原生构建qt5.7.1 on raspberry pi获取错误：/usr/lib/arm-linux-gnueabihf/libQt5Quick.so.5：未定义引用`QV8Engine :: toVariant

标签： qt raspberry-pi

我试图按照这条指令在pi3上构建qt 5.7.1： https://wiki.qt.io/Native_Build_of_Qt_5.4.1_on_a_Raspberry_Pi

我使用的源包是： QT-无处不开源-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

该指令正在使用＆＃34; linux-rasp-pi-g ++＆＃34;，但我认为它应该是rpi3的linux-rpi3-g ++。

制作，我得到的错误如下：

那么，我该如何解决这个问题？

感谢。

答案 0 :(得分：4)

我已经解决了这个问题，现在又出现了一个新问题。

在pi上本地构建qt之前，我安装了qt： sudo apt-get install qt5-default，以及其他qt5包。

虽然我有：   sudo apt-get删除那些包，它可能仍然有效。

所以我格式化了SD卡并重新烧毁了Raspbian图像，按照说明进行了操作，＃34; make＆＃34;，问题就消失了。

但现在我有另一个问题。

当我＆＃34; make install＆＃34;时，我收到此错误：

我发现qtlocation / src / 3rdparty

中有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。

我检查了构建日志，看来在directoriy qtlocation / src / 3rdparty中的cpp文件没有编译，
