Hi

Well, let’s start saying that I’m new at Linux and I’m trying to start on Gromacs as well.

I’ve been trying to install Gromacs 4.0 in my computer (laptop ACER Aspire 4530, AMD Athlon 64X2) running Mandriva 2009 and I just got stuck at the very beginning.

I read I need a compiler, so I downloaded GFortran (gcc-trunk-x86_64.tar, from http://gcc.gnu.org/wiki/GFortranBinaries64Linux).

I unpacked the package using the command “tar xvfz gcc-trunk-x86_64.tar.gz”. A folder was created inside the folder I keep all the programs I am using (at “Home”).

After that, I tried to install Gromacs 4.0, and the follow screen shows up:

checking build system type… i686-pc-linux-gnuoldld

checking host system type… i686-pc-linux-gnuoldld

checking for a BSD-compatible install… /usr/bin/install -c

checking whether build environment is sane… yes

checking for a thread-save mkdir –p… /bin/mkdir -p

checking for gawk… gawk

checking whether make sets $(MAKE)… no

checking how to create a ustar tar archive… gnutar

checking for cc… no

checking for icc… no

checking for xlc… no

checking for gcc… no

configure: error: no acceptable C compiler found in $PATH

See ‘config.log’ for more details.

I know the problem is probably due to some error in Fortran installation (it should be moved to the “path”), but I have no idea how to solve it. What should I do?

The error has nothing to do with Fortran; the problem is quite clear - the configure script cannot find a C compiler.

Try typing "echo $PATH" at the command line to see which your PATH variable includes. If it does not include the directories within $HOME where you are installing software, then add this directory to your PATH:

PATH=$PATH:$HOME/software/bin (for example)

Also, when you are finally able to install Gromacs, at least install the newest version (4.0.3) to get the newest bug fixes and revisions.

Thanks

Sir Guerra
