[ros-users] openrave fails to build with linker error

[Antons Rebguns]

Hi Rosen,

It looks like it tries to find gfortranbegin when generating some octave
bindings:

Scanning dependencies of target orcreate_octave
make[3]: Leaving directory
`/home/robotlab/ros/wg-ros-pkg-unreleased/stacks/openrave_planning/openrave/openrave_svn/build'
make[3]: Entering directory
`/home/robotlab/ros/wg-ros-pkg-unreleased/stacks/openrave_planning/openrave/openrave_svn/build'
[ 89%] Generating orcreate.mex
/usr/bin/ld: cannot find -lgfortranbegin

There were new system dependencies for rosoct (octave3.0-headers package
which bring the whole fortran compiler). I just tried removing gfortran
package and OpenRAVE compiled just fine. I guess it just skips
that orcreate.mex generation if it doesn't find the right dependencies.
