[SOLVED] Error when creating object file
opened this issue · comments
Here's the log for default command that links executable, it will give the following error:
$ w32-clang main.c -o main.exe

clang: error: assembler (via gcc) command failed with exit code 1 (use -v to see invocation)If I enable mingw linker:
w32-clang main.c -o main.exe -wc-use-mingw-linkerAll is fine! Executable is created. Now let's try to create object file:
$ w32-clang -c main.c -o main.obj

clang: error: assembler (via gcc) command failed with exit code 1 (use -v to see invocation)Any ideas?
Ok, I'm not sure how right this will be, but it fixes the issue:

Wrong assembler.
Please post your clang version + the output of w32-clang test.c -wc-verbose -v.
-wc-use-mingw-linker explicitly invokes gcc instead of clang, thus, it should only be used for linking with incompatible flags.
I just downloaded and built MXE and everything works flawlessly for me.

I am using clang 3.5.1, you are probably using 3.4 or 3.3 since the integrated assembler is enabled by default on later versions.
You may be able to get rid of that error by either:
- upgrading clang to 3.5.1
or
- by setting
export COMPILER_PATH=/path/to/mxe/usr/bin/(where i686-w64-mingw32.shared-as is located)
or
- by symlinking all mxe mingw tools (mxe/usr/bin/*) into the clang binary directory
Ah, yes! You're right, I've used Clang 3.4, it's the default version of Clang on Ubuntu 14.04. I had to enable LLVM's repository to install the latest one and symlink clang-3.5 and clang++-3.5 to clang and clang++ respectively.
Then it throwed these errors:
$ w32-clang main.c

clang: error: linker (via gcc) command failed with exit code 1 (use -v to see invocation)I exported COMPILER_PATH variable with export COMPILER_PATH=/opt/mxe/usr/bin/ and it started to compile executables and object files just fine!
Thank you, Tom!
Can we include a note about Clang 3.5 and COMPILER_PATH global variable in readme?
Ah, yes! You're right, I've used Clang 3.4, it's the default version of Clang on Ubuntu 14.04. I had to > enable LLVM's repository to install the latest one and symlink clang-3.5 and clang++-3.5 to clang and clang++ respectively.
I would avoid that repository, that repository is known to contain broken compilers...
Also ensure it's 3.5.1 and not 3.5.0, 3.5.0 has an annoying bug: http://llvm.org/bugs/show_bug.cgi?id=20746.
You may simply go with: http://llvm.org/releases/3.5.1/clang+llvm-3.5.1-x86_64-linux-gnu.tar.xz.

Yes of course, feel free to do a pull request (for #15 too).
