Screen Blanker & MiniGL ?

Hi,

I tried to compiles some blanker source code available on www.os4depot.net
For my sample I used the "commander.blanker" one.

By removing all referencies to Picasso96 and CybergraphX, the blanker compiles ... Only problem settings and display are not handled correctly ... but it's not the problem here...

When I try to include MiniGL and compiles the blanker,
I get these errors :
Quote:
gcc -D__NOLIBBASE__ -D__NOGLOBALIFACE__ -D__AMIGADATE__=\"`c:date LFORMAT %d.%m.%Y`\" -DMINIGL -Wall -Werror -O3 -c -o Blanker_AmiDARK.o Blanker_AmiDARK.c
gcc -mcrt=newlib -nostartfiles -lm -o AmiDARK.blanker Blanker_AmiDARK.o -lAmiDARK -lm -lGL -lGLUT
/SDK/newlib/lib/libGLUT.a(glutstub.o): In function `glutInit':
include/mgl/glut.h:23: multiple definition of `IIntuition'
Blanker_AmiDARK.o:(.sbss+0x6c): first defined here
/SDK/newlib/lib/libGLUT.a(glutstub.o): In function `glutInit':
include/mgl/glut.h:24: multiple definition of `IntuitionBase'
Blanker_FlyingFeather.o:(.sbss+0x24): first defined here
make: *** [AmiDARK.blanker] Error 1


if I remove intuition definition from the blanker file, I get errors saying that Intuition is not defined ( where some IIntuition->.... calls are made )

Does someone know how to find a solution to "ignore multiple definition" ? or to fix this ?

You can try to remove intuition definition from the blanker file, and add -lauto at linking stage.

Try to add -D__USE_INLINE__=1 at compiling stage.

And try to compile Amidark itself with -gstabs options (all the object i mean which you put into libamidark.a), then compile blanker as well with -gstabs, and try to do reboot/prefs/blanker few times, and for one of them it should give you GR, so, you can press stack-trace, and by addr2line detect on which line of code it crashes:

If it crashes on something intuition related - then the problem is it, but if not - then it will show where a problem.

But from my experience i can say that if you compile a binary with that -lauto + USE_INLINE, then all that IFACE stuff are not matter.

same.
if I keep IIntutionBase in blanker source code, I get "multiple definition of 'IntuitionBase'
if I remove it I get it as not defined on the function OpenLibraries of the blanker source code.

A few things for you to try:
- Put extern in front of your IIntuition definition in Blanker_AmiDARK.c
- Try changing the order of the linker libs, e.g., move -lGLUT closer to the front

I'm not sure if GLUT will work within a blanker, as it was designed for standalone apps. Nevertheless, if you can get it working, great.

Will try this today ...

Maybe that if someone have access to the source code minigl blanker(s) we have on OS4 ... it may help ... :p

Did you add an = NULL after your declaration of IntuitionBase and IIntuition? If so, remove them. That's the task of whichever source file has the actual global declaration (the GLUT lib, in this case).

It's -lGLUT, not -IGLUT (i.e., use a lowercase L, not an upper case I).

Thank you Hans,

Now it compile correctly.

I haven't changes the blanker inside the lib, it's always the commander one.
When I try to test module ... it send grim reaper ...
I'll try to find how to fix this ...
The preview of the blanker work ok.

EDIT :
I've fixed the crash but readding the openlibrary/getinterface for Intuition.
(I think MiniGL is not automatically setup when the lib is run)

Speaking of blankers and MiniGL. All the source code for the glBlankers I ported from xscreensavers are available here:

Just below the tab "Forks/Queues" there is a link called "get sources" this allows you to get everything zipped.

EDIT :
And, more to this, when I want to save 1 file ( right click and save target as ... ) it save the file as .htm file format with the entire page setup ... not only the source code :(

Yep, the same for me. 404 all the time

Btw, how looks like stack trace of your GR ? can you put stack-trace only here ?

I just noticed the 404 and reported it to bitbucket.
Maybe the source archives are only generated once a day or something and has not been generated yet.

For my other repository on bitbucket it works fine.

So maybe wait till tomorrow.

Ok,
I've DL 1 blanker and the template and common/blankerstartup files
so I can start checking how you've done them :)

Maybe if you doest mind we also can upload it on os4depot ? That will help a lot later for everyone who will want to write a blanker (more examples the better).

@freddix
Why i ask, its just in hope that it was crash on mglut (as for me with latest version of amidark), and maybe you fix something like that :)
