In CMake, there’s a function check_cxx_symbol_exists that check if a function or variable exists in a file, I want to replicate that in build.zig, is there a function for that for C/C++ files?
zig files being struct, you might be able to leverage @typeInfo for that purpose.
sorry, I mean for checking the symbols in C/C++ files, not Zig files.
I’m pretty sure the answer is no. You’ll probably have to leverage some other tool to achieve this.
I think so also, it seems like I have to look into Zig’s internal to know what flag value to set correctly when compiling C/C++ libraries.
A hacky way I can think of is using b.addTranslateC and then inspecting the resultant output_file somehow. Probably not the best way, though.
It doesn’t work since addTranslateC runs after the build script is built and for addConfigHeader, the macro values have to be defined before that.
