title: How to use lcov in cross compile environment.?
body: <p>I'm doing unit testing for device drivers for that i need to use gcov and lcov tools to generate reports.I compiled my code in native machine and the .gcno files are generated perfectly.Then i executed my output file in a arm based board and the gcda files also generated correctly.Then i have taken those files to my native and i generated .gcov files.</p>
  
  <p>But when i use lcov to that files it is showing errors like "negative length in /usr/src/geninfo line no 2414".</p>
  
  <p>1.So,For this what i need to do.?.
  2.And one more question is I'm using "arm-none-gnueabi-" toolchain(2011.03) for this it has gcov seperately but lcov is not present in the executables.Is it possible to use lcov.?.If yes how to use.?..Thanks in advance.</p>
