Crazy Library Failure

[Zetr0]

Hello thre my fello z88dk'ers

I recently managed to get file-handling working very well, then strangely when playing around with the graphics routines I then ended up with an uncompileable error.

Now, I have been plauged by this problem for the last couple of hours and its driving me crazy as I have no idea why its having such fit when it was working fine. so I slapped up a simple hello-word and its still having the same problems -

Test Code

Code: Select all

#include <stdio.h>

void main( void )
{
  printf("hello world");
}

Very simple stuff -


Compile Line

Code: Select all

zcc +zxansi -lp3 -DPLUS3 -lm -create-app program.c >build.txt

All of a sudden for no reason I am recieving this error output

Result

Code: Select all

zcc +zxansi -lp3 -DPLUS3 -lm -create-app program.c 1>build.txt
2 errors occurred during assembly
Key to filenames:
C:\DOCUME~1\Zetr0\Locals~1\Temp\s4fo_.o = program.c
File 'C:\PROGR~1\z88dk\lib\clibs/p3.lib', Module 'FREEHAND', Symbol not defined

Error in expression _HAND_STATUS

File 'C:\PROGR~1\z88dk\lib\clibs/p3.lib', Module 'FREEHAND', Symbol not defined

Error in expression _HAND_STATUS

obviously if I change the "-lp3" to say "-lndos", everything compiles, although theres no +3 disk IO (which my project sorely needs)

I honestly don't know what to do at present.... I have tried uninstalling z88dk and installing it once again and the error is still present - its just very pecular and I could use your help


here is the build log

I believe I know what the problem is. The simple helloworld is not compiling because "hand_status" is never declared. This comes from findhand.c which never gets linked in.

The crt0 contains code to close all open files which I think eventually calls close.c which calls freehand.c which references the variable hand_status. With no use of fopen() or some other function requiring finding a handle, hand_status is not declared.

To fix it, all the global variables probably should be moved to the crt0.

My sincere thanks for reading this post,

Some most awesome chummies over at WorldofSpectrum also pointed this fault out, its quite ironic that I discovered this issue because I was being lazing in a bit of code - after testing a couple of file-handling routines, I "/* */" them out to focus on some graphic display code ("within the same program file") however because fopen or flcose was not used - it developed this error.

It wasn't untill much later when I realized I could complile the program with the "-lndos" dummy retainer instead of the "-lp3" library that I suspected somthing like the above had taken place...

I have to admit I really am loving z88dk, sure it has peculiarities, and its some what, seat-of-your-pants coding, but I am truly loving it!
