unknown suffix ignored

I have installed the PGI (32bit-trial license) compiler on Fedora Core 5. It installs fine but complains that I have an unknown version of glibc (ERROR: unknown glibc version (2.4)). When I try to compile something I get:

einstein-[nikhil] 46) pgf90 test.f90
pgf90-Error-file with unknown suffix ignored: test.f90

when I try the -V option, it says it’s an unknown switch. I “which” command gives the proper executable:

einstein-[nikhil] 49) which pgf90

and -dryrun gives:

einstein-[nikhil] 51) pgf90 -dryrun test.f90
Reading rcfile /usr/pgi/linux86/6.1/bin/pgf90rc
Reading rcfile /usr/pgi/linux86/6.1/bin/pgftnrc
pgf90-Error-file with unknown suffix ignored: test.f90

Anyone have any ideas what might be wrong? Help would be much appriceiated.


There are a few questions here on FC5. The installation is failing for most people, hence the compiler errors. We are actively working on it and should have support for FC5 and glibc 2.4 in our products soon.


Do you have created a patch in order to solve that problem ? I’m using Fedora Core 5, and I’d like to compile my programs with your compiler in 64 bits.

Thank you

Hi benj63,

The latest release, 6.1-5, supports Fedora Core 5.


Thank you !

I’ve alredy installed pgi 6.1.5. but when i try to create an executable file ( grib2dp), from grib2dp.f90, it just give an error like this:

[qalberto@localhost CPTEC]$ /usr/local/pgi/linux86/6.1/bin/pgf90 grib2dp.f90 -o grib2dp
pgf90-Error-file with unknown suffix ignored: grib2dp.f90
pgf90-Warning-Unknown switch: -o
pgf90-Error-file with unknown suffix ignored: grib2dp
[qalberto@localhost CPTEC]$

what to do?

Whwn i try to create an executable file "grbconv from grbconv.c, it gives me the error:

[qalberto@localhost CPTEC]$ /usr/local/pgi/linux86/6.1/bin/pgcc grbconv.c -o grbconv
pgcc-Fatal-unable to find any RC file
[qalberto@localhost CPTEC]$

Thanks for the expected help

Hi Chaile,

It’s most likely that your installed failed for some reason. What OS are you using? Did the installer give any error messages? What is the output of “pgcc -dryrun” and “/lib/libc.so.6”?

Hi mkcolg

I’m using Linux 8.0. The installation was completed and it created a 15 day evaluation license. the output of “pgcc -dryrun” is:

[qalberto@localhost bin]$ pgcc -dryrun
pgcc-Fatal-unable to find any RC file
[qalberto@localhost bin]$

and the output of “/lib/libc.so.6” is:

[qalberto@localhost bin]$ /lib/libc.so.6
