We have installed Red Hat 6.0 and 6.1 numerous times on numerous machines and most of the fortran programs (that compile nicely and run on a sun) we have compile but then dump with a segmentation fault when run. An ldd of the executable gives "this is not dynamically linked". We have also installed several other f77 packages for linux and they don't work either. Having said all that we have 1 machine that when reinstalled with 6.0 or 6.1 consistently (and we have occasionally fluked the odd other machine but on a 2nd installtion of RedHat fails) compiles and runs ALL the programs but we have no idea why. Also, an executable from a machine that doesnt work will run on the 1 good machine (P 166hz). The one machine we really need this to work on (Dell Notebook) continually fails (so far we have tried installing the operating system 6.0 and 6.1 > 10 times.
Could you be more specific about what programs are having a problem? Does it happen on short test programs? If so, all of the ones you tried or just some? For example, I tried the following on a 6.1 system and it worked for me: $ cat foo.f PRINT *,'Hello, world' END $ f77 -g foo.f $ ./a.out Hello, world $ Also, what CPU is in the machines which don't work? I'm not sure I can do a lot if the problem doesn't show up on my machine, but I can see if anything springs to mind with the above information.
Changing this to WORKSFORME pending further information (as described in my previous comment).
