Snow Leopard
------------
Requirements
* XCode Tools (http://developer.apple.com/tools/xcode)
* bzr (bazaar)
* CMake (http://www.cmake.org)
* wxWidgets 2.9 (http://www.wxwidgets.org/downloads)
* Doxygen (http://www.doxygen.nl)
* ccache (http://www.macports.org)
Building wxWidgets 2.9 Universal
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To check if your tools and libraries are installed check with file for architectures.
user@macosx$ file /Developer/SDKs/MacOSX10.5.sdk/usr/lib/libSystem.dylib
/Developer/SDKs/MacOSX10.5.sdk/usr/lib/libSystem.dylib: Mach-O universal binary with 4 architectures
/Developer/SDKs/MacOSX10.5.sdk/usr/lib/libSystem.dylib (for architecture ppc7400): Mach-O dynamically linked shared library stub ppc
/Developer/SDKs/MacOSX10.5.sdk/usr/lib/libSystem.dylib (for architecture ppc64)Mach-O 64-bit dynamically linked shared library stub ppc64
/Developer/SDKs/MacOSX10.5.sdk/usr/lib/libSystem.dylib (for architecture i386):Mach-O dynamically linked shared library stub i386
/Developer/SDKs/MacOSX10.5.sdk/usr/lib/libSystem.dylib (for architecture x86_64): Mach-O 64-bit dynamically linked shared library stub x86_64
You need the architectures what you are compiling for !
If you have problems that the 64bits library is not build you should add in
the configure file:
At time of writing (2009-01-16) this is on line 18381
changing this: OSX_UNIV_OPTS="-arch ppc -arch i386"
into this: OSX_UNIV_OPTS="-arch ppc -arch i386 -arch x86_64"
Building a universal monolib wxWidgets 2.9 with the following parameters:
./configure --enable-unicode=yes --enable-shared=no --enable-monolithic --with-opengl --with-expat=builtin --enable-universal_binary --enable-aui --enable-debug --with-osx_cocoa --with-macosx-sdk=/Developer/SDKs/MacOSX10.5.sdk/ --prefix=/opt/wxwidgets/<rev>
<rev> Should be subsituded with the revision from SVN
Then you should a message like this:
Configured wxWidgets 2.9.2 for `i686-apple-darwin10.4.0'
Which GUI toolkit should wxWidgets use? osx_cocoa
Should wxWidgets be compiled into single library? yes
Should wxWidgets be linked as a shared library? no
Should wxWidgets support Unicode? yes (using UTF-8)
What level of wxWidgets compatibility should be enabled?
wxWidgets 2.6 no
wxWidgets 2.8 yes
Which libraries should wxWidgets use?
STL no
jpeg builtin
png builtin
regex builtin
tiff builtin
zlib sys
expat builtin
libmspack no
sdl no
If you don't need the debugging symbols then you can remove the --enable-debug parameter.
Compiling and installing:
make
sudo make install
Move the old Mac OS X wxconfig and symlink it to the new compiled 2.9
sudo mv /usr/bin/wx-config /usr/bin/wx-config.osx
sudo ln -s /opt/wxwidgets-svn/bin/wx-config /usr
Building KiCad
~~~~~~~~~~~~~~
Extract the sources or get them from subversion.
user@mac-osx$ cmake .
Regarding Kicad the only things i've changed are the Variables
in the generated CMakeCache.txt
It depends on which CMake version you use:
//Flags used by the compiler during all build types.
//This fixes also BOOST macro errors
CMAKE_CXX_FLAGS:STRING=-D__ASSERTMACROS__
//Build architectures for OSX
CMAKE_OSX_ARCHITECTURES:STRING=x86_64 -arch i386 -arch ppc -isysroot /Developer/SDKs/MacOSX10.5.sdk/ -mmacosx-version-min=10.5
//The product will be built against the headers and libraries located
// inside the indicated SDK.
CMAKE_OSX_SYSROOT:PATH=/Developer/SDKs/MacOSX10.5.sdk
//Minimum OS X version to target for deployment (at runtime); newer
// APIs weak linked. Set to empty string for default value.
CMAKE_OSX_DEPLOYMENT_TARGET:STRING=10.5
Or:
CMAKE_OSX_ARCHITECTURE = x86_64 -arch i386 -arch ppc -isysroot /Developer/SDKs/MacOSX10.5.sdk/ -mmacosx-version-min=10.5
CMAKE_OSX_SYSROOT = /Developer/SDKs/MacOSX10.5.sdk
CMAKE_CXX_FLAGS = -D__ASSERTMACROS__
Then we invoke make:
user@mac-osx$ make
It is also possible to give all the options on the commandline and not to edit the CMakeCache.txt. This is a oneliner for Leopard and up:
cmake ~/Repositories/testing -DKICAD_TESTING_VERSION=ON -DCMAKE_OSX_ARCHITECTURES="i386 -arch x86_64 -isysroot /Developer/SDKs/MacOSX10.6.sdk -mmacosx-version-min=10.6" -DCMAKE_CXX_FLAGS="-D__ASSERTMACROS__" -DCMAKE_OSX_SYSROOT="/Developer/SDKs/MacOSX10.6.sdk"
Optional compiler cache
~~~~~~~~~~~~~~~~~~~~~~~
If you (re)compile often, you would love to use cache. The best is to install it using macports and set the libexec symlink
directory of ccache in your PATH variable.
Then start with a clean directory and invoke cmake, make sure that the C++ compiler points to /opt/local/libexec/ccache/g++

error: macro "check" passed 2 arguments, but takes just 1
CMAKE_CXX_FLAGS = -D__ASSERTMACROS__ fixes this :-)
configure:18585: gcc -isysroot /Developer/SDKs/MacOSX10.5.sdk/ -mmacosx-version-min=10.5 -o conftest -arch i386 -arch x86_64 -arch ppc -arch i386 -arch x86_64 -arch ppc conftest.c >&5
ld: warning: in /Developer/SDKs/MacOSX10.5.sdk//usr/lib/libSystem.dylib, missing required architecture ppc in file
Installing rosetta and xcode with all architectures fixes this "problem"
ld: warning: in /Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks//QuickTime.framework/QuickTime, missing required architecture x86_64 in file
You get this error because the QuickTime 10.6 framework is not build with 64bit support. This not a real issue for KiCad because we don't use it anyway.
Undefined symbols:

Make sure you marked the build type Release:
//Choose the type of build, options are: None(CMAKE_CXX_FLAGS or
// CMAKE_C_FLAGS used) Debug Release RelWithDebInfo MinSizeRel.
CMAKE_BUILD_TYPE:STRING=Release
