Intel Fortran Compiler

aend · 05-19-2010, 08:23 AM

Hi,
I want to compile MFiX which is a simulation software.
Therefore, I installed the Intel Fortran Compiler Ver. 11.x
When compiling, I can only choose between Ver.9.x and 10.x.

This is a part of the error message when choosing either:
make: ifort: Command not found
make: *** [param.mod] Error 127

Is there a possibility to link the program to the newer compiler version?

I'm using Centos 5.4 and, like in this forum, I'm a newbie.

Thanks for any ideas!

Does MFiX require the Intel FORTRAN compiler? If not, why not just use the GNU compiler? Then you can select the FORTRAN version you wish to use to compile the program. (The various flavors of GNU FORTRAN should be in the Centos repositories.)

MFIX does not require the Intel fortran compiler. Actually, I can choose between

Quote:

MFIX Compilation directives available for following compilers:
==============================================================
[1] Portland Group Linux Fortran Compiler (pgf90)
[2] Intel Fortran Compiler version 9.X (ifort)
[3] Intel Fortran Compiler version 10.X (ifort)

As far as I know, the Portland Group Compiler is not for free. Thats why I'm bound to the Intel Compiler.

I don't think that the error message helps you, but I can post it anyway.

Thanks for the quick reply!

Assume ifort installed, like : 1) cd l_cprof_p_11.0.083_ia32/
2) su , 3) sh install.sh

... which means, you have got /opt/intel/Compiler/11.0/083/bin/ia32/ifort
... ( If it is 32 Bits OS.)

cd /usr/bin/
ln -s /opt/intel/Compiler/11.0/083/bin/ia32/ifort
... Then 'ifort' is in a system path.

ok, that helps

thanks a lot.

apparently, that was quite a beginner question.
why do i have to set the link? is this a standard procedure? could you tell me where i can learn more about that?

Is this a standard procedure ?

As "Ifort" isn't a standard program, it is not a thing you will meet very often.

"Default" software, an example is Java : The install scripts for the available
rpm ( for CentOS the Scientific SL55 (sun)jdk is usable ) make a link 'java' to
/etc/alternatives/ . This can be done manually too for programs not having this
mechanism :

Code:

/usr/sbin/alternatives --install /usr/bin/java java /usr/java/jdk1.6.0_20/bin/java 2

Afterwards : # /usr/sbin/update-alternatives --config java
.. which will then create the link /usr/bin/java
( If not already done automatically at the package install.)
..

Other ways to call 'ifort' , 1) The full path ,,, /opt/intel/Compiler/11.0/083/bin/ia32/ifort
2) export PATH=/opt/intel/Compiler/11.0/083/bin/ia32/
3) Write a line with the new path in e.g. /etc/profile ..
..... But these are all a little more difficult, I prefer the softlink to /usr/bin/
..
