In C:\Users\Iain\.julia\GnuTLS\deps\bin there is a libgnutls-28.dll but that isn't on the alias list, testing adding that...

[IainNZ]

I added libnettle-4-7.dll for Nettle and libgnutls-28.dll for gnutls but still says it can't load it.

[IainNZ]

Ahh... hold on: provides(Binaries,URI("ftp://ftp.gnutls.org/gcrypt/gnutls/w32/gnutls-3.2.1-w32.zip"),gnutls,os = :Windows) so its trying to load 32-bit binaries?

[IainNZ]

I can't seem to find 64-bit binaries, but I'm not sure why it can't extract that folder anyway.

[mlubin]

There's a gnutls package available through WinRPM, but after installing it and modifying build.jl to search for libgnutls-28 both 32- and 64-bit julia crash when running using GnuTLS.

Error message for win32:

Win64 is silent when it crashes.

Any help here @ihnorton, @vtjnash?

[ihnorton]

Did you remove the win32 DLLs? Also, mind to post the modified build.jl in a gist?

[mlubin]

Yes, removed the old DLLs. Here's my modified build.jl: https://gist.github.com/mlubin/8500398

[ihnorton]

https://github.com/loladiro/GnuTLS.jl/pull/16 uses the caching mechanism (which in this case just means it crashes faster)

[ihnorton]

It works when julia is run as Administrator [edit: nevermind. no it doesn't]. Perhaps this is why @loladiro is downloading a newer version of libgnutls than what is available from WinRPM.

[mlubin]

Oh, I just assumed this was pre-WinRPM.

[ihnorton]

@mlubin this: https://github.com/loladiro/GnuTLS.jl/pull/17 appears to fix it.

[mlubin]

Thanks, never would've figured that out! It works for me now. @loladiro, could we merge and bump in METADATA? @IainNZ and I are on a short timeframe for the course we're teaching.

[IainNZ]

Apologetic bump, but I think this might be the only blocker for getting the webstack working on Windows.

[Keno]

I'll have a look.

[ihnorton]

@loladiro it seems necessary to set the memory handlers before calling set_system_trust or else we get https://github.com/loladiro/GnuTLS.jl/issues/14#issuecomment-32700049 ... This was just a hunch based on some gnutls list threads, and appears to be confirmed on both of our computers with #17 (which is kind of ugly, maybe there is a nicer way to arrange init() to happen first).

[mlubin]

Thanks for merging. Mind if I bump in METADATA?

[Keno]

Go ahead.

[mlubin]

Done.

[sbromberger]

Closing this out since it's over a year old. Assuming the issue has been fixed - if not, please let me know and I'll reopen.
