Catkin plugin: Python nodes require gcc/g++ too.
Metadata
Current evaluation
Merged as commit 2f0c8ba04: catkin plugin now stages gcc/g++ unconditionally at the start of the build (instead of only when roscpp is a dependency), fixing LP bug #1638317.
Resolution: closed resolved
Reason: PR #881 was merged into snapcraft as commit 2f0c8ba04. It fixes LP bug #1638317 by moving gcc/g++ staging to the start of the Catkin build rather than gating it on roscpp being in the dependency list, so pure-Python workspaces build correctly.

Issue body
This PR fixes LP: [#1638317](https://bugs.launchpad.net/snapcraft/+bug/1638317) by staging them at the beginning instead of doing so dependent upon whether `roscpp` is in the dependency list.

| #1638317 Catkin plugin doesn't build pure python workspaces | snapcraft (launchpad) | closed | Catkin plugin only staged g++ when roscpp was a dependency, breaking pure-Python ROS workspaces. Fixed by snapcore/snapcraft PR #881 (merged as 2f0c8ba04), staging gcc/g++ unconditionally; issue closed by maintainer ~kyrofa. | |
| #840 Catkin plugin: build with in-snap python. | snapcraft | merged | Merged #840 as 7f9fa3ac1, fixing LP #1628990 by using in-snap Python during Catkin builds and adding gcc, libc-dev, and make as build packages. | |
| #1070 catkin plugin: don't stage compilers. | snapcraft | merged | Merged PR #1070 as commit ea8736af4, moving required Catkin compilers to an alternate work area so they are available during builds but excluded from final snaps; fixes LP #1658828. | |
| #1658828 Catkin plugin stages compilers | snapcraft (launchpad) | closed | Catkin no longer stages compilers: snapcore/snapcraft#1070 (ea8736af4) moved them to an alternate work area, keeping compiler bloat out of ROS snaps. | |
| #2545 catkin plugin: use build-packages for compilers | snapcraft | merged | Merged PR #2545 in commit ddb2d2627, replacing Catkin's side-loaded compiler workaround with required build-packages and fixing LP: #1827148 rebuild failures. | |
| #1130 catkin plugin: produce build-ready staging area. | snapcraft | merged | Merged PR #1130 (commit e34b7ab19) makes the Catkin plugin rewrite ROS-specific paths after building, creating a staging area reusable by later parts and fixing LP #1663385. |
