Re: Free AMD Core Math Library (BLAS/LAPACK) + Ada

[Ada novice <shai.lesh@gmx.com>]

I did a fresh install of GNAT GPL 2011 and took away the GNAT that is packaged for Debian. The latter is problematic on my linux and I cannot explain why.

When I now do which gcc, I get /usr/gnat/bin/gcc

Issuing a gnat -v returns me:
gnat: Unknown command: -v

I have seen many places people using gnat -v but I have never make this work and the documentation doesn't say that -v will give the version of gnat.

I have now also installed gfortran-4.6.

gfortran-4.6 -v
Using built-in specs.

and locate libgfortran gives

When I go to Nasser's page at step 11:
http://12000.org/my_notes/ada/index.htm

The makefile now seems to work with gnat but the lgfortran cannot be located:

make all
gcc -c cxbbase.ads
gcc -c cxbbase.ads
gnatmake cxbi.adb -largs ifinc.o -lgfortran -lm
gnatbind -x cxbi.ali
gnatlink cxbi.ali ifinc.o -lgfortran -lm
/usr/gnat/libexec/gcc/i686-pc-linux-gnu/4.5.3/ld: cannot find -lgfortran
collect2: ld returned 1 exit status
gnatlink: error when calling /usr/gnat/bin/gcc
gnatmake: *** link failed.
make: *** [cxbi] Error 4

Anything that I must adjust in my path or something else?


Thanks,
