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:

Reproduce this error by running:

/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,
