compile issue with mac os 11.7.10

[xmansch]

user @tomkidd reverse cmakelist.txt form mmacosx-version-min=10.9 to mmacosx-version-min=10.7
but with this settings i have complie error:
/Users/mansch/Downloads/dhewm3/neo/sys/platform.h:242:10: fatal error: 'cstddef' file not found

i think we need for mac more complex compile logic

[DanielGibson]

Does it work better if in neo/sys/platform.h:242 you replace #include <cstddef> with #include <stddef.h>?

(That compile error is surprising anyway, because I think even C++98 had <cstddef>, so there's no reason why OSX 10.7 shouldn't have supported it)

[DanielGibson]

Try updating your xcode, maybe you have a buggy version

When i replace csrddef.h

/Users/mansch/Downloads/dhewm3/neo/sys/platform.h:242:10: fatal error: 'cstddef.h' file not found

Try updating your xcode, maybe you have a buggy version

i don't use xcode
only command lines tools - i use latest

Apple clang version 13.0.0 (clang-1300.0.29.30)
Target: x86_64-apple-darwin20.6.0

i use only 2 coomands: git pull && make -j8

[DanielGibson]

i use only 2 coomands: git pull && make -j8

you should also run cmake at some point (maybe cmake needs updating?)

When i replace csrddef.h
/Users/mansch/Downloads/dhewm3/neo/sys/platform.h:242:10: fatal error: 'cstddef.h' file not found

I wrote #include <stddef.h> not #include <cstddef.h>

clang: warning: clang: warning: include path for libstdc++ headers not found; pass '-stdlib=libc++' on the command line to use the libc++ standard library instead [-Wstdlibcxx-not-found]

Why is your clang trying to use libstdc++ for 10.7 even though the headers aren't available? Seems pretty broken (and not set like that by dhewm3's CMakeLists.txt, i.e. it must be the default from either the compiler itself or cmake)

[DanielGibson]

Have you tried creating a new build directory and running cmake in there to generate new makefiles?
Maybe this is because of a mixture of the settings cmake set initially when you first built dhewm3, when mmacosx-version-min was still set to 10.9, and others that were updated now for 10.7, and it's somehow in an inconsistent state?

i change to <stddef.h>
then i have this error:

i delete build dir, then
mkdir build
cd build
cmake ..
cd ..
make -j8
