Trouble compiling the examples on macOS Monterey

nerk42 opened this issue 2 years ago · 6 comments

Hi,

I'm having trouble compiling the examples on macOS Monterey v12.1, using Xcode v13.2.1, and using either gcc v11.2 or clang v13.

I see the make code is linking to X11 libraries, so perhaps you've only tested it on a *nix system other than macOS.

This is what I'm getting:

$ cd sokol_gp
$ make
gcc -o build/sample-rectangle samples/sample-rectangle.c -I. -Ithirdparty -Ishaders -D_GNU_SOURCE -DSOKOL_GLCORE33 -std=c99 -Wall -Wextra -Wshadow -Wmissing-prototypes -Wstrict-prototypes -Wno-unused-function -pthread -Og -g -lX11 -lXi -lXcursor -lGL -ldl -lm

I can confirm the library works on mac, but the makefile doesn't. I wrote my own cmake file for it here https://github.com/meshula/LabImGui/blob/main/sokol_gp.cmake but I don't know if that will help at all unless you are quite familiar with using cmake.

I get same error when trying to build though cli (same command as specified in Sokol-samples)

gcc main.c libs/sokol/sokol.m -o test-app -DSOKOL_METAL -fobjc-arc -I sokol -I libs -framework Metal -framework Cocoa -framework MetalKit -framework Quartz -framework AudioToolbox

Nvm I got that error because I had defined #define SOKOL_IMPL two times

Thanks for the tip @meshula. Not familiar with cmake but I'll try to work with it and hopefully get it to work.

Please try make platform=macos, but note that the Makefile is not part of the library, it is used just for testing the samples.

Answer 6 · 2022-02-28T17:39:51.000Z

The examples compiled fine on Linux, but can't seem to be able to run them because the OS is running as guest VM without GL capabilities.

@edubart Indeed, I experimented with the Makefile, and saw that it was defaulting to Linux as the platform. So, I made macos the default manually, but the examples are still not compiling:

$ make
gcc -o build/sample-rectangle samples/sample-rectangle.c -I. -Ithirdparty -Ishaders -DSOKOL_METAL -std=c99 -Wall -Wextra -Wshadow -Wmissing-prototypes -Wstrict-prototypes -Wno-unused-function -Og -g -lCocoa -lQuartzCore -lMetal -lMetalKit
