RE: adding libraries and header file directories

[Jim Rainville]

Hi Ralf - 

I tried adding the --preserver-dup-deps flag in several different ways.
But for some reason it doesn't end up on the link line. I tried adding
it to the front of the LD flags but I'm guessing this is a flag to
libtool instead of to the linker. How do you add flags to libtool? Is
there a special macro to do this?
Below is my link line as you requested.

Thanks for you help.
Jim

Then does adding --preserve-dup-deps (before --mode) help?
If not, then please post again the command that libtool creates from
yours, as you did in this mail (thanks!).

Yes, Libtool is notorious in doing that.  (There's a TODO item to fix
this.)
