Re: runtime identification of compiler through executable

i need to use this information in a source file ...

Now, you can tell what an executable has been linked against
by using "dump -H" or ("dump -n" for alot of verbose output
including symbols in libraries that are referenced)

You can also tell what source files have been used for an
executable (If they followed the sccs file format) by using "what"

Hope this helps,

You can try a couple of things, but I am not sure it will give you
exactly what you are looking for:

The "file" command will tell you if a program is executable, but does
not give you the specifics such as indicating that the exceutable was
written in C or Perl or Korn or whatever.

You could try the "strings" command, which may help. It sometimes list
the compiler at the top, or the libraries used.

For example, the first ten lines of this "kornsample" script shows it
was compiled using a package called Shell-Lock (It is a Korn Shell
script):

# strings kornsample|head
H: Too many args
: No read permission
awk
@(#)shell-lock
1.6.2.2
?BBOF
KTYPPa
+40;3?
9;4/|^|
j^o89&o.)00


In the "csample" program below, you can see a library "threads_init.c"
and its original path. This suggests it was a C source, and the path
may suggest whether Visual Age or some other C compiler was used.

# strings csample |head
@(#)61
1.14 src/bos/usr/ccs/lib/libc/__threads_init.c, libcthrd, bos510
