Perhaps "libinkview.so" was linked to a different "libcurl.so" than the one my compiler uses, or what's up here?

Please, follow all the steps I specified in my previous post... Use my SDK, not pocketbook original, set up 32-bit libs from ubuntu 10.04 or 10.10 and do the rest steps. Everything should work fine.

You may loook to my post at russian forum http://www.the-ebook.org/forum/viewt...=703698#703698
for list of ubuntoo libraries you need and aditional LD_FLAGS (or look at my ebuild, more you need is at src_unpack function). It seams that ubuntoo libraries are not binary compatible with some other distributives.

Hi,

I'm trying to get into programming with sergeyvl12's unofficial SDK.

Almoust everything is working fine and I was able to compile the example apps with the "BUILD=arm_gnueabi" switch and run them on my PB903.
Great work, sergey! Thanks!

The problem I have now is that I would like to use "BUILD=emu" to test the apps locally on the PC, before copying them to the reader via USB, since it is really annoying to connect the USB cable, copy the app, disconnect the device again and run the app on the reader each time I made some changes to the code.
However, if I try to build the app with the emu-switch, it will compile without any errors, but as soon as I'm trying to run the app on the PC, I'm getting a bunch of error messages:

root@dragon: /home/test/projects/grays/obj_emu# ./grays
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
Segmentation fault

My PC is running Debian 32bit version (debian-6.0.2.1-i386) and I have installed the latest version of the custom SDK the way sergeyvl12 described it in his initial post.

Any help or suggestions how to get the emu-thing working would be highly appreciated.

Go into the obj_emu directory, delete any system directory there, and then make a soft link to the system directory in the pocketbook installation directory:

ln -s /usr/local/pocketbook/system .

Or run your application in the /usr/local/pocketbook directory. It seems that the i386 version of libinkview.so looks for everything in ./system/

Thanks for your reply. I've tried each one of your options but neither one worked for me

[rkomar]

So, does the command:

ls ./system/fonts/

show the LiberationSans fonts as being there?

Yes, if I copy the compiled file grays to /usr/local/pocketbook, all the fonts are there when typing the above command, also LiberationSans.ttf and LiberationSansBold.ttf.

After fiddling around for nearly the whole day trying out different stuff, I've finally found out what the problem was! Now I can run the inkview program for example.

If someone else has the same problem, here's the solution: It seems to me that some files where missing in the system directory after installing the unofficial version...(at least in my case)...Not sure why this is, I'll have to check that some day when I have more time. I downloaded the PBSDK, copied the contents of system to the /usr/local/pocketbook directory while leaving the commons.mk file intact and now it's working just perfectly fine with the emulator after copying the compiled program to /usr/local/pocketbook. Thanks for your help. That got me on the right track.

Hi!

No need to copy the compiled file somewhere.

The solution is simple:

1. Suppose you are in the obj_emu and compiled file is in this directory;
2. rm -rf system
3. ln -s /usr/local/pocketbook/system .
4. You can run your program from this directory ./program:

That's all...

You don't need additional files

Just, the directory from you run your program (current working directory) must contain "system" - link or copy of /usr/local/pocketbook/system.

P.S. Interesting thing. I still don't receive notifications fron this thread...

I modified the common.mk file to make the soft link automatically. I also changed it to define "IVSAPP", since the i386 version of libinkview.so seems to look for everything in ./system. Here's a patch for my changes.

I don't think that I receive notifications for these, either.

Edit: Strike that. I did get a notification for this thread last night. Don't know why you are not.

This will be in the next version of SDK soon.

pbsdk-1.0.7 released!
1. "system" link (thanks rkomar)!
2. ssl libs needed for links building for 3xx added to arm-linux;
3. Removed unneeded deps from inkview.h and common.mk;
4. IVSUPP flag added for emu.

[pbmaniac]

It seems that my system didn't find the libinkview.so in the lib32 directory, so I copied the file from this location to the /usr/local/lib directory. Afterwards, everything worked like a charm. Probably something wrong with my Debian installation

[read365]

"BUILD=arm_gnueabi" is working Great, sergeyvl12 Thanks!
The problem I have now is that I would like to compile "BUILD=emu"

when i compile...

~/workspace/src/pb/inkdemo$ sudo make BUILD=emu
gcc -c -o obj_emu/inkdemo.c.o -D__EMU__ -DIVSAPP -Wall -g -m32  -MTobj_emu/inkdemo.c.o -MF`echo obj_emu/inkdemo.c.o | sed -e 's,\.o$,.d,'` -MD -MP inkdemo.c
In file included from /usr/include/sys/ioctl.h:27:0,
                 from inkdemo.c:5:
/usr/include/bits/ioctls.h:24:24: fatal error: asm/ioctls.h: file not found
compilation terminated.
make: *** [obj_emu/inkdemo.c.o] error 1

i'm using debian_wheezy amd64

how can i working "BUILD=emu"...??

[rkomar]

@read365: It looks like you are missing the kernel header files on your system. In Ubuntu, you need to add a package called something like "linux-libc-dev". It's probably named something similar in debian.
