qt 5.7.0 在配置后在 cygwin 中出错
qt 5.7.0 make error in cygwin after configure
[UPDATE2] qt 5.7 在 windows 环境 (cygwin/mingw) 下交叉编译似乎有问题。 qt 5.5交叉编译比较容易
我正在使用我在 cygwin 上用 crosstool-ng 生成的工具链将 qt 5.7.0 交叉编译到 raspberry pi 上的 armv7 linux 目标。
主机：cygwin
工具链：armv7-rpi2-linux-gnueabihf（通过 crosstool-ng 生成）
目标：armv7 linux
我下载并提取了 qt 5.7.0 tarball，并从 cygwin shell 中将其提取到 cygwin 目录结构下（即我没有使用 winzip/7zip 提取文件）。
配置命令：
~/qtpi]$ ./configure -prefix /cygdrive/c/qt5pi -debug-and-release -no-accessibility -device
linux-rpi3-g++ -opensource -confirm-license -make libs -platform cygwin-g++
-device-option CROSS_COMPILE=/cygdrive/c/cygwin64/home/admin/x-tools/armv7-rpi2-linux-gnueabihf/bin/armv7-rpi2-linux-gnueabihf-
-sysroot /cygdrive/c/cygwin64/home/admin/x-tools/armv7-rpi2-linux-gnueabihf/armv7-rpi2-linux-gnueabihf/sysroot -v
配置完成如下...
...
...
xkbcommon-x11........... no
xkbcommon-evdev......... no
zlib ................... yes (bundled copy)
NOTE: Qt is using double for qreal on this system. This is binary
incompatible against Qt 5.1. Configure with '-qreal float' to create a build
that is binary compatible with 5.1.
Qt is now configured for building. Just run 'make'. Once everything is
built, you must run 'make install'. Qt will be installed into
/cygdrive/c/qt5pi
Prior to reconfiguration, make sure you remove any leftovers from the
previous build.
此时运行 make报错如下：
~/qtpi]$ make
cd qtbase/ && ( test -e Makefile || /home/admin/qtpi/qtbase/bin/qmake /home/admin/qtpi/qtbase/qtbase.pro -qtconf /home/admin/qtpi/qtbase/bin/qt.conf -o Makefile ) && /usr/bin/make -f Makefile
make[1]: Entering directory '/home/admin/qtpi/qtbase'
/bin/sh: -c: line 1: syntax error: unexpected end of file
make[1]: *** [Makefile:43: sub-src-make_first] Error 1
make[1]: Leaving directory '/home/admin/qtpi/qtbase'
make: *** [Makefile:78: module-qtbase-make_first] Error 2
卡在这里半天了。据我所知，这似乎与 dos-unix 行结尾或 mingw shell（我也通过 mingw 得到同样的错误）
[UPDATE1] 这里是 /home/admin/qtpi/qtbase/Makefile 的前 200 多行供参考。

请帮我解决这个问题！
https://forum.qt.io/topic/69482/cannot-compile-qmake-for-win32-g-cross-compiling
在这个来自 qt 支持论坛的 link 中，看起来 qt 5.7 在 windows 上编译它有一些问题。
我正在使用没有问题的 5.5 版本
根据@Torugobeck 指出的cannot-compile-qmake-for-win32-g-cross-compiling，我尝试交叉编译Qt5.5，它似乎已经走过场并在Cygwin下完成了'make'和'make install' -但是使用 cygwin-g++ 平台（而不是 mingw 下的 win32-g++ 平台选项）
配置在 above link 中概述的 2 个阶段中成功。
从这个配置命令开始：
./configure -prefix /cygdrive/c/qtpi5 -debug-and-release -no-accessibility
-opensource -confirm-license -make libs -platform cygwin-g++
-device linux-rasp-pi2-g++ -sysroot /cygdrive/c/cygwin64/home/admin/x-tools/armv7-rpi2-linux-gnueabihf/armv7-rpi2-linux-gnueabihf/sysroot -v
这成功为 windows 生成了 qmake 二进制文件。
然后按照 above link 中所述编辑 /qtbase/configure 文件。
继续此配置命令：
./configure -prefix /cygdrive/c/qtpi5 -debug-and-release -no-accessibility
-opensource -confirm-license -make libs -platform cygwin-g++
-device linux-rasp-pi2-g++ -sysroot /cygdrive/c/cygwin64/home/admin/x-tools/armv7-rpi2-linux-gnueabihf/armv7-rpi2-linux-gnueabihf/sysroot
-v -device-option CROSS_COMPILE=/cygdrive/c/cygwin64/home/admin/x-tools/armv7-rpi2-linux-gnueabihf/bin/armv7-rpi2-linux-gnueabihf-
函数 /home/admin/qtpi/qtbase/src/corelib/global/qglobal.cpp:determineWinOsVersionPost8 windows 与版本检测相关的故障
我强制函数 return 为真并在输出参数上填写相关 OS 版本信息。
此配置完成后。 'make' 只用了 4 小时就完成了，没有出现错误 - 接下来 'make install' 也是如此。
我编译了一个最小的 GUI 程序 qith qt5 并且能够在目标 - raspberry 上执行它 PI/arm7-linux。
简而言之，cygwin 能够使用 .
成功地交叉编译 qt 5.5
p.s GUI 可执行文件无法启动 GUI，似乎只是挂在那里并显示以下警告...
libEGL warning: DRI2: failed to authenticate
我正在调查此事。
[UPDATE2] qt 5.7 在 windows 环境 (cygwin/mingw) 下交叉编译似乎有问题。 qt 5.5交叉编译比较容易
我正在使用我在 cygwin 上用 crosstool-ng 生成的工具链将 qt 5.7.0 交叉编译到 raspberry pi 上的 armv7 linux 目标。
主机：cygwin 工具链：armv7-rpi2-linux-gnueabihf（通过 crosstool-ng 生成） 目标：armv7 linux
我下载并提取了 qt 5.7.0 tarball，并从 cygwin shell 中将其提取到 cygwin 目录结构下（即我没有使用 winzip/7zip 提取文件）。
配置命令：
~/qtpi]$ ./configure -prefix /cygdrive/c/qt5pi -debug-and-release -no-accessibility -device
linux-rpi3-g++ -opensource -confirm-license -make libs -platform cygwin-g++
-device-option CROSS_COMPILE=/cygdrive/c/cygwin64/home/admin/x-tools/armv7-rpi2-linux-gnueabihf/bin/armv7-rpi2-linux-gnueabihf-
-sysroot /cygdrive/c/cygwin64/home/admin/x-tools/armv7-rpi2-linux-gnueabihf/armv7-rpi2-linux-gnueabihf/sysroot -v
配置完成如下...
...
...
xkbcommon-x11........... no
xkbcommon-evdev......... no
zlib ................... yes (bundled copy)
NOTE: Qt is using double for qreal on this system. This is binary
incompatible against Qt 5.1. Configure with '-qreal float' to create a build
that is binary compatible with 5.1.
Qt is now configured for building. Just run 'make'. Once everything is
built, you must run 'make install'. Qt will be installed into
/cygdrive/c/qt5pi
Prior to reconfiguration, make sure you remove any leftovers from the
previous build.
此时运行 make报错如下：
~/qtpi]$ make
cd qtbase/ && ( test -e Makefile || /home/admin/qtpi/qtbase/bin/qmake /home/admin/qtpi/qtbase/qtbase.pro -qtconf /home/admin/qtpi/qtbase/bin/qt.conf -o Makefile ) && /usr/bin/make -f Makefile
make[1]: Entering directory '/home/admin/qtpi/qtbase'
/bin/sh: -c: line 1: syntax error: unexpected end of file
make[1]: *** [Makefile:43: sub-src-make_first] Error 1
make[1]: Leaving directory '/home/admin/qtpi/qtbase'
make: *** [Makefile:78: module-qtbase-make_first] Error 2
卡在这里半天了。据我所知，这似乎与 dos-unix 行结尾或 mingw shell（我也通过 mingw 得到同样的错误）

请帮我解决这个问题！
https://forum.qt.io/topic/69482/cannot-compile-qmake-for-win32-g-cross-compiling
在这个来自 qt 支持论坛的 link 中，看起来 qt 5.7 在 windows 上编译它有一些问题。 我正在使用没有问题的 5.5 版本
根据@Torugobeck 指出的cannot-compile-qmake-for-win32-g-cross-compiling，我尝试交叉编译Qt5.5，它似乎已经走过场并在Cygwin下完成了'make'和'make install' -但是使用 cygwin-g++ 平台（而不是 mingw 下的 win32-g++ 平台选项）
配置在 above link 中概述的 2 个阶段中成功。
从这个配置命令开始：
./configure -prefix /cygdrive/c/qtpi5 -debug-and-release -no-accessibility
-opensource -confirm-license -make libs -platform cygwin-g++
-device linux-rasp-pi2-g++ -sysroot /cygdrive/c/cygwin64/home/admin/x-tools/armv7-rpi2-linux-gnueabihf/armv7-rpi2-linux-gnueabihf/sysroot -v
这成功为 windows 生成了 qmake 二进制文件。
然后按照 above link 中所述编辑 /qtbase/configure 文件。
继续此配置命令：
./configure -prefix /cygdrive/c/qtpi5 -debug-and-release -no-accessibility
-opensource -confirm-license -make libs -platform cygwin-g++
-device linux-rasp-pi2-g++ -sysroot /cygdrive/c/cygwin64/home/admin/x-tools/armv7-rpi2-linux-gnueabihf/armv7-rpi2-linux-gnueabihf/sysroot
-v -device-option CROSS_COMPILE=/cygdrive/c/cygwin64/home/admin/x-tools/armv7-rpi2-linux-gnueabihf/bin/armv7-rpi2-linux-gnueabihf-
函数 /home/admin/qtpi/qtbase/src/corelib/global/qglobal.cpp:determineWinOsVersionPost8 windows 与版本检测相关的故障
我强制函数 return 为真并在输出参数上填写相关 OS 版本信息。
此配置完成后。 'make' 只用了 4 小时就完成了，没有出现错误 - 接下来 'make install' 也是如此。
我编译了一个最小的 GUI 程序 qith qt5 并且能够在目标 - raspberry 上执行它 PI/arm7-linux。
简而言之，cygwin 能够使用
p.s GUI 可执行文件无法启动 GUI，似乎只是挂在那里并显示以下警告...
libEGL warning: DRI2: failed to authenticate
我正在调查此事。
