I build sokol-examples all ok ./fips build sapp-osx-vscode|xcode-release

But I create a project use sokol build error ./fips build osx-make-release

Angluca commented 10 months ago

Oh..... build success when I change filename to hello.m!!!

How to build success when filename is hello.c ... T_T

floooh commented 10 months ago

Yes it's because on macOS the sokol headers must be compiled as Objective-C.

You can force that with target_compile_option in the CMakeLists.txt file like this:

fips_begin_app(hello cmdline)
    fips_frameworks_osx(Cocoa QuartzCore OpenGL)
    fips_files(hello.c)
    target_compile_option(hello PRIVATE -x objective-c)
fips_end_app()

...make sure to use an uptodate fips version though, the ability to put the target_compile_option inside fips_begin/end is somewhat new (ok not that new, Dec-2022).

Angluca commented 10 months ago

I've update fips ./fips update fips But It always fips 0.0.1 version So add target_compile_option(hello PRIVATE -x objective-c) always error T_T

Well, I'm glad it compile success now

floooh commented 10 months ago

...you can also check the CMakeLists.txt file here for reference:

https://github.com/floooh/cimgui-sokol-starterkit

...this builds the sokol headers into a library, but it demonstrates how to force compiling .c files as ObjC.

Angluca commented 10 months ago

Yeah, I copy sokol.c and change cmakelists.txt build hello.c use opengl ok now I 'm lazy so add sokol.h include sokol heads, Very well :)
