Just an addendum in case someone else decides to go the route I attempted to describe above for Mac 10.11 (El Capitan). In that case, you will most probably end up frustrated after hitting compilation issues with QtWebEngine et al. (it refuses to compile out of the box). I have come across the following issues and went over them as explained below:
a) You will need to patch "qtwebengine/src/3rdparty/chromium/tools/gyp/pylib/gyp/xcode_emulation.py" with the following:
sdk_root = self._SdkPath(config_name)
if not sdk_root:
sdk_root = ''
----> return l.replace('$(SDKROOT)', sdk_root) <---- Replaced this line with the following block (below).
library = l.replace('$(SDKROOT)', sdk_root)
if l.startswith('$(SDKROOT)'):
basename, ext = os.path.splitext(library)
if ext == '.dylib' and not os.path.exists(library):
tbd_library = basename + '.tbd'
if os.path.exists(tbd_library):
library = tbd_library
return library
To see the original post about this "patch" refer to:
https://trac.macports.org/attachment/ticket/49074/patch-chromium_tbd_libraries.diff
b) Missing links to several libraries needed by QtWebEngine et al. Create symlinks to the respective and already existing libraries:
sudo ln -s /usr/lib/libz.dylib /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/lib/libz.dylib
sudo ln -s /usr/lib/libresolv.dylib /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/lib/libresolv.dylib
sudo ln -s /usr/lib/libbsm.dylib /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/lib/libbsm.dylib
sudo ln -s /usr/lib/libcups.dylib /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/lib/libcups.dylib
For the details on the above refer to the discussion about it here:
https://trac.macports.org/ticket/49074
Following the flow above I successfully compiled, linked, and installed the Qt-5.5.1 libraries, as well as QtCreator 3.5.1 after that (also from source). So far, everything seems to work fine...
