[MacRuby-devel] macruby does not compile for me on Lion with xcode 4.1

[Marvin Frick]

Hi,

I have some trouble compiling MacRuby on Lion with XCode 4.1.
As some tickets in the trac indicate that people are using macruby on lion, i think this might be a problem with my setup. As said, its a MacOSX Lion with xcode 4.1 build 4B110 (got it from the appstore just yesterday).

I checked out 0.10 from github.com and rake'd it:

In file included from kernel.c:19:
encoding.h:22:30: error: unicode/ustring.h: No such file or directory

This seems reasonable since unicode/*.h is in icu-1060/. Shouldnt these header files come with xcode anyway?
After my silly approach of copying the files into the include folder, the compiler does find the needed deklarations and the rake process goes on. However, some files later:

/usr/bin/gcc-4.2 -std=c99 -I. -I./include -pipe -fno-common -fexceptions -fblocks -g -O3 -Wall -Wno-deprecated-declarations -Werror -arch x86_64  -c gc.c -o .objs/gc.o
gc.c: In function ‘ruby_xmalloc_ptrs’:
gc.c:130: error: ‘AUTO_MEMORY_ALL_POINTERS’ undeclared (first use in this function)
gc.c:130: error: (Each undeclared identifier is reported only once
gc.c:130: error: for each function it appears in.)
rake aborted!

The few google results on "AUTO_MEMORY_ALL_POINTERS" reveals that this comes from CoreFoundations CoreFoundation_Prefix.h. Unforunately this file does not exist in any CoreFoundation Frameworks (neither iOS, nor MacOSX) in /Developer on my Mac. 

About my system:

LLVM 2.9 build with homebrew.

Before I upgarded to Lion a ran SnowLeopard with LLVM 2.9 from homebrew and and older xcode 3.something and it compiled and ran perfectly.

What might got wrong here?
Any hints appreciated!

Thanks!
