Can't compile on ubuntu specifying x86_64-linux-gnu

[josuigoa]

Hi!

first of all, thank you for creating capy, I'm very excited about it!

I'm on Ubuntu 22.10 and I've ran the default application from zig-template in ubuntu using zig build run with no problem, very nice!

But, if I run zig build -Dtarget=x86_64-linux-gnu, I have this output:

warning: 'many-counters' is broken (disabled by default)

Is it an error of capy or is more zig thing?

thanks in advance

It's more of a Capy error. When you add -Dtarget=x86_64-linux-gnu you make Zig use a barebones Linux environment, which doesn't include the GTK+ 4 development libraries that Capy requires.

Long term, I plan to make it so Capy compiles GTK+ 4 itself using the Zig build system (so it doesn't depend on the development libraries) but the GTK build process is quite complex and requires a LOT of libraries, which means I end up having to convert a dozen of projects to use the Zig build system (which is very time-consuming).
This hasn't been high on my priority list so far, so, I haven't implemented it yet.
