If you have both .gcno and .gcda files available you can use geninfo to generate HTML reports.

First we will generate a .info file which will help us generating the html view for our coverage reports. To generate the .info file we use: 

geninfo "path for .gcda files" -b "path for the source files" -o ./coverage1.info

The -b option is for setting the base directory for geninfo to search for source files.

This will generate coverage1.info which can be used to generate a html based coverage report. To generate the html report we use: 

genhtml coverage1.info -o temp
