-Building universal binaries on Mac OS X (obsolete information)
---------------------------------------------------------------
-
-(This information was written when Mac OS X Leopard was the current
-release. It may no longer work.)
-
-Universal 32bit binaries can be built on an Intel Mac using the
-`--enable-darwin-universal` configure option. There still may occur
-problems with certain applications using this option, but the base
-system should run smoothly.
-
-When building universal binaries on a PowerPC Mac (at least on Tiger),
-you must point out a suitable SDK that contains universal binaries.
-For instance, to build universal binaries for Tiger (10.4):
-
-    $ CFLAGS="-isysroot /Developer/SDKs/MacOSX10.4u.sdk" \
-    LDFLAGS="-isysroot /Developer/SDKs/MacOSX10.4u.sdk" \
-    ./configure --enable-darwin-universal
-
-Also, if you run Leopard, but want to build for Tiger, you must do by
-setting the `MACOSX_DEPLOYMENT_TARGET` environmental variable.
-
-    $ export MACOSX_DEPLOYMENT_TARGET=10.4
-
-Experimental support for 64bit x86 darwin binaries can be enabled
-using the `--enable-darwin-64bit` configure flag. The 64bit binaries are
-best built and run on Leopard, but most of the system also works on
-Tiger (Tiger's 64bit libraries are, however, limited; therefore e.g. `odbc`,
-`crypto`, `ssl` etc. are not supported in Tiger). 64bit PPC binaries are not
-supported and we have no plans to add such support (no machines to
-test on).
-
-Universal binaries and 64bit binaries are mutually exclusive options.

-If you want to build the `wx` application, you will need to get wxMac-2.8.12
-(`wxMac-2.8.12.tar.gz` from
-<http://sourceforge.net/projects/wxwindows/files/2.8.12/>) and install it.
+If you want to build the `wx` application, you will need to get wxWidgets-2.9.4 (or later)

+or get it from github:
+    $ git clone [email protected]:wxWidgets/wxWidgets.git
 
-Export the path for MacOSX10.6.sdk:
+Be aware that the wxWidgets-2.9 branch is a development branch of wxWidgets and the MacOsX

-In Xcode 4.3 the path has changed so use the following instead,
-
-    $ export SDK=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.6.sdk

-Then configure and build wxMac:

+    $ ./configure --with-cocoa --prefix=/usr/local
     $ make
     $ sudo make install
+    $ export PATH=/usr/local/bin:$PATH
 
-To link wx properly you will also need to build and install `wxStyledTextCtrl`:
+Check that you got the correct wx-config
 
-    $ cd contrib/src/stc

 ### Finish up ###
 
 Build Erlang with the MacPorts GCC as the main compiler (using `clang`
 for the Objective-C Cocoa code in the `wx` application):
 
-    $ PATH=/usr/local/bin:$PATH CC=/opt/local/bin/gcc-mp-4.5 CXX=/opt/local/bin/g++-mp-4.5 ./configure --enable-m32-build make
