Qt6交叉编译STM32MP157 perl错误

Question

我正在为Qt6 STM32MP157构建

Qt源代码下载v6.1.2平台:Ubuntu18.04.5LTS STM32 SDK版本: v2.0.0

对于主机来说，同样的构建成功了(生成qt主机工具)，但是当我使用用于stm32mp157的工具链文件运行它时，syncqt.pl第55行的perl出错了：

use English qw(-no_match_vars );

错误消息如下：

它无法加载English.pm

我注意到perl在为stm编译时使用了不同的版本。因此，构建系统使用SDK中的perl。而且STM没有English.pm。

我的问题是我们如何从主机系统中使用perl？

Answer 1

是我的错。在我的工具链文件中，我重写了"CMAKE_PROGRAM_PATH“来查找SDK编译器和其他程序，我不得不调整它，以便它能够从主机系统中找到perl。
