I have a program that runs on a remote headless machine (ie no X server) that has a memory leak. I was able to install gperftools and ran the heap checker which found the leak.
My problem is I can't install pprof on the remote machine because of all the graphics libraries required so I copied the generated .heap file onto a different machine that does have pprof installed. This machine also has all the same libraries as the rmote machine.
I tried running the pprof command suggested by the heap checker, but with --text instead of --gv
$ pprof <my_bin> <heap_file> --inuse_objects --lines --heapcheck --text
but it complains about a failed curl command
Using local file <my_bin>.

So my questions are: is what I am attempting even possible? is there a different pprof command I should be using? what is the curl command about?
Thanks,
