Re: [Help-gsl] GSL Installation problem
Mon, 5 Oct 2009 10:07:55 -0700
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
but when i try the command
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.
