MinGW编译Qt

测试机器：windows7 x64, mingw32, qt-4.8.5
1) 下载qt的源代码
http://download.qt-project.org/official_releases/qt/4.8/4.8.5/qt-everywhere-opensource-src-4.8.5.tar.gz
2) 下载mingw32工具链
git clone git://code.csdn.net/wuzh1230/bitcoin.git
3) 解压并配置
最好是在干净的代码上做一个git备份，否则qt太大，很难察觉那些文件修改了。
git init . && git add . && git commit -m "add clean sources"
配置：
使用windows的configure.exe执行配置命令，否则qmake会使用Makefile.unix构建，进而失败。
用help看看qt configure options那些事儿

配置并生成qmake
configure.exe -platform win32-g++ -opensource -confirm-license -release -shared -nis -no-s60
如果需要openssl支持，请构建openssl，或者到楼主的git上下载预编译的oenssl。然后在mingw命令行下使用以下脚本配置Qt：
（可能需要把/d/cifs/lab这样的cygwin路径换成d:/cifs/lab这样的windows路径）
configure.exe \
-I /d/cifs/lab/csdn/bitcoin/3rd/openssl-1.0.1c-mgw/include \
-L /d/cifs/lab/csdn/bitcoin/3rd/openssl-1.0.1c-mgw/lib \

删除了
-no-accessibility \因为codecs需要accessibility支持。
如何加速编译过程？
-nomake demos, -nomake examples, -nomake tools
庞大的examples会消耗很多编译时间和磁盘空间。
请检查一下哪些组件启用了，那些Feature包含了。
Qt is now configured for building. Just run mingw32-make. To reconfigure, run mingw32-make confclean and configure.
4）生成qt库
mingw32-make
早上来一看，\src\plugins\bearer\nativewifi\main.cpp失败，原因是间接引用了<wctypes.h>但是没有引用windows平台头文件在前，修改platformdefs.h
index 4e0f6d5..7f8abf2 100644 --- a/src/plugins/bearer/nativewifi/platformdefs.h +++ b/src/plugins/bearer/nativewifi/platformdefs.h @@ -42,7 +42,10 @@ #ifndef PLATFORMDEFS_H #define PLATFORMDEFS_H -#include <wtypes.h> +#ifdef Q_OS_WIN +#include "../platformdefs_win.h" +#endif + #undef interface //proper header is wlanapi.h, but that is not included in windows XP
或者修改mingw的头文件， #2047
大概又过了1个小时，构建完成

5) 安装
mingw32-make install INSTALL_ROOT=dest也要很长时间。。。
而且安装位置在哪里呢？
如果当前路径是d:\abc\qt-source\，会安装到d:\dest\abc\qt-source\，why？
6) 用Qt库构建程序
三个步骤
6.1) 设置qmake的路径到path下，也就是上图安装后的目录的bin目录。
$ export PATH=$PATH:/d/cifs/lab/csdn/bitcoin/3rd/qt-4.8.5-mingw32-4.8.1/bin
6.2) 到example目录下找一个sample，执行qmake生成Makefile
Administrator@harrywu-PC /d/cifs/lab/csdn/bitcoin/3rd/qt-4.8.5-mingw32-4.8.1/examples/dialogs $ cd findfiles/ Administrator@harrywu-PC /d/cifs/lab/csdn/bitcoin/3rd/qt-4.8.5-mingw32-4.8.1/examples/dialogs/findfiles $ ls findfiles.exe findfiles.pro main.cpp window.cpp window.h Administrator@harrywu-PC /d/cifs/lab/csdn/bitcoin/3rd/qt-4.8.5-mingw32-4.8.1/examples/dialogs/findfiles $ qmake Administrator@harrywu-PC /d/cifs/lab/csdn/bitcoin/3rd/qt-4.8.5-mingw32-4.8.1/examples/dialogs/findfiles $ ls Makefile Makefile.Release findfiles.exe main.cpp window.cpp Makefile.Debug debug findfiles.pro release window.h
6.3) 执行make relase生成测试例子
Administrator@harrywu-PC /d/cifs/lab/csdn/bitcoin/3rd/qt-4.8.5-mingw32-4.8.1/examples/dialogs/findfiles $ make release make -f Makefile.Release make[1]: Entering directory `/d/cifs/lab/csdn/bitcoin/3rd/qt-4.8.5-mingw32-4.8.1/examples/dialogs/findfiles' g++ -c -pipe -O2 -frtti -fexceptions -mthreads -Wall -Wextra -DUNICODE -DQT_DLL -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -DQT_HAVE_MMX -DQT_HAVE_3DNOW -DQT_HAVE_SSE -DQT_HAVE_MMXEXT -DQT_HAVE_SSE2 -DQT_THREAD_SUPPORT -DQT_NEEDS_QMAIN -I'd:/ cifs/lab/temp/buildqt/qt-everywhere-opensource-src-4.8.5/include/QtCore' -I'd:/cifs/lab/temp/buildqt/qt-everywhere-opens ource-src-4.8.5/include/QtGui' -I'd:/cifs/lab/temp/buildqt/qt-everywhere-opensource-src-4.8.5/include' -I'd:/cifs/lab/te mp/buildqt/qt-everywhere-opensource-src-4.8.5/include/ActiveQt' -I'release' -I'd:/cifs/lab/temp/buildqt/qt-everywhere-op ensource-src-4.8.5/mkspecs/default' -o release/main.o main.cpp g++ -c -pipe -O2 -frtti -fexceptions -mthreads -Wall -Wextra -DUNICODE -DQT_DLL -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -DQT_HAVE_MMX -DQT_HAVE_3DNOW -DQT_HAVE_SSE -DQT_HAVE_MMXEXT -DQT_HAVE_SSE2 -DQT_THREAD_SUPPORT -DQT_NEEDS_QMAIN -I'd:/ cifs/lab/temp/buildqt/qt-everywhere-opensource-src-4.8.5/include/QtCore' -I'd:/cifs/lab/temp/buildqt/qt-everywhere-opens ource-src-4.8.5/include/QtGui' -I'd:/cifs/lab/temp/buildqt/qt-everywhere-opensource-src-4.8.5/include' -I'd:/cifs/lab/te mp/buildqt/qt-everywhere-opensource-src-4.8.5/include/ActiveQt' -I'release' -I'd:/cifs/lab/temp/buildqt/qt-everywhere-op ensource-src-4.8.5/mkspecs/default' -o release/window.o window.cpp D:/cifs/lab/temp/buildqt/qt-everywhere-opensource-src-4.8.5/bin/moc.exe -DUNICODE -DQT_DLL -DQT_NO_DEBUG -DQT_GUI_LIB -D QT_CORE_LIB -DQT_HAVE_MMX -DQT_HAVE_3DNOW -DQT_HAVE_SSE -DQT_HAVE_MMXEXT -DQT_HAVE_SSE2 -DQT_THREAD_SUPPORT -DQT_NEEDS_Q MAIN -I'd:/cifs/lab/temp/buildqt/qt-everywhere-opensource-src-4.8.5/include/QtCore' -I'd:/cifs/lab/temp/buildqt/qt-every where-opensource-src-4.8.5/include/QtGui' -I'd:/cifs/lab/temp/buildqt/qt-everywhere-opensource-src-4.8.5/include' -I'd:/ cifs/lab/temp/buildqt/qt-everywhere-opensource-src-4.8.5/include/ActiveQt' -I'release' -I'd:/cifs/lab/temp/buildqt/qt-ev erywhere-opensource-src-4.8.5/mkspecs/default' -D__GNUC__ -DWIN32 window.h -o release/moc_window.cpp g++ -c -pipe -O2 -frtti -fexceptions -mthreads -Wall -Wextra -DUNICODE -DQT_DLL -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -DQT_HAVE_MMX -DQT_HAVE_3DNOW -DQT_HAVE_SSE -DQT_HAVE_MMXEXT -DQT_HAVE_SSE2 -DQT_THREAD_SUPPORT -DQT_NEEDS_QMAIN -I'd:/ cifs/lab/temp/buildqt/qt-everywhere-opensource-src-4.8.5/include/QtCore' -I'd:/cifs/lab/temp/buildqt/qt-everywhere-opens ource-src-4.8.5/include/QtGui' -I'd:/cifs/lab/temp/buildqt/qt-everywhere-opensource-src-4.8.5/include' -I'd:/cifs/lab/te mp/buildqt/qt-everywhere-opensource-src-4.8.5/include/ActiveQt' -I'release' -I'd:/cifs/lab/temp/buildqt/qt-everywhere-op ensource-src-4.8.5/mkspecs/default' -o release/moc_window.o release/moc_window.cpp g++ -Wl,-s -mthreads -Wl,-subsystem,windows -o release/findfiles.exe release/main.o release/window.o release/moc_window. o -L'd:/cifs/lab/temp/buildqt/qt-everywhere-opensource-src-4.8.5/lib' -lmingw32 -lqtmain -lQtGui4 -lQtCore4 make[1]: Leaving directory `/d/cifs/lab/csdn/bitcoin/3rd/qt-4.8.5-mingw32-4.8.1/examples/dialogs/findfiles'
7）测试例子程序
记住复制依赖的dll到可执行例子程序目录下
执行：
问题追踪：
(1) confgure.exe和configure脚本的差别
执行sh configure -platform win32-g++ -opensource -confirm-license 会导致配置脚本去引用qmake/Makefile.unix文件，为什么？直接导致UNICODE宏没有定义，进而导致qmake/project.cpp无法编译。
#mkspecs/default is used as a (gasp!) default mkspec so QMAKESPEC needn't be set once configured
rm -rf mkspecs/default
ln -s `echo $XQMAKESPEC | sed "s,^${relpath}/mkspecs/,,"` mkspecs/default
# fix makefiles
for mkfile in GNUmakefile Makefile; do
EXTRA_LFLAGS=
EXTRA_CFLAGS=
in_mkfile="${mkfile}.in"
if [ "$mkfile" = "Makefile" ]; then
# if which qmake >/dev/null 2>&1 && [ -f qmake/qmake.pro ]; then
# (cd qmake && qmake) >/dev/null 2>&1 && continue
# fi
in_mkfile="${mkfile}.unix"
(2) 如果是在linux下用mingw32交叉编译qt
期望是编译运行在win32窗口系统上的qt，而不是x11支持的qt，但是，在linux上只能执行configure脚本，而这个脚本默认是为linux的x11编写的，
方案一（未测试）：使用configure.exe配置，CROSS_COMPILE=i686-w64-mingw32- gmake来编译
方案二（未测试）：
./configure -no-fast -no-stl -no-opengl -no-openvg -no-webkit -no-script -no-scripttools -no-declarative -nomake examples -nomake tools -nomake demos -openssl -I /root/harrywu/build/3rd/ssl/include/ -L /root/harrywu/build/3rd/ssl/lib/ -xplatform win32-g++ -device-option CROSS_COMPILE=i686-w64-mingw32- && gmake && gmake install
开始的时候，构建系统会调用本地编译器（不带前缀的g++）编译一些qmake相关的构建部件，然后开始invoke带有前缀的交叉工具链构建qt库。
