--- Comment #3 from Dr. David Kirkby <david.kirkby at onetel dot net> 2010-10-24 04:17:44 UTC --- It looks to me that the GCC header file lacks several definitions that are in the IBM header file (DEC128_EPSILON is another example). The size of the IBM header is around twice that of the one in gcc. However, it is only fprnd_t, and a few things that depend on that, which cause the compilation of the GNU Scientific library to fail. This is the failure to build the GNU Scientific library, but I believe this is a bug in GCC and not in the GNU Scientific library libtool: compile: gcc -DHAVE_CONFIG_H -I. -I.. -I.. -g -O2 -MT make_rep.lo -MD -MP -MF .deps/make_rep.Tpo -c make_rep.c -DPIC -o .libs/make_rep.o mv -f .deps/make_rep.Tpo .deps/make_rep.Plo /bin/sh ../libtool --tag=CC --mode=compile gcc -DHAVE_CONFIG_H -I. -I.. -I.. -g -O2 -MT env.lo -MD -MP -MF .deps/env.Tpo -c -o env.lo env.c libtool: compile: gcc -DHAVE_CONFIG_H -I. -I.. -I.. -g -O2 -MT env.lo -MD -MP -MF .deps/env.Tpo -c env.c -DPIC -o .libs/env.o mv -f .deps/env.Tpo .deps/env.Plo /bin/sh ../libtool --tag=CC --mode=compile gcc -DHAVE_CONFIG_H -I. -I.. -I.. -g -O2 -MT fp.lo -MD -MP -MF .deps/fp.Tpo -c -o fp.lo fp.c libtool: compile: gcc -DHAVE_CONFIG_H -I. -I.. -I.. -g -O2 -MT fp.lo -MD -MP -MF .deps/fp.Tpo -c fp.c -DPIC -o .libs/fp.o In file included from fp.c:22: fp-aix.c: In function 'gsl_ieee_set_mode': fp-aix.c:30: error: 'fprnd_t' undeclared (first use in this function) fp-aix.c:30: error: (Each undeclared identifier is reported only once fp-aix.c:30: error: for each function it appears in.) fp-aix.c:30: error: expected ';' before 'rnd' fp-aix.c:55: error: 'rnd' undeclared (first use in this function) fp-aix.c:55: error: 'FP_RND_RN' undeclared (first use in this function) fp-aix.c:59: error: 'FP_RND_RM' undeclared (first use in this function) fp-aix.c:63: error: 'FP_RND_RP' undeclared (first use in this function) fp-aix.c:67: error: 'FP_RND_RZ' undeclared (first use in this function) make[2]: *** [fp.lo] Error 1 make[2]: Leaving directory `/home/users/drkirkby/sage-4.6.alpha1/spkg/build/gsl-1.14/src/ieee-utils' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/users/drkirkby/sage-4.6.alpha1/spkg/build/gsl-1.14/src' make: *** [all] Error 2
