Nonono. Time to upgrade (?) the gcc source. I haven't looked into the source
yet, but there must be a reason why the compiler asks for 2.0 libraries.
The person who compiled gcc for the Amiga simply had a 2.0 machine, and if
someone would be willing and able to compile it on a 1.3 machine, the other
half(?) of the Amiga-community would thank him/her.

How did the person from who the Amiga-gcc came compile the source? If it was
on a Unix-machine, even I might be able to do it. If it was on an Amiga,
things look bad for me *smirk*... If anyone can inform me on how to make or
better, obtain an 1.3 gcc, I'd be very happy. :-)

Subject: GadTools CYCLE_KIND gadgets
Date: 6 Apr 92 07:26:15 GMT
Organization: Mathematics and Computer Science, Aalborg University

Hi! 

Sorry if this has been answered in this newsgroup before but I just recently
got my 2.04 roms...

I am using some GadTools CYCLE_KIND gadgets in an application I am
currently working on, and I have a couple of questions on how to use
these as I haven't got the 2.04 RKM's yet.

1) I am using the cycle gadgets for e.g. selecting how the data is
   presented to the user: a simple listing, misc. statistics, graphs etc.
   This can also be selected through menus and keyboard shortcuts. 
   When I e.g. select a certain type of presentation by using the pull-down 
   menu I have to update the corresponding cycle gadget in order to
   display the correct text. So, how can I control which text is being
   displayed int the cycle gadget?

2) One of my cycle gadgets cycles between 3 texts. How do I determine 
   which text is active, when the gadget is clicked (i.e. after I 
   receive the GADGET_UP IDCMP)?

Any help would be very much appreciated!

Regards,
  Lars Bodin

Agreed! It does sometimes screw up the text in the ListViews, but it does
include the source.  The only problem is that I can't recompile it 'cause it
didn't include the nofrag.library include file!!!

Subject: free -- how it works
Date: 13 Apr 92 06:25:28 GMT
Organization: The Synthy EuroTechnoWack Beat, Inc.

Somebody has to keep this group moving :-) so here is a semi-non-Amiga
question about the standard C library function, free().  In the following
code, which I compiled with DICE, I declare p as a pointer to pointer to int.
The program first gets space for p, then for *p.  Then it frees *p, and
finally it frees p.  This happens 1000 times in the for loop.

Now, the question.  If the free(*p) statement is commented out, the
program still seems to free all memory that it mallocs.  That is, after
running the program several times, 'avail' still shows the same amount
of memory before running as after.  Why?  If we don't free(*p), there should
be 1000 ints * 4 bytes/int == 4000 bytes eaten each time the program runs.
Or do I misunderstand how the free() function works?  (That's probably it :-)

In my K & R, it says "free deallocates the space pointed to by p".  Since
in this case p points to another pointer, I thought free(p) would only
deallocate the pointer, *p, that p points to.  But free(p) seems to be
freeing *p and **p.
-----------------------------------------------------
#include <stdio.h>
#include <stdlib.h>

main(void)
{
    int i, **p;

    printf("\n      ");
    for (i=0; i < 1000; i++) {
        p = (int **) malloc(sizeof(int *));
        *p = (int *) malloc(sizeof(int));
        free(*p);                             /* comment out this line */
        free(p);
        printf("\b\b\b\b\b\b%6d", i);
    }
    printf("\b\b\b\b\b\bDone.   \n\n");

    exit(0);
}

	If it's a system function:

You can examine ram:lvos for the offsets.

Yes, it is fairly easy to deal with this annoying window.

You need to modify _main.c (in the 5.10b w/ ansi libs version, called
__main.c before then I believe) and recompile.  This file should be
located in lc:/source.  If the changes are straight foward for you,
I can help via email.

I was trying to program a simple routine to put text into any window simply
by giving the correct raster port.  A simple task which turned out harder
than one would expect.  I must be doing some little thing wrong.  Because
text to a window is so common someone must already have written the routine.
if you could mail it to me i would appericiate it.  If anyone knows where there
are other helpful common routines in public domain I would appreciate your     
telling me where I could find them.
 My routine was to simple put the desired text in to any window with a statementlike this:
  printw("text here",RastP);
I was using PrintIText.  I'm not really sure what went wrong.
Random numbers seems to be another complexing issue.
How do you make your own include files.  If wrote a routine could I simply
make it an include.   #include"myfile";

If you are using SAS (Don't know about Manx, DICE, etc) then the startup code in c.o
already opens dos.library for you.  Opening it again might be causing the GURUs
under 1.3.  You can use another library (i.e. graphics.library) or (I think)
there is a version number inbedded in ExecBase->SoftVer that can be extracted
and used.

Not much... the routine name must be preceeded by a "_". Use the XDEF
directive (e.g. XDEF _routine) to make it visible in the object file.
Normally the parameters will be passed on the stack. So, you can grab
the pointer with move.l 4(sp),a0. That's it!

Thank you to Stefan Becker and John Bickers (similar last names :-) for being
the first two (and only, as of now) people to respond to my question about
using shared libraries with DICE 2.06.40R.  Specifically, I wanted to use
Nico Francois' ReqTools Library v1.0d with WB 1.3.

I think I have it working now.

Eliminating the technical details (I'd have to consult the response from
John Bickers), basically DICE requires reqtoolss.lib at linking while
SAS C (for example) uses pragmas.  The demo.c that comes with ReqTools is
set up to compile with SAS (I think), so there were some extra header files
(containing pragmas and other stuff) that I didn't need with DICE.  Also,
to be safe I put the hooks.h and tags.h files in the amiga13/utility
directory in DINCLUDE:.  Finally, the compile syntax is (thanks Stefan!):

   Shell1> dcc -o demo demo.c -lreqtools

I had it a bit mixed up, but never mind that.  :-)

No specific programming FAQ sheets.  There is a good general Amiga FAQ
sheet that Jeff Hyche posts to comp.sys.amiga.introduction every month.

Also, I post a "Tips for the Beginning Amiga C Programmer" article to
this board monthly.  This may be a bit more basic than what you need,
but if you or anyone (which is why I'm posting instead of mailing)
wants one, you can mail to me.  Or just wait until May 1st.  I also keep

Or, even better, use the window pointer as an indicator if it is open
by clearing it after you close it. As OpenWindow() returns NULL if it
fails, it is a perfect "BOOL". This is nice for your cleanup, too.

First of all, thanks Markus Wild for your great efforts!

I have got GCC2.0 up and working, but have a question -> How can I call
Amiga run time libraries from a program compiled by GCC?

Actually, the above isn't really the question at all, now that I think
about it.  The REAL question is, how can I do this WITHOUT writing the
inline headers/stubs myself by manually looking at what's provided, and
using the info from an fd file? 
 
Thanks,

Amish S. Dave (asd2@midway.uchicago.edu)

p.s. A note to any besides me who are looking to get GCC2.0 working w/o
having looked at GCC1.40:  hunk2gcc is in the earlier GCC (1.40 or 1.39,
I forget) release, and will let you convert most link libraries and object
files from at least SAS (don't know about other compilers).
