在.pro文件中强制执行32位程序

force 32 bits program in .pro file

本文关键字：32位 程序 强制执行 pro 文件      更新时间：2023-10-16

我知道我可以从命令行运行qmake并使用：

-spec linux-g++-32

从.pro文件中，我尝试将"-m32"或"-32"添加到"CFLAGS"或"QMAKE_CXFLAGS"中，但不起作用。

CFLAGS += -m32
QMAKE_CXXFLAGS += -m32

那我该怎么办？

这就是上面的旗帜所产生的。。。

好的，重点是：

生成的makefile（通过QtCreator）和我的命令行生成的makefile之间的差异是：

INCPATH       = -I/Soft/fox_dev/Qt-4.7.4/mkspecs/linux-g++-32 -I. -I/Soft/fox_dev/Qt-4.7.4/include/QtCore -I/Soft/fox_dev/Qt-4.7.4/include/QtXml -I/Soft/fox_dev/Qt-4.7.4/include/QtXmlPatterns -I/Soft/fox_dev/Qt-4.7.4/include -I../../../fx/libfx -I../../../fx/MQLib -I/Soft/fox_dev/boost/boost_1_54_0 -I/Soft/fox_dev/xerces-c-3.1.1-x86-linux-gcc-3.4/include -I/Soft/fox_dev/xerces-c-3.1.1-x86-linux-gcc-3.4/include -I.

与

INCPATH       = -I/Soft/fox_dev/Qt-4.7.4/mkspecs/linux-g++ -I../fxa_march -I/Soft/fox_dev/Qt-4.7.4/include/QtCore -I/Soft/fox_dev/Qt-4.7.4/include/QtXml -I/Soft/fox_dev/Qt-4.7.4/include/QtXmlPatterns -I/Soft/fox_dev/Qt-4.7.4/include -I../../../fx/libfx -I../../../fx/MQLib -I/Soft/fox_dev/boost/boost_1_54_0 -I/Soft/fox_dev/xerces-c-3.1.1-x86-linux-gcc-3.4/include -I/Soft/fox_dev/xerces-c-3.1.1-x86-linux-gcc-3.4/include -I. -I../fxa_march -I.

然而，可以转到"项目->构建设置->[选择要修改的配置]->并编辑带有附加参数的"Qmake步骤"：

-spec linux-g++-32

您还需要在.pro文件中添加以下任一项：

CFLAGS += -m32
QMAKE_CXXFLAGS += -m32

在.pro文件中，尝试在前缀为win32 的范围内写入所有命令

win32 {
     SOURCES += paintwidget_win.cpp
     # ...
 }

只有在设置了win32变量的情况下，才会运行作用域内的命令。
