以下详细信息来自运行Solaris 10的Sun计算机中的会话。

$ file devli

为什么gdb不能识别devli的文件格式的任何细节？我在互联网上搜索但找不到与此特定问题相关的任何内容。任何指针都会有所帮助。

a.c进入使用gcc构建的a; devli使用Sun ONE Studio 8。

Answer 1

请注意，GDB 6.4是4岁。使用（当前）GDB 7.0可能会更好运。

devli可执行文件也可能已损坏（file只查看可执行文件的前几个字节，但GDB需要更多的文件内容为自我-consistent）。 readelf --all > /dev/null是否会报告任何警告？

Solaris 10上的GNU gdb 6.4无法识别文件格式
