我现在有点困了。我最近一直在做C++项目，但是我遇到了异常。目标是STM32。我使用STs Cube MX代码生成器设置了2个项目。执行的代码是

try
    {
        throw 1;
    }
    catch(const int& ex)
    {
        configASSERT(0);
    }

我使用的IDE（SW4STM32，基于eclipse，g++）无法捕获异常。我总是遇到终止处理程序。另一个IDE（AtolicTrueStudio，基于eclipse的，g++）捕获异常

因此，这不是一个目标问题，而是一个IDE问题。我已经从g++编译器和链接器选项中删除了fno异常。但还是没有运气。关于去哪里找，你还有其他想法吗

Thx:）

现在，正如您所看到的，没有FNOException处于活动状态。因此，我希望收到例外情况：(

SW4STM32使用Eclipse平台4.6.3 Eclipse CDT 9.2.1 Attolic使用Eclipse平台4.6.1、Eclipse CDT 9.1.0

所以eclipse的基本版本非常相似。

你有其他的想法吗？< /P>这是一个有很多可能性的大帐篷。我建议把Eclipse版本、CDT版本、GDB版本和GCC版本添加到这个问题中。我不认为这是IDE问题。检查编译器标志。C++异常是非常昂贵的，而且在嵌入式开发中不经常使用。编辑我的第一篇帖子。请看一看：）
