Build fails on msvc (error w/ LINK)

[tbraun96]

Using rust x86_64-pc-windows-msvc 1.42 nightly

After cloning vanilla zk-paillier, and then trying to run a test in correct_key.rs, I get this error:

error: linking with `link.exe` failed: exit code: 1181

  = note: LINK : fatal error LNK1181: cannot open input file 'gmp.lib'

I've tried cloning rust-gmp, and then linking the subcrait's rust-gmp dependency towards the cloned/local rust-gmp, but the error persisted. At this point, I'm not sure if the error is on my side, or somewhere else

Hi @tbraun96 !

1. you need to install gmp on your machine first : https://gmplib.org
2. be aware that the code is tested on linux and iOS mainly (for example, both come with gmp installed). It should work well on windows but might require a bit of extra work (as you are now experiencing)

Please let me know if you have further questions

[tbraun96]

Thanks for the zippy response! Since you don't know if it works on windows, i'll let you know how it goes!

[tbraun96]

The solution does not appear to be trivial on windows. Compiling GMP on mingw_x64 works, however the output is not gmp.lib, but libgmp.a. Changing the name to gmp.lib and adding that to that path allows cargo to pick it up and read it, but then there are numerous errors relating to not finding the functions. This is non-trivial
