Instralling g95 for Red Hat Linux
in [Fortran]
|
From: jaafar on 25 Jun 2008 16:57 Hi All I am wondering if any one can help me on how to instrall g95 for Linux! These are the steps I followed: 1. I created folder: WRF then subfolder:g95 2. I downloaded the i686-pc-linux-gnu-g95 from http://www.ftp.g95.org/ and pasted in wrf\g95 3. I used the following commends: [Mahmoudi(a)mahmoudi-ecd ~]$ cd wrf [Mahmoudi(a)mahmoudi-ecd wrf]$ cd g95 [Mahmoudi(a)mahmoudi-ecd g95]$ tar xvfz g95-x86-linux.tgz g95-install/ g95-install/INSTALL g95-install/G95Manual.pdf g95-install/bin/ g95-install/bin/i686-suse-linux-gnu-g95 g95-install/lib/ g95-install/lib/gcc-lib/ g95-install/lib/gcc-lib/i686-suse-linux-gnu/ g95-install/lib/gcc-lib/i686-suse-linux-gnu/4.0.3/ g95-install/lib/gcc-lib/i686-suse-linux-gnu/4.0.3/libgcc_eh.a g95-install/lib/gcc-lib/i686-suse-linux-gnu/4.0.3/libf95.a g95-install/lib/gcc-lib/i686-suse-linux-gnu/4.0.3/libgcc_s.so.1 g95-install/lib/gcc-lib/i686-suse-linux-gnu/4.0.3/f951 g95-install/lib/gcc-lib/i686-suse-linux-gnu/4.0.3/crtbeginT.o g95-install/lib/gcc-lib/i686-suse-linux-gnu/4.0.3/crtbeginS.o g95-install/lib/gcc-lib/i686-suse-linux-gnu/4.0.3/libgcc.a g95-install/lib/gcc-lib/i686-suse-linux-gnu/4.0.3/crtendS.o g95-install/lib/gcc-lib/i686-suse-linux-gnu/4.0.3/crtend.o g95-install/lib/gcc-lib/i686-suse-linux-gnu/4.0.3/libgcc_s.so g95-install/lib/gcc-lib/i686-suse-linux-gnu/4.0.3/crtbegin.o g95-install/lib/gcc-lib/i686-suse-linux-gnu/4.0.3/cc1 [Mahmoudi(a)mahmoudi-ecd g95]$ ln -s /wrf/g95/g95-install/bin/i686-pc- linux-gnu-g95 /bin/g95 ln: `/bin/g95': File exists [Mahmoudi(a)mahmoudi-ecd g95]$ g95 bash: g95: command not found [Mahmoudi(a)mahmoudi-ecd g95]$ However, as you can see when I type g95, it says command not found. I am wondering why? Is my installation okay! For you information I am using Red Hat Linux with 64bits I do need your help in installation g95 in my system. I look forward to hearing from you Regards Jaafar

A simple (and usual) possibility would be to create a link named g95 in some directory already present in your PATH variable. Usually, it might be /usr/local/bin. Try: ln -s /wrf/g95/g95-install/bin/i686-pc-linux-gnu-g95 /usr/local/bin If you are using bash as shell, that should be enough. Try to use g95 to compile a file of yours. Giorgio

From: Alois Steindl on 26 Jun 2008 03:13 Hello, that is not a fortran question, but concerns the basic usage of unixoid systems. I would strongly suggest that you get a good introduction to Linux/Redhat/Unix and work through it right now. Otherwise you will run into problems very frequently. Some explanation for your problem: When the shell starts, it searches through the directories listed in the PATH variable and remembers the executable files in these directories. If you add new programs to these directories, the shell doesn't know about that (although it just helped you to put it there), so you could call "hash -r" in bash or "rehash" in the tcsh. You could also simply start a new shell window, then the shell should know about the new program. If you plan to do more programming, you should at least learn about the shell yiu are using and about make. Good luck Alois
