I'm having a whack at upgrading rexxGTK to GTK4. I'm working in Ubuntu
22.04 which has gtk4 installed. In the make file flag are set
specifying packages(?) libraries(?) to be used:
GRXLFLAGS = `pkg-config --libs gtk+-2.0 gdk-2.0 glib-2.0 gthread-2.0`
GRXCFLAGS = `pkg-config --cflags gtk+-2.0 gdk-2.0 glib-2.0 gthread-2.0`
After easter-egging around, I determined that
GRXLFLAGS = `pkg-config --libs gtk4`
GRXCFLAGS = `pkg-config --cflags gtk4`
would get the compiler to run and generate complaints like:
rexxgtk.h:78:20: error: ‘GdkEventKey’ has not been declared
78 | GdkEventKey *event,
| ^~~~~~~~~~~
rexxgtk.h:81:20: error: ‘GdkEventButton’ has not been declared
81 | GdkEventButton *event,
presumably because I hadn't specified the current equivalent of gdk-x.x
in cflags.
My question may be more related to linux than oorexx, but ... how can I
determine the correct value to specify for --cflags and --libs. How do I
determine the release/package name for GDK, GLIB and GTHREAD.
