colcon build std:error #57

Closed AlessioMosca closed 1 year ago

AlessioMosca commented 1 year ago

Hi there,

I am following the instruction on how to compile the pkg by colcon build: colcon build --cmake-args -DCMAKE_BUILD_TYPE=Release --symlink-install

and get the following output: 5 packages had stderr output: ethercat_driver ethercat_generic_cia402_drive ethercat_generic_slave ethercat_interface ethercat_plugins

However, after I get the error, if I reuse the previous command I am able to compile without errors.

Any suggestion ? Can be a dependency problem ?

Bets regards Alessio

Hi Alessio,

even though I'm not an expert I use colcon sometimes to build packages. I experience that kind of output very often. It does not mean that your build process failed. If that would be the case the output would be something like: 

Summary: x package(s) finished [time]
  x package(s) failed: package_xy, ...
  ...

For me personal the output you got never caused any problems with using the built packages. I think the output can also be related to warnings and information the packages provide via command line during build. Anyways if you want to see more clearly what happens I think you can try something like:

colcon build --event-handlers console_direct+

This should monitor all your build output in realtime.

Best regards
