how to know the compiler/link options used on a library ?

[Laurent Laperrousaz]

I want to identify which options where used to compile or link a module (static or dynamic).
Are there some information available in the library headers?

Hi Laurent,

All I can think of at present is to use ldd...


All the best

ldd does not provide such information.

I wrote a small script based on 'strings'

here it is:
strings $1|grep -E 'options|\.cxx'

I added .cxx to get the name of the c++ sources which are named myName.cxx in our applications.

This provides all compilation options for all sources complied in the lib. But it gives too much information

Maybe I can get clearer infirmation adding sed or awk commands?
