linux - qt 5.7.0 在配置后在 cygwin 中出错

Question

[UPDATE2] qt 5.7 在 windows 环境下(cygwin/mingw)交叉编译似乎有问题。 qt 5.5可以相对容易地交叉编译。

我正在使用我在 cygwin 上使用 crosstool-ng 生成的工具链将 qt 5.7.0 交叉编译到树莓派上的 armv7 linux 目标。

主机:cygwin 工具链:armv7-rpi2-linux-gnueabihf(通过 crosstool-ng 生成) 目标:armv7 linux

我下载并解压了 qt 5.7.0 tarball，并从 cygwin shell 中将其解压到 cygwin 目录结构下(即我没有使用 winzip/7zip 来解压文件)。

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

我在这里卡了半天。据我所知，这似乎与 dos-unix 行结尾或 mingw shell 无关(我也通过 mingw 得到同样的错误)

[UPDATE1] 这里是/home/admin/qtpi/qtbase/Makefile 的前 200 多行供引用。

在 qt 支持论坛的这个链接中，看起来 qt 5.7 在 windows 上编译它有一些问题。 我用的是5.5版本没问题
