[Neko] Re: Compiling on OSX

Mon, 18 May 2009 15:15:17 -0700

I finally got it working, and in case anyone is interested i'm attaching a patch of the changes. I don't know if they break anything on other platforms, but i've tried to keep it in the osx defines.

Attachment: osx.patch
Description: Binary data

After some help from people at stackoverflow (http://stackoverflow.com/questions/872726/errors-while-compiling-neko-vm-os-x 
) I've now gotten one step further to the compiling of neko on osx.


What i had to do was to add this before #include "vm.h":

#include <dlfcn.h>


That's because the dlfcn.h redefines the bool into "_Bool" (in /usr/ 
lib/gcc/i686-apple-darwin9/4.0.1/include/stdbool.h) while the neko.h  
header has it defined as "int".



Now on the other hand i'm stuck when it tries to compile mod_tora2,  
i get this output:


Compiling mod_tora2...

Since i'm currently not planning on using mod_tora can i skip this  
in the compile somehow?


Cheers!

Hey, I'm trying to compile on my macbook (osx 10.5.6) and getting  
some compile errors.



I can't say I'm used to compile alot of c source code so i need  
some help with this.



First, since i've installed the libgc using macports i had to add "  
-L/opt/local/lib -I/opt/local/include" to the CFLAGS to avoid those  
errors.



Second, it complained about not finding malloc.h, and after som  
googling it seems it's not available in osx (?) so it might be  
ignored, so i changed the malloc include in jit_x86.c to:


#ifndef NEKO_MAC
#       include <malloc.h>
#endif


And now i'm completely stuck, because it stops at the compiling of  
the threads.c saying:


vm/threads.c:202: error: conflicting types for 'neko_thread_register'

vm/neko_vm.h:37: error: previous declaration of  
'neko_thread_register' was here



I've tried googling this and some say it's because of lack of a  
"prototype" and some say it's because of a header include being  
done several times, and i can't really find any of those.



It might be related to the bool typedef though, because when i  
compile with -x c++ i get other errors (although off course those  
might be earlier than the "conflicting types" issue. The error i  
get as cpp is:


vm/threads.c: In function 'void* ThreadMain(void*)':

vm/threads.c:112: error: invalid conversion from 'int (*)(int,  
void*)' to 'void*'
vm/threads.c:112: error:   initializing argument 2 of 'int  
clean_c_stack(int, void*)'

vm/threads.c: In function 'mt_local* neko_alloc_local()':

vm/threads.c:252: error: invalid conversion from 'void*' to  
'mt_local*'



I'd appreciate some ideas on what i might be able to do here, i  
don't really know where to go from here.


Thanks!

ps. i'm trying to make a macport of neko and haxe which is why i'm  
doing this in the first place :)
