Zig build failed

General

Hi All,

I got the following error response. I looks like it’s failing because the build file can’t find the addPassthruArgs function or value. The only thing I can think if is that it is a version issue. I am using Zig version 0.16.0. the addPassthruArgs does not exist in the Run.zig file :

❯ ./your_program.sh
build.zig:31:12: error: no field or member function named ‘addPassthruArgs’ in ‘Build.Step.Run’
run_cmd.addPassthruArgs();
~^~~~~~~~~~

Thanks in advance for any help!

OK I was able to look at the code on a few sites and I had to modify the build file in order to make it work. Since I am on Zig version 0.16.0 and this seems to on 0.17.0. The subtle diffrence was that function. I had to also add the import builtin so I could detect the version. This is the following change I added:

const builtin = @importimport(“builtin”); // added as line #2

I also added the following to replace line 33:
if (comptime builtin.zig_version.minor >= 17) {
run_cmd.addPassthruArgs();
} else {
if (b.args) |args| run_cmd.addArgs(args);
}

This allowed for the app to run and then I got the follwing error. I think this part is expected and I need to add the needed code but just placing it here in case I am wrong:
