libiconv and universal variant on a Mac PPC

[philippe.bernery@…]

I've got the following error when trying to compile libiconv with the +universal variant (configured in the global config file of macports) on a Mac PPC:

This is a known problem that can't easily be solved.

Libiconv include the prefix it's supposed to be installed to. If a single-arch version of libiconv is already installed, libiconv +universal will try to link against the installed single-arch libraries, resulting in the above errors.

A workaround is to uninstall/deactivate the single-arch version.

I have no libiconv installed except the one installed with Mac OS X (10.4). I uninstalled everything (with 'sudo port uninstall installed') before re-installing with the +universal variant.

Don't forget to Cc the assignee! I only found this bug today by coincidence.

Hi, I encountered the same problem. libiconv @1.11_4+universal fails to build on PPC-based Macs.

Anyway, here is a workaround to avoid this issue.

# In my view, configure.universal_ldflags variable should contain # this flag (-isysroot /Developer/SDKs/MacOSX10.4u.sdk) by default.

# In my view, configure.universal_ldflags variable should contain # this flag (-isysroot /Developer/SDKs/MacOSX10.4u.sdk) by default.

Sorry, please ignore my last comment. It was a bad idea since ld cannot handle -isysroot flag, as you know.

#12785 is a duplicate.

Sorry, I misread the comments before. I thought a fix had been proposed, then immediately declared no good. I see now that the fix to the portfile was ok, but that the proposed general-purpose fix was no good.

I committed what I thought was a better version of the change in r31117, then changed my mind and committed exactly what takanori wrote in r31118. Thanks to takanori for your help, and sorry to everyone for the delay.
