Patches needed for wxPython for Mac OS X 10.10 Yosemite

I updated to the Developer's Beta for Yosemite and realized my build for KiCAD no longer works!!! I decided to build it again, using the Beta release of Xcode 6, and wanted to post my findings.

Some compilation errors are occurring on Mac OS X 10.10 Yosemite. If you can, add or modify your patches to support these modifications (in the future). All changes needed to build KiCAD have been noted below.

I'm not sure why these errors are occurring, since most of the changes shouldn't have been needed in the first place. It may just be because Yosemite is in beta, but these changes are needed at this time.

Error 1:

~/Downloads/KicadOSXBuilder-master/src/wxPython-src 2.9.4.0/src/osx/cocoa/utils.mm:250:28: error: cannot initialize a parameter of type 'id<NSFileManagerDelegate>' with an lvalue of type 'wxNSAppController *' [NSApp setDelegate:appcontroller];

Solution: In file /src/wxPython-src 2.9.4.0/src/osx/cocoa/utils.mm Line 250

Change:

[NSApp setDelegate:appcontroller];

To:

[[NSApplication sharedApplication] setDelegate:appcontroller];

Error 2:

~/Downloads/KicadOSXBuilder-master/src/wxPython-src 2.9.4.0/src/osx/webview_webkit.mm:927:25: error: cannot initialize a variable of type 'WebBackForwardList *' with an rvalue of type 'WKBackForwardList *' WebBackForwardList* history = [m_webView backForwardList];

Solution: In file src/wxPython-src 2.9.4.0/src/osx/webview_webkit.mm Line 927 & 945

Change:

WebBackForwardList* history = [m_webView backForwardList];

To:

WebBackForwardList* history = (WebBackForwardList *)[m_webView backForwardList];

Error 3:

CMake Error at pcbnew/CMakeLists.txt:713 (add_dependencies): Cannot add target-level dependencies to non-existent target "osx_fix_bundles".

Solution: In file build.sh Line 10 Change:

KICAD_BRANCH="lp:kicad"

To:

KICAD_BRANCH="lp:kicad/stable"

Line 393 Add:

-DKICAD_STABLE_VERSION=ON

To the parameters of:

cmake $SOURCE_DIRECTORY/$KICAD_DIRECTORY

Also, the patch for CMAKE may need to be updated if you are getting errors during the build stage of KiCAD. If so, create another patch file named "11_kicad_cmake-osx.patch" with the following code:

Another (possibly optional) dependency should be added to the Readme - Doxygen . Run sudo port install doxygen.
