[Mingw-users] gcov with Eclipse project

[Greg C. <gr...@mo...>]

I am attempting to use gcov with a very simple Eclipse CDT project. I will
admit I am new to gcov, but I've been through their documentation and can't
find an explanation.
Test harness source file:
C:\some_folder\src\main.c

Object folders:
C:\some_folder\Debug\src

I am building with the gcc switches -fprofile-arcs and -ftest-coverage and
get the expected .gcda and .gcno files along with my .o files.

However, when I try and run (from C:\some_folder):
gcov src/main.c -o Debug/src

I get:
File `..\src\main.c'
Lines executed:99.04% of 209
..\src\main.c:could not open output file `..\src\main.c.gcov'

It looks like everything works fine in terms of analysing the graph files as
it gives the coverage summary (-f switch works too and give the per-function
breakdown). However, it fails inexplicably when creating the .c.gcov.

Can anyone help?
