Hello,
an attempt to cabal install -fportable snap -- on Solaris 11 with GHC 7.10.1 fails with:

I think I fixed this with commit snapframework/snap-core@1105904. Can you try it and see if it's fixed for you before I upload to hackage?

[kgardas]

This works for me. Thanks for the patch. Now, on Solaris 11 we still do have issue with undefined timegm function, but that's another story:

timegm is used in snap-core. Why don't you open another issue on the snap-core package with more details?

[kgardas]

I think I was wrong and this fix is not the correct one. You have basically removed -DPORTABLE for GHC 7.10.1 and this causes timegm linking issue. The problem is that -fportable was working fine on Solaris 11 in the past, see #136

[kgardas]

I've found that similar issue is already reported and hopefully fixed in HEAD, it's snap-core#228 snapframework/snap-core#228

[kgardas]

I've tested HEAD (1.0.0.0 version) and this is working fine on Solaris 11 with -fportable.

Thanks for following up with this. I reverted my commit and applied the patch from the master branch.
