Summary from the ROSCon cross-compilation Meetup:
Current issues faced by users cross compiling ROS 2:
-
lack of Python or third party library support in the instructions currently hosted on the ros2-for-arm organization.
-
lack of instructions + sysroot for Android compilation makes it hard to compile high level packages and demos
Suggestions:
-
Provide a single place for aggregating cross-compilation instructions
-
Community members can modify the content to add instructions for their platform/architecture.
-
Community members will also be in charge of testing / updating the instructions they provided if necessary.
-
Possible location: a page on the ros2 wiki with section for each platform/architecture.
-
Leveraging existing toolchains and infrastructure (@esteve suggested polly) could reduce maintenance effort and provide better experience for users.
-
contributors can elect to provide a sysroot to allow installing and linking against target libraries more easily.
