chaquopy package build Error: make[1]: *** [../Makefile.tail:40: libs] Error 127

Question

I wanted to use a newer version of numpy with chaquopy, that is not prebuild in the official repository, so i tried to buil it myself using the chaquopy package build tool. Because numpy relies on chaquopy-openblas i tried to build that first, however i get this error message:

make[1]: /home/default/Coding/chaquopy/server/pypi/packages/chaquopy-openblas/build/0.2.20/py3-none-android_21_armeabi_v7a/wrappers/armv7a-linux-androideabi21-ar: No such file or directory
make[1]: *** [../Makefile.tail:40: libs] Error 127

Answer 1

You don't need to build chaquopy-openblas, or any other host requirement from the meta.yaml file. Just download a pre-built copy from the public repository into your dist directory.

For more details, see the scikit-learn example in the README.
