[Interest] Building Qt from Sources

[Jesus Fernandez]

Hello,

I have a RHEL5 workstation at work.

For building Qt Creator I use 2 scripts:
bin> cat buildQt
#!/bin/sh
export
LD_LIBRARY_PATH=/users/fernajes/paks/dbus/dbus-1.4.16/deploy/lib:/local/paks/gcc-4.6.0/deploy/lib:/local/paks/gmp\-4.3.2/deploy/lib:/local/paks/mpc-0.8.1/deploy/lib:/local/paks/mpfr-2.4.2/.libs:$LD_LIBRARY_PATH
export PATH=/local/paks/gcc-4.6.0/deploy/bin:$PATH
./configure -developer-build -commercial -confirm-license -no-qt3support
-dbus-linked -no-multimedia -no-audio-backend -no-phonon -no-openssl
-no-opengl -nomake demos -nomake examples -no-nis -no-cups -no-gtkstyle -I
/local/paks/dbus/dbus\-1.4.16/deploy/include/dbus-1.0
make -j 13

bin> cat buildQtCreator
#!/bin/bash
oldDir=$PWD
#qtDir=/local/paks/qt-everywhere-opensource-src-4.8.0
qtDir=/local/paks/qt-everywhere-opensource-src-4.7.4
deployDirectory=$oldDir/$1_deploy
echo "Old directory $oldDir"
echo "Building Qt Creator please wait...\n"
export
LD_LIBRARY_PATH=/local/paks/gcc-4.6.0/deploy/lib:/local/paks/mpc-0.8.1/deploy/lib:/local/paks/mpfr-2.4.2/.libs:$LD_LIBRARY_PATH
export PATH=/local/paks/gcc-4.6.0/deploy/bin:$PATH
echo "Using: "
$qtDir/bin/qmake --version
cd $1
$qtDir/bin/qmake
make -j 13
make INSTALL_ROOT="$deployDirectory" install -j 13
cp $qtDir/bin/qhelpgenerator $deployDirectory/bin

As you can see there is some dependencies that I need to resolve before
building Qt (dbus; gcc; mpc; mpfr)

I hope it helps you.
