Since libsdl2 was ported to CMake, I've experienced problems with the emerge of libsdl2. It fails to find the size_t type. Older ebuilds (such as libsdl2-2.30.1-r1) still compile correctly.

Created attachment 892622 [details] Build Log
This doesn't make sense at a glance, merely including stdio.h is failing despite it's including stddef.h for size_t before bits/types/struct_FILE.h? Needless to say, I can't reproduce with exact same USE. It would likely have something to do with the cmake migration, but I have no idea.
(my best guess would be that there's some conflicting define being set that throws off glibc/gcc's includes -- not that I know what might've triggered this)
Not tried to look at this at all yet but if we run out of ideas, it is the kind of shenanigan we had with fixincludes in the past, I think. But I doubt it's that.
Could you tar+compress the /dev/shm/portage/media-libs/libsdl2-2.30.3/work/SDL2-2.30.3_build-abi_x86_32.x86 directory and attach it here? The generated includes may or may not have some hints.
So I extracted the compile command that was failing and tried it with and without different compile options. I was able to narrow down the problem to this compile flag: -isystem/usr/include Not sure what in the build system is introducing that, but removing it solves the issue.
My own log has that option as well but it's not causing issues on this end.
it is something that SDL is doing in CMakeLists.txt and wasn't in with autoconf though: if(USE_GCC OR USE_CLANG) string(REGEX REPLACE "(^| )-I" "\\1 -isystem" EXTRA_CFLAGS "${EXTRA_CFLAGS}") endif() Unsure why.
So I tried commenting those three lines out in the CMakelists.txt file (lines 3060 to 3062): #if(USE_GCC OR USE_CLANG) # string(REGEX REPLACE "(^| )-I" "\\1 -isystem" EXTRA_CFLAGS "${EXTRA_CFLAGS}") #endif() And ninja now runs to completion without error.
Created attachment 892645 [details, diff] Delete CMake Regex So I applied this patch that deletes those three lines -- and I can run ebuild compile successfully. This is probably not the -right- solution. But it does seem to fix my issue for now.
Created attachment 892646 [details] SDL2-2.30.3_build-abi_x86_32.x86 folder from the broken build As requested, here's a tarball of the work/SDL2-2.30.3_build-abi_x86_32.x86 folder.
(In reply to Robert Marmorstein from comment #12) > Created attachment 892646 [details] > SDL2-2.30.3_build-abi_x86_32.x86 folder from the broken build Looks normal at a glance, and unfortunately still no idea why -isystem is making a difference.
Looking at the manpages and some online comments, it looks like the use of -isystem is to prevent some potential warning messages. So perhaps just deleting these three lines is the right patch after all?
-isystem can cause all sorts of problems, e.g. https://gcc.gnu.org/PR70129. We should propose removing it upstream. It doesn't even work reliably for avoiding warnings. *still* quite curious as to why it only affects you though
I'm not sure what could make mine different (other than age -- it's been running Gentoo on it for nearly 20 years now -- since at least 2006 and probably a bit longer). I use a pretty standard toolchain, all my packages are up-to-date, I don't use any overlays (anymore), and I'm using OpenRC instead of SystemD. Maybe it's my CFLAGS? CHOST="x86_64-pc-linux-gnu" CFLAGS="-march=native -Os -pipe"
Or my feature flags? FEATURES="sandbox collision-protect distlocks multilib-strict news clean-logs -noinfo -noman -nostrip splitdebug parallel-fetch parallel-install userfetch userpriv usersync -ccache fixlafiles" CPU_FLAGS_X86="mmx mmxext sse sse2 sse3"
(Also, just to be clear, it's not a suggestion you're doing anything wrong; just very curious as to what makes your system different.)

This might be it, then (in a kind of generic way). Sometimes we get strange bug reports from people on quite old installs (even if it's been migrated to a newer machine, ofc) because there's some old orphaned file somewhere. If you have the time and inclination, it might be interesting to see a list of orphaned files on your system in /usr, e.g. `find /usr | xargs qfile -o` (unfortunately qfile doesn't support recursion). Also wondering if there's any junk in /usr/local?
Well, that shares lots of old kernel config files, a few things from Qt3, a lot of orphaned man pages, two games that probably should have installed under /usr/local, some old awstats stuff . . . let me narrow this down a bit and I'll share. /usr/local has an old copy of FICS (Free Internet Chess Server) I used to run, a custom version of kdenlive from a bugfix I wrote many years ago, and some ruby/sass stuff. /usr/local/lib is empty except for the ruby gems. And /usr/local/lib64 is empty except for some libraries I wrote for my dissertation. I don't think any of that would interfere with libsdl2, but I can clean it out and see.
