Hey there, from today I cannot build anymore my custom msgs package. Anyone of you had such an error before:

catkin build ball_tracking_msgs

/bin/sh: 1: Syntax error: "(" unexpected
make[2]: *** [CMakeFiles/_ball_tracking_msgs_generate_messages_check_deps_BallState] Error 2
make[1]: *** [CMakeFiles/_ball_tracking_msgs_generate_messages_check_deps_BallState.dir/all] Error 2
make[1]: *** Waiting for unfinished jobs....
make: *** [all] Error 2

I had this error never before.... and on other machines my packages builds.... I installed blender today like this:

sudo apt-get update && sudo apt-get install python-software-properties
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:thomas-schiex/blender
sudo apt update && sudo apt install blender

Is the above blender installation responsible for my errors?

cmake_minimum_required(VERSION 2.8.3)

set(CMAKE_CXX_FLAGS "-std=c++11 ${CMAKE_CXX_FLAGS}")

find_package(catkin REQUIRED COMPONENTS roscpp actionlib_msgs actionlib message_generation std_msgs geometry_msgs)

Have you tried deleting your build and devel folders already (ie: catkin clean -y)? Does the same thing happen with catkin_make? And what is the contents of BallState.msg and your CMakeLists.txt?

yeah I did catkin clean -y see updates above.

I don't see anything obviously wrong.

Could you try on a clean install (ie: in a Docker container)? That way we could exclude local configuration being incorrect.

/bin/sh: 1: Syntax error: "(" unexpected

This suggests that some script either contains an error, the wrong interpreter ..

.. is being used or sh is being used for something which is not even a shell script.

Perhaps running the build in verbose mode can show the command line that is being executed at that point.

I just reinstalled ros-kinetic.... but have still the same error. I cannot build any code with messages anymore and have no clue why..... -> is this a python issue?

Have you already tried with catkin_make like I suggested earlier?

And a verbose build I believe is with VERBOSE=1 catkin_make -j1.

And please copy-paste a bit more of the output, typically problems show up quite a bit earlier than the exact line the (last) msg is printed.

Please clean your workspace before running the catkin_make command.

I just reinstalled ros-kinetic....

that is not a clean install btw. A clean install would be a clean ubuntu, but let's not do that. A docker container would be easier.

is this a python issue?

that could be.

Ok i just did this the verbose catkin make see above. (of course i cleaned before), I never worked with docker is it significantly faster than using ros in a virtual box? Just tried a clean install in a virtual machine and all works fine.....
