[fpc-pascal] Re: Strange arm-linux cross-compilation errors

2011-04-12 Thread herux 
I think we should change the file crt0.as, as described in the following link 
http://honeypod.blogspot.com/2007/12/initialize-libc-for-android.html


I have not done so, I'm doing another job first.

[fpc-pascal] android share library with classes unit

2011-04-12 Thread herux 
I managed to compile and run the library for android on emulator, which I
compile the project just a libhellojni.so

compile using paramater like this

ppcarm -Scghi -O1 -Parm -gl -b -B -XX -Xc -XD -CpARMv6 -CfSOFT -dandroid 
-vewnhi -l -XParm-linux-
-Fi/home/herux/workspace/hellojni/jni/lib/arm-linux/ -Fu. -FUlib/arm-linux/
-o../libs/armeabi/libhellojni.so -FD/usr/share/fpcsrc/binutils/ 
hellojni.lpr

on Kubuntu 10.04 x86_64

library code:

library hellojni;
{$ ifdef fpc}
  {$ mode delphi}
{$ endif}

uses
 JNI, log;

Java_com_herux_hellojni_MainActivity_Hellojni function (env: PJNIEnv; Thiz:
jobject): jstring; cdecl;
begin
   result: = env ^. NewStringUTF (env, PChar ('Hello JNI from FreePascal
..'));
end;
exports
Java_com_herux_hellojni_MainActivity_Hellojni name
'Java_com_herux_hellojni_MainActivity_Hellojni';
begin
end;

then I try to use classes unit or sysutils, the project succeeded in
compiling, but the library did not loaded by the emulator. there is an error
SIGSEGV

I use this binutils http://www.gnu.org/software/binutils/
using this command to build crosscompiler

make clean crossinstall CPU_TARGET=arm OS_TARGET=linux
CROSSBINDIR=/usr/share/fpcsrc/binutils/ OPT="-dFPC_ARMEL -O- -gl"
CROSSOPT="-dANDROID -CpARMv6 -gl -CfSOFT -O-"

I may have to repeat it

[fpc-pascal] Re: android share library with classes unit

2011-04-13 Thread herux 
My problem is resolved, I apply the patch contained in that link. reported by
Dejan Boras.
then rebuild cross compiler with this:

make clean crossinstall CPU_TARGET=arm OS_TARGET=linux
CROSSBINDIR="/usr/share/fpcsrc/binutils" OPT="-dFPC_ARMEL -O- -gl"
CROSSOPT="-dANDROID -CpARMv5 -gl -CfSOFT -O-"

now it's work. libhellojni.so loaded succesfully.

thanks

[fpc-pascal] android JNI JString to String

2011-04-26 Thread herux 
I have a strange problem, I pass data from the android String via JNI. pass
data from FreePascal wideString successfully using the following code

NewString: function (Env: PJNIEnv; const Unicode: PJChar; Len: JSize):
JString; cdecl; 
GetStringChars:function(Env:PJNIEnv;Str:JString;IsCopy:PJBoolean):PJChar;
cdecl;

function JNI_WideStringToJString(Env: PJNIEnv; const WStr: WideString):
JString;
begin
  Result := Env^.NewString(Env, Pointer(WStr), Length(WStr));
end;

but when passing data JString to widestring, using this code :

function JNI_JStringToWideString(Env: PJNIEnv; JStr: JString): WideString;
var
  IsCopy: JBoolean;
  Chars: PJChar;
begin
  if (JStr = nil) then begin
Result := '';
Exit;
  end;

  Chars := Env^.GetStringChars(Env, JStr, IsCopy);
  if (Chars = nil) then begin
Result := ''
  end else begin
Result := WideString(Chars);
Env^.ReleaseStringChars(Env, JStr, Chars);
  end;
end;

return only 1 character leading. 
if anyone has ever experienced ? or there's something wrong with JNI header
?

thanks

Re: RE : [fpc-pascal] android JNI JString to String

2011-04-26 Thread herux 
thanks for the response.

I am doing what you suggest. but it's still the same.

I debug this line of code using android log

Chars := Env^.GetStringChars(Env, AJString, nil);
__android_log_write(ANDROID_LOG_DEBUG,'proj_debug',PChar(Chars)); 

and the log I retrieved :

04-26 17:53:17.942: DEBUG/proj_debug(711): e <--- only "e" character

from input AJString =
eNp9zt0KwjAMBeBXCecBrApeCEmG+iRzdrX+dKMrMn16Y0G8M5Cr75ATbub7jR4+T3FIgtViiUa5VS5xGPsfrA2c8lG5o5NghrJX7ikInqCzYCo5pgCKgq3NJ1x1+KuvqjEVH3yuXGuc3b4oX2knAO2tfgM6fNHEdbb2jGv1DUfmNOA=

so I thought, this is not about that. but I do not know why

[fpc-pascal] compiling turbo power lockbox on ubuntu 64

2011-07-26 Thread herux 
Hi,
I use RSA encryption library lockbox turbo power.
in a windows environment I managed to compile and the apps working well, I
use {$ mode delphi}. 
but when I compile it on ubuntu 64bit, there is an error when compiling


component/LockBox/LbCipher.pas(708,10) Error: Unknown identifier "EBX"
component/LockBox/LbCipher.pas(708,10) Warning: No size specified and unable
to determine the size of the operands, using DWORD as default

component/LockBox/LbCipher.pas(712,14) Error: Unknown identifier "AH"
component/LockBox/LbCipher.pas(713,13) Error: Unknown identifier "EBX"
so on ...

asm delphi like code doesn't compiled right ? but why on windows compiled ?

I am trying to cross compile it in windows, for linux x86_64, and produces
the same error.
whether the asm code is not supported for 64bit?

yes, I think you're right. better to write it into native.

Try using Indy or Synapse as HttpClient to send data content  using HTTP POST

I guess this is not a limitation of HTTP, just not the standard for web
