Hi, I am not able to obtain the link flags and cflags for boost required for using 'making' one of my packages. Running *rosboost-cfg --libs regex* gives this error Traceback (most recent call last): File "/opt/ros/cturtle/ros/bin/rosboost-cfg", line 35, in rosboost_cfg.main() File "/opt/ros/cturtle/ros/tools/rosboost_cfg/src/rosboost_cfg/rosboost_cfg.py", line 359, in main output = lflags(ver, options.lflags.split(',')) File "/opt/ros/cturtle/ros/tools/rosboost_cfg/src/rosboost_cfg/rosboost_cfg.py", line 276, in lflags print >> s, lib_flags(ver, lib), File "/opt/ros/cturtle/ros/tools/rosboost_cfg/src/rosboost_cfg/rosboost_cfg.py", line 265, in lib_flags lib = find_lib(ver, name) File "/opt/ros/cturtle/ros/tools/rosboost_cfg/src/rosboost_cfg/rosboost_cfg.py", line 235, in find_lib raise BoostError('Could not locate library [%s]'%(name)) rosboost_cfg.rosboost_cfg.BoostError: 'Could not locate library [regex]' I am assuming that one of the environment variables are missing, but not sure which one.
