Problems with clicked signals defined in Glade

Platform

Hi all,
I’m building the GUI by the Glade tool.
I defined the ‘clicked’ signal and wrote the C routine in the source file as:

void on_btnNoProblema_clicked(
	__attribute__((unused)) GtkWidget *widget, 
	__attribute__((unused)) gpointer   data)
{

When I run the application I receive the following message:

(lockrecharge:7101): Gtk-WARNING **: 15:42:28.494: Could not find signal handler 'on_btnNoProblema_clicked'.  Did you compile with -rdynamic?

Since I’m using the CMake way, I’m not able to check if the ‘-rdynamic’ is defined cause I see:

[build] [  3%] Building C object CMakeFiles/lockrecharge.dir/main.c.o

I don’t understand this :thinking: I’m sure some days ago I had no problems but now I see this message.
Any idea?

Thanks!

It’s not recommended to use Glade, even with GTK3.

I’m sure CMake has some way to show you a verbose build log.

You can also annotate the callback with G_MODULE_EXPORT, e.g.

G_MODULE_EXPORT
void on_btnNoProblema_clicked(...)
{
}

Hi @ebassi ,
is there a graphical editor for the windows or you recommend to ‘write the page by code’?

Thanks

PS: I checked with ‘nm’ command and the symbol is defined.

It seems that Cambalache is a good alternative Juan Pablo Ugarte / Cambalache · GitLab

Thanks!
But I’m just trying to run it and I guess it is not possible on my current Debian version cause WebKit2:

I presume that you have Debian Stable, because I have SID and it passes meson.

If some dependencies are unavailable on your Debian install you can also try to use the Flatpak build: ar.xjuan.Cambalache
