 |

Hello,
After switching to gcc14, https://github.com/flyinghead/flycast compilation fails (no issue if I use gcc12)
| Code: | x86_64-pc-linux-gnu-gcc -DTARGET_LINUX_x64 -DHOST_CPU=0x20000004 -DPICO_SUPPORT_UDP -DPICO_SUPPORT_DHCPD -fopenmp -D__LIBRETRO__ -DHAVE_GLSYM_PRIVATE -DNO_VERIFY -fno-builtin-sqrtf -DENABLE_MODEM -DMINIUPNP_STATICLIB -DNDEBUG -DHAVE_GL3 -funroll-loops -DCORE -DHAVE_TEXUPSCALE -DHAVE_OPENGL -DHAVE_VULKAN -DHAVE_STDINT_H -DHAVE_STDLIB_H -DHAVE_SYS_PARAM_H -D_7ZIP_ST -DUSE_FLAC -DUSE_LZMA -O3 -c -fno-strict-aliasing -fomit-frame-pointer -fPIC -I./core/libretro -I./core/ -I./core/deps -I./core/deps/libchdr/include -I./core/deps/lzma/C -I./core/libretro-common/include -I./core/deps/vixl -I./core/deps/stb -I./core/deps/picotcp/include -I./core/deps/picotcp/modules -I./core/deps/miniupnpc -I./core/deps/khronos -I./core/deps/glslang -I./core/deps/flac/include -DTARGET_LINUX_x64 -DHOST_CPU=0x20000004 -DPICO_SUPPORT_UDP -DPICO_SUPPORT_DHCPD -fopenmp -D__LIBRETRO__ -DHAVE_GLSYM_PRIVATE -DNO_VERIFY -fno-builtin-sqrtf -DENABLE_MODEM -DMINIUPNP_STATICLIB -DNDEBUG -DHAVE_GL3 -funroll-loops -DCORE -DHAVE_TEXUPSCALE -DHAVE_OPENGL -DHAVE_VULKAN -DHAVE_STDINT_H -DHAVE_STDLIB_H -DHAVE_SYS_PARAM_H -D_7ZIP_ST -DUSE_FLAC -DUSE_LZMA -O3 -c -fno-strict-aliasing -fomit-frame-pointer -fPIC core/deps/libzip/mkstemp.c -o core/deps/libzip/mkstemp.o
core/deps/libzip/mkstemp.c: In function ‘_zip_mkstemp’:
core/deps/libzip/mkstemp.c:70:15: error: implicit declaration of function ‘getpid’ [-Wimplicit-function-declaration]
70 | pid = getpid();
| ^~~~~~
make: *** [Makefile:1183: core/deps/libzip/mkstemp.o] Error 1
make: *** Waiting for unfinished jobs....
* ERROR: games-emulation/libretro-flycast-9999::localrepo failed (compile phase):
* emake failed |
This is a live ebuild. libzip version used by the project is @1.10.1.
Any idea ?
Thanks.

That sounds odd considering this file does not exist in the repo, it was removed when it bumped to 1.7 all the way back in January 2021 (https://github.com/flyinghead/flycast/commit/16dec49e08838). So you probably aren't using 1.10.1 right now.
Is your live ebuild's checkout updating properly? Or is it using a different repo than the one you linked, like a libretro-specific fork?
Either way, that error would be an indicator that the file is missing a #include <unistd.h>, which exists but it guarded it behind a __APPLE__ for some reason: | Code: | #if defined(__APPLE__)
#include <unistd.h>
#endif |
(so, just need to remove the if/endif lines, not to say there may not be more problems with that old version -- and gcc14 has new defaults to error out on these blatant code issues so people start fixing them rather than hope they work by accident) |

Sorry Ionen, indeed I linked the wrong url and got confused. The libzip included in the fork is quite old indeed.
I am using indeed a libretro fork : https://github.com/libretro/flycast
| Code: | | LIBRETRO_REPO_NAME="libretro/flycast" |
I'll have a look at your suggestion.
There is this pull request to update some deps : https://github.com/libretro/flycast/pull/952
but it's been almost 4 years already... And libzip is not even in the list.
Otherwise, is it possible to checkout a different commit for libzip submodule while using libretro eclass with LIBRETRO_REPO_NAME="libretro/flycast" ? |

| libzip is not a submodule in either repo, it's hard-included as part of the repo -- newer versions could potentially be incompatible with the rest of the code that hasn't been updated in the libretro fork (likewise for other bundled deps). |

You're right 
Well, I opened a bug : https://github.com/libretro/flycast/issues/1194
I think that's better this way so it can benefit others too. I have 4 other libretro cores build failure with gcc14 to report too  Not so bad... I'll keep gcc12 around meanwhile. |
