I am getting the following warning when attempting to compile a program that includes point_types.h

/opt/ros/groovy/include/pcl-1.6/pcl/point_types.h:56:0: warning: ignoring #pragma warning  [-Wunknown-pragmas]

The warning does not interfere with the build. However, so many of my files include point_types.h, that the build log gets polluted by multiple warnings. Is there any way to turn them off?

I'm using Ubuntu 12.10 and ros-groovy freshly installed from binaries.

Thanks.

I believe this is taken care of in later releases of pcl. For anyone who wants to suppress the warnings while compiling against pcl-1.6, this should do the trick:

rosbuild_add_compile_flags([name-of-target] '-Wno-unknown-pragmas')

Looks like that statement is trying to suppress some warnings, apparently without success:

// We're doing a lot of black magic with Boost here, so disable warnings in Maintainer mode, as we will never
// be able to fix them anyway
#pragma warning(disable: 4201)

I recommend opening a defect ticket.

Where would this defect be filed? I assume PCL upstream has that already fixed, so it's affecting the released PCL in groovy, which should be fixed with an updated release.

Maintenance on combined ROS and PCL issues confuses me. I suggest opening a ticket on pointclouds.org to get it fixed in the 1.6 release. Or, ask on the pcl-users mailing list.
