Unable to compile on Arch Linux

[oitzujoey]

I am unable to compile on Arch Linux.

log0.txt

% ldd --version
ldd (GNU libc) 2.40

The code preventing it from compiling seems to be this:

code/qcommon/q_shared.h:417

#ifdef __linux__
#ifdef __GLIBC__
#if idx64
// force version for better runtime compatibility
__asm__(".symver logf,logf@GLIBC_2.2.5");
__asm__(".symver powf,powf@GLIBC_2.2.5");
__asm__(".symver expf,expf@GLIBC_2.2.5");
__asm__(".symver memcpy,memcpy@GLIBC_2.2.5");
#endif
#endif
#endif

I comment out the code above and I get this:

+1 same here. What i've done for now:

Then try to make it again

Okay, that's better.
Go to code/client/snd_mix.c:268 and erase this entire fragment:

#if idx64 && (!defined (_MSC_VER) || defined(USE_WIN32_ASM))
void S_WriteLinearBlastStereo16_SSE_x64( int*, short*, int );
#endif

Go to code/client/snd_mix.c:298 to find this fragment:

#if idx64 && (!defined (_MSC_VER) || defined (USE_WIN32_ASM))
	S_WriteLinearBlastStereo16_SSE_x64( snd_p, snd_out, snd_linear_count );
#else
	S_WriteLinearBlastStereo16();
#endif

And replace it with this:

S_WriteLinearBlastStereo16();

And now we have a successful build:

You should avoid the cmake unless someone improves it TBH. It's contributed by 3rd party, unmaintained with no support for things that have been added to makefile.

Expected build is with the makefile still.

Also commenting out those forced function versions will make it compile. Must be conflicting with newer glibc.

[Alex20129]

There is no problem with CMake itself. As far as I understand:

• The first problem (q_shared.h:417) is just some ancient hack, the meaning and essence of which is incomprehensible to me.
• The second problem (undefined reference to "S_WriteLinearBlastStereo16_SSE_x64") is because there is no such function "S_WriteLinearBlastStereo16_SSE_x64" anywhere in the entire project.

I didn't state or intend to that cmake as a whole is broken but the implementation of it here is not great and you should absolutely avoid it when the build steps in readme/build readme tells you to use makefile IMHO. The cmake files here are use at your own risk/ymmv.

The S_WriteLinearBlastStereo16_SSE_x64 does in fact exist, in hand crafted assembly files which aren't included or ran through the assembly tool with cmake files presently, in fact none of the asm optimized versions are included.

I ran it using make and it worked fine. I forgot to report that here.

[Trismegist0sq3]

I'm using Arch and I wrote a script that fetches latest version of Quake3e source and compiles using make.

There's also the aur quake3e git package
