------- Comment #2 from thomas dot orgis at awi dot de 2009-06-29 12:51 -------
Thanks for confirming that it _should_ work.
Now the question is: What is wrong with the installation on my system so that
it does not work?
I see that gfortran is apparently trying to preprocess the .F95 files, but that
cc1 call goes wrong.
Is this perhaps a problem with installing gcc, g++ and gfortran in separate
steps? I mean, the preprocessor itself does not have a problem with
f95-cpp-input ... so that does not seem so plausible.
This is essentially our gfortran install script -- is there something wrong
with that?
#!/bin/bash
sed -i -e "s/lib64/lib/" gcc/config/i386/linux64.h &&
if [[ $CROSS_INSTALL == on ]]; then
OPTS="--host=$HOST $OPTS"
else
OPTS="--build=$HOST $OPTS"

cd $SOURCE_DIRECTORY.bld &&

cd $SOURCE_DIRECTORY.bld &&
make -C gcc lang.install-common lang.install-man &&
install -c gcc/f951 ${INSTALL_ROOT}/usr/libexec/gcc/$HOST/$VERSION/ &&
sedit 's,lib64,lib,' $HOST/libgfortran/Makefile &&
make -C $HOST/libgfortran/ install &&
# specs file stuff
local SPECSDIR=${INSTALL_ROOT}/usr/lib/gcc/$HOST/$VERSION &&
mkdir -p $SPECSDIR/specs-local &&
cp $SCRIPT_DIRECTORY/specs_fortran $SPECSDIR/specs-local
rm_source_dir $SOURCE_DIRECTORY.bld &&
local SPECSDIR=${INSTALL_ROOT}/usr/lib/gcc/$HOST/$VERSION &&
cat $SPECSDIR/specs-local/* > $SPECSDIR/specs
# end of script
The specs_fortran file, being incorporated into the common specs file looks
like that (I am wondering: Are we supposed to ship that file -- I did not write
the build script myself)?):
