Error building rosgraph_msgs

[tylerjw]

I am trying to follow the instructions for building ros with tsan and I'm running into what seems like a really odd build error:

--- stderr: rosgraph_msgs

Bug report

Required Info:

• Operating System:
  • Ubuntu 20.04

Steps to reproduce issue

colcon build --build-base=build-tsan --install-base=install-tsan \
    --cmake-args -DOSRF_TESTING_TOOLS_CPP_DISABLE_MEMORY_TOOLS=ON \
                 -DINSTALL_EXAMPLES=OFF -DSECURITY=ON --no-warn-unused-cli \
                 -DCMAKE_BUILD_TYPE=Debug \
    --mixin tsan ccache \
    --symlink-install

Expected behavior

No build error.

Actual behavior

If I cd into that directory it looks like it's created a symlink to a directory that does not exist:

> cd /home/tyler/code/rolling/ws_moveit_source/install-tsan/rosidl_typesupport_c/lib/rosidl_typesupport_c/
> ll

lrwxrwxrwx 1 tyler tyler 110 Nov 26 13:02 rosidl_typesupport_c -> /home/tyler/code/rolling/ws_moveit_source/src/rosidl_typesupport/rosidl_typesupport_c/bin/rosidl_typesupport_c

That is pretty odd, I agree. What happens if you build without --symlink-install?

[tylerjw]

Thank you for the response. I feel dumb for not trying that. I just did and it makes it past the rosgraph_msgs package. I'm happy to assign this to the "symlink-install feature is not ready yet" bucket. I have had problems with it before and this time I mostly blindly copy-pasted from that guide and somehow didn't notice it (even when the error seemed to be an odd symlink).

[clalancette]

Generally --symlink-install should work, so we should probably file an issue over at colcon instead.

I'm going to close this out, as this seems to be a problem in colcon and we have an issue filed over there. Feel free to reopen if this is in error.
