gconv problem in Luna under windows [message #1441099] Thu, 09 October 2014 08:59 Go to next message

Hi

I have a problem with gcov under Eclipse for C/C++, Luna 4.4.0 under windows. I use MinGC GCC toolchain. Compiler and linker flags are "-fprofile-arcs -ftest-coverage" (I have an error when trying to link with -lgcov flag).

gcov and gcc version is 4.9.1.

All needed gcc tools are visible (including strings) and I can create correct result file (*.gcov file) manually with gcov -o ./src/test1.gcno test1.c command.

The problem is that when I do "project->profiling tools->profile code coverage" program runs nad gconv tab opens in eclipse with correct coverage percentage but first line states "program runs = 0".
Next when I try to double click on file name to open a colored result file a standard C files opens with no gconv information.


When I work on C project I can open gcov tab using "project->profiling tools->profile code coverage" or double click on *.gcda / *.gcno file.

But when I work on C++ project I can open gcov tab only using "project->profiling tools->profile code coverage". When I double click on *.gcda / *.gcno file and click on I get:.

An error has occurred. See error log for more details.
Illegal char <:> at index 52: C:\Users\abc\Desktop\eclipse_test\test2\Debug\c:\mingw\include\c++\4.9.1\iostream

So eclipse build incorrect path here. But it doesn't explain why C project doesn't show gcov file result.

When I work on C project there are no information in eclipse's log file.
When I work on C++ project following errors are in log file:

This seems like Bug 440277 and Bug 443685.

These were resolved in the 3.1.0 release, which should be a part of the Eclipse Luna SR1 (4.4.1) update site. You most likely have the version of the Gcov Plugin shipped in the 3.0.0 release.

You could update to using Eclipse Luna SR1, and when you install the Gcov Plugin from there, it should resolve the issue. Alternatively, you could try just updating the Gcov Plugin for your current Eclipse Luna (4.4.0) using the update site, http://download.eclipse.org/linuxtools/update-3.1 .

Hope this helps.

I've updated gcov integration from http://download.eclipse.org/linuxtools/update-3.1 but there were new errors so I've installed SR1 and it works in simple project.
but...

Program runs is still 0.

And when I imported a C file with option Project->import->File System->(choose file from other workspace)->(choose create links in workspace; create virtual folders, create link locations relative to workspace_loc) code is not colored again.
Program runs is still 0 as it was without imported file.
File that is not imported is colored as it was.

When I double click on file name in gcov tab proper imported file opens but it's not colored.

So I think I found new bug Wink Is there a way to import file with creating a link from file system so gcov would work?
