Compiling on Ubuntu 64bit for 32bit - App looks bad
Hi, I have written app and when I will compile it for 64bit version, it looks well. But if I will compile it for 32bit, no matter if with dynamic or static linking of Qt libs, it looks bad. I’m running Ubuntu 64-bit and using qmake. If I’m compiling for 32bit, I’m using 32bit version of qmake.My pro file:
- QT += core gui
- CONFIG += 32bit
- CONFIG(32bit) {
- TARGET = 5inRow32
- QMAKE_CXXFLAGS += -m32
- LIBS += -L/opt/Qt-32b//lib -lQtGui -L/opt/Qt-32b/lib -lXext -lX11 -lQtCore -lm -ldl -lrt -lpthread
- }
- CONFIG(64bit) {
- TARGET = 5inRow64
- }
- QMAKE_LFLAGS += -Wl,-rpath=\'\$\$ORIGIN\'
- TEMPLATE = app
- SOURCES += main.cpp\
- mainwindow.cpp \
- board.cpp \
- settings.cpp \
- fiveinrowai.cpp
- HEADERS += mainwindow.h \
- board.h \
- settings.h \
- fiveinrowai.h
Thanks in advise.

Yes, its ugly style, like win98. It is game 5 in row and circles painted on board look also awful. Image will be more ilustrative: http://i56.tinypic.com/14kl2k8.png
But even if I will run it on 32bit Ubuntu, it looks that ugly.
Then run ldd to see which library you are linking on your 32bit deployment target. In your case QGtkStyle is delivering the correct styling and it does so by asking gtk’s theme engine. Of course that can only work with dynamically linked dlls build for your target system. 32bit libs on your 64 bit system are most likely compiled without gtk style support.
ldd shows this:
- shima@debian:/mnt/hgfs/Shared Folder/Unix X11 32bit$ ldd ./5inRow32

So I have to install different package with GTK style support? Could you give me advise which package is it?
Qt library is distributed with app and its linked correctly. I’ve used libs compiled on my deployment machine (Ubuntu 10.04 64-bit) with Qt lib conf:
- ./configure -prefix /opt/Qt-32b -platform linux-g++-32b -release -nomake demos -nomake examples
- make sub-src
and then build it this way:
- PATH=/opt/Qt-32b/bin:$PATH
- export PATH
- qmake -config -release
- make && make clean
and put Qt libs to folder with app.
.pro file is above.
Maybe I’ve missed something.
