它停在 tar 命令处并说这看起来不是 tar 文件"

It stopped at the tar command and said "this does not look a tar file"

推荐答案

这只是一个猜测，但可能是你的 tar 版本太旧，不支持 xz压缩方案.您参考的链接建议下载gdb-7.8.tar.xz，您可以尝试运行unxz gdb-7.8.tar.xz，它将文件解压缩为gdb-7.8.tar，然后您可以重试 tar -xf gdb-7.8.tar 现在应该可以工作了.

This is just a guess, but it might be the case that your version of tar is so old it does not support the xz compression scheme. The link you reference suggests downloading gdb-7.8.tar.xz, you can try running unxz gdb-7.8.tar.xz which will uncompress the file into gdb-7.8.tar, you can then retry tar -xf gdb-7.8.tar which should now work.

或者你可以尝试下载这个文件而不是 http://ftp.gnu.org/gnu/gdb/gdb-7.8.2.tar.gz，这是 7.8.2 版本比较对于您之前使用的 7.8，因此包含一些小错误修复，但是，此文件使用 gzip 压缩方案，该方案在 tar 中的支持时间比 xz 长，这个新文件应该可以使用 tar 很好地提取 -xf gdb-7.8.2.tar.gz.

Alternatively you could try downloading this file instead http://ftp.gnu.org/gnu/gdb/gdb-7.8.2.tar.gz, this is the 7.8.2 release compared to the 7.8 you were using before, and so contains a few minor bug fixes, however, this file uses the gzip compression scheme, which has been supported in tar for longer than xz, this new file should extract fine with tar -xf gdb-7.8.2.tar.gz.

最后，您可能有兴趣完全跳过 7.8，直接进入 7.10 (http://ftp.gnu.org/gnu/gdb/gdb-7.10.tar.gz)，因为这应该包含更多令人兴奋的新功能和改进.

Finally, you might be interested in skipping 7.8 completely, and moving straight to 7.10 (http://ftp.gnu.org/gnu/gdb/gdb-7.10.tar.gz) as this should contain even more exciting new features and improvements.
