使用GCC4.4，Qt4.7.4编译QtLua revision 221

编译后不能在Qt4.7.4下使用，QtLua官方只支持Qt4.8以上版本　

直接上patch

郁闷的是，编译居然没通过，出错

CMakeFiles\qtlua.dir/objects.a(qtluaenum.cc.obj):qtluaenum.cc:(.text$_ZNK5QtLua10RefobjBase5_dropEv[QtLua::RefobjBase::_drop() const]+0x3e): undefined reference to `__sync_sub_and_fetch_4'

google大师说：“Update your GCC tool-chain. Or try to add -march=pentium or -march=i486, etc.”

于是，CMakeLists.txt就多了这行

SET(CMAKE_CXX_FLAGS "-march=i486" CACHE STRING "Architecture to tell gcc to optimize for (-march)")

好吧，删除编译目录，重新编译

出错，错误同上

 

晕，人品大爆发了，看看CXX_FLAGS有什么

libqtlua-build\src\CMakeFiles\qtlua/includes_CXX.rsp 

-isystem y:/Qt/qt474/mingw/include -isystem y:/Qt/qt474/mingw/include/QtUiTools -isystem y:/Qt/qt474/mingw/include/QtGui -isystem y:/Qt/qt474/mingw/include/QtXml -isystem y:/Qt/qt474/mingw/include/QtCore -Iy:/develop/Lua51/include -IE:/myworkspace/libqtlua/libqtlua-build -IE:/myworkspace/libqtlua/libqtlua/src -Iy:/Qt/qt474/mingw/mkspecs/default

把-march=i486加到前面，编译，通过了:)
