How to get the compiler version from a binary ?

[chenn_1]

Do we have any easy we to get the original compiler information of a binary, on HPUX IA/PA machine ?

2C:
I tried copying the binary from hp-ux to linux and doing readelf. It was able to give me OS/ABI

# readelf -a tar|more
ELF Header:
Magic: 7f 45 4c 46 01 02 01 01 01 00 00 00 00 00 00 00
Class: ELF32
Data: 2's complement, big endian
Version: 1 (current)
OS/ABI: UNIX - HP-UX
ABI Version: 1
Type: EXEC (Executable file)
Machine: Intel IA-64
Version: 0x1

I am sure others will post the proper answer soon...

You can use footprints(1) to give you a summary.
Otherwise for PA32 you can use: odump -comp
For Integrity or PA64 you can use: elfdump -dc
