[当我使用gdb7.6分析核心文件时，gdb打印以下错误：
“ ./ core：没有核心文件处理程序可识别格式”
我的环境：
[我注意到在ia64-hpux平台中gdb不会调用set_gdbarch_regset_from_core_section，deprecated_add_core_fns接口。
我应该如何解决此问题？
您应该使用HPE Wildebeest Debugger。这是HPE在hp-ux上运行的GNU gdb的分支。 GNU gdb在hp-ux上不起作用，在用hp-ux aCC生成的可执行文件或用gcc生成的可执行文件上均不起作用。
例如，使用此系统上可用的任何gdb版本：
[ hp-ux_ia64 ~ ] $ gcc --version
gcc (GCC) 4.7.1

我制作了一个程序转储核心：
[ hp-ux_ia64 ~ ] $ cat > 1.c
main () { ((int*)0)[0]=1; }
[ hp-ux_ia64 ~ ] $ gcc 1.c
[ hp-ux_ia64 ~ ] $ ./a.out
Segmentation fault (core dumped)
正在运行GNU gdb，我可以重现您遇到的问题。
[ hp-ux_ia64 ~ ] $ /usr/local/bin/gdb -c core

HPE gdb给了我适当的堆栈跟踪。
