Bug 608330 – dev-ros/camera_calibration_parsers required more precise python3 version specification in CMakeLists.txt

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description m.manico 2017-02-05 14:09:08 UTC]

Emerging dev-ros/camera_calibration_parsers will fail because

"  Could not find the following Boost libraries:

          boost_python3
"

The issue here is, that cmake can not match 'boost_python3' to '/usr/lib64/libboost_python-3.4.so'

The offending line in the packages source code is here:
https://github.com/ros-perception/image_common/blob/hydro-devel/camera_calibration_parsers/CMakeLists.txt#L10
(hydro-devel is probably not the correct version in this case, but the issue is the same regardless)

Workaround:
Correcting the above mentioned line to look for "python-3.4" (or whatever python 3 version you're using on your gentoo install) will allow successful emerging of the package. For a temporary fix use the following commands (as root):

ebuild /usr/portage/dev-ros/camera_calibration_parsers/camera_calibration_parsers-1.11.12.ebuild unpack

cd /var/tmp/portage/dev-ros/camera_calibration_parsers-1.11.12/work/image_common-1.11.12/camera_calibration_parsers

modify CMakeLists.txt at line 10 to use "python-3.4" instead of "python3"

ebuild /usr/portage/dev-ros/camera_calibration_parsers/camera_calibration_parsers-1.11.12.ebuild merge

I did not test if further modifications are required to successfully run the package.
