             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: unassigned@gcc.gnu.org
        ReportedBy: beanflowersh@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.

E.g.:
The frame of my project as below:
Dir1: 1.cpp 2.cpp 3.cpp
After compiled(add -fprofile-arcs -ftest-coverage), the files in the Dir1 as
below:
1.cpp 1.o 1.gcno
2.cpp 2.o 2.lo
3.cpp 3.o 3.lo
.libc/***.a ***.la

But there isn't the gcno files to be generated for 2.cpp and 3.cpp and I cannot
get the code coverage data for 2.cpp and 3.cpp.

This is not a bug in GCC but a bug in either libtool/automake or your
makefiles.

Thanks your advice, will check libtool.
