BUG: doxygen-1.5.0: doxywizard fails to build

[css@…]

The doxygen doxywizard fails to compile on Mac OS X with either qt3 or qt3-mac:

The full make error log reveals an inability to properly locate the Qt headers.

[css@…]

Even after correcting for locating the header files, the build process fails trying to link a universal library. Maybe the port shouldn't try a universal build?

[css@…]

Maybe the attempted universal build is to blame in this case? Since doxygen is building from source anyway, should it perhaps build only for the host architecture? It seems that universal builds are all-or-nothing. All dependencies need to build as universal binaries, and that could cause trouble for the ports tree.

See Building Universal Binaries from "configure"-based Open Source Projects.

[css@…]

The easy fix for this issue (admittedly maybe not the best) is to explicitly specify --platform macosx-c++ during the configure phase. This forces doxygen to build for the host processor. Building a universal binary via MacPorts is going to take a much larger effort with ramifications for dependencies. I will open a separate bug for a universal build of doxygen.

Fixed in r20637.
