Can't compile libflutter_engine.so

[volkrass]

I know is not related directly to you repository, but might be you have an advice for me.
I'm followed the steps from flutter from scratch article. I get nearly all my files in engine/src folder compiled. Build process stuck AT ../flutter/shell/platform/glfw/flutter_glfw.key_event_handler with ../../third_party/glfw/include/GLFW/glfw3.h:171:12: fatal error: 'GL/gl.h' file not found

In my /opt/vc/include folder copied form my Raspberry PI 3 there are only header files in EGL/GLES/GLES2. I don't have a /opt/vc/include/GL
Is there an option to use EGL or GLES instead? Or do I missing some packages on my Raspberry PI?
Thanks in advance.

You need to enable the Raspberry Pi GL support by doing sudo raspi-config navigate to Advanced, GL Driver and select Fake KMS (or Full KMS). The header files should then be in /usr/include and the OpenGL lib in /usr/lib/.

Then, as usual, rsync the raspberry pi root to your host-machine's cross-compilation sysroot.

For the embedder & engine to run, you need to disable the raspberry pi's GL support again (simply switch to Legacy in raspi-config) otherwise you'll get a "service already in use" message.

Thank you for your support. Sorry for doubling my question, but I read too late that you have created this repo. Therefore I thought it would be better to discuss technical details here.

Looks like I have fixed my problem. I installed following packages gtk3-dev, libglib2.0-dev and libgl1-mesa-dev on on my Rasp PI to solved my linker issues. Thanks for your support.
