Latest CC65 does not compile old Lynx code anymore

[lucienEn]

Hi, after more than a decade I thought I'll compile my old Lynx game but noticed the super old cc65.exe copy I have does not run anymore on 64-bit windows.

So I downloaded latest cc65.exe but that gives compile errors for the standard header files. Any idea how to fix this? E.g.:

 

\arcmenu>cc65 -ILynxDev\CR\INCLUDE arcmenu.c
LynxDev\CR\INCLUDE/stdlib.h:12: Warning: Implicit 'int' return type is an obsolete feature
LynxDev\CR\INCLUDE/stdlib.h:13: Warning: Implicit 'int' return type is an obsolete feature

LynxDev\CR\INCLUDE/stdlib.h:19: Warning: Implicit 'int' return type is an obsolete feature

...

LynxDev\CR\INCLUDE/../runtime/global.m65:4: Warning: Implicit 'int' is an obsolete feature
LynxDev\CR\INCLUDE/../runtime/global.m65:4: Error: ';' expected
...

 

arcmenu.c:

#include "lynx2.h"
#include <lynxlib.h>
#include "loader.h"
...

 

Thanks!

What is in line 12 in stdlib.h ? Maybe adding "int" as return value is sufficient?

Well, actually the compiler is the newcc65. And it appers to cast int's to pointers both ways. So it just does not run on 64 bit systems.

 

As the code is mainly #asm blocks it is a bit hard to port to the modern cc65 variant.

 

The problem comes from extra attributes not known to cc65 Like unsigned char something at $FF00;

 

If someone has a newcc65 that runs on 64 bit machines I am sure Lucien would appreciate it.

My "old" newcc65 is running fine on a Win 10 64 bits, and even Win 11 on my convention laptop IIRC.

I will try to make an archive, but i don't know when (if not before monday, it will probably delayed by 1 week)
