Gio::File::create_for_path (...)

Platform
1

I wrote this example code

#include <gtkmm.h>

#define conf_file_name "data.conf"

class ConfigurationFile
{
public:

	ConfigurationFile()
	:
		conf_file (Gio::File::create_for_path (
			Glib::build_filename (Glib::get_current_dir(), conf_file_name)))
	{
	}

private:

	Glib::RefPtr<Gio::File> conf_file;
};

int main (int argc, char *argv[])
{		
	ConfigurationFile conffile;

	return 0;
}

At runtime, after compilation (with no errors), I get

** (process:9027): CRITICAL **: 22:06:24.645: Glib::ObjectBase* Glib::wrap_create_new_wrapper_for_interface(GObject*, GType): assertion 'wrap_func_table != nullptr' failed

(process:9027): GLib-GObject-CRITICAL **: 22:06:24.645: g_object_set_qdata_full: assertion 'quark > 0' failed

What I’m doing wrong ?

Hej,

I think you forgot to initialise glib in your main(). Adding Glib::init() as first line to your main() should fix this.
