I'm having problems building gcc (c,c++, and FORTRAN compilers
chosen) under Cygwin. I downloaded gcc-4.1.2.tar.gz. I gunzipped it
to a directory, and untarred that. I created a subdirectory obj and
changed to that directory. (All this from within Cygwin.)
I ran
../gcc/configure -enable-languages=c,c++,fortran.
This ran successfully. I then attempted to build the compilers using:
make CFLAGS='-O' LIBCFLAGS='-g -O2' LIBCXXFLAGS='-g -O2
-fno-implicit-templates' bootstrap
Here's most of the output - it fails trying to build libiberty.a.
Note that there is no directory
../build-i686-pc-cygwin/ in my system. I suppose configure has made a
mistake somewhere in expecting to find such a directory. I'd
appreciate any suggestions or ideas on who to ask!!
