Qt5.7.0配置选项（configure非常详细的参数）

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。

一.源码目录、编译目录和安装目录

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。

1. mkdir ~/qt-build
2. cd ~/qt-build
3. ~/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。

1. ./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。

1. ./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。

1. ./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。

1. ./configure -platform linux-clang
2. ./configure -platform linux-g++
3. ./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。

1. configure.bat -platform win32-g++
2. 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。

1. 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。

1. 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。
