Issue with running biodynamo after a successful build

[YBelikov]

Hello!

I tried following developer's guide to run biodynamo on the provided demos. With your help I was able to resolve build issues on macOS, however, I am currently struggling with actually running biodynamo. After the build I got a build/bin subdir with a bunch of executables such as bdm, but an attempt to run it fails with the following error:

File "/Users/ybelikov/Dev/biodynamo/build/bin/./bdm", line 16, in <module> from main import Main File "/Users/ybelikov/Dev/biodynamo/build/bin/main.py", line 19, in <module> from demo_command import DemoCommand File "/Users/ybelikov/Dev/biodynamo/build/bin/demo_command.py", line 23, in <module> DEMO_DIR = os.path.join(os.environ["BDMSYS"], "demo") ~~~~~~~~~~^^^^^^^^^^ File "<frozen os>", line 709, in __getitem__ KeyError: 'BDMSYS'

Can you suggest how can I setup a BDMSYS env variable and where it should point?

Hi @YBelikov!
You’re hitting this error because the BioDynaMo environment hasn’t been initialized. The bdm CLI expects the BDMSYS environment variable to be set, which normally happens when you source the setup script.

Please try to run:

source <path-to-biodynamo-installation>/bin/thisbdm.sh
