Installation Troubleshooting

Flow Registration

⚠️ Missing LICENSE file

Expected repository to contain a LICENSE file.

NANSEN's automatic installer expects GitHub repositories to include a LICENSE file. Flow Registration currently does not match this layout.

Next step: Download or clone Flow Registration manually from https://github.com/FlowRegSuite/flow_registration and follow its installation instructions.

⚠️ Native MEX build failure

Error using mex
Undefined symbols for architecture arm64:
  "_mexCreateMexFunction", referenced from:
      <initial-undefines>
  "_mexDestroyMexFunction", referenced from:
      <initial-undefines>
  "_mexFunctionAdapter", referenced from:
      <initial-undefines>
ld: symbol(s) not found for architecture arm64
clang++: error: linker command failed with exit code 1 (use -v to see invocation)

Flow Registration was downloaded, but MATLAB could not compile its native MEX components.

Next step: See https://github.com/FlowRegSuite/flow_registration/issues/31
