解决GDB调试中缺失 glibc-debuginfo 的错误提示

beyes

Linux 发行版：OpenSuse 12.2

在用 gdb 调试程序时，发现

Missing separate debuginfos, use: zypper install glibc-debuginfo-2.15-22.6.4.i686

这样的错误提示。

实际上，别的发行版也可能类似发现，记得在 Fedora 上也曾遇见。这是因为没有安装 glibc-debuginfo 这个包，而该包又不在正式的默认源中，因此可按下面步骤进行安装：

beyes:/home/beyes # zypper modifyrepo --enable repo-debug
Repository 'repo-debug' has been successfully enabled.
beyes:/home/beyes # zypper refresh

安装完后，再次调试时就不会出现该上面的错误提示。
