Comment 2 Tom Henderson 2008-09-04 11:24:22 UTC

this was fixed yesterday in changeset 693faf7f439b

Comment 3 Tom Henderson 2008-09-07 12:28:34 UTC

This bug seems to have crept back in:

machine:  ns-regression (gcc-4.2.3 Ubuntu x86)

[496/536] cxx_link: build/debug/samples/main-callback_2.o -> build/debug/samples/main-callback
debug/libns3.so: undefined reference to `dlopen'
debug/libns3.so: undefined reference to `dlclose'
debug/libns3.so: undefined reference to `dlerror'
debug/libns3.so: undefined reference to `dlsym'
collect2: ld returned 1 exit status

Comment 4 Tom Henderson 2008-09-08 09:37:15 UTC

(changing title to reflect new information)

This can be repeated by forcibly disabling gtk-config-store from the build (I didn't see a waf option) and gtk.h won't get pulled in.  It can be solved by installing or enabling gtk-config-store.

Comment 5 Mathieu Lacage 2008-09-08 12:38:05 UTC

I can't reproduce this with any gcc I tried it on.

Comment 6 Tom Henderson 2008-09-09 03:37:41 UTC

I couldn't reproduce again tonight, so it must have been fixed sometime today.
