--- Comment #6 from Jonathan Wakely <redi at gcc dot gnu.org> 2011-06-21 10:51:55 UTC --- (In reply to comment #5) > Apparently, gmp's scripts create a gmp.h file when configure is run, but the > gmpxx.h wrapper is copied only when a command "make install" is issued, so > that > gcc multi-stage compilation process may not have it, and this as soon as mpfr > (or mpc, I can't remember) needs to link to gmp. The failure telling that > gmpxx.h was missing occured during a configure script in mpfr (or mpc, again). gmpxx.h is part of the GMP source distribution, it's not generated > Hope this piece of information is useful. :-) Not really, if you don't say which versions of GCC and GMP/MFPR/MPC you're using, and your exact configure command, then it's not reproducable or verifiable. It also seems to be completely unrelated to this bug report, which is about segfaults (almost certainly due to faulty hardware) not incorrectly-detected system properties during configuration.
