Link flag error

[hsu]

Some of the catkin added link flags in the package installed .pc files appears incorrect. For example, ros-groovy-console-bridge installs:

/opt/ros/groovy/lib/pkgconfig/console_bridge.pc

which contains a line:

Libs: -L/opt/ros/groovy/lib -lconsole_bridge -l/usr/lib/libboost_thread-mt.so -lpthread

But the libboost_thread_mt link flag is wrong, it should be

Libs: -L/opt/ros/groovy/lib -lconsole_bridge /usr/lib/libboost_thread-mt.so -lpthread

The extra -l triggers a compile error:

Linking CXX shared library libgazebo_sdf_interface.so
/usr/bin/ld: cannot find -l/usr/lib/libboost_thread-mt.so

It seems catkin_depends might be adding the extra boost library link flags incorrectly?

Please provide a description what you do to reproduce the failure.

[hsu]

checkout simulator_gazebo from trunk, edit gazebo/CMakelists.txt, modify the line:

set(USE_HG false)

to

set(USE_HG true)

then

rosmake gazebo

this will checkout gazebo into gazebo/build/gazebo-hg. When compile is finished, edit gazebo/build/gazebo-hg/cmake/SearchForStuff.cmake and modify line 268, change find_package to pkg_check_modules:

pkg_check_modules(console_bridge console_bridge)

Next,

rm -rf gazebo/build/gazebo-hg/build

then, re-compile, and you should be able to see the error.

rosmake gazebo
