Hello, I'd like create a unix shared library that will make some call to a WIN32 DLL using wine. Is this possible, and if it is so, where may I find some documentation pointers on how to achieve this ? Tnx, Vittorio

It is easy enough to make a winelib executable or dll, well I guess you could use system() or popen() or something from a library...> Is this possible, and if it is so, where may I find some documentation > pointers on how to achieve this ?man winemaker> > Tnx, > Vittorio > >Lawson -- ---oops--- ________________________________________________________________ Sign Up for Juno Platinum Internet Access Today Only $9.95 per month!

Hi, because I want to do the same (calling functions in a windows native dll for which I don't have the sources via java native interface on linux) I've made some tests. I've started writing a jni dll for windows to use the windows native dll and it works fine. "Converted" that library into a linux shared library using winemaker and modified the Makefile.in to change the name of the library from jv4face.dll.so to libjv4face.so. The jni library libx.so can be loaded by the java vm and native functions can be called. But there are a few problems which I hadn't solved until now: 1.) The DllMain entry point of the library is not called. 2.) If I call the windows function LoadLibrary to load the native dll I want to use, I get the following exception trace:>An unexpected exception has been detected in native code outside the VM. >Unexpected Signal : 11 occurred at PC=0x4C3B6496 >Function=Java_de_spocks_vgap_v4_V4FaceLibrary_internalVersionNumber+0x46 >Library=/home/schlegel/java/spocks/jni/libjv4face.so > >Current Java thread: > at de.spocks.vgap.v4.V4FaceLibrary.internalVersionNumber(Native Method) > at de.spocks.vgap.v4.V4FaceLibrary.getVersionNumber(V4FaceLibrary.java:55) > at TestV4Face.main(TestV4Face.java:12) > >Dynamic libraries:[snip (removed the java libs to shorten the message)]>4c3b5000-4c3c9000 r-xp 00000000 21:07 474062/home/schlegel/java/spocks/jni/libjv4face.so>4c3c9000-4c3ca000 rw-p 00013000 21:07 474062/home/schlegel/java/spocks/jni/libjv4face.so>4c3dd000-4c3e2000 r-xp 00000000 21:07 2399074/usr/local/lib/libwine.so.1>4c3e2000-4c3e3000 rw-p 00004000 21:07 2399074/usr/local/lib/libwine.so.1>4c3f5000-4c4d5000 r-xp 00000000 21:07 2399073/usr/local/lib/libwine_unicode.so.1>4c4d5000-4c4d7000 rw-p 000df000 21:07 2399073/usr/local/lib/libwine_unicode.so.1>Local Time = Sun Apr 13 14:07:38 2003 >Elapsed Time = 0 ># ># The exception above was detected in native code outside the VM ># ># Java VM: Java HotSpot(TM) Client VM (1.4.1_01-b01 mixed mode) >#What is "Signal 11"? Maybe wine initialition is not correct but there are loaded wine libraries. Any ideas why the call to LoadLibrary results in that exception and how to solve that?
