jpgraph: Internal error: Chosen locale file for error messag

[kond]

Hi all,

I can not make jpgraph working with mantis.
Jpgraph works ok when called from my own php scripts.
It also works ok when called from jpgraph examples scripts.
But i can only see "red cross" in mantis.

When i called the graph itself
(like this: https://servername/summary_graph_byreso ... &token=184)
I got the following error:
Internal error: Chosen locale file for error messages does not exist.

After some investigations i still don't know how tomake it work with mantis.

I use mantis 1.0.8
php 5.2.1
jpgraph 2.1.4
apache 2.0
freebsd 6.2

here are define statements from jpg-config.inc.php:
DEFINE("TTF_DIR","/usr/X11R6/lib/X11/fonts/winfonts/");
DEFINE("CSIMCACHE_DIR","csimcache/");
DEFINE("CSIMCACHE_HTTP_DIR","csimcache/");
DEFINE('CHINESE_TTF_FONT','bkai00mp.ttf');
DEFINE("LANGUAGE_GREEK",false);
DEFINE("GREEK_FROM_WINDOWS",false);
DEFINE("LANGUAGE_CYRILLIC",true);
DEFINE("CYRILLIC_FROM_WINDOWS",true);
DEFINE('LANGUAGE_CHARSET','windows-1251');
DEFINE('MINCHO_TTF_FONT','ipam.ttf');
DEFINE('PMINCHO_TTF_FONT','ipamp.ttf');
DEFINE('GOTHIC_TTF_FONT','ipag.ttf');
DEFINE('PGOTHIC_TTF_FONT','ipagp.ttf');
DEFINE('ASSUME_EUCJP_ENCODING',false);
DEFINE('DEFAULT_ERR_LOCALE','en');
DEFINE("DEFAULT_GFORMAT","auto");
DEFINE("USE_CACHE",false);
DEFINE("READ_CACHE",false);
DEFINE("USE_IMAGE_ERROR_HANDLER",true);
DEFINE("CATCH_PHPERRMSG",true);
DEFINE("INSTALL_PHP_ERR_HANDLER",true);
DEFINE("USE_APPROX_COLORS",true);
DEFINE("ERR_DEPRECATED",true);
DEFINE("BRAND_TIMING",false);
DEFINE("BRAND_TIME_FORMAT","(%01.3fs)");
DEFINE("CACHE_FILE_GROUP","www");
DEFINE("CACHE_FILE_MOD",0664);
DEFINE("USE_BRESENHAM",false);
DEFINE("_CSIM_SPECIALFILE","_csim_special_");
DEFINE("_CSIM_DISPLAY","_jpg_csimd");
DEFINE("_IMG_HANDLER","__handle");

and here are jpgraph settings from mantis config_inc.php
$g_use_jpgraph = ON;
$g_jpgraph_path = '/usr/local/share/jpgraph/';
$g_graph_font = 'arial';

Please advise where to look for the cause of the problem?

Thanks in advance,
Nikolay.

What language are you using? Try to test it with English as the current language.

I'm using russian language.
But i tried with english (as a language for the account) - result is the same.
And when i'm calling jpgraph from my own scripts - rusisan letters are shown ok.

Thanks and regards,
Nikolay.

I solved the problem. Tha cause was as following:

There is an error handler (jpgraph_errhandler.inc.php) file in jpgraph direcory, which contains the following code:
// If the chosen locale doesn't exist try english
if( !file_exists(dirname(__FILE__).'/'.$file) ) {
$__jpg_err_locale = 'en';
}

$file = 'lang/'.$__jpg_err_locale.'.inc.php';
if( !file_exists(dirname(__FILE__).'/'.$file) ) {
die('Internal error: Chosen locale file for error messages does not exist.');
}

In my case jpgraph package was installed using freebsd "ports". I dont understatnd why it happened but there was no "lang" directory in my jpgraph installation.
I downloaded jpgraph source, and extracted "lang" directory into /usr/local/share/jpgraph, where jpgraph is installed.
After this there were no more "red cross" instead of graphs. Now i got jpgraph error message claiming that constant FF_BOOK is not defined.
I commented out corresponding line in graph_api.php and now graphs in mantis are ok.
My own scripts, calling jpgraph, were ok because there were no errors in those scripts.

So there were two problems:
1. undefined constant FF_BOOK in mantis code (graph_api.php)
2. abcense of lang/en.inc.php file in jpgraph installation.

Hope this information may be useful for other mantis/jpgraph users.

Thanks and regards,
Nikolay.

Hi all, I don't know what is Mantis, I was trying to use jpgraph 2 and was not working, I was using php5.0 then i installed php 5.2 and i still have a red cross instead of the graph. I did the following steps for it to work:
First: there is a bug in the jpgraph.php file. on approximately line 77, there is a definition for the variable TTF_DIR without checking if the variable was already defined. Therefore, you have to modify the following code as follows:

Initial code:

Code: Select all

if (!defined('MBTTF_DIR')) {
    if (strstr( PHP_OS, 'WIN') ) {
	$sroot = getenv('SystemRoot');
        if( empty($sroot) ) {
	    $t = new ErrMsgText();
	    $msg = $t->Get(12,$file,$lineno);
	    die($msg);
        }
	else {
	  define('TTF_DIR', $sroot.'/fonts/');
        }
    } else {
	define('MBTTF_DIR','/usr/share/fonts/ja/TrueType/');
    }
}

Modified code:

Code: Select all

if (!defined('MBTTF_DIR')) {
    if (strstr( PHP_OS, 'WIN') ) {
	$sroot = getenv('SystemRoot');
        if( empty($sroot) ) {
	    $t = new ErrMsgText();
	    $msg = $t->Get(12,$file,$lineno);
	    die($msg);
        }
	else {
		if (!defined('TTF_DIR')){
	  	define('TTF_DIR', $sroot.'/fonts/');}
        }
    } else {
	define('MBTTF_DIR','/usr/share/fonts/ja/TrueType/');
    }
}

If you changed the code, and you're still getting the red cross, remove all the line returns from the end of all the files in the src folder;
