Compilling Pidroid for Android.

[Krzysztof Klinikowski]

Okay. I want to start writting UI for Pidroid (http://
csclub.uwaterloo.ca/~dtbartle/pidroid/) but I have problem with
compilling it properly. So how I'm doing it? Simply:

1. First I define new PATH to use arm-eabi-gcc and scripts for pidroid
from ./pidroid/cmds (mydroid is a compiled android platform, version
2.2)

export PATH=$PATH:/home/kkszysiu/Pobrane/pidgin_android/pidroid/cmds/:/
home/kkszysiu/Pobrane/android-sdk-linux_86/tools/:/home/kkszysiu/
mydroid/prebuilt/linux-x86/toolchain/arm-eabi-4.3.1/bin/

Later I just type make in the pidroid dir and it compiled well, I just
made one small change in ./pidroid/libpidroid/libpidroid.h, changing:

#include <utils/IBinder.h>
#include <utils/IServiceManager.h>
#include <utils/Parcel.h>

To:

#include <binder/IBinder.h>
#include <binder/IServiceManager.h>
#include <binder/Parcel.h>

Because binder is a standalone library now.

Now in ./pidroid/assets I have libtarxz.so and pidroid.tar.xz.
I got apk file too but when I upload it into emulator/phone I always
got in adb logcat:

D/PidroidApp( 374): [BuddyList.onCreate]

Question is why? And how to make it work. Theres some debug messages:

Any idea what's wrong?

[Doug Kwan (關振德)]

You need to install libicuuc somewhere that is visible to the
toolchain. The configuration failed becasue the linker cannot find
the iccuc library.

That's really important. You need to know that mydroid is a downloaded
and compiled android platform from where I got a lot of other
libaries.

I figured out how to make it work too. Propably Android 2.2 version
has changed somthing and backward compatibility beetween 2.1 and 2.2
is just theoretically ;) On Android 2.1 I runned it successfully after
some changes in code but I got some problems beetween C/Java binder
connection ;) "Bad magic number" error or something. Soon I will post
somewhere how to do that and some instructions/howtos and maybe we
find some developers then we made good Android IM that's just suck
less ;)

Krzysztof

Which means you're probably linking against unstable system libraries. Don't be surprised if things don't work consistently between platforms if you don't use the NDK-provided libraries for linking.

I don't have libraries like MPFR and GMP in NDK so that's pretty hard
to link that from NDK ;)

You should be able to rebuild them with the standalone toolchain in r5, then expose them as prebuilt static library modules though.

These libraries are not provided by the platform though, so as long as you statically link to them, or include them in your .apk, you should be good.

Sorry for the over-reaction :-)

Okay. I'll try to do that when I back from work to home then maybe I
will create github repo with my changes :)

Hmm,
Looks like you have system restrictions on your enviroment or
something. Do you have root access on that machne? Like for me it
looks like You dont have permissions to execute ant. You could give a
path to tools dir from your SDK directory in your PATH variable :P

Well, ant wasn't installed yet... x/

Now I am at the status of your first message.

Is the libtarxz.so on the (virtual) device and only fails to load or
is it just not on the device?

Do you know what of Pidroid already works concerning the UI? What
would we see if the libtarxz.so would load? :-)

[Krzysztof Klinikowski]

NOt just on the device. I removed all that libtarxz.so stuff from my
version and I'm using pure libpidroid.so ;P UI is not writen now. For
now we see just buddylist concept with progressbar ;P
