[LTP] LTP fails to build for Application Code Coverage

[LTP] LTP fails to build for Application Code Coverage

[Subrata Modak]

Hi Peter,

I was just trying to build LTP for finding itś own code coverage, but
with the GCC options mentioned in lcov/INSTALL, i get the following
build failure. Is there something i am missing:

# ./configure
# make CFLAGS=\ -fprofile-arcs\ -ftest-coverage\ -Wall

we already solved this issue via ST but I'll still post the result here 
for reference: to prevent this particular error, you'll need to also 
provide the additional linker option -coverage.

As not all ltp Makefile work well when specifying CFLAGS and LDFLAGS on 
the make command line, you'll need to specify those during the configure 
step, i.e.

./configure CFLAGS="-fprofile-arcs -ftest-coverage" LDFLAGS="-coverage"
make


Regards,
   Peter

    Correct. I updated INSTALL to explicitly state `do not define
CFLAGS, CPPFLAGS, etc' on the command line with make. People need to
either specify the right values to configure, and/or modify the values
in include/mk/config.mk (which gets produced by configure).
Thanks,
