Comment(by j...@…):
If I use gcc-4.4 this works fine, it occurs only with 4.5 as it is in
Ubuntu 11.04 devel. The flag that apparently causes it is --no-add-needed
. Running the gcc command without that flag leads to successful linkage.
I am not sure why this is ARM only and whether it is a gcc or ghc6 issue
mostly?
Should pthread be explicitly mentioned in the link list? I see that it
gets linked to the final executable when the build works.
