I am using gdb version 6.8 on an ubuntu 9 machine image. I would like to update it to the latest one (7.8?) but I'm not sure how to do it.

我尝试按照此处的说明 https://askubuntu.com/questions/529781/upgrade-from-gdb-7-7-to-7-8 ，但它们不起作用.

I tried following the instructions here https://askubuntu.com/questions/529781/upgrade-from-gdb-7-7-to-7-8 but they didn't work.

它在tar命令处停了下来，并说这看起来不像tar文件"

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

任何人都可以帮忙吗?

推荐答案

这只是一个猜测，但是您的tar版本可能太旧了，可能不支持xz压缩方案.您引用的链接建议下载gdb-7.8.tar.xz，您可以尝试运行unxz gdb-7.8.tar.xz，它将把文件解压缩为gdb-7.8.tar，然后可以重试tar -xf gdb-7.8.tar，现在应该可以了.

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，您可以尝试下载此文件，而不是http://ftp.gnu.org/gnu/gdb/gdb-7.8.2.tar.gz，相比以前使用的是7.8，这是7.8.2版本，并且包含一些小错误修复，但是，此文件使用gzip压缩方案， tar中支持的时间超过xz，因此此新文件应使用tar -xf gdb-7.8.2.tar.gz提取.

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，然后直接转到7.10(

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.
