How to fix "geninfo: ERROR path/to/i386.gcno : could not open file" relating to coverage using gcov

I my trying to do code coverage of gcc source code for a set of 2000 programs. I built compiler with --enable-coverage compiler option so it generates the coverage files upon compilation of a sample program.

Running the following command :

path/to/bin/lcov -c -d  path/to/*.gcda/files/ -o info.info

I am getting error as:

Capturing coverage data from .
Found gcov version: 6.3.0
Scanning . for .gcda files ...
Found 460 data files in .
Processing i386.gcda
geninfo: ERROR: build/gcc/i386.gcno: could not open file

I am unable to find anything on google for such problem?

Make sure your .gcda and .gcno files are in the same directory as gcov searches for .gcno files in the same location where .gcda files are.
