Created attachment 128438 [details, diff] unison-2.17.1-as-needed.patch -lutil must be after pty.o
I just encountered the same problem on my ~amd64 system. Any idea when this may hit portage?
Oops, I forgot to mention that the patch fixed the problem.
I'm getting the exact same error with unison-2.13.16 and use "--as-needed", as well. The particular machine I'm trying to rebuild unison on is running an amd64 install. I removed "--as-needed" from my LDFLAGS but unison would still not compile. I then stripped out all LDFLAGS I had in make.conf but unison would still not compile. I also, stripped down my CFLAGS but got the same error. I tried building unison-2.12.0-r1 but got the same results. This patch did fix the problem for unison-2.13.16 and unison-2.17.1-r1, however, I don't think the cause of this is due to "--as-needed".
unison is written in ocaml. Try to rebuild ocaml without --as-needed and then build unison...
*** Bug 193489 has been marked as a duplicate of this bug. ***
applied for 2.27.57, please dont forget to send it upstream as it was still needed for that version
dev-zero, maybe you want to send it upstream. I don't find an easy way to contact upstream and I don't even use unison.
