Its a linker problem, but not too simple. Your analysis is correct: pistring needs the symbol Parrot_PiSequence_get_integer, so you have to provide it: I did something like this: $ make -C dynclasses $ cp dynclasses/pisequence.so blib/lib/libpisequence.so $ cd dynclasses; cc -shared -L/usr/local/lib -o pistring.so \ -I../include -I../classes -L../blib/lib -lparrot pistring.c \ -lpisequence ; cd .. $ cp dynclasses/pistring.so runtime/parrot/dynext/ $ parrot wl.imc # run your test program 51 52 I also had -Wl,-E in the Makefile, when compiling pisquence. I don't know if its necessary. Another (untested) possibility: you could try to append the 2 pi*.c files into another one and then compile the combined source to a shared lib. > Michal J Wallace leo
