Hello everyone,

I uncounted a problem when I was installing ROS from source.

I got the following error when I executed command:

--------------------------------------------

sudo ./src/catkin/bin/catkin_make_isolated --cmake-args -DBOOST_ROOT=/home/exbot/boost_1_44_0_gcc_4_4 -DBoost_NO_SYSTEM_PATHS=ON -DCMAKE_C_COMPILER=/usr/bin/gcc-4.4 -DCMAKE_CXX_COMPILER=/usr/bin/g++-4.4 

--------------------------------------------

I used my pre-built include/lib files of boost 1.44.  I have to use boost 1.44 in order to link against the same version of boost that is used in MATLAB R2012a.

Here is the error:

==> Processing catkin package: 'qt_gui_cpp'

<== Failed to process package 'qt_gui_cpp': 

  Command '/home/exbot/roscatkin_ws/devel_isolated/pluginlib/env.sh make -j4 -l4' returned non-zero exit status 2

Reproduce this error by running:

==> cd /home/exbot/roscatkin_ws/build_isolated/qt_gui_cpp && /home/exbot/roscatkin_ws/devel_isolated/pluginlib/env.sh make -j4 -l4

Command failed, exiting.

My system: Ubuntu 12.04

ROS: Hydro

Is there anyone who can help me fix this? Thanks in advance!

Sincerely yours,

Fei LIU
