[vlc-devel] Problems with Mac OS X compile

[Dave Still]

I'm trying to compile latest git on Mac OS X 10.5.3 with latest X- 
Code / iPhone dev kit, and I'm running into some problems.  Using the  
instructions at http://wiki.videolan.org/OSXCompile , I'm configuring  
with "./configure --enable-debug --with-macosx-sdk", but configure  
fails with the following message:

...
checking dlfcn.h usability... no
checking dlfcn.h presence... yes
configure: WARNING: dlfcn.h: present but cannot be compiled
configure: WARNING: dlfcn.h:     check for missing prerequisite headers?
configure: WARNING: dlfcn.h: see the Autoconf documentation
configure: WARNING: dlfcn.h:     section "Present But Cannot Be  
Compiled"
configure: WARNING: dlfcn.h: proceeding with the preprocessor's result
configure: WARNING: dlfcn.h: in the future, the compiler will take  
precedence
checking for dlfcn.h... yes
checking how to run the C++ preprocessor... /lib/cpp
configure: error: C++ preprocessor "/lib/cpp" fails sanity check
See `config.log' for more details.

An examination of config.log reveals that /lib/cpp does not exist, but  
then again, it never did and I was able to compile on OS X before.   
When I try configuring with just "./configure", the config script  
completes, but I get the following compile error:

This leads me to ask two questions:

1. What is the proper compile procedure for Mac OS X? (i.e., is the  
current Wiki page correct?)
2. How can I (or someone) correct the error(s) that I'm getting?

Thanks,
