Pocketbook SDK, Linux and Wine

[mikmak]

Hi,

I'd like to try out the sample applications in the Pocketbook SDK. I compiled both "grays" and "inkdemo", but if I run them I get the following error:

grays$ ./grays.exe
hwnd=65584
FT_New_Face: cannot open LiberationSans-Bold
FT_New_Face: cannot open LiberationSans
FT_New_Face: cannot open LiberationSans-Bold
FT_New_Face: cannot open LiberationSans-Bold
FT_New_Face: cannot open LiberationSans-Bold
FT_New_Face: cannot open LiberationSans-Bold
FT_New_Face: cannot open LiberationSans-Bold
wine: Unhandled page fault on read access to 0x00000018 at address 0x7ee1d816 (thread 0009), starting debugger...

Versions:
wine-1.1.31
gcc (Ubuntu 4.4.1-4ubuntu8) 4.4.1

I know this is not really a dev forum, but the Ukrainian one was not of much help (using google translate). Maybe someone used wine to run some Pocketbook apps already...

Thanks,
Michael

I've got the same problem, but no solution.
I successfully run some applications with the previous version of the SDK but none with the latest (14.2) :/

Hi,
thanks for the reply... do you remember which version or do you have it still lying around somewhere?

[logan]

I think it was the SDK 12.5.

You could grab it here:
http://sourceforge.net/projects/pocketbook-free/files/

[mikmak]

Ah, ok thanks. I didn't see that older versions are available there... I'll give it a try and maybe I can figure out the differences to the current version...

[mikmak]

Ok, I experimented a bit but no solution. Also 12.5 crashes with exactly the same error.

Do you remember which gcc and wine version you used with SDK 12.5?

From the look of the message, looks like you need to install some fonts in wine.

[mikmak]

They are installed...

I use the gcc embedded in the SDK, don't I?

~/PBSDK-linux-libwine-12.5/bin/arm-linux-gcc --version
arm-linux-gcc (GCC) 3.4.1
..

I was using win 1.0 and upgrade recently to wine 1.1.31 but that didn't make any difference.

I notice an important fact: in several files, SDK refers to "/usr/local/pocketbook" as the SDK root. I've create a symlink to point on my SDK location. Removing it, I can't launch any application on SDK 12.5.

sudo ln -s ~/PBSDK-linux-libwine-12.5 /usr/local/pocketbook

I hope it will help you

Yes, that's the compiler used for the ARM target (the Pocketbook).
But for the PC, winegcc is used, which in turn uses the compiler you have installed for x86 architectures. You can easily check that by adding the -v flag to the Makefile rule:

$(OUT): $(CFILES) $(IMGSRC)
        $(CC) -v -o $@ $^ $(INCLUDE) $(LIBDIR) $(LIBS) $(CFLAGS) $(WINEFLAGS)

Man, thanks! That was it... 12.5 works now for me if I create this symlink (quite stupid to have to have that, but whatever).
14.2 still crashes with the same error, but now I can at least figure out what has changed between 12.5 and 14.2 to triage the fault (maybe).
I will come back to that later in the evening...

Ok, I was impatient and digged a bit:

In 12.5:

inkview.h has

#if !defined(__CYGWIN__) && defined(__i386__)
#  define DIRPREFIX "/usr/local/pocketbook"
#else
#  define DIRPREFIX ""
#endif

and

$ grep -r "/usr/local/pocketbook" *
arm-linux/include/inkview.h:#  define DIRPREFIX "/usr/local/pocketbook"
include/inkview.h:#  define DIRPREFIX "/usr/local/pocketbook"
Binary file lib/libinkview.a matches

So libinkview.a in 12.5 has DIRPREFIX properly defined due to the #ifdef in inkview.h

In 14.2 it looks different:

inkview.h

#ifdef __WINE__
# define DIRPREFIX "/usr/local/pocketbook"
#else
# define DIRPREFIX ""
#endif

and

$ grep -r "/usr/local/pocketbook" *
arm-linux/include/inkview.h:# define DIRPREFIX "/usr/local/pocketbook"
include/inkview.h:# define DIRPREFIX "/usr/local/pocketbook"

Here, libinkview.a does NOT have DIRPREFIX defined, probably because it was not compiled with winegcc (which sets __WINE__).

I'll ask Forkosigan to forward this to the developers...
