I can use gcc -o xx xx `pkg-config --cflags --libs gtk+-2.0 ` Now I need to do some programs with gnome .Which need gnome.h I compiled like gcc gnome1.c -o gnome1 `pkg-config --cflags --libs libgnome-2.0 libgnomeui-2.0` Which shows: Package libgnome-2.0 was not found in the pkg-config search path. Perhaps you should add the directory containing `libgnome-2.0.pc' to the PKG_CONFIG_PATH environment variable No package 'libgnome-2.0' found Package libgnomeui-2.0 was not found in the pkg-config search path. Perhaps you should add the directory containing `libgnomeui-2.0.pc' to the PKG_CONFIG_PATH environment variable No package 'libgnomeui-2.0' found gnome1.c:1:19: fatal error: gnome.h: No such file or directory compilation terminated. As i thought I use gnome why system not contain gnome.h It is easy for somebody . When i lose some file . How can i find the correct name to yum install or find source file . -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
