compiling the runtime for linux - cmake error

[alphydan]

Hello,

I'm following the instructions on #77
I've created the docker image, but when trying to run cmake .. as suggested from the new build_on_linux directory I get

root@d19bb3bddcc1:/src/build_on_linux# cmake ..

I see the CMakeLists.txt file in the /src/ directory. Should I copy it to the directories where it can't find it? Or is there something else I should try.

Thank you.

I believe you may have run git clone without the --recursive flag, as the openvdb and GLFW libraries are submodules. Re clone the PicoGK runtime library with the flag and restart the steps and you should be good to go.

@joshmelnykcroft, thank you for your suggestion. You were totally right.

For future reference, this is what I ran on Ubuntu 22.04:

sudo snap install docker
git clone --recursive git@github.com:leap71/PicoGKRuntime.git
cd PicoGKRuntime/Misc/
docker build -t picogk2 .
cd ..
sudo docker run -it --rm -v /home/donquijote/Documents/code/picoGK/PicoGKRuntime:/src picogk2:latest bash
mkdir build_on_linux
cd build_on_linux/
cmake ..
make

which has compiled the shared object library file /src/build_on_linux/lib/picogk.so inside the docker container.
