I have used QCA (qca-2.0.1-mingw) library for encryption.
I have searched some code and write into the application. But it does not support the AES encryption standard.
e.g
QCA::supportedFeatures();
QCA::isSupported("aes128-cbc-pkcs7");
shows the o/p
("random", "md5", "sha1", "keystorelist")
false
Why AES is not supported ?
Thanx.. Frank and elmigranto
now, i have download qca-ossl-2.0.0-beta3 form link and also install the OpenSSl(Win32OpenSSL-1_0_0j.exe).then i build it by follows this link
configwin rd
Configuring for release and debug, dynamic
Wrote conf_win.pri
qmake
C:\qca-ossl-2.0.0-beta3>qmake
'qmake' is not recognized as an internal or external command,
operable program or batch file.
Also when i build the qca-ossl.pro file it shows o/p as:
c:\qca-ossl-2.0.0-beta3\qca-ossl.pro:17: warning: Unable to find file for inclusion winlocal.prf
what to do next? pls help me guys..

I am testing google closure compiler on command line.
I took the latest version :
java -jar closure-compiler.jar --version
Closure Compiler (http://github.com/google/closure-compiler)
Version: v20190618
Built on: 2019-06-21 17:24
I am generating a compressed version of my javascript like this :
java -jar closure-compiler.jar my_script.js > out.js
The problem is that the generated code is bigger than the one I get when I use the online service at https://closure-compiler.appspot.com/home
I noticed that the command line version added, at the beginning, the following code :
var $jscomp=$jscomp||{};$jscomp.scope={};$jscomp.findInternal=function(a,c,b){a instanceof String&&(a=String(a));for(var d=a.length,e=0;e<d;e++){var f=a[e];if(c.call(b,f,e,a))return{i:e,v:f}}return{i:-1,v:void 0}};$jscomp.ASSUME_ES5=!1;$jscomp.ASSUME_NO_NATIVE_MAP=!1;$jscomp.ASSUME_NO_NATIVE_SET=!1;$jscomp.SIMPLE_FROUND_POLYFILL=!1;
$jscomp.defineProperty=$jscomp.ASSUME_ES5||"function"==typeof Object.defineProperties?Object.defineProperty:function(a,c,b){a!=Array.prototype&&a!=Object.prototype&&(a[c]=b.value)};$jscomp.getGlobal=function(a){return"undefined"!=typeof window&&window===a?a:"undefined"!=typeof global&&null!=global?global:a};$jscomp.global=$jscomp.getGlobal(this);
$jscomp.polyfill=function(a,c,b,d){if(c){b=$jscomp.global;a=a.split(".");for(d=0;d<a.length-1;d++){var e=a[d];e in b||(b[e]={});b=b[e]}a=a[a.length-1];d=b[a];c=c(d);c!=d&&null!=c&&$jscomp.defineProperty(b,a,{configurable:!0,writable:!0,value:c})}};$jscomp.polyfill("Array.prototype.find",function(a){return a?a:function(a,b){return $jscomp.findInternal(this,a,b).v}},"es6","es3");
I do not have such a code in my script: Where does it come from ?
how can I produce the same output as the online version ?
To get the compiler command line work as the web service, I just added an option :
--language_out=ECMASCRIPT_2015
This is likely a discrepancy between the settings on the web service and the ones you're using locally.
Have a look at a Closure Compiler: Flags and Options to see what settings you might prefer.
If you'd share your source, it'd be possible to try and help you narrow down the options.
As for the extra code, I believe it is at least partially a polyfill for Array.prototype.find (aka [].find), which I assume is in your code?
If so, that's Closure injecting code to improve your cross browser compatibility.
I am a new user of Ocaml-java (or Cafesterol) which compiles primtive Ocaml program to executable jar that is allowed run on JVM. However when I try to compile a test program into executable jar I got error info as follow:
>java -jar ~/ocaml-project/ocamljava-bin-1.4/bin/ocamljava.jar -standalone regexdna.ml -o regexdna.jar
File "regexdna.ml", line 1, characters 0-1:
Error: No implementations provided for the following modules:
Str referenced from regexdna.cmj
Unix referenced from regexdna.cmj
It seems module Str and Unix is missing from Ocaml-java. However, str.jar and unix.jar do exist under ~/ocaml-project/ocamljava-bin-1.4/lib/others/ when I install Ocaml-java, and within these jars we do have Str.class and Unix.class. (I suppose this directory is on the path of the standard library of Ocaml-java, so it should be included in default search path)
Can any Ocaml-java user tell me how Ocaml-java search for dependency libraries?
Quoting Xavier Clerc on this :
Well it should work, but you have to pass explicitly the referenced
library (just as in vanilla OCaml). Leading in your case to:
$ /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java -jar ~/opt/ocamljava-2.0-early-access9/lib/ocamljava.jar str.cmja regexdna.ml
Note that I am using the latest ocamljava preview.
If you see my other question, you will now better my goals. Take a look at: https://stackoverflow.com/questions/19510039/from-regex-to-parser-generators .
As I'm trying to be a good boy, I'm reading the README (see https://java.net/projects/javacc/sources/svn/show/tags/release_60/examples/SimpleExamples?rev=555 ).
Run javacc on the grammar input file to generate a bunch of Java files that implement the parser and lexical analyzer (or token
manager):
javacc Simple1.jj
Now compile the resulting Java programs:
javac *.java
The parser is now ready to use. To run the parser, type:
java Simple1
My try:
D:\tests\javacc\simple1>javacc ..\Simple1.jj
Java Compiler Compiler Version 6.0_beta (Parser Generator)
(type "javacc" with no arguments for help)
Reading from file ..\Simple1.jj . . .

File "ParseException.java" does not exist. Will create one.
File "Token.java" does not exist. Will create one.

Parser generated successfully.

My java version:
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) Client VM (build 24.45-b08, mixed mode, sharing)
I'm sure that "these" guys known what they are doing, I'm sure I did something wrong, but what? Getting a simple error like that in the first test with javacc?
How can I fix that and continue my lecture?
I suggest using version 5.0 for now. There are a lot of changes in version 6 and these came along with some bugs. There should be an update to version 6 soon. https://java.net/projects/javacc/downloads
Will you put the code to look it or your complete call. I think, that it´s a code error or that you call a bad .java archive. For example:
I have: Mytokens.jj and javaCode.java ok? Good, you need said:
javacc Mytokens.jj
javac javaCode.java
java javaCode <test1.txt>
I give you my *.bat for the test. You create a new txt and write it:
CALL javacc nameJJ.jj
#pause
CALL javac NameJava.java
#pause
java NameJava <prueba1> salida.txt
type salida.txt
#pause
This do the test for you when you do a double-click on it if you have a copy in your javacc/bin and your practice directories.
I am am unable to get avr-elf-windows and WinAVR to work. I have managed to build the example supplied with avr-elf-windows (ATmega2560). But if I try and expand to use another chip or start using the WinAVR supplied packages and projects I keep getting errors I cannot work out.
Method 1:
Modify the ATmega2560 example to use the WinAVR packages.
Changed:
with Atmega2560; use Atmega2560;
to:
with AVR; use AVR;
with AVR.Atmega328p; use AVR.atmega328p;
Create a project file to include:
with "C:\WinAVR-20100110\lib\gnat\avr.gpr";
with "C:\WinAVR-20100110\lib\gnat\avr_app.gpr";
Running make I get the following error:
avr-gnatmake: "C:\WinAVR-20100110\lib\gnat\avr_lib\avr-int_img.adb" compilation error
Great, I have a compilation issue, but I cannot see the error.
Method 2:
Open the above project file in GPS. Change the build setting to be gnatmake. GPS now starts reporting errors and warnings:
Project warning: object directory "avr_lib/avr5/obj" not found
Project library directory "C:\WinAVR-20100110\lib\gnat\avr_lib\avr5\lib\" does not exist
The latter issue is very clearly the fact that I have not set up GPS correctly to tell it the values of microcontroller and architecture, but I cannot seem to find anything to resolve this.
Method 3:
To use the WinAVR set up directly using makefiles which then gives me the error:
avr-gnatmake: RTS path not valid: missing adainclude and adalib directories
If I follow the instructions I can find by searching the web I can only find details for building the required libraries under Linux.
Platform: Windows 7.
With the combination of the two answers above I have now managed to link my sample code. As to wether it will work on the Arduino, that is a different issue.
Many thanks for the help.
I have found it a bit frustrating to get this far, and I wonder if there are others out there who may just give up on Ada on the Arduino and go back to the Arduino IDE and therefore missing out on the opportunity to learn a language with more structure. There are many misleading pages out there that also do not help.
You might want to take a look in the paper Integrating 8-bit AVR Micro-Controllers in Ada. Basically you can use a GPS project file arduino.gpr like
project Arduino is
for Source_Dirs use (".", "src");
for Object_Dir use "obj";
for Exec_Dir use "bin";
for Main use ("main.adb");
package Compiler is
for Default_Switches ("ada") use ("-mmcu=avr5");
end Compiler;
package Ide is
for Gnat use "avr-gnat";
for Gnatlist use "avr-gnatls";
for Debugger_Command use "avr-gdb";
end Ide;
package Builder is
for Executable_Suffix use ".elf";
for Default_Switches ("ada") use ("--RTS=rts-zfp");
end Builder;
package Linker is
for Default_Switches ("ada") use ("obj\crtm328p._o", "-nostdlib", "-lgcc", "-mavr5", "-Tdata=0x00800200", "-mmcu=avr5");
end Linker;
end Arduino;
and you can code a spec for your ATmega328P like
with Interfaces; use Interfaces;
with System;
package ATmega328P is
-- PORTB: Port B Data Register
PORTB : Unsigned_8;
for PORTB'Address use System'To_Address (16#25#);
-- DDRB: Port B Data Direction Register
DDRB : Unsigned_8;
for DDRB'Address use System'To_Address (16#24#);
-- PINB: Port B Input Pins
PINB : Unsigned_8;
for PINB'Address use System'To_Address (16#23#);
end ATmega328P;
to be imported by your main file or libraries.
Bear with me if this isn't the immediate answer; I have only used the AVR-Ada toolchain on Linux, so we may have to iterate towards a solution unless someone else spots the problem first.
The first thing to decipher is which version of the AVR-Ada tools you have:
your project file USED to need (using avr-ada 1.1)
with "C:\WinAVR-20100110\lib\gnat\avr.gpr";
Now with avr-ada 1.2.1 you need (instead)
with "C:\WinAVR-20100110\lib\gnat\avr_app.gpr";
for building applications, and <same path>/avr_lib.gpr for libraries.
I don't believe you ever need both! And they may conflict with each other.
I don't know the state of the Windows binary build, but if you need the latest version (recommended : it's a real improvement) you may need to build it from source.
Method 1 : were you running Make from a command line? If so, I would expect to see errors in all their gory details.
Method 2 : can't help you here, I don't know GPS well enough. However I can say that on Linux there are no "avr5" folders in [wherever]/avr/lib/gnat/avr_lib. (AVR5 is correct for the 328p)
Instead there IS a [wherever]/avr/lib/avr5 containing libc and other C-related objects - including the crtm328p.o that Rego names in his linker switches, and a [wherever]/lib/gcc/avr/4.7.2/avr5 folder containing libgcc.a. You probably need to find the former and point GPS at it...
Method 3 : This looks the easiest to fix. The "gnatmake" command needs an --RTS= option pointing at the correct RTS for the 328p. This should be --RTS=rts/avr5 assuming the RTS is correctly installed.
Alternatively a full path ought to work. Here, that would be
--RTS=/opt/avr_472_gnat/lib/gcc/avr/4.7.2/rts/avr5
on Windows you may have to poke around to find the correct path.
Using Method 1 this --RTS option is automatically generated by avr_app.gpr.
It appears that having a mix of 3 or 4 tool chains installed that provide one of aspects of WinAvr, AvrAda causes significant problems (these included WinAvr, Avr-Ada, Cygwin, AVR compiler by Adacore and MinWG).
Starting with a brand new Win7 or Win8 installation perform the following:
Install WinAVR-20100110 to C:\WinAVR-20100110
Copy the content of the Avr-Ada-1.2.0_bin to C:\avr-ada-1.2.0
Add C:\avr-ada-1.2.0\bin to the PATH
Compiling the content of each of the examples in C:\avr-ada-1.2.0\share\doc\avr-ada\apps identifies that some DLLs are missing: libiconv-2.dll, libgmp-10.dll, libmpc-2.dll, libmpfr-1.dll
These can be found in a MinGW installtion.
Create a virtual machine to install MinGW on, in order to ensure it did not mess with the main PC.
Copy the missing DLLs in C:\WinAVR-20100110\bin
The example in DS1820 will not compile due to crc_lib being missing.
In order to upload to the Arduino the makefiles must be modified for your local installation, board type etc.
Google Closure works GREAT without the Java Runtime Environment by using IKVM
In case that ever goes away, the simplified steps to convert it to an exe are:
Download and extract (but nothing to install) Closure Compiler and IKVM
Move compiler.jar to the IKVM bin folder
ikvmc -target:exe -fileversion:2012.09.17 .\compiler.jar (with the jar's release date). Note: I get a few warnings about ANT libraries.
Copy these dependencies from the ikvm bin directory to the closure directory:
IKVM.OpenJDK.Core.dll
IKVM.OpenJDK.Jdbc.dll
IKVM.OpenJDK.Misc.dll
IKVM.OpenJDK.SwingAWT.dll
IKVM.OpenJDK.Text.dll
IKVM.OpenJDK.Util.dll
XML.API.dll
IKVM.Runtime.dll
Then you can move the compiler.jar and new compiler.exe back to your closure directory. Fredrik recommends this powershell version of execution because of the ability to specify ascii encoding overriding unicode (half the bytes):
.\compiler.exe --js .\jquery-1.4.2.js --warning_level QUIET | out-file -encoding ascii .\jquery.min.js
==============================
However, I do not have the same luck with the Closure Templates's SoyToJsSrcCompiler.jar. I get warnings from ikvmc -target:exe -fileversion:2011.12.22 .\SoyToJsSrcCompiler.jar as with compiler.jar.
warning IKVMC0105: Unable to compile class "com.google.template.soy.jssrc.internal.GenerateSoyUtilsEscapingDirectiveCode"

Anyone know how to get this to work?
The exception can be an bug in IKVM. Which version do you use? Test the latest version.
warning IKVMC0100: Class "com.google.template.soy.jssrc.internal.GenerateSoyUtilsEscapingDirectiveCode" not found
Another problem can be that you have not compile all needed jar files for SoyToJsSrcCompiler.jar. In which jar file is this missing class file? Take a look in the wiki to see how you compile multiple jar files.
The next problem can be that there is the same package in different jar files. It there are only package visible for some mthods this will not work for .NET. You can test a sharedclassloader. See the wiki for details.
