I might have posted this to gcc-help, but that I was pretty sure I had the proper devel packages -- leastwise for the ones that had devel packages. I could also have read the configure.ac source code, but I felt that problems requiring that level of sleuthing was probably more a GCC developer question rather than a newbie question. I did go ahead and patch the http://gcc.gnu.org/wiki/GitMirror web page to explain that the "git svn init" command shown there actually requires the user name, rather than it just being "okay". Anyhow, I had two of the three devel packages and I read the error message: > checking for the correct version of gmp.h... yes > checking for the correct version of mpfr.h... yes > checking for the correct version of mpc.h... yes > checking for the correct version of the gmp/mpfr/mpc libraries... no > configure: error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 0.8.0+. > Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify > their locations.

As you can see, all the headers were found, but the configure tests inaccurately detected a failing version of one or more of the libraries. I believe this to be a configure test problem, whether caused by things that ought to be done differently in the configure test or whether caused by stuff stripped out of the distribution (e.g. a libmpc2.pc file). Should I ask gcc-help@xxxxxxxxxxx for assistance? Your help is greatly appreciated! Thank you. Regards, Bruce
