Created attachment 197471 [details] patch USES=compiler:c++11-lang is necessary to compile this port with architectures that have GCC in base. Also, add USES=gnome. Tested on powerpc64 and amd64. Hardware sponsored by IntegriCloud.
Thanks for the PR. Currently an update for 17.1 is open. There are problems here, and I have no time for. You are welcome to try to do it if you want.
(In reply to Jochen Neumeister from comment #1) What? There's no claws-mail 17.1.
sorry, 3.17.1
(In reply to Jochen Neumeister from comment #3) I don't use claws-mail, I'm just fixing all ports that don't build on powerpc64. You don't need much time here, it's just adding two USES.
