Alien::SDL fails to build from source with GCC 15 and Perl 5.42 #313
Description
Alien::SDL (dependency of kthakore/frozen-bubble) fails to build in openSUSE 16.0 under Windows Subsystem for Linux due to GCC 15 and Clang 16 not allowing empty parameter prototypes for functions which actually take arguments. Also, SDLPango_CopyFTBitmapToSurface() is used before it is defined.
After fixing all of the below prototype problems, the Perl module builds, but I haven't tested that it works.
I found this bug because my brother tried to install frozen-bubble on his NixOS-unstable computer and he got a compile error. I'm running Windows 10 and I get the same error as him under openSUSE-WSL and also in a NixOS-25.11 VirtualBox VM using an overlay.
Builds on:
• NixOS-25.11
Doesn't build on:
• openSUSE 16.0
• NixOS-unstable
• NixOS-25.11 VM with overlay to grab latest Perl and GCC
Steps to reproduce:
• try to run perl Build.PL;perl Build in Alien-SDL checkout with GCC 15.
• Or, cpan install Alien::SDL with GCC 15.
Reproducibility:
Always fails to build with GCC 15; used to work on older GCC as it was less strict.
Expected vs Actual:
Expected it to build successfully with no errors.
Actual: 4 different source files give an error on GCC 15.
My computer's WSL software:
Perl version: 5.42.1 (installed with perlbrew)
GCC version: 15.2.0
openSUSE version: 16.0
Hardware: MSI GS63 Stealth 8RE
Windows Terminal version: 1.23.20211.0
Windows Subsystem for Linux version:
WSL version: 2.6.3.0
Kernel version: 6.6.87.2-1
WSLg version: 1.0.71
MSRDC version: 1.2.6353
Direct3D version: 1.611.1-81528511
DXCore version: 10.0.26100.1-240331-1435.ge-release
Windows version: 10.0.19045.7058
Wrong prototypes:
close_display in Xinerama.c
• fixed in libsdl-org/SDL-1.2@e738cff
XiGMiscCloseDisplay in xme.c (also fixed in above commit)
Mix_InitFluidSynth/Mix_QuitFluidSynth
• reported in libsdl-org/SDL_mixer#287
• fixed in libsdl-org/SDL_mixer@05b12a3
SDLPango_CopyFTBitmapToSurface needs a prototype, used before function definition seen.
• SDL_Pango from sourceforge seems to be inactive
• SDL2 version at markuskimius/SDL2_Pango
