valgrind: ./cache1.c: Permission denied

As an AI language model, I cannot access your file system or execute any commands on your local machine. However, I can provide you with some general information about this error message.

This error message indicates that Valgrind, a memory debugging tool, does not have permission to access the file cache1.c. This could be due to several reasons:

- The file may not exist in the specified directory.
- The file may be owned by another user, and Valgrind does not have permission to read or execute it.
- The file may be marked as read-only or executable only by the owner.

To resolve this issue, you can try the following:

- Check if the file exists in the specified directory.
- Ensure that Valgrind has permission to access the file. You can use the chmod command to change the file permissions.
- Run Valgrind as the owner of the file or with sudo privileges.

If the issue persists, you can try running Valgrind on another file or directory to verify if it is a permissions issue or a problem with Valgrind itself.

valgrind: failed to start tool 'memcheck' for platform 'arm-linux': No such file or directory

这个错误通常是由于在 ARM 平台上缺少 Valgrind 的 memcheck 工具所导致的。您需要检查您的系统是否支持 Valgrind，并安装适合您的系统的版本。

如果您已经安装了 Valgrind，那么可能是您的路径设置不正确。您可以尝试重新安装 Valgrind，并确保将其添加到 PATH 环境变量中。

另外，如果您正在使用交叉编译，您需要使用相应的交叉编译版本的 Valgrind。您可以从 Valgrind 官方网站获取适合您系统的版本。
