             Bug #: 51807
           Summary: Fail to generate .gcno file when use libtool to
                    compile la library
    Classification: Unclassified
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: critical
          Priority: P3
         Component: gcov-profile
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: beanflowe...@gmail.com


1.The project need to use libtool to compile la files.
2.Add LIBS+=" -lgcov" in configure
3.configure CFLAGS="-g -Wall -Werror -Wno-unknown-pragmas -fprofile-arcs
-ftest-coverage" \
             CXXFLAGS="-g -Wall -Werror -Wno-unknown-pragmas -fprofile-arcs
-ftest-coverage" \
             --enable-unit-tests \
             --enable-libcurl \
             --disable-shared \
             --enable-developer-mode \

4.make
5.Check the la related cpp files ant gcov didn't generate .gcno file.

Is there any work around to resolve this issue? or if it needs to add
additional parameter.
