(of course when using the portland compiler ;-)

anyway, already some follow-up:

what needs to be done is using
--one_instantiation_per_object
for all .cc files in the libraries, then before building the final 
library, do a
pgCC --one_instantiation_per_object --prelink-objects $CXXFLAGS $LDFLAGS *.o
on all objects.
this will create additional object files in a directory Template.dir

then, when building the library, all the additional object files need to 
be added as well
ar cru normal objects, convenience libraries Template.dir/*.o

[
if i ar cru ' d the convenient library objects from Template.dir/ into 
the convenience library, and then only added the rest to the real 
library, i still get unresolved references...
]

if i do this manually, the prog compiles.

if anybody could put this into something that libtool can do 
(automatically) (maybe with writing some automake hooks or whatever?), i 
would be glad...

thank you,
markus
