【中文标题】在树莓派上原生构建 qt5.7.1 得到错误：/usr/lib/arm-linux-gnueabihf/libQt5Quick.so.5: 未定义对 `QV8Engine::toVariant 的引用

【英文标题】：native build qt5.7.1 on raspberry pi get errors: /usr/lib/arm-linux-gnueabihf/libQt5Quick.so.5: undefined reference to `QV8Engine::toVariant

【问题描述】：

我尝试按照以下说明在 pi3 上构建 qt 5.7.1： https://wiki.qt.io/Native_Build_of_Qt_5.4.1_on_a_Raspberry_Pi

我使用的源码包是： qt-everywhere-opensource-src-5.7.1.tar

配置为：

./configure -v -opengl es2 -force-pkg-config -device linux-rpi3-g++ -device-option CROSS_COMPILE=/usr/bin/ -opensource -confirm-license -optimized-qmake -reduce-exports - release -qt-pcre -qt-xcb -make libs -no-use-gold-linker -prefix /usr/local/qt5

指令使用“linux-rasp-pi-g++”，但我认为Rpi3应该是linux-rpi3-g++。

制作，我收到如下错误：

那么，我该如何解决这个问题？

谢谢。

【参考方案1】：

这个问题我已经解决了，现在又有新问题了。

在 pi 上原生构建 qt 之前，我通过以下方式安装了 qt： sudo apt-get install qt5-default 和其他 qt5 软件包。

虽然我有： sudo apt-get 删除这些软件包，它可能仍然有效。

所以我格式化了 SD 卡并重新刻录了一个 Raspbian 映像，按照说明“制作”，问题就消失了。

但现在我有另一个问题。

当我“make install”时，我得到这个错误：

我发现qtlocation/src/3rdparty里面有3个目录

clip2tri
clipper
poly2tri

和 qtlocation/lib 中的 3 个文件：

libclip2tri.prl
libclipper.prl
libpoly2tri.prl

但没有 lib 文件。

我查看了构建日志，qtlocation/src/3rdparty目录下的cpp文件似乎没有编译，

【讨论】：

您是从源代码构建 Qt 还是使用 raspbian 附带的软件包？

我在 RH6.5 上构建 Qt-5.9.1 时看到了同样的问题。对于 3 个缺失的库，我去了那些目录并手动运行 make。之后一切顺利。
