gdb7.6没有可识别格式的核心文件处理程序

当我使用gdb7.6分析CORE文件时，gdb打印以下错误：

“/core:没有核心文件处理程序识别格式”

我的环境：

• HP-UX hp12161 B.11.31 U ia64 0546304299
• 编译器：gcc4.7.2
• gdb7.6 Configure=./Configure--enable-64位bfd

我注意到在ia64 hpux平台中，gdb不从_core_部分调用set_gdbarch_regset_，不推荐使用的_add_core_fns接口

如何解决此问题？

您应该使用。这是HPE在hp ux上工作的GNU gdb分支。GNU gdb不适用于hp ux，也不适用于使用hp ux aCC构建的可执行文件，也不适用于使用gcc构建的可执行文件

例如，对于此系统上可用的任何版本的gdb：

[ 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)

在上面运行GNUGDB，我可以重现您面临的问题

[ hp-ux_ia64 ~ ] $ /usr/local/bin/gdb -c core
