Hi,

We're building an application that sits on top of a number of c++ libraries
with different build systems that have evolved over many years. It's a
little messy sometimes :)

We're currently running down a linker error on OS X introduced after one of
our developers got forced into an earlier-than-planned Yosemite upgrade to
accommodate new hardware. This linker error smells like one of the
dependent libraries is being built with -std and -stdlib flags that do not
match the others.

I'm wondering whether there's anything I can use to inspect, say,
libboost_timer.a and determine what flags were used to build it. I'm
specifically interested in std and stdlib. I'd like to write a script to go
through all the .a files in my build tree and see whether any don't match.

Does anyone know whether I could coax this information out of otool or one
of its friends?


Thanks,

Geoff
