The outdated libc.so wasn't the problem, i still get the very same crash on accessing an engine .so

Makefile question.

I'd like to automate the process of building and linking a static library.
Can this be done in one makefile?

Right now i have this, but ar is never picked up.


CXX            =    g++

CXXFLAGS    =    -Wall -Wextra -g -gstabs `sdl-config --cflags --static-libs` -std=gnu++11 -ISDK:local/common/include/libxml2

SDL_LIBS        =    `sdl-config --static-libs` \

                -lSDL_image -ltiff -lpng -ljpeg -lwebp \

                -lSDL



OBJS =            lots.o of.o o.o files.o



libmylib.a: $(OBJS)

        $(CXX) $(LDFLAGS) -o $@ $(OBJS) $(SDL_LIBS) -lm -lz -lpthread

        ar rcsv libmylib.a $(OBJS)



clean:

    rm -f *.o libmylib.a

Thank you

@Raziel

For a static library you only need:


AR = ar



OBJS = lots.o of.o o.o files.o



libmylib.a: $(OBJS)

    $(AR) -crv libmylib.a $(OBJS)



clean:

    rm -f *.o libmylib.a

Note that for the commands following the dependency rules (ar and rm) you absolutely need to have a tab character at the beginning of the line or they won't work.

Maybe this is something that should be added to minigl?

I don't understand, does that mean it's already supported, but not yet released?

I really want (to try) to tackle this, so, if you got time, please help...

Quote:

Looks you might have a NULL IDOS pointer. If you add the following code to your main() function it could give a hint as to what is going wrong:
extern struct DOSIFace *IDOS; extern unsigned const int *__newlib_minversion_ptr; printf("IDOS: %p\n", IDOS); printf("Minimum newlib version: %u.%u\n", *__newlib_minversion_ptr >> 16, *__newlib_minversion_ptr & 0xffff);

This is what i get on serial:
Quote:

IDOS: 0x6FCCC170
Minimum newlib version: 52.20

Quote:

There is a problem with older newlibs if the requested minimum version is >= 52.39** that leads to DOSBase and IDOS not being properly initialised. It does not appear to be the reason for your problem though judging from the above output.

If the crash was in a shared object it could be that it is unable to access the IDOS symbol from the main executable and this is leading to the NULL pointer access, but that does not look to be the case judging from the stack backtrace...

So, if i understand that correctly, some part of my SDK is linking the project with an outdated newlib library version, correct?
Or why could it be requesting 53.20 and not the newer one?

Is there something i can update in my toolchain to prevent that?
Maybe newlib (though i thought i have everything uptodate my libc.so was outdated, so other things might be aswell)?

Also, any more debug output i could add?
What kind of information/output would be needed?

EDIT:
Also, how can i PrintF characters or strings, if the variable to debug should have a path or directory name in it?
I can't get my head around using %s or %c, at least they only output garbage most of the time.

Thank you very much

printf("char: %c\\n", 'a');

printf("string: %s\\n", "C string");



std::string str("C++ string");



printf("C++ string: %s\\n", str.c_str()); // http://www.cplusplus.com/reference/string/string/c_str/

Some info: http://www.cplusplus.com/reference/cstdio/printf/

Ps. regarding that texture format, I was just thinking that it probably wouldn't be difficult to add support for that missing format in MiniGL.

Yes, i read the manual, still i am unnsure on how to print out certain variables.
I'm still thinking in AREXX scripts, i guess.

e.g. if i wanted to print out the variable "p" or "*p" from here:
https://github.com/scummvm/scummvm/blo ... gaos4/amigaos4-fs.cpp#L81
How would i achieve that?
Not that i think there's anything wrong with the path, just for learning purposes (as i think that p holds the path where it tries to load from...but maybe i'm completely wrong again?).

@Raziel

Right, so "p" is an reference (&) to a String object that exists in Common namespace (Common::String). When it comes to C++ objects, typically we can only "print" their address using %p, but as we can see in the same function, Common::String has a similar member function than normal std::string, called c_str() that apparently returns a C string that lives inside the object. So you can use something like

printf("String: %s\n", p.c_str());

I see, something new learned...

It clashes with common/str.cpp and produce a crash, but nevermind.

Shared Objects Crash

What could/should i look at next to see and maybe find why the shared objects build is crashing on loading a game (and ultimately on loading in a shared object engine)?

ResidualVM

Just curious:
Take a look here:
https://github.com/residualvm/residual ... facesdl-graphics.cpp#L439

If i set bpp to either 8 or 24 in residualvm.ini, i get that exact error message.
Quote:

WARNING: Unsupported bpp value: 8! (or 24)
WARNING: SDL_SetVideoMode failed: Invalid texture!

Why?
I thought 8, 16, 24 and 32 bpp were supported on AmigaOS4?

EDIT: I see, that is only if i use the Softw3are renderer...intriguing

It's ResidualVM who doesn't support 8 or 24 bpp. Are you 100% Residual is meant to work with 8/24 bit?

I would add debug traces close to the crash site (before the crash line) if the root cause is somehow non-obvious.

Mostly stupidity, mixed with a little bit of c&p mistakes and lots of missing night sleep...

I can't reproduce the (str.cpp) crash anymore and i have another debug output ready, salass00 was right.
Right before it should load the game it hits an IDOS: 0x0000000.

Also, i made an exhausting post over at Hyperion with all the information gathered in one place, maybe you want to continue there, since this thread seems to get derailed?

@Raziel
You may remember it, or may not : but when i release Barony game port , there was some strange crashes too : they was exactly because of IDOS 0x00000000. To fix them, i just open dos.library (together with IDOS interface up) in the place where crashes happens (i.e. via stack trace build with -gstab check in which source file it crashes, and there add opening / closing of dos.library with interface).

Just like that:


//somewhere at begining of function

#ifdef __amigaos4__    

    DOSBase=IExec->OpenLibrary("dos.library",0);

    IDOS = (struct DOSIFace *)IExec->GetInterface(DOSBase, "main", 1, NULL);

#endif



// original code



// at end of function, right before return 0 if it will be there, just at end so it closes

#ifdef __amigaos4__

    IExec->DropInterface((struct Interface *)IDOS);

    IExec->CloseLibrary(DOSBase);

#endif

For Barony i had to do it in 2 places, and it wasn't "sobjes" but statically compiled.

And i do not know of course if it will fix your issues, but just all of this remind me my ones i have with Barony port.

It's ResidualVM who doesn't support 8 or 24 bpp. Are you 100% Residual is meant to work with 8/24 bit?

Of course not

I'm unsure in everything i do or know

@kas1e

Uhh, sweet...an easy enough solution for me to try.

Hmm, well, the two lines where it crashes are 82 and 88, so i'll try those first.

But, wouldn't this be a bug in ScummVM's Amiga part then?
Or even a bug in the system itself?
Or could it be simply that ScummVM's Amiga part is old enough to have outlived the coding necessaties of the current system?

/me gives kas1e a kiss

That did it...preliminary test though, but at least i can start games without crashing with ALL the engines in place.

Thank you

I still have to test if anything bad happens when building static, but i guess not.

Thank you, thank you, thank you, thank you
