installation after Intel Fortran

[Intel_C_Intel]

For benchmarking purposes, I had installed (and uninstalled) the Intel Fortran compiler. I have since tried to re-install Compaq VF 6.1.

I cannot properly install Compaq Fortran, after what appears to be a normal installation and reboot, when I try to compile a module from the MSDEV I get the message:

Intel Fortran Compiler Build Tool
The name specified is not recognized as an
internal or external command, operable program or batch file.
Error executing c:winntsystem32cmd.exe.

ARPRD.obj - 1 error(s), 0 warning(s)

Also, when I try to upgrade to CVF 6.5 the instalation won't start! (This may be unrelated though)

I've solved the Intel problem - I've copied back an old version of the project (.dsp) file. Now Compaq VF works.

Interesting. I haven't seen this problem myself. I know that the Intel installation establishes its compiler as the "Fortran" build tool, but I would have thought that reinstalling CVF would override that. One thing you can try, if problems persist, is to uninstall CVF, then delete the registry key SoftwareMicrosoftDevStudio6.0 under both HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER. Then reinstall CVF.

Exactly what happens when you try the upgrade?

I'd be interested in your comments on the Intel compiler and how it compares to CVF. For benchmarking, you really need to have CVF 6.5 to get the best out of the latest processors.

As in my previous reply, I managed to restore Compaq as the Fortran compiler by going back to a saved copy of the project (.dsp) file. Thank goodness for source code control!

The CVF 6.5 upgrade installation problem may have been because I had 6.5 previously installed (then I uninstalled CVF 6.1 from the control panel, ran the Intel tests, and re-installed 6.1). I managed to re-install it from the 6.5 disk by explicitly running setup.exe from the intel directory on the upgrade disk. I am now running 6.5a using the network upgrade.

My comparison with Intel Fortran failed: the compiler uses considerably more memory than Compaq (the Intel compiler used up to one gigabyte of virtual memory, and swapping madly to the page file). Some "standard" functions were not available, such as FLUSH and GETTIM, and the escape sequence in strings ("") caused problems with filenames and paths.

I am still looking for a way to improve compilation times (see earlier thread)!
