Python is already installed

Did you install python-dev package ?

I've tried to run 2.4.0-beta.5
And I've got many security alerts for each "executable" (each plugin, each script interpreter,... each .so (script wrapper).
I have to authorize them all manually (one by one....)

OK after having disabled apple security by running this command into yadoms folder:
xattr -r -d com.apple.quarantine .

I have the same error as @oben01

I've checked the real error and it seems a "rpath" error. At build time (into docker) the scriptWrapper are linked with python libs located at /opt/local/Library/Frameworks/Python.framework/Versions/2.7/Python. And at runtime, it search for with library at the same place.
Have to review cmake settings about that. (its a common problem with dynamic linking)

I've created an issue on cross toolchain repository
tpoechtrager/osxcross#247

[jano42]

Fied by installing python2 and python3 using macports

sudo port install python27 python38

In fact the build system is too much linked with a specific python version and path.

Create new issue to solve this one
