I guess the error is that /usr/include/gnu/stubs-32.h doesn't exist on your box, which is easily solvable by sudo yum install /usr/include/gnu/stubs-32.h (which is the same as sudo yum install glibc-devel.i686 ). You want also 32-bit libgcc if you don't have it installed, so sudo yum install glibc-devel.i686 libgcc.i686 Jakub -- 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
