Graph-tool: compile and connect to local CGAL library, in Linux? (no sudo)

[Ubuntu]

I have compiled CGAL locally:

/path/to/cgal/
    /lib/
        libCGAL_Core.so     libCGAL_Core.so.13.0.2  
        libCGAL_ImageIO.so.13      libCGAL.so     libCGAL.so.13.0.2
        libCGAL_Core.so.13  libCGAL_ImageIO.so      
        libCGAL_ImageIO.so.13.0.2  libCGAL.so.13
    /include/
        /CGAL/
            version.h compiler_config.h

And I have managed to satisfy all of the graph-tool requirements except cgal (at least all of the requirements checked up to cgal):

./configure --with-boost=/path/to/boost --with-cgal=/path/to/cgal

And I get all successes up and until I get the following error message:

checking for __gmpz_init in -lgmp... yes
checking for __gmpz_init in -lgmp... (cached) yes
checking whether CGAL is available in /path/to/cgal... no
configure: error: CGAL library not found.

// the harshest part is that it seems to be searching in the correct
// directory.

I have tried specifying different points in the cgal build directory. The cgal compilation command I used was (from build directory):

cmake path/to/cgal_src_dir -DCMAKE_BUILD_TYPE=Release;

Next, I tried adding includes:

./configure --with-boost=$boost --with-cgal=path/to/cgal CPPFLAGS="-I path/to/cgal/include -I $HOME/.local/include" LDFLAGS="-L path/to/cgal/lib -L $HOME/.local/lib -Wl,-rpath=$HOME/.local/lib"

I will admit that I don't understand the -Wl,-rpath= part, I copied that from the graph-tool installation guide. The .local/lib folder contains the files for the other components, such as gmp, expat, sparsehash, etc.

Solution

This is not exact answer but as asked by OP will help in finishing installation, so please don't vote blindly.

To create debian package of libcgal open your CMakeList.txt and at the end of file add:

#--------------------------------------------------------------------
# Create debian files
#--------------------------------------------------------------------
if (UNIX AND NOT APPLE)
    SET(CPACK_GENERATOR "DEB")
    SET(CPACK_PACKAGE_NAME  "libcgal-all")
    SET(CPACK_PACKAGE_VERSION  "${CGAL_VERSION}")
    SET(CPACK_PACKAGE_DESCRIPTION_SUMMARY  "C++ library for computational geometry (development files)\n CGAL (Computational Geometry Algorithms Library) makes the most important of the solutions and methods developed in computational geometry available to users in industry and academia in a C++ library. The goal is to provide easy access to useful, reliable geometric algorithms.\n .\n This package contains the header files and static libraries for libCGAL.so, libCGAL_Core.so, and libCGAL_ImageIO.so. The  header files and static libraries for libCGAL_Qt4.so can be found in the package libcgal-qt4-dev.")
    SET(CPACK_PACKAGE_CONTACT "bordeo")
    SET(CPACK_DEBIAN_PACKAGE_DEPENDS  "libboost-dev, libboost-thread-dev, libboost-system-dev, libboost-program-options-dev, libgmp10-dev, libmpfr-dev, zlib1g-dev")
    SET(CPACK_DEBIAN_PACKAGE_REPLACES "libcgal10, libcgal-dev")
    INCLUDE(CPack)
endif()

In case you don't have any dependency remove whole line of SET(CPACK_DEBIAN_PACKAGE_DEPENDS "libcln6, libcln-dev, libreadline6, libreadline6-dev, flex, bison"), and change others as it seems fit.

Now go to the terminal and issue following commands in cgal directory

mkdir build
cd build
cmake-gui ..
# set CMAKE_INSTALL_PREFIX to `~/.local
cmake ..
make -j4
cpack ..

you will find your debian built. Extract or install the debian to ~/.local.

Once this is done go to graph tool directory and start the build like

./configure --prefix="/wherever"  --with-boost=/path/to/boost --with-cgal=~/.local
make -j4
make install

Hope this will solve your problem.
