这错误提示是因为在你的代码中,已经有一个名为 "PushVehTypeSideData" 的 C 函数被声明了,但是在包含 "VehPlateCommon.h" 头文件时,又重新声明了一个同名的函数。这样就会产生函数冲突的问题。
解决方法是将头文件中的函数声明改为 static 或者使用命名空间来避免函数名冲突。比如:
```cpp
namespace VehPlateCommon {
extern "C" static int PushVehTypeSideData(void *handle, vel_side_data *s_data);//推送入车身数据,返回0,接收成功;返回1,数据异常,接收失败
}
```
这样就可以避免函数名冲突的问题了。

error: conflicting declaration of C function
这个错误通常是因为在代码中存在重复定义的函数声明。可能是在头文件中定义了函数,但在源文件中也定义了同名的函数,导致编译器无法判断该使用哪个定义。
解决方法是检查代码中是否存在重复定义的函数声明,如果有的话,需要将其中一个删除或重命名。也可以考虑使用头文件保护宏来防止头文件被重复包含,从而避免重复定义函数的问题。
Module build failed (from ../node_modules/cache-loader/dist/cjs.js):
As an AI language model, I cannot see the exact error message that caused the build failure. However, this error message typically occurs when there is an issue with the cache-loader module. The cache-loader module is used to cache the output of expensive webpack loaders so that subsequent builds can be faster.
Here are some possible solutions you can try:
1. Delete the node_modules folder and reinstall all dependencies: This will remove any cached files and ensure that all dependencies are up-to-date.
2. Clear the cache-loader cache: Run the command `npm run clearCache` to clear the cache.
3. Upgrade to the latest version of cache-loader: Run the command `npm install cache-loader@latest --save-dev` to upgrade to the latest version of the module.
4. Check for conflicting modules: Ensure that there are no conflicting modules that may be causing the build failure. You can check for conflicting modules by running the command `npm ls` to see a list of all installed modules and their dependencies.
5. Check your webpack configuration: Ensure that your webpack configuration is correct and that all required loaders are properly configured.
If none of the above solutions work, you may need to provide more information about the error message or seek help from the webpack community.
