SAS C tutorial?

[Narf the Mouse]

I'm a complete beginner to SAS C; how do I get from there, to "Hello World!"? Thanks.

[Leffmann]

Quick tutorial:

Download and install the most up to date SAS/C:
https://www.dropbox.com/s/rt23fhty36...sc658.lha?dl=1

Open your SAS/C drawer and the C drawer and run scsetup. Enter f.ex ram:hw to create a new empty project.

Open up your ram:hw drawer and click on edit and type in Hello World:

#include <stdio.h>

int main()
{
  puts("Hello, world!");
  return 0;
}

Rename the file to f.ex hello.c and save it, then click the build icon and your finished program will appear in the project drawer.

If you want to work from the command line instead then you can compile your program with:

sc hello.c LINK

Thanks, it works.

"If you give a mouse a SAS C tutorial..."

What does "Declaration in statement block" mean, and how do I declare a character array (or does it have strings?) Thanks. Edit: Actually, is there a manual/help guide somewhere?

[Leffmann]

SAS/C manuals in text format here:
https://www.dropbox.com/s/5358oxk2dt...tches.zip?dl=1

You also have some quick references in AmigaGuide format in SASC/Help. They don't teach C programming or how to program AmigaOS, just how to use SAS/C.

Sorry to dig up the thread, but this link is now dead.

It is here:

SASC and some more

[emufan]

trying to build something with sasc, all the time gives me some link or resolve errors,
this makes me mad - why do things start allways this way

first it want me to create o/sas-c-classic and bin/sas-c-classic, next this, for example:

what is wrong with this sc 658 setup?

[alkis]

The source code (slib4.c) seems to have the problems and missing a main().

it has a _Startup(void) which is def somewhere else, i have no clue.

initially i was about to compile a lightwave plugin, demscape, this gave similiar errors,
so i was about to try the examples in the sdk and i got same errors.
the example with the errors listed above, is in demscape.lha -> sdk/source/
the demscape plugin src is in the main folder. maybe you can build it

[alkis]

Go to SDK/source dir, open smakefile in an editor

#
# Server library and startup module -- SAS/C makefile
#
UINC    = /include/
ULIB    = /lib/

CFLAGS  = smalldata cpu=68020
SFLAGS  = $(CFLAGS) define RELEASE opt nostkchk IDIR $(UINC)

add the bold part.

type smake
It builds cleanly after adding the include directory.

[emufan]

thanks for your help, but it does fail the same way.

i simply dont understand , why this stupid compiler isnt able to create
those damn temp folder (o/ ... bin/ ... ) on it's own.
maybe my install is all crap or the author should have been using this compiler on it's own , at least once. i dont get it.

[alkis]

you are calling smake, right? From inside the "SDK/source" folder, right?

yes, using the shell, cd , next smake.

and now it works, after i extracted my old archive over the SC: installation. - i dont get it.
but this makes the linking work, without "Enter a DEFINE value" messages.

i have no idea what i have destroyed in the old install, since it did work last time, I build the toasterless software.

now i'm about the compile the demscape plugin, lets see how this works

thnx.

#1) it does build the plugin, but i get some undefined variables at the end,
have to look into it :/

the stupid bin/sas-c-classic o/sas-c-classic folder thing i could fix:
there is a ENVARC:sc/SCOPTIONS files, here are those path configs listed.

#2) sc produce all kind of stupid errors, just because you have set a wrong include path.
the compiler gave me a "non matching or overloaded function" error - sort of experience,
until i "fixed" the default include path to sc:include in the smakefile ...

#3) maybe you can help here again: scan.cc

    int x;
    int startx = (int)ceil(MIN(x1,x2));
    int endx   = (int)floor(MAX(x1,x2));
    if (startx > endx) return;

while linking scan.o

Undefined symbols        First Referenced
@floor__Fd               File 'scan.o'
Enter a DEFINE value for @floor__Fd (default ___stub):

how can I fix this?

#4) hmm, floor and ceil is listed in some math libs (ffp sing doub), i guess a link lib is missing.

#5) i have no clue which scm* lib i have to add, or which math*.h i have to include.
the demscape.lnk file says:

FROM sc:lib/serv_s.o "quadedge.o"+"hfield.o"+"stuff.o"+"Basic.o"+"simplfield.o"+"heap.o"+"scan.o"+"demscape.o"
TO "demscape.p"
LIB sc:lib/server.lib LIB:scm881.lib
    LIB:sc.lib LIB:amiga.lib

and smakefile lists this cpu/fpu option:

CFLAGS  = cpu=68020 math=68881 opt nostkchk idir=$(UINC) idir=cxxinclude:

scan.cc has no #include for any math lib, so how can i fix this error:

Undefined symbols        First Referenced
@floor__Fd               File 'scan.o'
Enter a DEFINE value for @floor__Fd (default ___stub):

adding all remaining errors:

Undefined symbols        First Referenced
@floor__Fd               File 'scan.o'
Enter a DEFINE value for @floor__Fd (default ___stub):

@fabs__Fd                File 'quadedge.o'
Enter a DEFINE value for @fabs__Fd (default ___stub):

#6) somehow ugly and i cannot believe this is the real solution:
in SCOPTIONS file you can add BATCH - from manual:

batch
sets the value of all undefined data symbols to 0 and all
undefined code symbols to _ _ _ stub.
Normally, slink asks you to enter a value for each undefined
symbol. However, if you specify batch, slink does not prompt
you to enter values for undefined symbols.
If an undefined function is called, the library function _ _ stub
(_ _ _stub to the linker) is called instead.
The library's version of _ _ stub displays a requester telling you
that an undefined routine was called and allows you to choose
whether to abort or continue.

[emufan]

after using the BATCH option in SCOPTIONS, i get the stub requester
when using the plugin. so this workaround does work.
but it leaves the plugin non working. so is there an option or an additional lib I have
to link in, to make it build without the "Undefined symbols" compiler request?

[alkis]

Check demscape.zip in the zone.
fixed smakefile, a few minor changes in scan.cc and sdk/include/splug.h in order to compile
.
I've deleted the *.o, kept the demscape.p which I guess is the plugin.

Ignore .uaem files (or delete them)

[emufan]

just tested, it does now open the gui within modeler. thanks alot.
i'll have a look at the changes, wonder what you have fixed.

#1) found the fixes. I can build the plugin now aswell. thnx again

#2) it does really work, very cool

[alkis]

cool

indeed. i think the original version was compiled with an older sdk,
so it didnt work with LW5. this is now fixed

read this:

I have successfully (?????) compiled the code on the Amiga, however I get a startup error when trying to run the plugin. I cannot figure out what the problem is,

it simply didnt work, so you made it work for the first time ever

#1) the intel version comes with a dem shader plugin, but no src included.

[alkis]

In the zone, a new zip with hopefully a working demshade pluggin.
