And the problem doesn't present on Ubuntu, where the libtinyxml-dev package installs tinyxml.h with TIXML_USE_STL #defined. That's why I went for the source rosdep approach for tinyxml on OSX. I'd prefer to use tinyxml (and every other library) from a standard installation, but I couldn't see a good way to make the macports installation of it work. brian. > On Fri, Sep 2, 2011 at 9:49 AM, Brian Gerkey > wrote: >> >> hi Kevin, >> >> On Fri, Sep 2, 2011 at 8:06 AM, Kevin Walchko >> wrote: >> > I am having problems compiling nodelet. >> > ROS electric, OSX Lion 10.7 using macports and default compiler >> > I had to define STL use in loader.cpp, otherwise the macports of tinyXML >> > didn't make certain class members available: >> > #define TIXML_USE_STL >> > is there a way to define this in CMakeLists.txt? >> >> Did the tinyxml source rosdep not work for you?  `rosdep install >> nodelet` should build and install an appropriately configured version >> of tinyxml from https://kforge.ros.org/rosrelease/sourcedeps/tinyxml. >> I wrote that because I was having the same trouble you are (and more, >> as I recall) with using the macports version of tinyxml.
