is there any way to change the order of name resolution in linking (aside from putting the libraries in the right order?)

[Vardhan, Sundara (GE Transportation)]

Hi Dan

I think -l defaults to .so and does not include .a if the extension is
not explicitly mentioned. However, I am not sure if anything in this
area changed in the latest gcc.

Regards

Vardhan

It didn't resolve the reference.

To be really specific here (except that i have to suppress some of the
dozens of characters in the command), the command generated was:

gcc-4.6  -Wl,--whole-archive,-lX11,--no-whole-archive  [[[other stuff
deleted]]]

And that command gives the same result as just putting -lX11 first (as
opposed to putting it last, which resolves everything).

(It may be that the -l option somehow signifies *.so these days?
Because it certainly gives a much smaller executable when it works, and
i had to use the *.a forms with --whole-archive in order to make it
work?)
