hi

I've finally managed to get xorg-server compiled and running.
I've also managed to get llvm and mesa compiled.
When I tried to run simple 3d test program,
I got "Error: GLX version >= 1.3 is required"
I've checked /var/log/Xorg.log, and got:
Failed to load /usr/lib/xorg/modules/extensions/libglx.so: Error
relocating /usr/lib/libGL.so.1: _ITM_dereg
isterTMCloneTable: initial-exec TLS resolves to dynamic definition in
/usr/lib/libGL.so.1

I've searched the web and found this thread:
https://bugs.freedesktop.org/show_bug.cgi?id=35268

It seems musl was fixed 4 years ago.
I've checked musl-1.2.2 source code, indeed, the fix seems to be
there. (tlsdesc.s)

So, I recompiled mesa with patches from the thread.
but I still get the same error message.

I also tried this simple code:
#include <dlfcn.h>
#include <stdio.h>
int main()
{
    void *handle = dlopen("/usr/lib/libglapi.so", RTLD_LOCAL | RTLD_NOW);
    if (!handle) {
        printf("dlopen failed with message '%s'\n", dlerror());
    }
}

dlopen failed with message 'Error relocating /usr/lib/libglapi.so:
_glapi_tls_Context: initial-exec TLS resolves to dynamic definition in
/usr/lib/libglapi.so'

Most of what was discussed in the thread was way over my head.
I could use some help. Thanks.

You need to disable TLS in Mesa.  Try something like this patch:

https://cgit.adelielinux.org/packages/tree/user/mesa/no-tls.patch

Hope this helps you.

Best,

It does! Thanks a lot. In my case, I only need to change
"--enable-glx-tlsd" to "--disable-glx-tls" during autogen.sh
I also did some benchmarks:
# glmark2 Score: 2109 # glibc
# glmark2 Score: 1993 # musl
And some light tracing shader code test:
# glibc 29 seconds vs musl 30 seconds.
It holds up very well. I'm very happy. Thanks.

BTW, I noticed "https://cgit.adelielinux.org/packages/tree/user/" only
has mednafen.
desmume, mupen64plus, and mame, all compiled without patches :)

The short answer is that I have submitted a fix which is included in 
Mesa 22. It seems that Mesa 22 has been delayed several times; -rc2 is 
out, but I don't know when the final will be released.

In general, I would suggest using a full Linux distribution instead of 
compiling packages individually. If for some reason you insist on 
compiling packages individually, the various musl-based Linux 
distributions are still a good reference for which patches and 
other adjustments are required for musl compatibility.

Cheers,
Alex.

Proper solution is to use current mesa, this has already been fixed 
upstream so the downstream patching is no longer required.
