Re: [Quantlib-users] Build quantlib wheel using Docker

[Luigi B. <lui...@gm...>]

Hello Alix,
    I'm not sure that `auditwheel repair` works outside the manylinux
images.  Personally I'm using the `quay.io/pypa/manylinux2010_x86_64` image
to build the QuantLib wheels on PyPI (used to be `
quay.io/pypa/manylinux1_x86_64`, but since the latest release we need a
C++11 compiler so I upgraded).  If you want to distribute to users on a
given Ubuntu version, I'd probably distribute both the wheel (unrepaired)
and the shared library.  If you want a self-contained wheel, another
possibility (which I have done on Mac OS, but not on Linux so I can't
guarantee it works) might be to run `configure` with `--disable-shared`, so
it only creates the static library.  This way, the library code would be
linked in the wrappers instead of being a dependency.

Hope this helps,
    Luigi
