对从远程机器收集的数据运行 pprof？

Question

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>.    
Use of uninitialized value $host in substitution (s///) at

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,

Simply use go version of pprof. In this case I suspect what happens is that arg parsing doesn't really support flags at the end (I suspect go's has this bug as well). This use case of pprofing with binary and pprof file is definitely supported.
