Download old Intel® Fortran Compiler

[Hapo]

Hello,

I need to compile a legacy code that seems to need a variable  IFORT_COMPILER11 that match a ifortvars.csh file.
I suppose I need to install Intel Fortran Compiler 11 but I do not find the way to install old version of Fortran Compiler.

Where can I get them ?

Regards,

Hapo

Install the current 2024 version. Edit the script that looks for IFORT_COMPILER11 and ifortvars.csh and replace these with the path to the current version's setup script. (The current version ought to define IFORT_COMPILER24 but doesn't - a bug that will be fixed in a future update. See Use the setvars and oneapi-vars Scripts with Linux* (intel.com) for details.

What is not said, is it is always faster to fix the modern small errors than attempt the perversity of trying to obtain that which is forever gone. If you attempt the fix it is always easier for other people to help who will have the modern and not the archaic compiler version on their computers.  Batch files merely point at the exe.  ONEAPI has a good system, whoever thought of it needs to be congratulated. 

Also compilers theoretically get better at detecting code errors, -- sometimes, but sometimes as was noticed by the Norse, the gods are perverse with their humour.

... and don't forget that security issues are also fixed with each new compiler version. Intel strongly recommends users more to the latest versions.

@Hapo, since you are moving to a new version of the Intel Fortran compiler, you may want to consider using ifx. ifort is deprecated and will be removed from new releases in late 2024. Here's a link to more information about that and tips on the transition to ifx.
