Re: object code from which compiler

Hi All,

given an object file is there any way (or tool) to determine which
compiler created it ?

The format of the object file may be different for each implementation or platform. Some do record the compiler name, some don't. One of my object files has the following string embedded, which I extracted with the "strings" and "grep" commands.

$ strings RGBColour.obj | grep compiler
@-compiler:"C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\bin\c2.dll"

Just determining the file format may help. Try the "file" command.

$ file devcpp/main.o
devcpp/main.o: 80386 COFF executable not stripped - version 30821

$ file linux2/main.o
linux2/main.o: ELF 32-bit LSB relocatable, Intel 80386, version 1 (SYSV), not stripped

$ file vsnet/main.obj
vsnet/main.obj: data

It recognised the Windows and Linux object files produced by GCC, but unfortunately it didn't recognise the VS.NET object file.
