Hi,

I build pbc on Mac OS X 10.7 with Android NDK r7b. There are two problem:

1) ./configure --host=arm-linux-androideabi  Stopped, when change the ./config.sub ./config.guess, it passed.

2) ./make will stopped with the following message

libtool: compile:  /Users/guanzhi/Code/android/ndk-r7b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/darwin-x86/bin/arm-linux-androideabi-gcc --sysroot=/Users/guanzhi/Code/android/ndk-r7b/platforms/android-9/arch-arm -DHAVE_CONFIG_H -I. -Iinclude -Wall -W -Wfloat-equal -Wpointer-arith -Wcast-align -Wstrict-prototypes -Wredundant-decls -Wendif-labels -Wshadow -pipe -ffast-math -U__STRICT_ANSI__ -std=gnu99 -g -O2 -MT libpbc_la-extend_printf.lo -MD -MP -MF .deps/libpbc_la-extend_printf.Tpo -c misc/extend_printf.c  -fPIC -DPIC -o .libs/libpbc_la-extend_printf.o

misc/extend_printf.c: In function 'do_print':

misc/extend_printf.c:75: error: incompatible type for argument 3 of 'fstrcb'

misc/extend_printf.c:75: note: expected 'va_list' but argument is of type 'void *'

 

I commit this line and pass the make process and get the pbc command line tool, which can be

adb push

to my Nexus S (2.3.6) and work.

I am not sure if this will happen on Android NDK with other version or on other OS.

Thanks.

Hi,
I build pbc on Ubuntu also with Android NDK r7b.The same problem
apprears:

Can you try replacing extend_printf.c with the one I've attached? Please let me know if it works.

Hi Ben:
   I have replaced the extend_printf.c file and tried it agein.
But I feel so sorry that errors occur as follow:

  Obviously,there is not the printf.h file.So I copied the printf.h
under /usr/include/printf.h to $NDK/android_armeabi/sysroot(my
own sysroot) and  then tried it again. A lot of errors occured,

Hi
       Thanks! I have succeeded to install PBC with Android NDK.
I am curious about the reason why I failed the first time. Then
I compared the original extend_printf.c with the one you gave
me.I found that you have changed the type 'va_list' to 'void*' in
the  parameters of  function  'format_cb'. Now I know the meaning
of the error

 misc/extend_printf.c:75: error: incompatible type for argument 3 of
'fstrcb'
misc/extend_printf.c:75: note: expected 'va_list' but argument is of
type 'void *'

      But I still have a question.Why must change if want success.
I succeeded to install PBC on my  Ubuntu system without any change.
Could you tell me the reason or recommend some references for me.
      Thanks for giving me so much help.

It's an old bug; I wrote that file in a hurry. I never cared much about the quality of the printf extensions because I only used them for logging statements. Ideally I'd like to use reigster_printf_specifier() but that only seems to be available on certain platforms.

I'm guessing my bug didn't matter on Ubuntu because va_list just happens to be a void *.

Hi Zhao,
How did you compile the PBC on android? Did you write an Android.mk?
Please help me, I also want to use it on Android.
Thank you :D

Hello?

Am working on the project where data is encrypted at the server and then
decrypted on Android smart phone. I have a fully working application.
However, one of the challenge am facing now is how to measure the
computation performance at the server and mobile device. I want to
know the time it takes to encrypt (at the server) and decrypt (at the
mobile device).

Kindly help me on how to go about this....

Many thanks

Richie

Hi Richie,
How did you compile the pbc on Android? And how to write the pbc
Android.mk?
I also want to decrypt/encrypt files in Android, but don't know how to
do it with Android ndk.
Would you help me?
Thank you very much.

I think pbc_get_time may help you.

The function prototype is

    double pbc_get_time(void);

And the function is at:

     

     #include <pbc/pbc_test.h>

You may:

     t0 = pbc_get_time();

     //  some code

     t0 = pbc_get_time() - t0;

     // now $t0$ is the time cost of "some code"

    Cheers,

    Homer

Hi Ken:
Here is my Android.mk.

--------------------------------------------------------
LOCAL_PATH := $(call my-dir)

## prebuilt the static libs
include $(CLEAR_VARS)

LOCAL_MODULE := libgmp
LOCAL_SRC_FILES := libgmp.a

include $(PREBUILT_STATIC_LIBRARY)

## prebuilt the static libs

LOCAL_MODULE := libpbc
LOCAL_SRC_FILES := libpbc.a

LOCAL_STATIC_LIBRARIES := libgmp

include $(PREBUILT_STATIC_LIBRARY)

LOCAL_MODULE    := hello-jni
LOCAL_SRC_FILES := hello-jni.c

LOCAL_WHOLE_STATIC_LIBRARIES:= libgmp libpbc

LOCAL_LDLIBS := -llog

include $(BUILD_SHARED_LIBRARY)
-------------------------------------------------------

because of pbc depending on gmp,so it need to use
LOCAL_WHOLE_STATIC_LIBRARIES, or you will
meet the problem as I countered.

Hi

I also need to run pbc on Android. I got a precompiled version of GMP from https://github.com/Rupan/gmp and I compile pbc using the ndk toolchain.
As soon as I try to initialize a pairing the whole Android application just exits.

Have any of you encountered this problem? Do any of you have a suggestion? Should I rather compile GMP myself with the ndk toolchain?

Yes, and I have exactly the same problem. Unfortunatly I don't know any solution. If you find one I'm interested.

I compiled GMP using the NDK standalone toolchain, and I know it works as I use it for another application. But no luck with PBC.

I got PBC going on Android, but it only works on the emulator for some odd reason. The app just quits on the device. I will keep you posted on my progress. Have any of you encountered this problem?

How did you compile GMP? I've got PBC working, it works on the emulator but not on a real device. I think my GMP is not compiled correctly as the program seg faults at mpz_divexact(z, deg, fac).

Not *that* odd.  I'm pretty sure the emulator is intel and your phone is arm.  Arm is wrongendian and the binary header is going to be wrong.

If byte order is an issue, the only option is source diving and patching (likely original coder assumptions, aka bugs).

If the problem is just the binary headers and linking, ... well, ... welcome to the painful world of cross compilers.  Once you get the hang of it, it's not too bad, but it won't be easy at first.

Ok so I've finally managed to get everything working. GMP cross compiles fine, the problem was with PBC and Android's flavour of GCC.

Android's flavour of GCC does not support the uses of nested functions. I had to copy the function, in param.c, <code> const char* lookup(const char *key, void* tab) </code> out of the function <code> static int param_set_tab(pbc_param_t par, symtab_t tab) </code> and do some refactoring.

I stumbled on this patch for OSx on PBC 0.5.4 http://ds.informatik.rwth-aachen.de/members/bitsch/pbc-0.5.4-osx.patch/view that led me to patching the PBC code for Android.

I don't know if the patch in the link was ever submitted to PBC, but I will definitely bring it to Ben Lynn's attention.

I hope this helps some people out there.

This helped me and saved my time a lot.

A bit of clarification on Steyn Geidenhuys's posting: the problem happened on a real phone, not on an emulator or during compilation. Compilation worked fine with ndk n8, and I could make pbc work within emulator. However, as soon as I moved the app to real devices, calls to nested lookup() functions failed with SIGSEGV with faulting address being the function address of lookup function. Once I patched pbc with the OSX patch, it worked fine.
