Cross-compiling with musl-cross-make doesn't link to target libraries

Open tlaurion opened this issue 5 years ago • 16 comments

Hello.

Trying to bring thin-volume-provisioning inside of the Heads project.

My problem is that even if I force host and target hosts, point to where include files and libs are stored, it seems that thin-provisioning-tools picks up the build environement libraries (/lib64/ld-linux-x86-64.so.2 libdl.so.2 and libstdc++.so.6, that don't exist in target environement, which only provides libc.so, libaio.so.1 and libexpat.so.1 correctly, as defined below) and builds against build host ones.

So far I've created the following configuration files:

module/libexpat:

modules-$(CONFIG_THIN-PROVISIONING-TOOLS) += libexpat

libexpat_version := R_2_2_9
libexpat_dir := libexpat-$(libexpat_version)
libexpat_tar := libexpat-$(libexpat_version).tar.gz
libexpat_url := https://codeload.github.com/libexpat/libexpat/tar.gz/$(libexpat_version)
libexpat_hash := c341ac8c79e021cc3392a6d76e138e62d1dd287592cb455148540331756a2208

libexpat_configure := \
  cd expat && \
  ./buildconf.sh && \
  ./configure \
  $(CROSS_TOOLS) \
  --host i386-elf-linux \
  --prefix "/" \
  --libexecdir "/bin" \

libexpat_target := \
  $(MAKE_JOBS); \
	$(MAKE) -C $(build)/$(libexpat_dir)/expat \
  $(CROSS_TOOLS) \
	DESTDIR="$(INSTALL)" \
  install-strip

libexpat_libraries := \
	expat/./lib/.libs/libexpat.so.1 \
	expat/./lib/.libs/libexpat.so.1.6.11 \

libexpat_depends := $(musl_dep)

Which builds fine. strings of the libraries shows no dependency to local build host.

ldd build/libexpat-R_2_2_9/expat/lib/.libs/libexpat.so
build/libexpat-R_2_2_9/expat/lib/.libs/libexpat.so: error while loading shared libraries: /lib64/libc.so: invalid ELF header

which is good on the build host.

modules/libaio

modules-$(CONFIG_THIN-PROVISIONING-TOOLS) += libaio

libaio_version := 0.3.112
libaio_dir := libaio-$(libaio_version)
libaio_tar := libaio-$(libaio_version).tar.gz
libaio_url := https://releases.pagure.org/libaio/$(libaio_tar)
libaio_hash := ab0462f2c9d546683e5147b1ce9c195fe95d07fac5bf362f6c01637955c3b492

#CFLAGS line based on https://github.com/crossbuild/libaio/commit/59ca03a10ba7aa21c610bbe22e222c11351f1b94#diff-f57f2991a6aa25fe45d8036c51bf8b4dR5-R6
#CFLAGS+="-I$(INSTALL)/include -nostdlib -nostartfiles -Wall -I. -fPIC" \


libaio_target := \
	$(MAKE_JOBS) \
	$(CROSS_TOOLS) \
	prefix="/" \
        LDFLAGS="-L$(INSTALL)/lib" \
	DESTDIR="$(INSTALL)" \
	install \
	&& cp $(build)/$(libaio_dir)/src/libaio.so.1.0.1 $(build)/$(libaio_dir)/src/libaio.so.1 

libaio_libraries := \
	src/libaio.so.1

libaio_depends := libexpat $(musl_dep)

This builds fine. No external librairies shown with strings, and:

ldd build/libaio-0.3.112/src/libaio.so.1 
build/libaio-0.3.112/src/libaio.so.1: error while loading shared libraries: /lib64/libc.so: invalid ELF header

which is good since we are on the build host.

Now the tricky part.

thin-provisioning-tools_depends := libexpat libaio $(musl_dep)

Builds fine. But against /lib64/ld-linux-x86-64.so.2 of the build host (shown by strings) instead of libc.so under LDFLAGS. It is also linked against libdl.so.2 and libstdc++.so.6, which don't exist under LIBS. Also, ldd is successful, which is bad:

ldd build/thin-provisioning-tools-0.8.5/bin/pdata_tools 
	linux-vdso.so.1 (0x00007ffd547b0000)
	libaio.so.1 => /lib64/libaio.so.1 (0x000073e60390a000)
	libexpat.so.1 => /lib64/libexpat.so.1 (0x000073e6038dc000)
	libdl.so.2 => /lib64/libdl.so.2 (0x000073e6038d6000)
	libstdc++.so.6 => /lib64/libstdc++.so.6 (0x000073e6036dc000)
	libm.so.6 => /lib64/libm.so.6 (0x000073e603596000)
	libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x000073e60357c000)
	libc.so.6 => /lib64/libc.so.6 (0x000073e6033b4000)
	/lib64/ld-linux-x86-64.so.2 (0x000073e603935000)

The result should be the same as with libaio and libexpat above.

Any advice on what to change under modules/thin-provisioning-tools?

I'm afraid I have no experience with cross compiling so can't offer any advice. Please submit a pull request if you do get it working though.

That's a lot of information, but the things that stand out at me right away that you should check:

  1. Running glibc's ldd on a musl-linked program is meaningless. You want to run ld-musl-$(ARCH).so.1 --list, or make a symlink to that named ldd and run that ldd.
  2. i386-elf-linux is not a correct tuple for musl, and if that's what you're passing to musl-cross-make as the target, you're most likely going to get a broken toolchain. The correct tuple is i386-linux-musl.
  3. You don't seem to be showing what $(CROSS_TOOLS) is. Is that to set the CC, etc.? You shouldn't need that if --host is right.

Aside from that, rather than dumping more and more information, you need to express clearly what the basic thing you're doing/trying to do is, and for things that turn out different than what you expect, how you're measuring the unexpected outcome.

richfelker avatar Feb 18 '20 14:02 richfelker

In your logs it looks like your target is x86_64, not i386, so now I'm even more confused about your weird value of --host...

richfelker avatar Feb 18 '20 14:02 richfelker

@richfelker @GregorR

checking for g++... g++
checking whether the C++ compiler works... yes

You're using the host C++ compiler.

I know. The question is how to force it to use the target under /install, implied by:

-I$(INSTALL)/include \
        -L$(INSTALL)/lib \

Of $heads_cc, which is supposed to be passed to thin-provisioning-tools by $CROSS_TOOLS in global Heads Makefile above. I can't wrap my head around it.

tlaurion avatar Feb 18 '20 14:02 tlaurion

Get rid of all that $(CROSS_TOOLS), etc. stuff and just pass the right --host. Then configure will automatically choose the right tools. For some non-autoconf-based software (typically stuff like Busybox with build system derived from Linux kernel one) you need to pass a variable CROSS_COMPILE=x86_64-linux-musl- (note the final -!) to achieve the same thing. I assume CMake has its own way to do this too but I don't know it right off.

@jthornber :

autoconf && ./configure --host x86_64-linux-musl --prefix / 
checking build system type... x86_64-unknown-linux-gnu
checking host system type... Invalid configuration `x86_64-linux-musl': system `musl' not recognized
configure: error: /bin/sh autoconf/config.sub x86_64-linux-musl failed
make: *** [Makefile:382: /home/user/heads/build/thin-provisioning-tools-0.8.5/.configured] Error 1

Any insight?

Edit: seems like autoconf is the culprit and doesn't provide recognition of musl at all and relies on build system environment to provide ./configure options... Trying to find my way in passing it correctly. Any advice welcome.

Read the comments at the top of config.sub. They include the URL for an updated copy of config.sub that will recognize musl. But if you're running autoconf yourself to generate the configure script, I think config.sub is coming from your local version of autoconf and it probably means you have a really, really outdated version, in which case just updating it should fix the problem too.

@richfelker : config.guess, config.sub are coming from this repo, which dates all from 2008. Upgrading and testing.

@richfelker : Well all RPM based distros seem to provide the same autoconf. Any reason why you don't provide a ./configure script in the repo?

@richfelker : autoconf is based on what is provided here. This repo should provide the latest ones.

I ran into similar problem before, when I built thin-p tools for AArch64 platforms. The config.guess and config.sub really need to be updated, in order to support newer platforms and systems, including AArch64, RISC-V, musl, and so on. If you had done the test, please help to send a pull request.
