[Festival-libestools]Can someone show me the magic to compile the libestools?
Hi, dear developers, I'm a voice application developer. Recently I use the Festival in our project. First, I downloaded the festival and speech tools source codes and compile them in my Ubuntu8.04. Then I wrote a test C++ application which can run well to invoke the libFestival as part of the application. Then I use JNI to wrap them to a Java interface. Unfortunately the same native codes implementation crashed JVM every time. Thanks to the open source codes, I can track it's because of the libestools crashed the JVM--- but the native application runs well. When I finally plan to give up and try to use the festival client, I installed the festival and the libest from Ubuntu repository. Actually, they have the same newest version. When I recompile the native codes after removing the -L option, the magic happened-- it works, no codes change at all! I really got confused I even use the same configuration in speech_tools-- enable SHARED, why my homebrewed library will always crash the JVM? BTW: the JVM indicates the libestools use invalid memory address. I really want get the answer from the maintainer of the Ubuntu Festival-libestools. Can you give me some clues about how you set the compilation options? Since Ubuntu is only my work station, our real production platform is RHEL and CentOS(sadly, our Ops think they are enterprise level Linux, although I don't agree it that much...), I want to use the same compilation options for our production boxes so my application can run in these boxes well. Thanks a lot! -- -- Yueyu Lin -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
How about to patch synapatic to make it actively download packages using multiple threads?
As you noticed, sometimes, synaptic downloads packages slowly. I noticed that apt-get in fact can use multiple threads to download sometimes. But synaptic seems seldom to do this. I wanna know why? In fact, it will not be difficult to modify codes to support active multiple threads downloading. But it doesn't appear. I guess developers think it's impolite to fork a lot of threads to download things from server. The server may only serve for a few *rude* people. If it's true, I will stop any attempts to do so. If it's not,I can have a try to do this. -- -- Yueyu Lin -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
Re: How about to patch synapatic to make it actively download packages using multiple threads?
The problem to download from multiple server is that multiple servers may not be synchronized at the same time. Data synchronization is a serious problem. But I guess this should be better if we can make sure that multiple servers have the same package files.

How about to patch synapatic to make it actively download packages using multiple threads?
I'm going to do so. The first assumption is that a set of repository servers have synchronized data correctly. But that will be ok after the md5sum verification.

Help!Can anyone be so nice to share the Purevoice Linux SDK?
Hi, all If you're the voice codec developers, you may know Qualcomm closed the Purevoice SDK downloads since Dec 31,2007. As I don't save a copy of that and cannot see any signs Qualcomm will re-open it soon, can anyone who has the SDK to share with me? I don't think it will violate any laws cause Qualcomm used to open downloads and even Qualcomm's brew SDK is free. Thanks in advance. Any help will be highly appreciated! -- -- Yueyu Lin -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
