The 'issue' does not really seem to be getting the data at this point.
If I read the man pages of gcov/lcov correctly, it could be as easy as
something like this :



./configure --enable-debug --with-system-libcmis=no
--with-system-saxon=no --with-system-libs

LDFLAGS+='-lgcov' CFLAGS+='-fprofile-arcs -ftest-coverage'
CXXFLAGS+='-fprofile-arcs -ftest-coverage' CPPFLAGS+='-fprofile-arcs
-ftest-coverage' make

lcov --base-directory /usr/local/src/libreoffice --capture --initial
--directory /usr/local/src/libreoffice --output-file
libreoffice_base.info

make check

lcov --base-directory /usr/local/src/libreoffice --capture --directory
/usr/local/src/libreoffice --output-file libreoffice_test.info

lcov --add-tracefile libreoffice_base.info --add-tracefile
libreoffice_test.info --output-file libreoffice_total.info

genhtml --demangle-cpp libreoffice_total.info --frames --show-details
--legend --output-directory=/tmp/libreoffice-lcov



But the 'problem' im currently running into, is that LibreOffice wont
build when I specify LDFLAGS/CFLAGS/CXXFLAGS as mentioned above.
