“#include <gtk/gtk.h> : No such file or directory”.
This appears to be a common problem with VS Code because it’s all over the web. I’ve installed and included everything associated with building a GTK application but nothing seems to solve this.
VS Code can see the file because it suggests adding it to the include path but it still complains that the file can’t be found.
I’m also using ZMQ and it wasn’t included correctly either. All is well now. Here are my working configuration files for VS Code just in case this pops up again.
