Incompatible with Wine 10.0-1/gcc 14/Arch linux + workaround

[Anakiev2]

tldr - Enabling/Disabling Gallium nine doesn't work on Arch Linux. I've managed to fix it by replacing one string.

Long story - ninewinecfg cannot enable or disable Gallium nine on Arch Linux with either cli or gui. Running wine ninewinecfg -e returns 1. Running wine ninewinecfg -d returns 0 but it's not disabled. With the gui the checkbox Enable Gallium Nine... cannot be checked (no matter how many times I click). There is no output in the terminal window indicating what's wrong. It's the same with the latest version from github (wine-nine 0.11-devel).

I've managed to fix the problem by replacing this line:

wine-nine-standalone/ninewinecfg/main.c

Line 260 in 909f059

return !strcmp(buf + ret - strlen(fn_nine_dll), fn_nine_dll);

with return !strcmp(buf + ret - strlen(fn_nine_dll), "9-nine.dll.so");.

I've found the "correct" string by printing some variables to stdout:

buf="/usr/lib32/wine/i386-unix/d3d9-nine.dll.so"
buf+ ret=""
buf + ret - strlen(fn_nine_dll)="9-nine.dll.so"
fn_nine_dll="d3d9-nine.dll"

After recompiling the checkbox works. Both the gui and the cli (with -e/-d) can enable/disable successfully.

Tested on:

wine 10.0-1
wine 9.22-1
wine-staging 9.22-1
wine-nine 0.10-1
linux 6.12.10.arch1-1
gcc 14.2.1+r134+gab884fffe3fc-2

I've done some more debugging and the presents of .so in the path creates the problem. I don't know if this is Arch Linux specific issue. This is my updated "fix" to add a local variable in is_nine_symlink() with the correct filename:

It works perfectly fine.
