Hello dear friends:
I am an almost newbie to USING LINUX PLATFORM.Because I am doing research by running a big model, so Recently, I need to install G95 and ifort on the Fedora linux paltform. But I failed several times. So, could any friend be kind enough to tell me the detailed step by step to install G95 / ifort, for example, I appreciate much about that. As a newbie, sometimes it is hard to imagine how much difficulty he has to run something there.
Thank you at first!

No one here is going to tell you step-by-step on how to do something. Steps vary depending on user's setups and it's insulting to those of us who have found step-by-step instructions in google. When your install failed, explain what happened that indicated that it failed.

The installation of the two cited fortran compilers are straightforward. The G95 project provides binaries. Just download them, extract the archive under /usr/local and make a symbolic link to the executable in /usr/local/bin to make g95 available to all users.

To install the Intel Fortran Compiler, just extract the downloaded archive, go into the installation directory and execute the install.sh script, then follow the instructions. You will have to provide the serial number or the license file you received from Intel.

Yum repoitories do not have packages named like g95 or ifort, though it has some other Fortran packages available. So I have to assume that you tried to start with some downloaded files. You should at least mention if you downloaded compiled binaries or source tarballs. Explaining your approach would also help to find out why your attempts have failed.

What does "doing research by running a big model" mean?

Hello, my friend:
Thanks for your response and advice. Could you be kind to tell me the meaning of /usr/local , because when I open my terminal, it shows home/naishi, is this the /usr/local. The other question is /usr/local/bin, does this mean I need to create a subdirectory bin under /home/naishi. Or, the /usr/local is already automatically set there?
I am waiting for your advice, thanks indeed!

Clue:

Yes we are here because we have a bit of that 'kindness' you expect. But honestly it looks like you are a way far yet. We don't hold lectures here, the space doesn't allow that. Do familiarize a little about Linux before trying to install a compiler. Read some tutorials. Use google. Most of us here are newbies like you, it just happened we had enough time to read, experiment and learn.

Read the basic of Gnu/Linux:

Goodluck.

Try to explore the directory tree, first looking at the directories under / and you will find out where /usr/local is located. Then, as suggested by malekmustaq, read a good tutorial about linux to find out what the various directories are supposed to be. To me you need some practice before trying to compile a Fortran program. Have you succeeded in installing g95 and/or ifort, anyway?

Hello Colucix:
Thank you for your assistance! Yeah, usually I use UNIX system to run a big fortran program such as a weather forecast numerical model, which is programmed usually by F90 and partly by C for some subroutines. So, I am quite familiar with vi editor and unix commands. But as for Linux I really need to learn more and I hope to learn more under your wonderful guys' help because I've realized the Linux system will be very promising in future and it has so great power and flexibility for one to use. I will try my best, and also hope your wonderful experts to be kind enough to give a hand, thank you indeed, Colucix!!!

I run ocean forecast numerical models on Linux machines without any clue. I compile them using the Intel Fortran Compiler, since they run on Intel Quad Core processors. Glad to be of help, if needed. Cheers!

Hello Colucix,
I am running WRF and MM5(as you know) on Fedora 7 platform by using ifort or g95. So, our professional fields are almost the same---atmospheric or oceanic models. So hope to learn things from you indeed!
talk you soon!
