   That looks like two problems to me.

   1. the carbon include isn't working
   2. libbio got built as 64 bit

   Does that sound right?
2. #2 mennis

   written 2011-07-30

   I think this means everything is built as 32 bit.

   $ FILES=`du -a | grep "\.o$"|cut -f2`
   $ for f in $FILES; do file $f; done | grep "Mach-O object i386" | wc
       1433    5732   63729
   $ for f in $FILES; do file $f; done | grep -v "Mach-O object i386" | wc
          0       0       0
   

   Linker issue?

   I am able to compile on 10.6.8 and use that copy on 10.7.

   • Changed status from new to resolved.

   Should be fixed by most recent checkin.

   Actually, I take it back. The reported errors are fixed but you probably still need to copy $PLAN9/bin/devdraw from an older system.

   Using 3266:1ddb9b093c12 besides carbon issues I get these two errors.

   Xcode 4 is screwing the .a files

   [mac:bin]$ cat Darwin/ar

   1. !/bin/sh shift exec libtool -static -o $@

   this works for me... maybe 9ar needs the magic

    I got the same error on a program of mine. It is solved by running ranlib after ar and before ld. The problem is ld not being able to generate the archive TOC on its own.

    • Changed status from open to resolved.

    With some recent fixes, everything seems fine using Lion and the recently released-to-App-Store Xcode 4.2.
