Build error on win 10

Win10 and .NET Core 3.1 is installed

Anybody knows what's going on and how to fix this? Thanks

Hi @michaelchi08,

I am also facing the same error. rcldotnet_common fails to be built without any explicit error log. Have you resolved the issue?

[michaelchi08]

Hi @berkayalpcakal , no unfortunately not yet 😞

Hi again,

I was able to build this repository in a ros2 workspace on my Ubuntu 18.04 machine. Then I wanted to build these packages in a ros2 workspace on my Win 10 machine. But 'rcldotnet_common' does not build for some reasons, and gives the aforementioned build output.

Then I decided to follow the way as described in here (using Linux kernel based docker on my Win 10 machine). Finally I successfully built the ros2dotnet on Win 10.

Hi, thanks for letting me know. I'll give it a try. it'll be nice if we could run this natively though. Do yo know if it's possible to run just this in docker and the all other ros2 nodes natively on windows?

Hello. I tried building ros2_dotnet on my windows 10 system today (with Foxy release of ROS2 installed), and I have been seeing the same errors previously mentioned here.

I decided to run the colcon build command with an extra flag (colcon build --merge-install --event-handlers console_cohesion+) and I started seeing some new output in error messaging:

C:\ros2-windows\include\rcl\rcl/event_callback.h(18,10): fatal error C1083: Cannot open include file: 'rmw/event_callback_type.h': No such file or directory (compiling source file C:\Users\Jack Hate\Desktop\GetStartedApp\ros2_dotnet_ws\src\ros2_dotnet\ros2_dotnet\rcldotnet\rcldotnet_node.c) [C:\Users\Jack Hate\Desktop\GetStartedApp\ros2_dotnet_ws\build\rcldotnet\rcldotnet_native.vcxproj]

So then I poked around the install location for ROS2 and I noticed that event_callback_type.h does in fact exist but it's path is rmw\rmw\event_callback_type.h when starting from the include folder.

To verify this was the issue, I tried moving the event_callback_type.h file to the parent directory. Doing this still resulted in a build failure but with new error messages that appear to be syntax issues: C:\ros2-windows\include\rcl\rcl/subscription.h(59,1): error C2059: syntax error: '}'

See attached file for a larger snapshot of the build output. ros2_dotnet_build_output.txt

I am out of my depth in debugging this further, but maybe someone else can figure out what's going wrong from my findings.
