Building Kcov
-------------
You need development headers and libraries for libglib, libdwarf and libelf
to build kcov.
Create an empty build dir and do the following steps:
# cmake <path/to/kcov/source/directory> <options>
# make
# make install
Useful options include -DCMAKE_INSTALL_PREFIX=<path> (installation prefix),
-DCMAKE_BUILD_TYPE=<type> and -DCMAKE_C_FLAGS=<CFLAGS>.
Basic example:
--------------
cd /path/to/kcov-source
mkdir build
cd build
cmake ..
make
make install
More advanced an example:
-------------------------
cd /path/to/kcov-source
mkdir build
cd build
cmake \
-DCMAKE_C_FLAGS:STRING="-O3 -march=i686" \
-DCMAKE_BUILD_TYPE=Release \
-DCMAKE_INSTALL_PREFIX=/usr \
..
make -j2 || exit 1
make install DESTDIR=/tmp/kcov-build || exit 1
-----------------------
For further information look for cmake documentation:
http://www.cmake.org/cmake/help/cmake-2-8-docs.html.
Troubleshooting
----------------
If you have libelf and libdwarf installed, but cmake fails to find them.
Add path to the header files to the CPATH variable and path to libraries to
LIBRARY_PATH variable and then run cmake again.
Here is an example:
-----------------------
export CPATH=$CPATH:/opt/libelf-dir/include/:/opt/libdwarf-dir/include/
export LIBRARY_PATH=$LIBRARY_PATH:/opt/libelf-dir/lib/:/opt/libdwarf-dir/lib/
cd kcov
cmake .
make
-----------------------
