Thank you so much dear Marco for your detail email reply.
i have tried what you advised me  as

 $ cd /home/marco
 $ mkdir -p var/build
 $ cd var/build
 $ tar --extract --gzip --verbose --file=/home/marco/gsl-1.9.tar.gz
 $ cd gsl-1.9

 $ ./configure --disable-static --enable-shared

up to this point it works error free  all the tar(command) and  configure
done successfully


but  when i try the command

$ make

it tells me

cant found make command .

in the gsl-1.9  directory  i have the  the makefile .

please let me know what could be the problem .

i am using  Mandriva spring 2009.

Regards

Shahid
