Thanks for this advice, but I use -lm already ! And it doesn't work.
I am not sure that the math-lib is the reason for
example.o: unresolved symbol fputs
example.o: unresolved symbol stderr
example.o: unresolved symbol __errno_location
but it seems so, if I look with the nm-command.

It IS possible to use the math library in modules; I've been doing
it for
several years. But -- except for certain selected functions -- you
can not
use the standard library functions.
To link your module with the math library, just add "-lm" to the
partial
link command. Even if you don't want to run with it, it's worth
doing to
see if that's where your problems lie.
