Ros1_bridge not mapping custom fields with different names even with yaml file

edit

I am using the bridge and all of my messages are correctly mapped except for 1 where I had to change the name from the ros1 version of the message (ros2 does not allow capital letters).

Here is the ros2 version

float32 velocity
float32 current
uint8 command_flag
float32 r_jnt

Here is the ros1 version

float32 velocity
float32 current
uint8 commandFlag
float32 R_jnt

Here is my yaml file

-
  ros1_package_name: 'edo_core_msgs'
  ros1_msg_name: 'JointState'
  ros2_package_name: 'edo_core_msgs'
  ros2_msg_name: 'JointState'
  fields_1_to_2: 
    R_jnt: 'r_jnt'
    commandFlag: 'command_flag'
    current: 'current'
    position: 'position'
    velocity: 'velocity'

Here is the CMakeLists.txt (only the related part)

rosidl_generate_interfaces(${PROJECT_NAME}

  ${msg_files}
  ${srv_files}

 )

 install(
  FILES mapping.yaml
  DESTINATION share/${PROJECT_NAME})


 ament_export_dependencies(rosidl_default_runtime)

ament_package()

Package.xml

  <export>
    <ros1_bridge mapping_rules="mapping.yaml"/> 
    <build_type>ament_cmake</build_type>

  </export>

My file structure looks like this

.
├─ ros1_msgs_ws
│  └─ src
│     └─ bridge_msgs
│        └─ msg
│           └─ JointCommand.msg

│        └─ # YAML file if your custom interfaces have non-matching names
└─ bridge_ws

I am using Eloquent built from debian and am bridging to melodic. Im using ubuntu 18.04. Ive followed all the instructions for building very closely and have reproduced the error on mulptiple computers. The bridge builds and includes all my messages except this one. I am now trying to build eloquent from source.

One last thing tht may be related or not. I get error messages when I build the bridge in the format of this:

  Some of these libraries may not be found correctly.
