Hi,

I'm trying to learn how to add externals objects in PD, I've copied the helloworld file from the classic tutorial. and i'm using some compiling flags from this forum, but this following messages errors are showing up.

g++ -c helloworld.c -o helloworld.o
helloworld.c: In function ‘void helloworld_setup()’:
helloworld.c:25: error: invalid conversion from ‘int’ to ‘t_atomtype’
helloworld.c:25: error:   initializing argument 6 of ‘_class* class_new(t_symbol*, void* (*)(), void (*)(), size_t, int, t_atomtype, ...)’
make: *** [helloworld.o] Error 1

could anyone help me?

THX a lot

Hi everybody,

i'm having problems with the shared libraries.

I have in my work directory: helloworld.c m_pd.h Makefile

my helloworld.c is exactly equal to the tutorial. My Makefile

LIB = m_pd.h

CXX = g++
CFLAGS = -fPIC



helloworld.pd_linux: helloworld.o
    ld $(CFLAGS) -export-dynamic -shared -o helloworld.pd_linux helloworld.o -lc -lm

helloworld.o: helloworld.c
    $(CXX) -c helloworld.c -o helloworld.o


clean: clean
    rm helloworld.pd_linux

.PHONY: distclean

The errors:

ld -fPIC -export-dynamic -shared -o helloworld.pd_linux helloworld.o -lc -lm
ld: helloworld.o: relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC
helloworld.o: could not read symbols: Bad value
make: ** [helloworld.pd_linux] Erro 1

Someone knows this problem with shared libraries?

Thx

In case anyone still looking for this, here is a tutorial for Windows, which might have some translatable advice:
