Hi! I’m trying to prepare my Zig application for, like, CI/CD (a pair of acronyms I finally looked up the meaning of yesterday, so you know I’m out of my depth).
Currently I depend on five C/C++ libraries. Since harmonizing dependencies across platforms has proven tricky, I’d like to statically link as much as possible.
My (limited) understanding so far is that to do this in build.zig I need to find or create a .a file for each of these dependencies (not so bad), add that to my executable (exe in build.zig) with exe.addObjectFile("/path/to/libname.a") and then link the dependencies of the dependencies.
I think even that part is maybe not so bad. The one part I’m stuck on is when linking SDL on Mac, which needs to link some Objective-C code. copypasta-ing the Frameworks to link from Andrew’s SDL fork gets me pretty far, but I’m still getting a host of “undefined reference to symbol” complaints from the compiler, most of which start _objc_msgSend. Adding exe.linkSystemLibrary("objc") doesn’t appear to help one way or the other.
Any hints would be very welcome!
