ;-)
Surviving build_gcc.sh usually already means a working gcc (the cross compiler is already used to compile libgcc, libstdc++, etc.).
Simply ignore the output of gcc <no src files>. Nothing to worry about.
I fixed the Undefined symbols for architecture ppc: "_main", referenced from: "issue",
you now get the expected output.

Not much of an issue, have you actually tried to compile something? ;-)
Yes, I tried to build rtorrent, but the error I got was actually not related to the compiler. But the first thing I saw was the compiler output, ran the compiler separately and thought it was broken.
Anyhow, I'm trying to find something that I can compile and test run. Tried wget, rtorrent and curl, they fail for different reasons during the configuration phase.
So for now I just tried two simple hello world in C and in C++ iBookG4:~ snigel$ ./c.out Hello World
iBookG4:~ snigel$ ./cpp.out Hello, world!
I've been thinking about trying out macports, but your documentation says that macports does not support 10.5. I am running macports 2.3.4 (latest version) on my 10.5 machine though.
It also looks like there is 10.5 content in that release http://sourceforge.net/projects/macports/files/MacPorts/2.3.4/
Tried to launch it anyway, snigel@ubuntu:~/src$ export MACOSX_DEPLOYMENT_TARGET=10.5 snigel@ubuntu:~/src$ osxcross-macports unsupported deployment target
Sure, I can hardcode to change it, but perhaps you have more insight on why it's unsupported?

I've been thinking about trying out macports, but your documentation says that macports does not support 10.5. I am running macports 2.3.4 (latest version) on my 10.5 machine though.
There are no pre-built packages for 10.5 (anymore?).
https://packages.macports.org/<pkg>
Oh, I never use prebuilt packages with macports anyway. That's why I thought I made a great case for osxcross. Get all required sources, build them on a fast machine and transfer the binaries to my slower ppc machine.
I will try the above script for test compiles, allthough, I can only test for ppc32.
I went to /home/tmp/ppc-test and then
wget https://www.openssl.org/source/openssl-1.0.2d.tar.gz
wget http://ftp.gnu.org/gnu/wget/wget-1.16.tar.gz
wget http://curl.haxx.se/download/curl-7.45.0.tar.gz
tar zxf curl-7.45.0.tar.gz
tar zxf wget-1.16.tar.gz
tar zxf openssl-1.0.2d.tar.gz
tar: A lone zero block at 52140
I tried redownloading openssl several times from the official homepage with the same result.
This built fine, so let's change arch to something I can test: ARCH=powerpc
This also built fine, but I saw something scroll by that didn't look right:

final section layout:
During the build I could also see my terminal doing a visual bell, so I guess something is being outputted that shouldn't be.
Also, this is weird, why aren't all the binaries in my 32bit build?
powerpc-gcc/bin$ ls -1
curl
curl-config
powerpc64-gcc/bin$ ls -1
c_rehash
curl
curl-config
openssl
wget
Regardless I copied the powerpc-gcc directory to the ppc machine.

Looks like OpenSSL and wget failed to build. Use set -ex to see what's causing the build failure.

Either link statically or adjust DYLD_LIBRARY_PATH.

Either link statically or adjust DYLD_LIBRARY_PATH. Embarrassing, I misinterpreted that error message. When I pointed out DYLD_LIBRARY_PATH curl started instantly. Thanks for your patience.

The error itself looks quite straight forward, we're out of memory range. But why, I don't think it's curl. So maybe something is still producing 64bit code somewhere.
If I comment out "make install" for openssl, the script stops at wget instead:

So indeed it looks like both wget and curl are failing on make install.
Need the whole output to see what's going on.
./Configure darwin-ppc-cc --prefix=$HOME/tmp/ppc-test/powerpcc-gcc
make clean
make install CC="powerpc-apple-darwin9-gcc" AR="powerpc-apple-darwin9-ar r" RANLIB="powerpc-apple-darwin9-ranlib" &>build.log
Edit: Never mind... I am getting the same error too with gcc; clang seems to work.
I will try to add "Apple GCC" support once I am done with porting the new cctools/ld64.
Edit 2: "Apple GCC" seems to work too.
However, it will take a while until I will have a build script ready.
Is this as it should be? Both powerpc-apple-darwin9-gcc and powerpc64-apple-darwin9-gcc points to the same wrapper, with 64 in its name.
readlink $(which powerpc-apple-darwin9-gcc)
powerpc64-apple-darwin9-wrapper
readlink $(which powerpc64-apple-darwin9-gcc)
powerpc64-apple-darwin9-wrapper
On the other hand, I see no "powerpc-apple-darwin9-wrapper" existing in my file tree.
Yes. My wrapper passes some flags "under the hood" to the compiler.
You can see them by setting OCDEBUG to 1.
$ OCDEBUG=1 oppc32-gcc ~/tmp/test.c
There's something wrong with gcc, not with the wrapper. I was able to compile OpenSSL with the Apple GCC and with clang.
You can now build an Apple GCC via:
Edit: It's APPLE_GCC=1 not APPLEGCC=1
POWERPC=1 APPLE_GCC=1 ./build_gcc.sh
I successfully built LLVM/Clang 3.4, OpenSSL, wget and curl with it.
Please do the same and let me know whether the resulting binaries work.
LLVM/Clang 3.4 configure flags:
CC=powerpc-apple-darwin9-gcc CXX=powerpc-apple-darwin9-g++ \
../../llvm/configure --host=powerpc-apple-darwin9 --disable-assertions --enable-optimized
Or try my binaries: http://51.254.123.149/thomas/llvm-clang-3.4-ppc32.tar.xz (sha256: 61791e0c09cb3fd271991f1d10b8f23a12c94d84a5b2377f596e890b82457f80)
Hi, I downloaded your binaries to my ppc machine. I could not see curl, wget or curl though?
Anyhow, I can launch some of the applications inside.
cd Release/bin
./clang
clang: error: no input files
./count
usage: ./count
Should I test something specific?
I don't know if you can be bothered with supporting 10.4 for ppc but your issue may be that the 10.4u SDK needs apple gcc 4.0. My Snow Leopard machine has 4.0.1 build 5494.
@snigel:
No, that's enough. Thanks!
I left curl, wget and OpenSSL out because they are easy enough to build.
I will finish PowerPC support at a later time point, most things should work already though.
@WinterMute:
I think the problem is caused by ld64, not by the compiler. LD64 > 97 seems to cause troubles. What linker version are you using on that machine?
@tpoechtrager
I have this @(#)PROGRAM:ld PROJECT:ld64-97.17 llvm version 2.9svn, from Apple Clang 1.7 (build 77)
But trying to build anything against 10.4u SDK with gcc 4.2 fails quite badly on this machine.
@tpoechtrager I tried to build the PowerPC GCC under cygwin, but I got this error:
make[2]: *** No rule to make target 'host-cygwin.o', needed by 'libbackend.a'. Stop.
Apparently host-cygwin.c and co are missing from this version of GCC.
@BSzili: Is https://github.com/gcc-mirror/gcc/blob/gcc-4_2-branch/gcc/config/i386/host-cygwin.c of any help? Copy the file(s) into build/gcc/[...] then cd into build/gcc/build_* and re-run make.
Thanks for the tip! Copying just that one file wasn't enough, but copying the rest of the cygwin-related ones solved the problem:
cygwin.asm cygwin.h cygwin1.c cygwin2.c host-cygwin.c t-cygwin x-cygwin xm-cygwin.h
Now I'm stuck again at a different place, because it can't link libgcc:

rm -rf target and re-run build.sh. I think you built the linker from the wrong branch.

I did a full rebuild, but something is still not right about the linker, because it does'nt seem to produce working executables:
... checking for pid_t... yes checking for library containing strerror... configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES.

No, I definitely didn't set MACOSX_DEPLOYMENT_TARGET. I ran these commands:
