Hi,
I've just tried to install SAGE 2.7 from the source. The computer is
a dual Xeon (64-bit) Dell running Fedora 6.
It seems that the problem is Fortran.
It seems that system has gfortran installed:
boole[/scratch/local/sage-2.7]$ locate gfortran
/scratch/local/sage-2.7/spkg/installed/gfortran-20070719
/scratch/local/sage-2.7/spkg/standard/gfortran-20070719.spkg
/usr/bin/gfortran
/usr/lib/gcc/x86_64-redhat-linux/4.1.1/libgfortran.a
/usr/lib/gcc/x86_64-redhat-linux/4.1.1/libgfortran.so
/usr/lib/gcc/x86_64-redhat-linux/4.1.1/libgfortranbegin.a
/usr/lib/gcc/x86_64-redhat-linux/4.1.1/32/libgfortran.a
/usr/lib/gcc/x86_64-redhat-linux/4.1.1/32/libgfortran.so
/usr/lib/gcc/x86_64-redhat-linux/4.1.1/32/libgfortranbegin.a
/usr/lib64/libgfortran.so.1
/usr/lib64/libgfortran.so.1.0.0
/usr/share/doc/gcc-gfortran-4.1.1
/usr/share/doc/gcc-gfortran-4.1.1/ChangeLog.bz2
/usr/share/doc/gcc-gfortran-4.1.1/ChangeLog.gomp.bz2
/usr/share/doc/gcc-gfortran-4.1.1/ChangeLog.libgfortran.bz2
/usr/share/info/gfortran.info.gz
/usr/share/man/man1/gfortran.1.gz
I've got (in the log):
-----------
checking for gfortran... gfortran
checking whether we are using the GNU Fortran 77 compiler... yes
checking whether gfortran accepts -g... yes
....
checking for gfortran option to produce PIC... -fPIC
checking if gfortran PIC flag -fPIC works... yes
checking if gfortran static flag -static works... yes
checking if gfortran supports -c -o file.o... yes
checking whether the gfortran linker (ld -m elf_x86_64) supports
shared libraries... yes
------------
so, it seems that the installer found gfortran. On the other hand, it
seems that SAGE install its own version later:

Then it tries to install f2c-1, but fails:

^^^^^^^^^^^^^^^^^^^^^^

This is at the very end of the output of the installation.
If I triy to start SAGE:
boole[/scratch/local/sage-2.7]$ ./sage

I've checked $SAGEHOME/spkg/build/f2c-1/spkg-install, and it seems
that I could copy
"/usr/lib/gcc/x86_64-redhat-linux/4.1.1/libgfortran.a" to
"$SAGE_ROOT/lib/libgfortran.a", but I thought I should check first and
report a potential bug.
Thanks,
Luis
P.S.:
* Could I use the precompiled? (The README.txt says "This binary will
*only* work on AMD 64-bit computers", but I think 64-bit Xeons use the
AMD64 kernel, so I wasn't sure... )
* The README.txt in $SAGEROOT says
"If you have a machine with n processors, say,
type
export MAKE="make -j4""
Shoud it say "If you have a machine with *4* processors"?
