HOWTO: Install Intel Fortran 9.0

[Omni-Vi]

Hi All,
I had the same problem of not being able to install Intel Fortran Compiler under Dapper. The error was

...
install_fc.sh can't identify your machine type, glibc, or kernel.
...

Some of you had the same problem.
Solution:
The installation script install_fc.sh tries to determine the GLIBC version within the function GET_SYSTEM_REQUIREMENTS () {...} with the following statement (lines 1506-1510):

if [ "$RPM_NOT_FOUND" = 0 ] ; then
  GLIBC="$(rpm -qa | egrep -e 'glibc-2\.2\.4' -e 'glibc-2\.2\.5' -e 'glibc-2\.2\.93' -e 'glibc-2\.3' -e 'glibc-2\.4' 2> /dev/null )"
else
  GLIBC="$(ls /lib/libc-* | grep -e '[.]so' | sed s@'\(.*\)\(\.so.*\)'@'\1'@g)"
fi

Now the thing is, if you are using Debian/Ubuntu and you have alien, you also have rpm. BUT the rpm database that holds a list of all installed packages under eg. SUSE is empty under Ubuntu, since it is not used.
Therefore, the GLIBC variable is left empty (rpm -qa gives back nothing). The second call (ls /lib/libc-...) should be used but is not since rpm is installed.

Okay, what do we do about it?
First of all, you can not uninstall rpm for alien depends on it. What we can do though, is to change the install_fc.sh script so that it does not use rpm. This is simple. Just go to line 226 in install_fc.sh (the IS_RPM_PRESENT () {} function) and look for

RPM_NOT_FOUND=$?

.
Change it to

RPM_NOT_FOUND=1

and install.sh should work just fine. No need to convert any package by hand, the installer will do that for you.

I would be happy to hear if this works for you, I hope it will
Ciao

Ps: The line numbers are for the Intel Fortran 9.1 Compiler. You might have to adapt them for 9.0 or C Compiler. Thats why I gave you the function names as well.

it works

I am newbie of ubuntu and linux. I follow the guide of installing Intel Fortran. I get the lates version of fortran 91.036, it's seem to be well installed, but, as a newbie, I don't know how to access the .bashrc to insert some code as instructed.
Please helme, thanks,

[alin.elena]

that's simple

open a terminal window.

than

cd

to be sure that you are in you home directory

than

vi .bashrc

you can substitute

vi

with your favorite text editor.

and now at the end of the file you add the source commands.

One more "stupid" question, how ho run fortran? bacause I did not find the program under Application menu. Sorry!!

[alin.elena]

intel fortran is a compiler. a tool to generate binary files from source files.

let us assume that you have a fortran 90 source file test.f90
the simplest will be somthing like

program hello_world
implicit none

print *, "hello world"
end program hello_world

fortran will help you to generate an application that will write on the screen (standard output) "hello world".

for that in the command window you will do something like that

ifort -o test test.f90

than

./test

and that's all you have created the first fortran application.

p.s. there are plenty of resource on the web about how to programme using fortran

It was mistake on the path. It works.

i could install succesfully ifort, but i should say that theres one more step for non-english ubuntu boxes, i mean, if you try to execute ifort then it will say something like

ifort: error: could not find directory in which g++ resides

i could find at intels webpage an interesting set of solutions, but i just had to set the LC_ALL environment variable to C

e.g export LC_ALL=C

note for newbies(like me): this variable should be modified at etc/enviroment

Hello every one

I tried to install Intel Fortran free compiler "9.1" on my laptoop.

during the installation I get this message.
----------------------------------
Problems with Fortran compiler: Output not equal to < Hello, World! F90>
See /tmp/test_fc.7127.log for details.

NOTE: If using a FLOATING or NODE-LOCKED license file, ignore this message.
Press ENTER to continue.
---------------------------------

Is it NORMAL?
Can you please help me?
Thanks

in response to the previous poster this is normal, the install script tries to actually compile a little test program and check the output (that's the whole hello world thing). Sadly because the variable setting scripts(ifortvars.sh) in the intel/fce/bin dir don't quite work with ubuntu.

I think this is because they start with #!/bin/sh while having some syntax which assumes bash. On ubuntu 6.10 #!/bin/sh->dash it's a symlink to dash which seems to not quite work properly with some of the shell commands. I'm no bash/dash guru but this seems stupid to me. Anyway you can fix it by changing it to directly invoke bash: #!/bin/bash.

I managed to get the C++ compiler installed just fine like this but when i tried to get ifort going i get this error:

exec: 34: -a: not found

Anyone know wha's going wrong there?

Thanks
