Can SDCC (Small Device C Compiler) be used with BCX?
« on: August 03, 2022, 12:11:25 PM »
Does anyone know if it would be possible to use SDCC with BCX to compile text only (console) programs for 8-bit machines?

Hello Wysardry and welcome to the BCX forum.

Short answer - no.

Longer answer - BCX is a code-to-code translator, not a compiler.
That means you -could- use some of the features of the BCX BASIC language to write some "c" code for you.

A simple, fictionalized version of this idea:

Demonstration.bas
Code: [Select]
$ZAP
$NOWIN
$WARNINGS_ON

#include SomeSDCCHeader.h

SUB MAIN
    DIM Foo1 AS SomeSDCCDataType
    DIM Foo2[256] AS CHAR
    DIM Foo3 AS INTEGER

    FOR INT i = 1 TO 10
        CALL SomeSDCCFunction(Foo1, Foo2, Foo3)
    NEXT

END SUB



would be translated thusly:

some of which you might find useful.

I probably phrased that badly. I meant is it possible to use BCX with SDCC (instead of Pelles C or one of the other C compilers that are known to work) to create text only programs that will run on 8-bit computers?

I have used BCX in the past, but it was around ten years ago and only to create Windows programs. I'm fairly sure I used something called "BCX DevSuite" or similar that also installed an IDE and compiler and set them up.

I am not sure if BCX adds Windows specific code to console programs or if it can create C code that follows any of the standards that SDCC can handle (ANSI C89, ISO C99, ISO C11).

I dislike C-style syntax and am hoping to avoid working directly in C source code as much as possible.

BCX makes heavy use of the WinApi, even for console mode programs.  You won't get away with much beyond
PRINT "Hello, World!" without some call to the WinApi.  Basic keywords like: LOCATE, COLOR, CLS, etc all have
WinAPI dependencies.

If you're looking for a somewhat agnostic version of BCX, you could look at

https://github.com/Airr/MBC

but I won't be able to answer many questions about this.  There are others, including the recently returned
forum member and author of MBC ( Armando Rivera ) who might be able to provide some guidance.

I would like to be able to create several text adventures (similar to Colossal Cave Adventure), so I shouldn't need to use many commands that rely on the WinAPI.

I'm hoping that SDCC includes routines for clearing the screen etc. that I could access via inline C code if need be.

MBC looks interesting, especially as I also own a Raspberry Pi that I haven't done much with yet. Does it also run on Windows?
