| # checks that follow, use the correct -m32 or -m64 flag for the |
| # primary target (called $mflag_primary). Otherwise, we can end up |
| # in a situation (eg) where, on amd64-linux, the test for Boost checks |
| # for usable 64-bit Boost facilities, but because we are doing a 32-bit |
| # only build (meaning, the primary target is x86-linux), the build |

| # - If pkg-config was not installed at the time autogen.sh was run, |

| # autogen.sh. Augogen.sh will generate a configure script that prints |
| # a warning about pkg-config and proceeds as if Qt4 has not been installed. |
| # - If pkg-config was installed at the time autogen.sh was run, |
| # the generated configure script will try to detect the presence of the |
| # Qt4 QtCore library by looking up compile and linker flags in the file |
| # called QtCore.pc. |
| # - pkg-config settings can be overridden via the configure variables |
| # QTCORE_CFLAGS and QTCORE_LIBS (added by the pkg-config m4 macro's to the |
| # configure script -- see also ./configure --help). |
| # - The QTCORE_CFLAGS and QTCORE_LIBS configure variables can be used even if |
