Hello, Just as a follow-up, I'm trying to install Racket on a lab's computer running "Red Hat Enterprise Linux 5.7", gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-51).
Racket 5.1.3 unix source still shouts the same error message when trying to compile without workarounds... At least now I know what to do :) []'s Rodolfo Carvalho On Fri, Aug 12, 2011 at 19:19, Matthew Flatt <mfl...@cs.utah.edu> wrote: > The problem seems to be that __sync_bool_compare_and_swap() is > available only when the compiler knows that its generating code for > i486 or up, and it's not available when compiling for i386. > > The Racket headers files try to use C pre-processor tests to decide > whether to use __sync_bool_compare_and_swap(), but a `configure' test > will be more reliable.
