Pidgin-WebKit

compiling on 64-bit system

Asked by vishy

I am trying to compile pidgin-webkit on 64-bit fedora 13 and getting following error.

$ -> make
gcc -c webkit.c -o webkit.o -O2 -Wall -fpic -g -I/usr/local/include -I/usr/local/include/gtk-2.0 -I/usr/local/include/glib-2.0 -I/usr/local/include/pango-1.0 -I/usr/local/include/atk-1.0 -I/usr/local/lib/glib-2.0/include -I/usr/local/lib/gtk-2.0/include -I/usr/include -I/usr/include/gtk-2.0 -I/usr/include/glib-2.0 -I/usr/include/pango-1.0 -I/usr/include/atk-1.0 -I/usr/lib/glib-2.0/include -I/usr/lib/gtk-2.0/include `pkg-config --cflags gtk+-2.0 pidgin` `pkg-config --cflags webkit-1.0`

this happens when you try to do automatic type conversions (cast) from two types of different size like when trying to cast a pointer to a int.
In 32 bit architecture, sizeof(int) = sizeof(void*) = 4, but in 64 bit sizeof(void*) = 8, and a conversion to int is no longer valid. Try substitute the typename int to long wherever this warning appears.

Did anyone get this to work? Changing stuff in the code is a little over my head, but if there is source code available that will compile on a 64-bit system I would love to get it. Thanks!

Perhaps a better question to ask would be why are you even casting pointers into integers and/or vice versa?

Just wanted to say that I've just compiled the "karmic-fixes" branch of the pidgin-webkit plugin on Maverick x86_64 without any problem and it seems to be working so far! I'm really glad. Now to get the history to save in a half-inteligent format and Pidgin will be usable.

Can you help with this problem?
