Determine Compiler Version used

Accelerated Computing HPC Compilers Legacy PGI Compilers
1

I’ve encountered an older program that was compiled with Portland Group Fortran 90 compilers. However, I’m unsure as to the exact compilation date of the program, and can not determine what pgf90 version was used (due to past updates of PGI).

Given just the executable, is there any way I can determine what version of Portland Group was used to compile the binary?

Thank you

Hi mjohnson,

Starting with the 6.1-4 release of the compilers, we did start embedding the compiler version into an object’s .comment section. An executable will have the version numbers from all the objects, including runtime libraries.

To retrieve this info, use the following objdump command.

% pgf77 -V6.1-4 hello.f -c
% objdump -s --section=.comment hello.o | grep PG
 0000 00504746 544e2036 2e312d34 00        .PGFTN 6.1-4.
% pgf77 -V6.1-4 hello.o -o hello
% objdump -s --section=.comment hello | grep PG

Hope this helps,

Hello Mat,
Thank you for the reply. Unfortunately, I know the PGF version used would have been pre 6.1, most likely 6.0 or 5.1 -I’m not certain which though. Any suggestions for this situation?

Thank you,
Matthew

Hi Matthew,

Unfortunately, there is no practical way to get this information prior to 6.1-4.

Sorry,
Mat
