Howto add Qt support for geordi revised

It’s time to write revised instructions for how to add Qt support for Geordi. The following versions were used:

  • GHC 6.10.2
  • Geordi 2009-04-18 (from darcs repo, num patches: 425)
  • Qt 4.5.0

Start with installing Qt inside Geordi rt:

./configure -prefix /path/to/geordi/rt/usr/local/Trolltech/Qt-4.5.0
make install

Add to prelude/prelude.hpp:


Recompile prelude:


Remove from compile-config/COMPILE_FLAGS:


Add to compile-config/COMPILE_FLAGS:

-D_REENTRANT -DQT_SHARED -DQT_CORE_LIB -I/usr/local/Trolltech/Qt-4.5.0/include -I/usr/local/Trolltech/Qt-4.5.0/include/QtCore -I/usr/local/Trolltech/Qt-4.5.0/mkspecs/linux-g++

Add to compile-config/LINK_FLAGS:

-Wl,-rpath,/usr/local/Trolltech/Qt-4.5.0/lib -L/usr/local/Trolltech/Qt-4.5.0/lib -lQtCore -lz -lm -pthread -lrt -ldl -lpthread

Copy libz, libm, libpthread, librt and libdl to geordi rt.

Modify src/EvalCxx.hsc and add the following to the list of ignored syscalls:

SYS_set_tid_address, SYS_set_robust_list, SYS_futex

In src/Cxx/Operations.hs, replace

expand (Print c c') = expand $ Block ([Plain "cout << "] ++ c ++ [Plain ";"]) c'


expand (Print c c') = expand $ Block ([Plain "qDebug() << "] ++ c ++ [Plain ";"]) c'

Rebuild and install the bot:

runhaskell Setup.hs build
sudo runhaskell Setup.hs install

That's it! Enjoy Geordi with Qt support! Thanks to Eelis for the tip about ignored syscalls!

    Side note: While updating the bot of mine and following these instructions I noticed that the prelude needs to be naturally compiled after modifying the compile-config. 😉
