gcc option -Wl,-rpath : what does it mean?

stupendus · 08-13-2007, 10:58 AM

Hi,
I'm trying to debug a package that contains several directories and programs.

I found very often something like this:

-L$(LIBDIR) -lDAQ -Wl,-rpath,$(DAQHOME)/lib

I've searched for -Wl,-rpath in gcc manual but I didn't find anything...

Is there anybody having an idea of what -Wl,-rpath means?

Many thanks in advance!

Regards,
Marco

Right from the man page of gcc

Quote:

-Wl,option Pass option as an option to the linker. If option contains commas, it is split into multiple options at the commas.

This tell the compiler to treat option(s) after "-Wl," as option(s) to the linker. If you look at man ld, you will find the meaning of option -rpath. Cheers!

The part I was looking for was '-rpath' indeed... I was thinking it was a gcc option too... but now I see that linker means ld... Many many thanks!!!
