How to write an app for Pocketbook?

[cotr]

Hello,

I read some of the threads in here. And I search somethings via Google but I can't figure out how can I begin to write my app for Pocketbook. Can anyone write a roadmap for from scratch?

I am a web developer, I know JS, PHP, PYTHON. So if its possible with that language. If it's not possible what should I learn?

In terms of a roadmap, there isn't anything official. Your best bet is to look at the inkview.h file in the SDK to see what the API functions are. Looking at the code of working applications is also a big help. There are some example applications within the SDK. There are also some third-party applications whose source code is available. Search this forum and you should be able to find some of those. If you have specific questions, you can ask them here, and someone may know the answer to it.

The PocketBook devices are linux systems. You can use the SDK to cross-compile software for those systems and then install it in internal memory or on the SD card. You could probably build python for it if you were so inclined.

Python source: https://www.python.org/ftp/python/3....n-3.5.2.tar.xz
SDK: https://github.com/blchinezu/pocketbook-sdk

Build instructions for Linux with SDK_481 (FW5):

- Get the SDK and put it in your home dir ~/
- Get the python source, extract it and put the dir in ~/PBDEV/sources
- Extract the attached pocketbook-build.sh.zip and put the script in ~/PBDEV/sources/Python-3.5.2
- run the script

Or you could just try the build I attached. I didn't test it but I suppose it should work.

If you like to try without installing and configure you should take a look here: https://www.mobileread.com/forums/sho...d.php?t=224164

When I try this I get the following after "make python":

arm-obreey-linux-gnueabi-gcc -c -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrap
v -O3 -Wall -Wstrict-prototypes -Werror=declaration-after-statement -I. -IInclu
de -I./Include -DPy_BUILD_CORE -o Programs/python.o ./Programs/python.c
as: loadlocale.c:130: _nl_intern_locale_data: Assertion `cnt < (sizeof (_nl_value_ty
pe_LC_TIME) / sizeof (_nl_value_type_LC_TIME[0]))' failed.

with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
make: *** [Makefile:773: Programs/python.o] Error 4

It's no priority for me to compile python especially, because I intended to compile mg, ssh and such, but I wanted to understand the procedure and I'm not sure how to do properly.

Using C++ I got:

collect2: error: ld terminated with signal 6 [Aborted], core dumped
ld: loadlocale.c:130: _nl_intern_locale_data: Assertion `cnt < (sizeof (_nl_value_type_LC_TIME) / sizeof (_nl_value_type_LC_TIME[0]))' failed.
make[2]: *** [CMakeFiles/HelloWorld.app.dir/build.make:129: bin/HelloWorld.app] Error 1
make[2]: Leaving directory '/home/johann/Dokumente/Repo/Github/Pocketbook-HelloWorld'

make[1]: Leaving directory '/home/johann/Dokumente/Repo/Github/Pocketbook-HelloWorld'
make: *** [Makefile:130: all] Error 2

and fixed it setting
LANG=/usr/lib/locale/en_US

Might also help in your case.
