Stopped in routine FPX: SIG_HANDLER
时间: 2024-06-07 21:06:51 浏览: 20
这个错误通常出现在嵌入式系统或者类似的环境中,它是由于程序收到了一个未处理的信号而导致的。SIG_HANDLER是信号处理程序的缩写,这个问题表示程序在执行信号处理程序时出现了问题。可能的原因包括信号处理程序的逻辑错误、内存泄漏或者其他错误。要解决这个问题,你需要检查信号处理程序的代码,确保它没有逻辑错误,并且不会导致内存泄漏。你还应该检查程序的其他部分,以查找可能导致信号处理程序出错的其他原因。

这是一个链接错误,编译器找不到 curl 库的函数。你需要在链接时加上 curl 库。如果你使用的是 CMake,可以在 CMakeLists.txt 中添加以下代码:
```
find_package(CURL REQUIRED)
target_link_libraries(YourProjectName ${CURL_LIBRARIES})
```
其中,YourProjectName 是你的项目名称。
QObject::~QObject: Timers cannot be stopped from another thread terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc terminate called recursively
这个错误信息可能涉及到两个问题:
1. QObject被在另一个线程中删除,但其中的计时器没有在其所属线程中停止。这可能会导致无法预料的行为和错误,因为计时器仍在运行,即使QObject已经被销毁。
解决方案是确保QObject所属的线程和删除它的线程是同一线程,并在删除QObject之前,停止其中的计时器。
2. 错误信息中还包含了std::bad_alloc异常,这表明内存分配失败,导致程序崩溃。
解决方案是检查程序是否有内存泄漏或者是否需要优化内存使用。如果程序需要分配大量内存,可以考虑使用内存池等技术来优化内存使用。如果程序存在内存泄漏,可以使用内存检测工具来帮助找出问题并解决。
