rxvt-unicode @9.20 fails to build

[harciga]

Undefined symbols for architecture i386

[ryandesign (Ryan Carsten Schmidt)]

The build fails because although you've requested an x86_64-only build, it's trying to compile some objects universal, for both x86_64 and i386, and trying to link them with the other objects that weren't built universal.

This appears to be happening because it's trying to use your OS X version of perl, which suffers from a problem that we already fixed in the MacPorts versions of perl some years ago (#24779). Your OS X version of perl is universal, and the -arch flags that Apple used to build perl are bleeding into the rxvt-unicode build.

The solution is to make sure rxvt-unicode's build always uses MacPorts perl, never OS X's perl. The portfile already specifies that it should be using ${prefix}/bin/perl. If you have the perl5 port installed, that should be a symlink to a MacPorts version of perl. Is it possible that you instead have /opt/local/bin/perl as a symlink to the system version of perl?

rxvt-unicode should probably switch to using an explicit version of MacPorts perl. At this time we are still recommending that perl5.16 be used for that.

Indeed my {$prefix}/bin/perl is linking to OS X's perl

This is with sudo port select perl perl5.12-apple.12

How am I supposed to fix this?

sudo port perl select lists the following

Available versions for perl:
	none
	perl5.10-apple.12
	perl5.12-apple.12 (active)

But I have other perl versions installed as stated by

sudo port installed perl*

The following ports are currently installed:
  perl5 @5.12.4_0+perl5_12 (active)
  perl5.12 @5.12.4_2
  perl5.12 @5.12.4_3
  perl5.12 @5.12.4_3+universal
  perl5.12 @5.12.5_0+universal (active)
  perl5.16 @5.16.1_3
  perl5.16 @5.16.3_0
  perl5.16 @5.16.3_0+universal (active)
  perl5.18 @5.18.2_0
  perl5.18 @5.18.2_1 (active)
  perl5.20 @5.20.0_2 (active)
  perl_select @0.3_0 (active)

*RESOLVED*

Please close.

#45866 was also a perl issue and it gave me an idea on how to solve this

I did a $ port install perl5 +perl5_20; port select perl none; port activate perl5@5.12.4_0+perl5_20

Now sudo port installed perl* outputs

The following ports are currently installed:
  perl5 @5.12.4_0+perl5_12
  perl5 @5.12.4_0+perl5_16
  perl5 @5.12.4_0+perl5_20 (active)
  perl5.12 @5.12.4_2
  perl5.12 @5.12.4_3
  perl5.12 @5.12.4_3+universal
  perl5.12 @5.12.5_0+universal (active)
  perl5.16 @5.16.1_3
  perl5.16 @5.16.3_0
  perl5.16 @5.16.3_0+universal (active)
  perl5.18 @5.18.2_0
  perl5.18 @5.18.2_1 (active)
  perl5.20 @5.20.0_2 (active)
  perl_select @0.3_0 (active)

I have no idea where perl5 @5.12.4_0+perl5_16 came from but everything built fine anyway.

Perhaps the depends_lib should require a port:perl5.16 instead of a file dependency as recommended in ​https://guide.macports.org/#reference.dependencies.types given that this specific port will never build on OS X's perl due to #24779
