gcov with Ada question

gcov with Ada question

[James Squire]

I've been trying to use gcov with my Ada application built with GNAT. 
The problem is I have source files in two different directories, object
code in a third directory, and wanted to run gcov from a fourth
directory.  The gcov documentation I have found has been a little
confusing, but by trial and error I discovered that the only way gcov
would work was if I was actually in the directory where GNAT put my
object code when I run gcov, and then it can find the coverage files in
the current directory and use either the .o or the .ali file to find the
source file, but I noticed that some of the gcov files get created more
than once (representing packages that are withed more than once), and
each time the previous file is trashed.  So I tried using the -l option,
but then it was unable to form the extended file name correctly ... all
because I don't have all my sources and objects in one directory, which
is what it seems to want.

Is there any other coverage tool out there I might use that might be a
little more flexible?  Even if I do copy all my source files to one
directory and rebuild my application in place, the gcov -l option will
still fail when it tries to create a gcov file for a GNATPRO library
package (I'm running on a PC).

Any suggestions would be welcome.
