Unable to install python-casacore

[GhidoniR]

I have a MacBook Air with chip Apple M1 and MacOS Ventura 13.4. I also have the python version 3.11.5.

When I try to install python-casacore with pip I get the error

fatal error: 'boost/python.hpp' file not found
      #include <boost/python.hpp>
               ^~~~~~~~~~~~~~~~~~
      1 error generated.
      error: command '/usr/bin/clang' failed with exit code 1

If I try to install from the source repository I get:

fatal error: 'casacore/python/Converters/PycBasicData.h' file not found
#include <casacore/python/Converters/PycBasicData.h>
         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.
error: command '/usr/bin/clang' failed with exit code 1

How can I solve this?

We are currently not able to create binary wheels for MacOS Mx processors, unfortunately. You therefore need to build python-casacore from source. For that you need to install at least the following:

• Boost.Python, including development files (header files)
• Casacore, including development files (header files)

I'm not an Apple expert, but if I recall correctly people have successfully built python-casacore using Brew. Hope this helps.

Thank you so much. I have installed both boost and casacore but now I get this error:

clang++ -bundle -undefined dynamic_lookup -Wl,-rpath,/Users/ghidoni/anaconda3/lib -L/Users/ghidoni/anaconda3/lib -Wl,-rpath,/Users/ghidoni/anaconda3/lib -L/Users/ghidoni/anaconda3/lib -std=c++11 build/temp.macosx-11.1-arm64-cpython-311/src/fit.o build/temp.macosx-11.1-arm64-cpython-311/src/fitting.o -L/usr/local/lib -L/opt/homebrew/lib -lcasa_scimath -lcasa_scimath_f -lboost_python311 -lcasa_python3 -o build/lib.macosx-11.1-arm64-cpython-311/casacore/fitting/_fitting.cpython-311-darwin.so

ld: library not found for -lcasa_python3
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command '/usr/bin/clang++' failed with exit code 1

Any idea what cause this? I am installing from the repository, not directly with pip or brew

Maybe you should use brew. Like I said, I'm not an Apple expert. The error message means that the linker cannot find the casa_python3 library. It probably means that brew puts this in a directory that is not search by the linker by default. You could try to add -L<path/to/casa_python3-library> to the link command, where you need to fill in the correct path of course.
