I'm trying to build the Java port of cld on Ubuntu 12.04 64-bit, using OpenJDK 6. The shared object file built by Maven contains the JNI bindings, but the CompactLangDet::DetectLanguage symbol is undefined. (Bit of a C++ newbie) I can't tell if the intent is for the Maven-built wrapper to be used alongside the make-built libcld, or whether Maven is supposed to be generating an "all-in-one" library.

I am encountering a symbol lookup error when running CompactLanguageDetector's main method from the command line, with the Maven-generated shared object being loaded as libcld, like so:

ln -s libcld/0.0.1-SNAPSHOT/libcld-0.0.1-SNAPSHOT.so libcld/0.0.1-SNAPSHOT/libcld.so 
java -Djava.library.path=./libcld/0.0.1-SNAPSHOT/ -cp cld/1.0-SNAPSHOT/cld-1.0-SNAPSHOT.jar com.mzsanford.cld.CompactLanguageDetector "octocat"
java: symbol lookup error: ~/.m2/repository/com/mzsanford/cld/libcld/0.0.1-SNAPSHOT/libcld-0.0.1-SNAPSHOT.so: undefined symbol: _ZN14CompactLangDet14DetectLanguageEPKNS_15DetectionTablesEPKcibbbbS4_i8LanguagePS5_PiPdS7_Pb

I'm setting the JAVA_HOME and LD_LIBRARY_PATH variables via an export statement:

export LD_LIBRARY_PATH="/usr/local/lib/cld:/usr/lib" && export JAVA_JOME="/usr/lib/jvm/java-6-openjdk-amd64" && mvn install

Examining the shared object produced by Maven (libcld-0.0.1-SNAPSHOT.so) using nm -gC shows that the CompactLangDet:DetectLanguage symbol is undefined.

U CompactLangDet::DetectLanguage(CompactLangDet::DetectionTables const*, char const*, int, bool, bool, bool, bool, char const*, int, Language, Language*, int*, double*, int*, bool*)

I've also tried writing code that loads the Maven-generated wrapper then libcldfrom /usr/local/lib/cld/ and vice-versa, but it hasn't helped.

Could someone please tell me:
a) is the Maven-generated artifact supposed to be self-contained? (i.e. provides libcld and the JNI wrappers in the same file)
and
b) am I building incorrectly?

Thanks!

Add a .gitignore for the autotools output that does not need to be in git.

The original Python port needs to be moved into the ports directory and the build updated to link against the shared libcld. It probably needs documentation and test updates as well.

followed install instructions but no luck 🤷

Incorrect information after the Google Code migration. Needs new build and install information as well as an overview.

The Java API only supports simple results. A new API is needed for detailed results. Also needed are javadocs and a sane build/install system. This is difficult for JNI but should be possible.

I was able to build successfully with
source ./build.sh
I verified by running
./example and getting this output

However when I try to install the python bindings with:

I am using Python 2.7.1 and OS X 10.7.3

I compared several Language-Detection packages and came to the conclusion that yours might be one of the best for the node community. The only other lib we can rely on is FGRibreau's node-language-detect, which has a similar level of awesomeness and -ok- is in fact updated more often. But I'm pretty sure he has a time machine or something, to get his stuff done. Not fair ;o)

I like yours a little bit more because it's based on Chromium (which is important for me), is >100x faster and is surely more memory efficient than node-language-detect.

I already tried to write my own binding.gyp and to compile it via node-gyp under node v.0.10.x, but without luck.

So, if you can afford some minutes, you would make me really happy ^-^

I guess the required steps are:

• migrate from wscript to binding.gyp (see node-gyp)
• migrate from libeio to libuv (i found this old howto, dunno if it helps...)

Keep up the good work!

I'm trying to build the Java port of cld on centos 64-bit , using Virtualbox.
I followed your 'README.md' and Setting was finished.
i made new java project and i move 'cld/ports/java/java/src' to new '/src'.
but it doesn't work.
error is

Exception in thread "main" java.lang.UnsatisfiedLinkError: com.mzsanford.cld.CompactLanguageDetector.detectLanguageDetails(Ljava/lang/String;ZZZZLjava/lang/String;)Lcom/mzsanford/cld/LanguageDetectionResult; at com.mzsanford.cld.CompactLanguageDetector.detectLanguageDetails(Native Method) at com.mzsanford.cld.CompactLanguageDetector.detect(CompactLanguageDetector.java:23) at com.mzsanford.cld.CompactLanguageDetector.main(CompactLanguageDetector.java:41)

what should i do?

The Ruby port needs to be refactored into a usable gem. This includes more robust build options (check for libcld), rdoc, and a refactored API for better detailed response data.

Either port from Chromium or write anew but it needs something. Some examples as well as API documentation would be good.

Hi,

After installing the library with Homebrew on Mac OS X Mavericks I am getting the following error:

import cld
Traceback (most recent call last):
File "", line 1, in
ImportError: dlopen(/Users/toddysm/anaconda/lib/python2.7/site-packages/cld.so, 2): Symbol not found: __Z12LanguageCode8Language
Referenced from: /Users/toddysm/anaconda/lib/python2.7/site-packages/cld.so
Expected in: dynamic lookup

Any ideas?

The Node port has the most complete API but needs to be documented better and packaged for npm.

Hey,
I've installed and built the C++ library, and when I run make check, the test successfully passes.

But when I go to ports/java and run mvn test, the test fails (Compact Language Detector - native unix) and it seems like it's because it can't locate the relevant files.
I guess there could be a simple fix, but I'm not really familiar with C++ and ports :(
If anybody can help, that'd be great :)

Hello together,

cld works just fine on 10.10 with python3.3
But, when I try to look at the languages with print (cld.LANGUAGES) I get this error:

/Library/Frameworks/Python.framework/Versions/3.3/Resources/Python.app/Contents/MacOS/Python: can't open file 'cldLANGUAGES': [Errno 2] No such file or directory

cld.ENCONDINGS and cld.DETECTED_LANGUAGES does not work neither.

Can anyone just do that real quick for me and copy & paste the result for me.
That would be very nice!

Thanks!

Thanks for the nice repackaging. It still needs some work on Windows though. To compile:

1. open a cmd window
2. run vcvarsall.bat (FIXME: why is this commented out in build.win.bat?)
3. run build.win.bat
4. FIXME: copy libcld.lib to ports/python/cld.lib
5. FIXME (biggest one): setup.py fails on Windows

The hackish solution to (5) is to make pkgconfig return (on Windows only) the dict {'define_macros': [('WIN32',None)], 'libraries': packages}
Why the hack is necessary: On windows, pkg-config is not available by default. If you get it, it depends on a dll. If you get that one as well, it doesn't find the cld.pc file. If you copy it over, it returns the nonsensical (for MSVC) value "-I/usr/local/include/cld -L/usr/local/lib/cld -lcld". It also fails to define WIN32, without which the whole thing does not compile.

Do you prefer getting a pull request or making the changes yourself? Thanks.

Line 10 of cld_utf8statetable states

include "util/utf8/utf8statetable.h"

That file does not exist in the project. It does exist in the CLD2 project. This is why I think people are having linking problems. It looks like some of the new source file slipped into your project.

As said in the title. Some compilers throw an error on implicit casting; there must be a better way to do this.

What generates this code?

I want to install the chrome language detection (cld) https://github.com/mzsanford/cld for Python.
I am working on OS X 10.10 with Python 3.3, installed through a download of the .dmg from the Pythonwebsite.

What did I do so far?

1. Downloaded and updated xCode to the most recent version
2. Command Line Tools for xCode installed with that line $ xcode-select –install
3. Downloaded the GNU, C and C++ Compilerhere http://hpc.sourceforge.net and installed via $ sudo tar xvf gcc-4.9-bin.tar -C /
4. Install the libcld C++ library following the instructions on https://github.com/mzsanford/cld (I installed it from source, not with homebrew)!
5. Installed the pkg-config package $ git clone git://anongit.freedesktop.org/pkg-config

Then I followed the steps described to install the Pythonbindings:

$ git clone http://github.com/mzsanford/cld.git

$ cd cld/ports/python

$ make install # This will prompt for your password

Which gave me this error message:

python -u setup.py build
Traceback (most recent call last):
File "setup.py", line 17, in <module>
**pkgconfig('cld'))
TypeError: __init__() keywords must be strings
make: *** [build] Error 1`

I also downloaded the source and tried to install it with python3.3 setup.py which gives me this

 pkg-config has not been found but this setup script relies on it.

Well, I installed id, but it seems that it does not find it.
Might that be a problem that it installed it to the Python the system is using (which would 2.7) while I use Python3.3? Or other suggestions?

CLD is unable to detect Japanese language for the following Text

2014年初めての全体MTGにて、「Q＆CSってそもそも何のための組織だっけ？」というタイトルのもと、Q＆CSが組織としてやろうとしていること、やるべきことを話されました。 '

Steps to reproduce -->

1. import cld

2. code = cld.detect(smart_str(text), pickSummaryLanguage=True, removeWeakMatches=False)

3. Output
   code = ('ENGLISH', 'en', True, 11, [('ENGLISH', 'en', 100, 0.8103727714748784)])

The text contains Japanese text also. but it is not been detected

It seems that the only real method I can call on the ruby port of CLD at the moment is to return a single ENUM int (0 for English etc.)

When trying to initialise the detector I just get the following:

uninitialized constant CLD::Detector (NameError)

To be honest, I don't use *.detectSync() at the moment, because i don't understand the parameter skipWeakMatches in detail. But it's elegant (requires us like 1 line of code) and darn fast (50% faster than *.detect() in some cases). So it might be cool to invest a little more devtime into this function.

During my tests i noted that *.detectSync() behaves completely different than *.detect(), i.e. it fails a lot more often. Looks like this isn't a problem with specialchars or sth., but most likely with the string length.

The following table compares the output of

• languagedetect.detect() = "V1"
• cld.detectSync() = "V2"
• cld.detect() = "V3"

Chars | V1 | V2 | V3

Aaaand some hacky code:

var ASYNC = require('async');
var LANGDETECT = new (require('languagedetect'))('iso2');
var CLD = new (require('cld/cld.node').LanguageDetector)();


//str_repeat('Foo',3) => 'FooFooFoo'
function str_repeat(a,b){ for(var c="";;)if(b&1&&(c+=a),b>>=1)a+=a;else break;return c }


//LANGDETECT.detect()
function detect_v1(str,cb)
{ 
  var res = LANGDETECT.detect(str,1); 

  cb(
    null, 
    res.length && res[0][0] ? res[0][0] : false
  ); 
}

//CLD.detectSync()
function detect_v2(str,cb)
{ 
  var res = CLD.detectSync(str);

  cb(
    null, 
    res && res !== 'un' ? res : false
  ); 
}

//CLD.detect()
function detect_v3(str,cb)
{ 
  CLD.detect(str,function(res)
  { 
    cb(
      null, 
      res && res.languageCode && res.languageCode !== 'un' ? res.languageCode : false
    ); 
  }); 
}

console.log('#Chars  | V1  | V2  | V3 ');   
console.log('------- | --- | --- | ---');   
for(var i=1, i_max=100, str; i <= i_max; ++i)
{
  //str = str_repeat('Hans und Gretel gingen in den Wald, dort war es finster und auch so bitterkalt. ',i);
    str = str_repeat('Alle meine Entchen schwimmen auf dem See, den Kopf dann in das Wasser und blub. ',i);

  (function(str)
  {
    ASYNC.parallel(
    {
      v1: function(cb){ detect_v1(str,cb); },
      v2: function(cb){ detect_v2(str,cb); },
      v3: function(cb){ detect_v3(str,cb); }
    },
    function(err,res)
    {
      console.log(str.length+' | '+res.v1+' | '+res.v2+' | '+res.v3);
    });  
  })(str);
}

The code was received second hand and the original license needs to be researched. Once found it needs to be added in the LICENSE file. Be sure to update the Homebrew package (https://github.com/mzsanford/homebrew) once that's done.

My C/C++ is really rusty and in many cases I'm not used to the embedding APIs of the various languages. Each binding in the ports directory needs to be tested for memory leaks and other issues.

With OS X v10.8.3, following the instructions here: http://mzsanford.com/blog/introducing-libcld

With brew install https://raw.github.com/mzsanford/homebrew/libcld/Library/Formula/libcld.rb I get:

READ THIS: https://github.com/mxcl/homebrew/wiki/troubleshooting

Or when following the manual instructions, the same error at the ./configure step.

configure: error: cannot find install-sh or install.sh in "." "./.." "./../.."

Any idea what's wrong?
