The LLVM ports do not include various standard C/C99 headers because of this patch: <https://cgit.freebsd.org/ports/tree/devel/llvm17/files/patch-clang_lib_Headers_CMakeLists.txt> My specific problem is that this prevents Wine from using LLVM/clang from ports as a PE cross-compiler. In this case Wine uses clang in the 'x86_64-windows' mode, configure does a check in this mode and tries to build a sample file which includes <stddef.h>, and this fails. LLVM/clang packages on other OSes (Gentoo Linux, macOS Homebrew) do include these files. And more generally, anyone trying to use ports LLVM/clang to target a freestanding/bare-metal environment would not be able to use any of these standard header files. E.g. for a very simple test.c: #include <stdint.h> uint64_t hi(void) { return 1; } and build with: $ /usr/local/bin/clang --target=arm-none-eabi -nostdlib -o test.o test.c
We either need to patch FreeBSD's include files so that it can build with the llvm ones installed or patch the llvm ones to honor FreeBSD's guard macros. I'm not sure which is the best approach, but until that's resolved we're stuck in this situation.

(In reply to commit-hook from comment #3) So, here's a report of broader testing: this (and previous) commit broke emulators/wine packaging unfortunately, please see #279677 for details.
I have an update for emulators/wine-devel in the works where these changes actually are *required* to move to Wine 9.9 or later. And if things work out as expected plan on pushing back these changes to emulators/wine as well. (Timing is not too critical since the packaging issues with emulators/wine only happen when one changes LLVM_DEFAULT to 17 or 18.) Brooks, are you planning to push back your changes to devel/llvm16?

When trying to build with LLVM 15, which is the current default in the Ports Collection we have been using for a while, we now get the following error: configure: error: Suitable PE cross-compiler not found, PE files won't be built. This is an error since --with-mingw was requested. ===> Script "configure" failed unexpectedly. This is not actually a regression from Wine 9.8 to 9.9; rather Wine now diagnoses this (again) instead of simply proceeding. Luckily our devel/llvm18 and devel/llvm17 ports just recently addressed the situation with commits c56fde6514 on May 28 and b21e6b4de1 on June 12, respectively. Accordingly force the use of at least devel/llvm17. [2] This brings a huge number of changes in terms of pkg-plist. (The emulators/wine port will need similar changes or it'll break with builds of LLVM that contain these changes already in the two ports above.

It significantly changes what Wine builds, though. For emulators/wine-devel we moved to the new world order already; for emulators/wine remain a bit more conservative and stay with status quo ante by firmly using LLVM 15. For most users this won't make any difference since so far we have been using LLVM_DEFAULT which currently stands at ... 15. On the way use the new USES=llvm facility instead of doing things more manually. PR: 279677, 274542 [1] emulators/wine/Makefile | 15 +++++---------- 1 file changed, 5 insertions(+), 10 deletions(-)
Thanks all, this seems fixed now. devel/llvm now includes all the header files, and can be used as a PE cross-compiler by Wine.
