Isn't it defined by default? Because i compiled bullet without modifying anything but when I try to compile gazebo it returns the attached error. Anyway now I successful compiled wxpropgrid but when I try to compile rviz it returns the following error: http://ros-users.122217.n3.nabble.com/file/n1838010/build_output.log build_output.log Maybe the problem is that py25-wxpython doesn't work with 64 bit? tfoote wrote: > > To compile bullet with double precision you need to define > > -DBT_USE_DOUBLE_PRECISION > > We also use > -DBT_EULER_DEFAULT_ZYX > > in our ROS build of bullet. > > See > https://code.ros.org/svn/ros-pkg/stacks/geometry/tags/geometry-1.2.0/bullet/Makefile.bulletand > https://code.ros.org/svn/ros-pkg/stacks/geometry/tags/geometry-1.2.0/bullet/CMakeLists.txt > > Tully > > > On Wed, Nov 3, 2010 at 8:30 AM, lucaghera wrote: > > -- View this message in context: http://ros-users.122217.n3.nabble.com/Gazebo-on-MAC-OS-10-6-tp1820916p1838010.html Sent from the ROS-Users mailing list archive at Nabble.com.
