c++ - 如何在archlinux上安装旧的QT版本？

问题描述

我很久以前就安装了 pacman 的 QT5。

qmake -v          
QMake version 3.1
Using Qt version 5.15.2 in /usr/lib

我想安装 QT 5.5.1，所以我下载了qt-everywhere-opensource-src-5.5.1.7z并按照自述文件进行操作。这是最终结果：

make[3]: *** [Makefile:21908: .obj/qsslcertificate_openssl.o] Error 1
make[3]: Leaving directory '/home/chippy/Downloads/qt-everywhere-opensource-src-5.5.1/qtbase/src/network'
make[2]: *** [Makefile:192: sub-network-make_first] Error 2
make[2]: Leaving directory '/home/chippy/Downloads/qt-everywhere-opensource-src-5.5.1/qtbase/src'
make[1]: *** [Makefile:46: sub-src-make_first] Error 2
make[1]: Leaving directory '/home/chippy/Downloads/qt-everywhere-opensource-src-5.5.1/qtbase'
make: *** [Makefile:73: module-qtbase-make_first] Error 2

然后我下载了 qt-opensource-linux-x64-5.5.1.run在 shell 上运行：

$ ./qt-opensource-linux-x64-5.5.1.run

我无法理解错误，我不知道这是否是解决问题的正确方法。

解决方案

删除以前的 qt，然后安装一个新的 . 请参阅有关删除 Qt的信息

您应该转到安装 Qt 的路径，然后运行维护工具.exe 文件。然后卸载以前的，安装新的。
