无法在 Raspberry Pi 3 B+ 上交叉编译 Qt5.11.1

Question

我无法获得 Qt5.11.1 交叉编译...我尝试了不同的解决方案，例如：

• https://lb.raspberrypi.org/forums/viewtopic.php?t=204529
• https://wiki.qt.io/index.php?title=Raspberrypi_beginners_guide&redirect=no

我的操作系统是 manjaro，而 raspberry 是 raspbian。

这是我的配置命令：

./Src/configure -opengl es2 -device linux-rasp-pi3-vc4-g++ -device-option CROSS_COMPILE=arm-linux-gnueabihf- -sysroot /run/media/luca/rootfs -opensource -confirm-license -optimized-qmake -reduce-exports -release -skip qtwebengine -skip qtscript -nomake examples -make libs -prefix /usr/local/qt5 -v -no-use-gold-linker -nomake tests -no-compile-examples -no-pch -eglfs -skip qtwaylan

这是输出：

有人知道问题吗？？

Answer 1

from /home/luca/Dev/Qt/5.11.1/Src/qtbase/src/network/ssl/ qsslsocket_openssl11 .cpp:59:

您似乎缺少 openSSL 库。 如果您可以在没有 openSSL 的情况下生活，请使用-no-openssl 进行配置，或者尝试将其安装到您的sysroot并尝试使用-openssl-runtime 。

Answer 2

我遇到过同样的问题。 问题是Qt找不到libdl.so为了解决这个问题，我将libdl.so放在/ sysroot /usr/lib 中。

为了找到它，我将-feature-library标志添加到./configure 。 我使用的那个命令：

./configure -release -opengl es2 -device linux-rasp-pi3-g++ -device-option CROSS_COMPILE=armv8-rpi3-linux-gnueabihf- -sysroot /mnt/second/proj/dai/env/work/sysroot -opensource -confirm-license -make libs -nomake examples -nomake tests -prefix /usr/local/qt5pi -extprefix /mnt/second/proj/dai/env/work/qt5pi -hostprefix /mnt/second/proj/dai/env/work/qt5 -v -no-use-gold-linker -sql-mysql -mysql_config /mnt/second/proj/dai/env/work/../mysql_config -ssl -openssl-runtime -feature-library
