Dear ros users,
I have a problem with rosboost-cfg. Here is the situation I encountered.
I'm using MontaVista Linux and had already installed boost at /usr/local
which is 1.36.0 and was used intensively by existing softwares. I have
installed cturtle_base using rosinstall. The ros requires boost which is
greater than or equal to 1.37.0. So I've installed boost 1.40.0 at
/opt/boost and set ROS_BOOST_ROOT to /opt/boost. I've managed to
successfully build 38 packages out of ros. Everything was going smoothly
upto this.
I was interested in pluginlib so I built it and tried pluginlib_tutorials
at
http://www.ros.org/wiki/pluginlib/Tutorials/Writing%20and%20Using%20a%20Simple%20Plugin
I tried to execute polygon_loader and got a seg fault.I tried to trace back
to a root cause using gdb and the core file. When loading executable, gdb
prints out these messages for loading shared libraries

As you can see in bold & blue text, rosconsole was compiled using
/usr/local/include/boost header but linked against /opt/boost/lib.
So I suspected that there was something wrong with rosboost-cfg.
When I executed 'rosboost-cfg --cflags', I got nothing but -L/opt/boost/lib
-Wl,-rpath,/opt/boost/lib -lboost_regex for 'rosboost-cfg --lflags regex.'
I analyzed rosboost_cfg.py source and found that Version.__init__() has
strange code segment about is_system_install property as follows
self.is_system_install = os.path.split(self.include_dir)[0] == self.root
For my environment, self.include_dir == /opt/boost/include and self.root ==
os.path.split(self.include_dir)[0] == /opt/boost.
And the include_dirs() subroutine returns value for --cflags option as
follows
def include_dirs(ver, prefix = ''):
if (*ver.is_system_install* or no_L_or_I):
return ""
return " %s%s"%(prefix, ver.include_dir)
I don't know what is_system_install exactly means but for my environment, I
definitely need value of -L/opt/boost/include for --cflags. So I modified
the code as follows
def include_dirs(ver, prefix = ''):
if (no_L_or_I):
return ""
return " %s%s"%(prefix, ver.include_dir)
After this modification, I managed to execute polygon_loader successfully. I
think this modification works only for me.
Please, fix this problem.
TIA
