Build Fails ( ROS not sourced?)

[SimeonOA]

I am building a DockerFile for a project that depends on r2r.

I am using ros2 and have made sure to source my ros2 installation before building my application.

I keep having the following error during cargo build:

error: failed to run custom build command for `r2r_rcl v0.3.4`

Caused by:
  process didn't exit successfully: `/gdp-router/target/debug/build/r2r_rcl-70fc35e866c7fffb/build-script-build` (exit status: 101)

I have tried both rolling and humble and keep having this error.

Is there something I am missing or should be doing?

Thank you

Here is the error when I run with 'RUST_BACKTRACE=1':

You get this error when AMENT_PREFIX_PATH is not set in your environment. It should be set when sourcing your ros installation. To illustrate:

echo $AMENT_PREFIX_PATH
[empty - cargo build would fail]
. /opt/ros/humble/install/setup.bash
echo $AMENT_PREFIX_PATH
[stuff here - now your crate will build hopefully]

As a first step, can you verify manually that AMENT_PREFIX_PATH does get set when sourcing ros?
