Feature request: add static linking option

[hombit]

It would be nice if the crate supports static linking with the GSL via a Cargo feature flag. The most of scientific crates with bindings provide such an option, e.g. ndarray-linalg, fftw, netcdf and hdf5

So basically doing that: https://github.com/rust-math/fftw/blob/master/fftw-sys/src/lib.rs#L13-L16? If so, feel free to send a PR. :)

[hombit]

I mean something like this:
https://github.com/rust-math/fftw/blob/master/fftw-sys/src/lib.rs#L3-L4
and this:
https://github.com/rust-math/fftw/tree/master/fftw-src

I thing it would require creating gsl-src crate which will be dedicated to hold sources for the current GSL release and compile it to a static library. While we have it we could add a feature to gsl and gsl-sys saying if we use statically compiled GSL.

Would you accept PR doing something like this?

[GuillaumeGomez]

Oh I see, then no. I don't want to embed the sources of the C library and handle its compilation myself.

[hombit]

Thank you for the answer

[hombit]

Sorry, I probably miss-understood you. Would it be acceptable to introduce a Cargo feature forcing static links against a locally installed static GSL?

[GuillaumeGomez]

If it doesn't need to run a C compiler to do so, then I'm fine with it.
