If you're using 64-bit processor - which nowadays is quite common - you can
|
||
|
|
compile 4th as 64-bit compiler. To do this, just delete patch #02 before
|
||
|
|
compilation. But read the following excerpt from original 4th docs first:
|
||
|
|
|
||
|
|
|
||
|
|
25.7 <sec:64-bit-platforms>64-bit platforms
|
||
|
|
|
||
|
|
Although 4tH will work perfectly well on a 64-bit platform there
|
||
|
|
are some disadvantages:
|
||
|
|
|
||
|
|
• HX files generated by this compiler are not portable to 32-bit
|
||
|
|
platforms
|
||
|
|
|
||
|
|
• Some 4tH library files may not work properly without some
|
||
|
|
modifications.
|
||
|
|
|
||
|
|
A quick fix is to change the size of a cell to a four byte
|
||
|
|
datatype. The following procedure will usually work. Open 4th.h
|
||
|
|
and change these lines:
|
||
|
|
|
||
|
|
#define CELL_MIN LONG_MIN
|
||
|
|
|
||
|
|
#define CELL_MAX LONG_MAX
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
typedef long cell;
|
||
|
|
|
||
|
|
To this:
|
||
|
|
|
||
|
|
#define CELL_MIN INT_MIN
|
||
|
|
|
||
|
|
#define CELL_MAX INT_MAX
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
typedef int cell;
|
||
|
|
|
||
|
|
Save 4th.h and compile as described in the previous sections. If
|
||
|
|
you want a full 64-bit 4tH compiler, be aware that:
|
||
|
|
|
||
|
|
• You cannot compile 4tH as a shared library
|
||
|
|
|
||
|
|
• You have to regenerate the include files manually, unless
|
||
|
|
you're working with Linux.
|
||
|
|
|
||
|
|
Linux automatically recreates the include files each time you
|
||
|
|
perform a compile. If you're working with a GNU toolset, you may
|
||
|
|
try the Linux Makefile. If that doesn't work or isn't an option
|
||
|
|
in your particular situation you'll have to perform the procedure
|
||
|
|
listed in section [sec:Regenerating-the-include].
