我有这个C代码运行正常，直到将我的系统升级到Scientific Linux 6.它有一些OpenGL的东西，它用gcc编译这些选项
-lncurses -lX11 -lGL -lm -g
然后它会出现故障。关注this post我得到了这个

我尝试了debuginfo安装，但收到了这条消息：
No debuginfo packages available to install
答案 0 :(得分：1)
尝试使用gdb实际运行程序，而不仅仅是加载核心文件。它可能会更有帮助。您也可以尝试使用valgrind来运行它：它是内存调试的绝佳工具。即使没有debuginfo，您也可以找到源文件中的哪一行触发崩溃。
确保在启用调试（gcc -ggdb）的情况下编译程序。
答案 1 :(得分：1)
从命令行输入以下命令：
gdb [program name]
这将打开gdb调试器。
run [command line arguments]
现在该程序将出现故障。
backtrace
这将显示程序崩溃的位置。
