Why doesn't this Hello World X11 code run on NetBSD?

Question

I am on a brand new 5.1 NetBSD box.

I copied the "Hello World" code from here rosettacode.org

The code compiles with this command:

cc -I /usr/X11R7/include -L /usr/X11R7/lib -lX11 helloworld.c

When I run a.out, I get the following error:

Shared object "libX11.so.6" not found

I confirmed that /usr/X11R7/lib/libX11.so.6 does exist.

ldd output:

./a.out:
    -lX11.6 => not found
    -c.12 => /usr/lib/libc.so.12

How do I properly link against X11 on NetBSD?

Answer 1

The official NetBSD answer is to use RPATH. Crazy.
