ros_gz_bridge build fails "gmake Error 2"

[biagio-trimarchi]

Environment

• OS Version: Ubuntu 22.04
• Source or binary build? From source, branch "origin/humble".

Description

• Expected behavior: Compiling without issues
• Actual behavior: Build failed, I think due to "running out of memory"

Steps to reproduce

1. Download the source code from github and fork the "humble" branch
2. Build the package with "colcon build"

Output

can you try to run the colcon command with --parallel-workers 1

I think you are running out of memory

[biagio-trimarchi]

Hi, I tried and I got the same error.

[biagio-trimarchi]

It worked with "--parallel-workers 4", after closing tmux and any other program.

Still, I think the package should be made "lighter" to build.
