Profiling Error

[Dinosaur]

Hi All

Reading another thread prompted me to try -profile , since I have not used it since
my last Windows project.

The compile command is simply: fbc -v -profile
Then when I run the program and then exit it, I get the following error :
_mcleanup: gmon_out: Permission Denied.

I have checked the permissions and they are OK.
Is this a problem with execute permissions of _mcleanup or with writing the gmon.out.
The gmon.out file was never created when I went looking for it.

Anyone have any ideas as to why the error ?

Regards

Hi All

Thanks for the reply dodicat.
I am using Linux Mint 18.3

If I run the profiled program as the normal user, there is the error.
If I run it as Root, there is no error, BUT it puts the gmon.out in a totally unrelated folder. /media/username/gmon.out

When running gprof as root however I get an error:
gprof: gmon.out: not in executable format.

Read somewhere that there may be different versions of gprof, with one on of them dedicated to FB ??

Will search and see.

EDIT: Typical mistake of assuming that the file to run with gprof is gmon.out.
Instead of gprof MyProgram > MyProgram.txt which then causes gprof to look for gmon.out
