Unable to profile some programs on linux (XXX is not a valid application) about radeon_compute_profiler HOT 4 CLOSED

Currently, the profiler only supports valid ELF executables. I've logged a feature request so we can investigate adding support for scripts as well.

Also, I tried profiling /usr/bin/python2.7 and on my system (an Ubuntu 16.04 system), rcprof is able to profile it. I don't see the same "/usr/bin/python2.7 is not a valid application" error you reported.

I use archlinux.

Some applications get the "is not a valid application" error, some others don't. I figured out when I recompile applications I compiled a few months ago, they now get the "is not a valid application".
I fail to find an explanation.

EDIT: with readelf It looks like the executable that get the error have the flag 'DYN' instead of 'EXEC'.

EDIT2: It looks like recent compilers have -pie default (which gives DYN). Enforcing -no-pie gives EXEC and rcprof runs. The correct fix should be have rcprof accept DYN too.

There was a change included in v5.2 which relaxes the check for a valid ELF executable. Could you try the 5.2 release to see if it works better for you?

I confirm the issue is fixed with the last version of CodeXL (2.5).

I close the issue.
