Cannot build the latest UASM on macOS

[anta40]

I'm on macOS Big Sur, and have some C/C++ compilers installed:

• gcc (a.ka clang 12) via Apple Command Line Tools
• gcc-11 and clang 12 via Homebrew

After pulling the latest code from git, none of them can build UASM:

make -f ClangOSX64.mak 
gcc -D __UNIX__ -c -IH -D __UNIX__ -DNDEBUG -O2 -ansi -funsigned-char -fwritable-strings -o GccUnixR/dbgcv.o dbgcv.c
In file included from dbgcv.c:13:

                ^
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/alloca.h:39:9: note: previous definition is here

         ^
dbgcv.c:20:10: fatal error: 'direct.h' file not found
#include <direct.h>
         ^~~~~~~~~~

So I did some adjustments on dbgcv.c:

• Replaced <direct.h> will <unistd.h>
• Added #define _MAX_PATH 4096
• Replaced _getcwd with getcwd

So far, the error count is reduced into 4. I still have no idea how to solve the first 2:

dbgcv.c:1572:16: error: use of undeclared identifier '_pgmptr'
                len = strlen(_pgmptr) + 1;
                             ^
dbgcv.c:1573:17: error: use of undeclared identifier '_pgmptr'
                s = strcpy(s, _pgmptr) + len;

Seems like _pgmptr is Windows-specific.

And the last 2 are casting errors:

dbgcv.c:1582:41: error: 'char *' and 'uint_8 *' (aka 'unsigned char *') are not pointers to compatible types
                EnvBlock->reclen = (unsigned short)(s - cv.ps - 2);

                      ^ ~

You may want to have a look at the changes in https://github.com/Terraspace/UASM/pull/146 and test those on your system.

Sorry for the late very reply. As I usual, pulled the latest code git, and applied the changes mentioned in #146. Now I'm facing different error messages:

Do you want to try the steps from this Dockerfile I made? https://github.com/justdan96/7zip_static/blob/main/Dockerfile#L13

I followed your steps On MacOS, seems like there's no built-in strupr(), so I took this simple implementation and put that in assemble.c

Now 1 error left:

assemble.c:1191:3: error: implicit declaration of function 'AddSimdTypes' [-Werror,-Wimplicit-function-declaration] AddSimdTypes();

I've added most of the fixes from the open pull requests plus a few extra ones to fix building on Linux. Maybe that also helps you to build on Mac: https://github.com/darealshinji/UASM

You should also disable all "-Werror" flags.

[teoberi]

Try some pull requests with your changes, maybe something will move with compiling in Linux.

All the important fixes are already present as PRs, the rest is just silencing compiler warnings.

[teoberi]

Yes I follow the development of UASM, many want to help but nothing concrete is seen.

@anta40 Strange, I cannot confirm this on Ubuntu using gcc version 9.3.0. Make uses "cc" as compiler, are you sure that this is "gcc" on your system? Are you using the latest revision of the "gcc-fixes" branch? It says the symbol "MODULEARCH" was previously defined in main.o, but in main.c there's only one instance of this symbol and it's commented out, so that doesn't make sense (the other symbols don't even appear in main.c).

Can you try to delete the "Release" directory and run it again with "CC=gcc make -f Makefile"?

When using v2.55, sed -i -e 's/-ansi/-Wno-error=implicit-function-declaration/' UASM-2.55/ClangOSX64.mak worked.

I published https://github.com/cielavenir/homebrew-ciel/blob/master/uasm.rb .

sed -i -e 's/-ansi/-Wno-error=implicit-function-declaration/' UASM-2.55/ClangOSX64.mak

I just tried this using UASM 2.55 (not modified at all), and uasm built succesfully. Interestingly, it doesn't work with the very latest version on git, though.
