[Error] no matching function for call to 'lower_bound(int)'
时间: 2024-04-20 07:25:03 浏览: 11
这个错误提示意味着在你的代码中,没有找到匹配的函数来调用 `lower_bound(int)`。`lower_bound()` 是一个 STL 算法函数,用于在有序容器中查找第一个不小于给定值的元素的位置。它通常用于向有序容器插入新元素或者进行查找操作。
可能的原因是你没有包含正确的头文件或者使用了错误的参数类型。请确保你包含了 `<algorithm>` 头文件,并且传递给 `lower_bound()` 函数的参数类型与容器中的元素类型匹配。
如果你能提供更多的代码细节,我可以帮助你更具体地解决这个问题。

no matching function for call to 'pthread_create'
It seems that you are encountering an error related to the function call 'pthread_create'. This error typically occurs when the compiler cannot find a suitable function with the provided arguments.
To resolve this issue, you need to make sure that you have included the necessary header file for pthreads in your code. You can include the pthread.h header file using the directive:
```c
#include <pthread.h>
```
Additionally, ensure that you are passing the correct arguments to the pthread_create function. The function requires four parameters: a pointer to a pthread_t variable, a pointer to a pthread_attr_t structure (can be set to NULL for default attributes), a function pointer to the thread routine, and an optional argument to be passed to the thread routine.
Here's an example of how you can use pthread_create:
```c
#include <pthread.h>
void* myThread(void* arg) {
// Thread logic goes here
return NULL;
}
int main() {
pthread_t thread;
pthread_create(&thread, NULL, myThread, NULL);
// Other main thread logic
pthread_join(thread, NULL);
return 0;
}
```
Make sure to replace "myThread" with the name of your thread function and customize it according to your needs.
If you're still facing issues, please provide more details about your code and the specific error message so that I can assist you further.
