[LCOV] (http://ltp.sourceforge.net/coverage/lcov.php) is a graphical front-end for GCC's coverage testing tool gcov. It collects gcov data for multiple source files and creates HTML pages containing the source code annotated with coverage information. It also adds overview pages for easy navigation within the file structure. LCOV supports statement, function and branch coverage measurement.

0. Install Perl if not installed. For example to C:\Perl

1. Open Windows Command Processor and run to create association (do not forget to change path to perl.exe)

   assoc .perl=Perl.File
   ftype Perl.File=C:\Perl\bin\perl.exe "%1" %* 
   

2. Define correct path of GCOV executable in geninfo.perl:

   our $gcov_tool = "C:\\CORRECT_PATH_TO\\gcov.exe";
   

3. Define correct path of Perl executable in lcov.bat:

   set perl=C:\CORRECT_PATH_TO\Perl.exe
   

1. Compile your project to support GCOV. As a result *.gcno files will be created.

2. Run your binaries and *.gcda files will be created. You can place them to the same dir with *.gcno.

3. Go to a project root dir where *.gcda and *.gcno files placed.

4. Run lcov.bat

   d:\project> d:\lcov\lcov.bat
   Creating gcov\lcov.info ...
   Capturing coverage data from .
   d:\lcov/geninfo.perl . --output-filename gcov/lcov.info --base-directory .Found gcov version: 4.4.2
   Scanning . for .gcda files ...
   

5. After execution gcov\html dir will be created with html reports for current project.
