(MPFR is the same way.)
I don't think that applies in the case of Cygwin, since Windows does not know anything about LD_LIBRARY_PATH. (Cygwin emulates it for dlopen() but I don't think that's relevant here.) I can say that I was able to successfully build and test the 4.1.2 20070129 (prerelease) version under Cygwin using the Cygwin-packaged mpfr (2.2.1) and gmp (4.2.1) without any setting of LD_LIBRARY_PATH and it passed all tests except for gfortran.dg/secnds.f which is a known bug. So unless the released 4.1.2 tarball differs from the RC1 tarball in this area, it's something else and not a gmp/mpfr/libgfortran problem. In order to debug this, poster should run the faulting series of commands and see what the errors are, i.e.: for k in 4 8 10 16; do echo " real (kind=$k) :: x" > tmp$$.f90 echo " end" >> tmp$$.f90 /usr/local/src/branch/objdir/./gcc/gfortran -B/usr/local/src/branch/objdir/./gcc/ -B/usr/local/i686-pc-cygwin/bin/ -B/usr/local/i686-pc-cygwin/lib/ -isystem /usr/local/i686-pc-cygwin/include -isystem /usr/local/i686-pc-cygwin/sys-include -I . -Wall -fno-repack-arrays -fno-underscoring -c tmp$$.f90 done Brian
