我在系统中缺少什么？

Question

我正在用QT4编写应用程序。目前我已经安装了OpenSuse 11.4 x86_64。我需要为32位平台构建一个应用程序，因为我在这个版本中编译了一个包含的库。

在qt-Creator中，构建选项，我设置参数：-spec linux-g++-32。

g++ -m32 -o Faktura main.o mainwindow.o timer.o QueryAtlasFactory.o 
            MySqlQueryAtlas.o  moc_querythread.o moc_printthread.o 
            qrc_zasoby.o    
         -L/usr/lib64 /home/neon/workspace/qt4/Faktura/drukarki/elzab/elzabdr.a 
         -lQtSql -L/usr/lib64 
         -lQtGui 
         -L/usr/X11R6/lib64 -lQtCore 
         -lpthread 

不幸的是，编译器正在链接64位库并返回错误：

/usr/lib64/gcc/x86_64-suse-linux/4.5/../../../../x86_64-suse-linux/bin/ld: skipping incompatible /usr/lib64/libQtSql.so when searching for -lQtSql

问题是：我的系统中缺少什么来构建32位应用程序，或者我做错了什么？

Answer 1

-L/usr/lib32或-L/usr/lib而不是-L/usr/lib64呢？
