openssl + std.conv = Linker error

[trikko]

Reduced test:

import deimos.openssl.evp;

int bla()(string d)
{
   import std;
   SysTime.fromISOString(d);
   return 0;
}

void main()
{
   bla("");
}

Output:

/usr/bin/ld: /home/andrea/.dub/cache/error/~master/build/application-debug-Hq7anUdmLGjuab75LyZkvA/error.o: in function `_D3std4conv__T2toTkZ__TQjTAyaZQqFNaNfQlZk':

Reduced:

main.d

import test;

int main() {return 0;}

auto blabla(string d) {
   import std;
   SysTime.fromISOString(d);
}

test.di:

module test;

enum XXX = bla("1.1");

int bla()(string s)
{
   import std;
   s.splitter('.').front.to!uint;
   return 0;
}

dmd -i main.d

[CyberShadow]

Well, it's a DMD bug. Please file this to https://issues.dlang.org/ too.

We can try a workaround here (e.g. avoid using Phobos).

[trikko]

Why only if test.di and not test.d?

[CyberShadow]

Such is bug.

We use .di to avoid having to link the bindings, so it is "header-only". But this is not used often and therefore bugs happen.

@trikko Can you test if #108 fixes building your real (non-reduced) project?
