Hi Fred, Thank you! Yes, 512 links perfectly...
It's strange - I sort of saw the circular reference, and tried many times to 'fix' the library 'order', but nothing seemed to work! Each time with different problems... I did _NOT_ think of putting a library TWICE, or perhaps more times, in the list! But I suppose it sort of make sense if the linker does not look back to what it has already resolved! This feels like a 'bug' in the linker, and seems like someone should look at and fix the linker source ;=)) I note from the gcc site - http://gcc.gnu.org - that they have a later release 4.3.3 2009-01-24, compared to my 4.2.4 2008-05-19, and maybe this has been fixed in there. I see I could install this 4.3.3 through the Synaptic Package Manager, and might try this if I get the time... Anyway, lesson learned, and thanks for the speedy fix. And also for the 'const' addition to remove the pesky warning. Regards, Geoff. On Sat, 2009-03-07 at 21:34 +0100, Frederic Bouvier wrote: > I didn't read your message carefully.
