Re: problem with jni lib

I used g++ instead of gcc now and it seems the error is fixed. thanks for your help. l learned a lot about library files now. Cheers, Kason Joi Ellis wrote: > On Tue, 31 Oct 2000, kason wong wrote: > > > Hi, > > > > I guess I know what's the really problem is. > > > > I think I should make my p

Re: problem with jni lib

Hi, I guess I know what's the really problem is. I think I should make my problem more clear. I used to use libutil.a libpthread.a libcops.a to make ReqMsg.cxx executable. now I want to use COPS.cxx and .h files (JNI layers) to link a java program to call ReqMsg. so I modified a little of yo

Hi, I get another problem when i ran the java program with jni calling c++ program. Is it the bug of green thread? method unknown (eip = 400dc51b) SIGSEGV 11* segmentation violation si_signo [11]: SIGSEGV 11* segmentation violation si_errno [0]: Success si_code [0]: SI_USER [pi

Re: problem with jni lib

I guess I finally understand. but i still have problem in compiling one lib: libutil.so which used the libpthread.a lib in c. I try to convert libpthread.a to .so, it seems strange but when i load it: ld -shared -o libpthread.so --whole-archive /local/usr/lib/libpthread.a ldd -r libpthread.so

hi, I'm not sure this is the mail-list i should send my question. please let me know if I've got the right place. my problem is in the compiling a function in c++ to a .so lib file. the case is I use a couple static .a lib in that c++ program and when i compile it to a .so lib. it doesn't inclu

Problem with JNI

Hi, I've racked more brains than I've got trying to figure this out. If someone can give me a hint as to how I can proceed with solving this problem, I would be obliged. I'm invoking the JVM using dlopen to open the 1.2.2 libjvm.so and am doing a dlsym of the JNI init args and JNI Creat

Re: Problem with JNI

You will probably have to extern "C" the code in your C++ library. JNI uses C calling conventions. Mark Pierre Héroux <[EMAIL PROTECTED]> on 01/05/2000 03:47:12 AM Please respond to [EMAIL PROTECTED] To: [EMAIL PROTECTED] cc:(bcc: Mark Delafranier/SYBASE) Subject:

I hava a problem with JNI. I use RedHat 6.1 and jdk1.2.2. The following code doesn't work public class Native { static { System.loadLibrary("Native"); System.out.println("The Library is loaded..."); } public Native() {} public native void Hello();
