Two Compilers installed but just one works

[P__Bartels]

I've got two Versions of a Fortran Compiler: 11.0.072 and 11.7.258, but since I installed the 11.7.258 Version I can't use 11.0.072 anymore.
The problem is: I need both of them...

I also use Visual Studio 2008 in case that this is important.

You can use both from the command line, but only one IDE can be in Microsoft Visual Studio at once. Usually realeases with the same major version can use the later IDE. What problems do you encounter when trying to use them. You can select which compiler is being used inside Visual Studio under

Tools => Options => Intel Fortran => Compilers => Selected Compiler

I work in the same departement as P. Bartels.

We have to use various compiler versions for our customers. One says, we have to build our program with the 11.0.072 compiler.

He got a new license, so we installed the 11.0.072 compiler first and afterwards12.1 Update 7 on our VS2008 system. But thenthe 11.0.072 compiler is kicked out of the list. In "former" times we could select the compiler via the options menu like you described it Wendy, but now only Versions >= 11.1 are supported.

Why did Intel changed that behaviour?

You will only be able to see compilers that the IDE installed in Microsoft Visual Studio supports. When you have the 12.1 IDE installed it does not see the 11.0 compiler since it won't work with it. We usually change IDEs enough between major versions of the compiler 11.x to 12.x for instance, that the IDE no longer works with the older compiler. Updates within a major version, 12.1 update 6 to 12.1 update 7 would work with the later IDE.

This restriction is due to new and changed compiler options with the a major release in the IDE being supported by the compiler invoked. We can only install one IDE at a time into Visual Studio.

The overall behavior has not changed.

Hello,

i had a similar problem. For me it work the other way around. I have first installed IVF12.1 Update7 with the VS2010Shell, then VS2008 and then IVF 11.1 (integrating in VS2008). Now it works. Both Version inside their VS can be used via IDE. On an computer with win vista 32bit is was even able to install cvf as a third compiler (with IVF 12.1 ivf 11.0 and cvf as the last installation).

If you first install VS2008 then IVF 12.1. (integrating in VS2008 and installing VS2010Shell) then IVF 11 (integrating in VS2008) a additional repair of the VS2008 installation is needed. But then you can use both IVF inside the 2008 IDE and IVF 12.1 additionally in VS2010Shell.
