do you know where I can find the pd lib?
thanks for all Martin

The errors are probably because you are not linking against pd.lib,
which is where the undefined symbols are hiding.

Objet: [PD] error compiling any2string
I get this error compiling any2string.c
does anyone have these moocow externals compiled for mac intel?
thks list
cc any2string.c -o any2string
/usr/bin/ld: Undefined symbols:
_main
But looking for main implies that you are compiling a program. A pd
external is a dynamic library.
It seems to me you are on some kind of mac, which I don't know about,
but I'll try anyway.
Stealing a line or two from a typical pd makefile:
CFLAGS = -DPD $(OPT_CFLAGS) -I$(pd_src)/src -W $(DEBUG_CFLAGS)
LDFLAGS =
LIBS = -lm
ifeq ($(OS_NAME),darwin)
CFLAGS += -I/sw/include -DMACOSX -DUNIX -Dunix
LDFLAGS += -bundle -bundle_loader $(pd_src)/bin/pd -L/sw/lib
LIBS += -lc
DYLIB_LDFLAGS = -dynamiclib -read_only_relocs warning -L/sw/lib
DYLIB_EXTENSION = dylib
STRIP = strip -x
and
### C files
%.o: %.c
$(CC) $(CFLAGS) -o "$*.o" -c "$*.c"
%.$(EXTENSION): %.o
$(CC) $(LDFLAGS) -o "$*.$(EXTENSION)" "$*.o" $(LIBS) \
`test -f $*.libs && cat $*.libs` \
`test -f $(dir $*)../$(BUILDSRC_OS_NAME)/$(notdir $*).libs && \
cat $(dir $*)../$(BUILDSRC_OS_NAME)/$(notdir $*).libs`
chmod a-x "$*.$(EXTENSION)"
$(STRIP) $*.$(EXTENSION)
rm -f -- $*.o
This implies that instead of:
cc any2string.c -o any2string
you should write:
cc any2string.c -DPD -I/sw/include -I$(pd_src)/src -DMACOSX -DUNIX
-Dunix -o any2string.o
to compile it, and if that works,
cc -bundle -bundle_loader $(pd_src)/bin/pd -L/sw/lib -o
anystring.pd_darwin any2string.o -lm -lc
which will link it...except that $(pd_src) should be the path to your pd
source.
Then:
chmod a-x any2string.pd_darwin
since it's not an executable file, and:
strip -x any2string.pd_darwin
to remove unused code from the binary.
But I don't really know, not having tried it ;(.
