Hi,
I would like to generate gcov/lcov report by using LTP test source.
1. ./configure CFLAGS="-Wall -fprofile-arcs -ftest-coverage -g"
LDFLAGS="-lgcov -fprofile-arcs"
2. make all
3. make install (easy and serve the purpose)
4. ./runltp -f syscalls (obvious nothing happens, because i am running it
from ltp dir)
gcov need source and binary should be present in the same location to
generate final gcov output file sourcefile.c.gcov
I am looking for (three years) old style of running tests in ltp ( like as
runltp do not look for /ltp/bin or testcase/bin or /opt/bin for test
binaries, just go to each testcase/kernel/syscall/each-dir-and-run). Not
ready to go back and use old ltp version, instead i am looking a way to run
test from its source directory which will benefits gcov/lcov to generate
coverage report.
Manual execution of gcov:
