[louie.nohay]

Hi,

I have a few concern to  ask to anyone who could help.. I got my projet using iaxclient working on windows, however, i am not able to run it on linux (ubuntu 10.10)..
Got an exception in loading library iaxclient.jar/ iaxclient.so.. For details on the exception trapped, please see logs below..

Code: [Select]

Exception in thread "thread applet-<package>.MyApplet.class-1" java.lang.UnsatisfiedLinkError: Unable to load library 'iaxclient': libiaxclient.so: cannot open shared object file: No such file or directory

Unable to load library 'iaxclient': libiaxclient.so: cannot open shared object file: No such file or directory
   at com.sun.jna.NativeLibrary.loadLibrary(NativeLibrary.java:145)

That shows path error, make sure the path of the .so file is correct.

got it babar.. i first thought it was the policy permission that causes the error.. but t'was not..
changed the original given code in IAXClient.java to this to work with my app..

Original code:

Code: [Select]

IAXClient INSTANCE = (IAXClient) Native.loadLibrary((Platform.isWindows() && FileExists.exists(System.getProperty("java.io.tmpdir") + "libiaxclient.dll"))
? System.getProperty("java.io.tmpdir") + "libiaxclient.dll"
: (Platform.isWindows() && FileExists.exists(System.getProperty("java.io.tmpdir") + "libiaxclient.dll"))
? System.getProperty("java.io.tmpdir") + "libiaxclient.so"
: "iaxclient"
, IAXClient.class);


Modified code:

Code: [Select]

IAXClient INSTANCE = (IAXClient) Native.loadLibrary(
                  (Platform.isWindows() && FileExists.exists(System.getProperty("java.io.tmpdir") + "lib/windows/libiaxclient.dll"))
                ? System.getProperty("java.io.tmpdir") + "lib/windows/libiaxclient.dll"               
                : (Platform.isLinux() && FileExists.exists(System.getProperty("java.io.tmpdir") + "lib/linux/libiaxclient.so"))
                ? System.getProperty("java.io.tmpdir") + "lib/linux/libiaxclient.so"
                : (Platform.isMac() && FileExists.exists(System.getProperty("java.io.tmpdir") + "lib/mac/libiaxclient.dylib"))
                ? System.getProperty("java.io.tmpdir") + "lib/mac/libiaxclient.dylib"
                :"iaxclient"
                , IAXClient.class);

Great 

[louie.nohay]

ouch.. i thought i already solved this.. same error still persist..
so i modify the code for IAXClient INSTANCE in to this:

Code: [Select]

IAXClient INSTANCE = (IAXClient) Native.loadLibrary(
                  (Platform.isWindows() && FileExists.exists(System.getProperty("java.io.tmpdir") + "libiaxclient.dll"))
                ? System.getProperty("java.io.tmpdir") + "libiaxclient.dll"               
                : (Platform.isLinux() && FileExists.exists(System.getProperty("java.io.tmpdir") + File.separator + "libiaxclient.so"))
                ? System.getProperty("java.io.tmpdir") + File.separator + "libiaxclient.so"
                : (Platform.isMac() && FileExists.exists(System.getProperty("java.io.tmpdir") + File.separator + "libiaxclient.dylib"))
                ? System.getProperty("java.io.tmpdir") +  File.separator + "libiaxclient.dylib"
                :"iaxclient"
                , IAXClient.class);

EXCEPTION CAUGHT was this:

Code: [Select]

java.lang.UnsatisfiedLinkError: Unable to load library 'iaxclient': libiaxclient.so: cannot open shared object file: No such file or directory

I couldn't understand why .so files were not written in java.io.tmp.dir (/tmp for linux) even though it was loaded in java cache.. (checked in java cache viewer)..

If you are testing applet then it must be in temporary internet files of Mozilla (or whatever browser you are using)
Still it shows path error.

I did a work around for loading libiaxclient files to java.io.tmpdir and successfully loaded it however i got this error.. is this an error on my client or is from the server configuration?

Does anyone here know where i can get the least updated source code for libiaxclient. The error below seems to look for a missing code that is calling speex codec.
