为小猎板构建嵌入式 QT5

Question

我在构建用于beagleboard的嵌入式QT5时遇到一些错误

1. QT 配置./configure -前缀/home/nirvana/ti-sdk-beagleboard-06.00.00.00/qt-everywhere-opensource-src-5.4.0-master/out -release -opensource -platform linux-g++-32 -xplatform qws/linux-TIarmv7-sgx-g++ -no-pch -no-glib -no-cups -no-nis -no-gtkstyle -opengl es2 -confirm-license-no-xcb -no-wayland -no-glib -verbose -eglfs -no-c++11 -no-accessibility -system-zlib -qt-libpng -qt-libjpeg -no-openvg -widgets -no-tslib -make libs -make tools -device-option CROSS_COMPILE=/home/nirvana/ti-sdk-beagleboard-06.00.00.00/linux-devkit/sysroots/i686-arago-linux/usr/bin/arm-linux-gnueabihf-

2.质量检查导出 QMAKESPEC=">

3. 使 -j4

有什么理想吗？

我修复了这个问题，只是强制Qt编译ARM处理器的"neon"支持，只需修改"qtbase/mkspecs/qmodule.pri"中的以下行"./configure"之后：

host_build {
    QT_CPU_FEATURES.i386 =
} else {
    QT_CPU_FEATURES.arm = neon
}
