HiTech C v 309 - how to get cross reference and printer listing for debugging?

[rwd...@gmail.com]

I am learning old-fashioned C and as a first step I have ported my simple hexdump program from PLI to C but am confused by the parameters for compiler operation to get a symbol file for  a debugger and a listing file of source and generated assembler code.

Can anyone assist with showing me an appropriate command line for the hi-tech c v309 compiler?

Cheers

To get a symbol file for the HI-TECH debugger (DEBUG) you'll need to link separately.

For example, you can compile with the verbose -V switch to see what the compiler does -

C>type test.c

#include <stdio.h>

main()

{

    int i, j;

    scanf("%d", &i);    /* read a decimal number from stdio */

    printf("%d\n", j);  /* echo it back */ /*Note the error - j should be i */

}

C>c -v test.c

(on my system I have an ENVIRON file on the A: drive in user 0 that sets TMP to use drive M: - my ramdisk, so the output you see may be slightly different).  For the above program run, I typed '123' and pressed the enter key.  You can

see it has echoed the wrong variable by outputting the 0.

To get a listing you can stop the compilation after the code generation phase, use the -S switch

C>c -s test.c

Now you can assemble using ZAS and specify a listing file

C>zas -Ltest.prn test.as

A:ZAS      COM

I won't include the listing TEST.PRN file output here for brevity.

Now link it together with the library routines and get a symbol file using the -d switch

(here I'm using the interactive prompting mode of the HI-TECH linker with line

continuation) -

C>linq

A:LINQ     COM
link> -d -Z -Ptext=0,data,bss -C100H -Otest.com \
link> 0:a:crtcpm.obj test.obj 0:a:libc.lib

C>

Now run the debugger (the symbol file is L.SYM)

C>debug test.com l.sym

A:DEBUG    COM

:  

I won't go through the debugging details here - instead refer to the debugger documentation

(which has this very same example) in

https://github.com/agn453/HI-TECH-Z80-C/blob/master/doc/DEBUGMAN.TXT

It shows you how to patch the incorrect reference to the variable j.

I hope this gives you a better idea.

Thank you, I shall give that a try.
