this morning i've test to make a C++ external with maxcpp ( in order to use Gecode later...)

i've copy the maxcpp5.h in my xcode project (C++ command line tool)

but when i try to compile the first exemple Xcode apparently don't find "ext.h"

that's weird because i've add MaxAPI.framework to my project...

if anyone has a hint for me it will be welcome :)

i'm not a high level developer so... be kind to me plz

I can't compile it, i've tried some change but i'm stack on " #include " 'new' file not found...

I can't compile it, i've tried some change but i'm stack on " #include  " 'new' file not found...

ok i've fix the 'new' thing but there is still issues:

MaxCpp5::makeMaxClass(char const*) in dummy++.o

ld: symbol(s) not found for architecture i386

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Undefined symbols for architecture i386:

Does anyone could send me a .xcodeproj of a simple C++ external? It would be really nice :)

I'm going mad with it...

I think it will be the best solution...

thank you vanille, i will look at commonsyms.c

great explainations , i think it will help me

I use maxcpp with max 6 SDK , is it possible or am I suppose to use it with max 5 SDK?

i was finaly able to compile it, i've made a really stupid mistake (that i will keep secret) but now it works :)

is it possible to add methods that don't need selector?

example.mxo "doesn't understand" int or float without selector

thank you a lot for your time vanille, you are the only one who help me, i really appreciate

I have work on C external yesterday and lot of things are more clear now ( i've reread the begining of the SDK :) .... )

I really need to use Gecode that's why i'm going C++ now, i've start C only 2 weeks ago and even if i'm working hard it takes time to become "natural" and it takes even more time with C++ that's looks harder than C!!! so excuse the noobish questions plz...

For int and float register_method, I posted an answer here :

you can make C++ external a different way:

if (x = (t_simplemax *)object_alloc((t_class *) simplemax_class)) {

//add in pointer to t_class for c plus plus - only line changed!

this is in the new declaration at the bottom of the file. So you are forcing simplemax_class to be a t_class pointer. Somehow this allows you to use C++ now instead of C in your code.

I've done a few things in C++ - using classes etc and never had any problems. Thanks Jeremy Bernstein for the tip.

1. change :
if (x = (t_simplemax *)object_alloc((t_class *) simplemax_class)) {
//add in pointer to t_class for c plus plus - only line changed!

I think I'm having the same trouble as FREEPOULITE,

Undefined symbols for architecture x86_64:

MaxCpp6::makeMaxClass(char const*) in maxcpp-test.o

ld: symbol(s) not found for architecture x86_64

I get this compile error:
Undefined symbols for architecture x86_64:
  "_common_symbols_init", referenced from:
      MaxCpp6::makeMaxClass(char const*) in maxcpp-test.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

hope it's okay to reply here, but if you ever get something like:

hopefully the (t_class*) cast idea above works out for anyone doing c++ externals. you could of course use faust to do this

it's because there's a mix and match of
myexternalobject.c
