# Build a ROS Package - Method A

<note important>This needs to be confirmed, but it should work...</note>

When you need to build a separate package for ROS, instead of going throught all the steps like in the installation process, this should work

    mkdir -p temp_dir/src
    cd temp_dir/src
    # Here, put your package_folder
    cd ../
    # Maybe you can try this to resolve the dependencies, but I'm reaaaaally not sure 'bout that...
    #rosdep install --from-paths src --ignore-src --rosdistro hydro -y -r --os=debian:wheezy
    sudo /opt/ros/hydro/env.sh catkin_make_isolated -DBUILD_BINARY_PACKAGE=ON -DCMAKE_INSTALL_PREFIX=/opt/ros/hydro -DCMAKE_INSTALL_LIBDIR=lib --install --merge --install-space /opt/ros/hydro

Aaaannd, that's it.

# Build a ROS Package - Method B
This one doesn't directly rely on catkin, it doesn't manage dependencies though...

    mkdir yourpackage
    git clone --branch release/hydro/@package_name@/@package_branch@ @git_repository@ @package_name@
    mkdir build
    cd build
    cmake ../@package_name@ -DSETUPTOOLS_DEB_LAYOUT=OFF -DCATKIN_BUILD_BINARY_PACKAGE=ON -DCMAKE_INSTALL_PREFIX=/opt/ros/hydro -DCMAKE_INSTALL_LIBDIR=lib 
    make
    sudo make install

This method comes from the Archlinux PKGBUILDs, it works on Debian like this. There should be a way to checkinstall make install... and then we could (fully) package ROS for Debian in an easy, kinda automatic way...
