VS2013编译Qt 5.7.0（兼容XP）

喜欢ヅ旅行 2022-04-18 01:46 735阅读 0赞

注意：编译时报以下错误

E:\\QtXP\\qtbase\\src\\3rdparty\\angle\\src\\libANGLE/renderer/d3d/d3d11/renderer11\_utils.h(33) : error C2065: “ID3D11RenderTargetView”: 未声明的标识符

解决方法为在第4步完成后，修改文件：E:\\QtXP\\qtbase\\src\\angle\\src\\config.pri，注释掉43行：\#equals(QMAKE\_TARGET\_OS, xp): CONFIG -= angle\_d3d11，然后再执行第5步及后面的操作.

--------------------

1. 下载Qt源码

[https://download.qt.io/archive/qt/5.7/5.7.0/single/qt-everywhere-opensource-src-5.7.0.zip][https_download.qt.io_archive_qt_5.7_5.7.0_single_qt-everywhere-opensource-src-5.7.0.zip]

2. 将源码解压缩，我放到了E盘根目录，然后将qt-everywhere-opensource-src-5.7.0文件夹名字改为QtXP

3. 在Qt目录下新建文件build.bat，内容如下：

REM Set up \\Microsoft Visual Studio 2013, where <arch> is \\c amd64, \\c x86, etc.  
  CALL "C:\\ProgramFiles\\Microsoft Visual Studio 12.0\\VC\\vcvarsall.bat" x86  
  SET \_ROOT=E:\\QtXP  
  SET PATH=%\_ROOT%\\qtbase\\bin;%\_ROOT%\\gnuwin32\\bin;%PATH%  
  REM Uncomment the below line when using a git checkout of the source repository  
  REM SET PATH=%\_ROOT%\\qtrepotools\\bin;%PATH%  
  SET QMAKESPEC=win32-msvc2013  
  SET \_ROOT=

4. 打开cmd窗口，cd进入E:\\QtXP，输入build.bat初始化编译环境

5. 输入命令：configure -prefix "E:\\QtXP\\build" -platform win32-msvc2013 \-target xp \-nomake tests -nomake examples -skip qtwebengine，初始化编译配置

6. 输入命令：nmake，开始漫长的编译............

编译完成后，可以在目录E:\\QtXP\\qtbase\\lib下找到Qt5Core.dll, Qt5Gui.dll等链接库文件，在目录E:\\QtXP\\qtbase\\plugins\\platforms下找到qwindows.dll等链接库文件. 也可以使用命令: nmake install 将头文件，库文件，exe和dll文件等安装到目录E:\\QtXP\\build

--------------------

//===============================================================================================

// 静态编译

打开 E:\\QtXP\\qtbase\\mkspecs\\common\\msvc-desktop.conf

将

QMAKE\_CFLAGS\_RELEASE    = -O2 \-MD  
QMAKE\_CFLAGS\_RELEASE\_WITH\_DEBUGINFO += -O2 \-MD \-Zi  
QMAKE\_CFLAGS\_DEBUG      = -Zi \-MDd

改为

QMAKE\_CFLAGS\_RELEASE    = -O2 \-MT  
QMAKE\_CFLAGS\_RELEASE\_WITH\_DEBUGINFO += -O2 \-MT \-Zi  
QMAKE\_CFLAGS\_DEBUG      = -Zi \-MTd

即将MD改成MT，MDd改成MTd。动态改成静态

使用命令：configure -prefix "E:\\QtXP\\build" -platform win32-msvc2013 \-target xp -static \-nomake tests -nomake examples -skip qtwebengine

VS2013工程需要做以下改动以进行静态链接

1. 属性 -> C/C++ -> 预处理器 -> 预处理器定义

QT\_DLL 修改为 QT\_STATIC

2. 属性 -> 链接器 -> 输入 -> 附加依赖项:

dxguid.lib
    d3d9.lib
    kernel32.lib
    user32.lib
    shell32.lib
    uuid.lib
    ole32.lib
    advapi32.lib
    ws2_32.lib
    gdi32.lib
    comdlg32.lib
    oleaut32.lib
    imm32.lib
    winmm.lib
    qtmaind.lib
    Qt5Cored.lib
    Qt5Guid.lib
    Qt5Widgetsd.lib
    qtpcred.lib
    libEGLd.lib
    libGLESv2d.lib
    Qt5OpenGLd.lib
    translatord.lib
    preprocessord.lib
    qwindowsd.lib
    qtfreetyped.lib
    qtharfbuzzngd.lib
    Qt5PlatformSupportd.lib

3. 修改main.cpp

#include <QtPlugin>
    Q_IMPORT_PLUGIN(QWindowsIntegrationPlugin);

configure是一个命令行工具，用于配置Qt编译到指定平台。configure必须运行于Qt源码根目录。当运行configure时，编译源码使用的是所选工具链中的make工具。

源码目录就是包含源码的目录。编译目录是包含Makefiles文件、object文件和其他中间文件的目录。安装目录是二进制文件和库文件安装的目录。

当编译目录和源码目录不一样时，称为影子编译（shadow build），比如说，Qt Creator默认是使用影子编译来编译工程的。这里也可以使用影子编译，方法就是新建一个目录，然后cd到该目录中运行configure，如下所示。

mkdir ~/qt-build  
cd ~/qt-build  
~/qt-source/configure  
此时，configure时生成的Makefiles文件，以及编译时生成的中间文件都会拷贝到qt-build目录。不仅如此，通过影子编译，可以同时进行多个不同配置选项的编译过程，互不影响。  
默认的安装目录和平台相关，但是在configure时，可以通过-prefix选项指定安装目录，比如./configure -prefix /opt/Qt-5.7。这样一来，在执行make install指令时，编译完成的bin、lib或者其他子目录就会拷贝到/opt/Qt-5.7目录中。  
二.包含和排除Qt模块

通过configure，可以包含或排除指定的Qt模块。需要注意的是，许多模块依赖于其他的模块，不恰当的配置选项会导致依赖问题。

1.排除Qt模块

使用configure的-skip选项可以排除Qt模块，一般情况下模块名就是源码目录中对应的子目录名。有些子目录会包含多个模块，比如说qtconnectivity目录就包含了Qt NFC模块和Qt Bluetooth模块，排除这两个模块需要将-skip qtconnectivity作为配置参数，如下所示。

./configure -skip qtconnectivity  
2.包含或排除特性  
\-feature-<feature> 和 -no-feature-<feature>选项用于包含和排除特性。可用的<feature>都被罗列在tbase/src/corelib/global/qfeatures.txt文件中。比如，要禁用accessibility特性，可用使用-no-feature-accessibility选项，如下所示。  
./configure -no-feature-accessibility  
三.第三方库  
Qt源码中包含了一些第三方库，如果想使用Qt自带的第三方库，可用通过-qt配置；如果想使用系统中的第三方库，可用通过-system配置。下表中列出一些第三方库及其配置选项。

Library Name    Bundled in Qt    Installed in System  
zlib    -qt-zlib    -system-zlib  
libjpeg    -qt-libjpeg    -system-libjpeg  
libpng    -qt-libpng    -system-libpng  
xcb    -qt-xcb    -system-xcb  
xkbcommon    -qt-xkbcommon    -system-xkbcommon  
freetype    -qt-freetype    -system-freetype  
PCRE    -qt-pcre    -system-pcre  
HarfBuzz-NG    -qt-harfbuzz    -system-harfbuzz  
当然，也可以禁用这些第三方库，用-no替换-qt就行，如下所示。  
./configure -no-zlib -qt-libjpeg -qt-libpng -system-xcb  
四.编译选项  
\-platform选项指定了目标平台和编译时使用的编译器，Qt支持的平台和编译器都在qtbase/mkspecs目录中。比如，在Ubuntu Linux系统中，Qt能被多种编译器编译，比如clang和g++，如下所示。

./configure -platform linux-clang  
./configure -platform linux-g++  
./configure -platform linux-g++-32  
对于Windows系统，可以用MinGW或者Visual Studio工具链，如下所示。  
configure.bat -platform win32-g++  
configure.bat -platform win32-msvc2010  
五.交叉编译选项  
通用的选项如下所示。

\-xplatform：指定目标平台，可用的xplatform与platform类似，也在qtbase/mkspecs目录中。

\-device：指定特殊的设备或芯片，configure兼容的device在qtbase/mkspecs/devices目录中。

\-device-option：设置额外的qmake参数，比如，-device-option CROSS\_COMPILE=<path-to-toolchain>提供了特定设备交叉编译所需的环境变量。  
六.Windows中使用OpenGL选项

在Windows中，Qt可以配置使用系统的OpenGL或者自带的ANGLE。默认情况下，Qt会配置使用ANGLE，ANGLE依赖于DirectX SDK。ANGLE使得依赖于OpenGL的Qt应用程序可以在没有安装OpenGL的机器上运行。

\-opengl选项可以配置Qt使用目标机器上的OpenGL，如下所示。

configure.bat -opengl desktop  
desktop选项告知Qt使用Windows上的OpenGL，当然前提是要求Windows上的OpenGL与Qt兼容。

\-opengl选项支持两个版本的OpenGL ES，一个是es2，一个是es1，如下所示。

configure.bat -opengl es2  
七.configure -h  
configure -h与configure -help功能相同，显示所有配置选项。以下是Windows上Qt5.7.0的配置选项。
