I've been trying to build gcc 4.2.2 using a script which starts with a blank environment and explicitly sets each needed variable. I've installed gmp and mpfr and am specifying those installations with --with-gmp and --with-mpfr. On two different systems, I've found that unless LD_LIBRARY_PATH contains the library directory of the previous gcc, I get the following error:
checking whether the GNU Fortran compiler is working... no
configure: error: GNU Fortran is not working; the most common reason
for that is that you might have linked it to shared GMP and/or MPFR
libraries, and not set LD_LIBRARY_PATH accordingly. If you suspect...
The following settings (two different systems, /path/to/usr/lib is where gmp and mpfr are installed) result in a successful build
Why does the newly-compiled gfortran need this old path in LD_LIBRARY_PATH to function?
