Coverage analysis on Windows

Coverage analysis on Windows

[ManU]

Hello,

I am looking for a windows tool which enables to display gcov (gcc
3.4.4) coverage results.
Would you know one ?

I have tried lcov, but it isn't ported for Windows ...

Thanks for your help !

Cheers,
ManU

'lcov' is just a set of perl scripts. They can be executed in any 
Windows system with a perl interpreter (I've just tested it).

You are welcome.

lcov processes unix-style paths.
However, our version of gcc and gcov (gcc 3.4.4) encripts windows-style
paths into .obj, .gnco, .gda and .gcov files. Therefore, lcov does not
manage them correctly ...

lcov would need to be fully ported to windows ...

If you have knowledge of any port of lcov or any other tool, please let
me know ;o)

It works on Cygwin. Cygwin is a Windows port of a large set of GNU 
utilies. Includes a bash shell that provides a unix-like environment.
The perl interpreter (and any other utility) from Cygwin understand both 
forward and backward slashes as path delimiters.

It works OK in my WinXP machine via Cygwin. I've just tested a minimal 
example. Perhaps it needs more thoroughly test. Can you provide a sample 
code that fails on your machine? I'm willing to test it in my machine.

BTW, which Windows port of gcc are you using? Cygwin? GNAT? MinGW?

Sorry, no.

Get the Cygwin version of gcc; it does Unix paths. The GNAT in the
Cygwin distribution is a little broken, but it may work well enough
for you.
