Qt4 with X11 on Mac OSX Lion/Snow Leopard
-
I have been trying to install the open source edition of Qt 4.8.2 from source and link to X11 without success. I am currently running OSX 10.7.4. My research group uses some analysis software that uses PyQt4. Most of our other analysis packages still use X11. Also, we have a mac server (running OSX 10.6.8) that we only log into using ssh, so we would like to have the forwarding capability of X11. I have been able to build from the qt source successfully by just running ./configure; make; make install. However, this links to the native Cocoa libraries as one would expect. I have searched for explanations on how to link to X11 instead with little success. I have tried to simply create a different mkspecs folder named linux-g++-mac as suggested in one post, but I get the following errors:
/usr/local/qt-everywhere-opensource-src-4.8.2/src/corelib/io/qfile.cpp:1259: error: ‘::lseek64’ has not been declared
/usr/local/qt-everywhere-opensource-src-4.8.2/src/corelib/io/qfile.cpp:1259: error: ‘off64_t’ was not declared in this scopeI am aware that there is a fink package qt4-base-x11. I have worked on installing this, but it has been slow going trying to resolve all of the inconsistent dependencies in the dependencies of qt4-x11 (not qt4-x11 itself). I would prefer to simply install this directly from source if possible. I did try to use the fink info file as an example of the commands I should use to build from source which has gotten me the farthest along in the build. I ran the following perl commands to patch a few files as from the fink build:
perl -pi -e 's,const char,char,g' config.tests/unix/iconv/.cpp
perl -pi -e 's,CFG_MAC_XARCH=auto,CFG_MAC_XARCH=no,g' configureI then ran the following configure command:
./configure -x11 -platform darwin-g++ -xplatform darwin-g++ -arch x86_64 -confirm-license -verbose -no-separate-debug-info -L/usr/X11/lib -I/usr/X11/include -no-pch ; make; make installI have tried this both the XCode gcc and g++ and clang. I did not expect the clang build to work as I have seen other posts about issues with the clang compiler.
The configure script runs through completely with almost no warnings. The only warnings I see are a set of warnings like the following:
WARNING: Failure to find: generated/AuthenticationManagerMessageReceiver.cpp
WARNING: Failure to find: generated/DownloadProxyMessageReceiver.cpp
WARNING: Failure to find: generated/DrawingAreaMessageReceiver.cpp
...The only warnings that concerned me were:

Is it possible to compile Qt4 against X11 from source? Thank you for your time and help with this issue.
