It looks like the include path you specified (-I /System/Library/Frameworks/JavaVM.framework/Versions/1.4.2/Headers) does not exist, try and locate the actual location on your filesystem and use it instead...
eg. on my system they are located in /Library/Java/Home/include

Subject: Compilation Errors...... Classpath??
Hi Guys,
Im trying to follow a new JNI tutorial (see here:
http://www.mindspring.com/~david.dagon/jni/Native.txt ) and am getting a
selection of compilation errors when trying to build my library at step 5...
**************************************************************
sam-aspins-mac-mini:~/Jan06/com2 samaspin$ cc -bundle -o libHello.jnilib
-framework JavaVM \
-I/System/Library/Frameworks/JavaVM.framework/Versions/1.4.2/Headers \ .
Hello.c
powerpc-apple-darwin8-gcc-4.0.0:
-I/System/Library/Frameworks/JavaVM.framework/Versions/1.4.2/Headers: No
such file or directory
powerpc-apple-darwin8-gcc-4.0.0: .: No such file or directory
Hello.c:4:17: error: jni.h: No such file or directory
In file included from Hello.c:6:
HelloWorld.h:15: error: syntax error before 'void'
HelloWorld.h:16: error: parse error before '*' token
HelloWorld.h:16: warning: data definition has no type or storage class
Hello.c:7: error: syntax error before 'void'
Hello.c:8: error: parse error before '*' token
Hello.c: In function 'Java_HelloWorld_sayHello':
Hello.c:10: error: 'env' undeclared (first use in this function)
Hello.c:10: error: (Each undeclared identifier is reported only once
Hello.c:10: error: for each function it appears in.)
Hello.c:10: error: 'strMessage' undeclared (first use in this function)
*************************************************************************
I've also tried it using the exact path specified in the example but after
doing some googling have found that this actually points to a 'shortcut'
file and anot the actual jni.h header.
It looks to me like the first problem is that it's not locating the Headers
and subsequently the jni.h header file, am i correct?
I'm hoping that if i get this part sorted then the other errors might
dissapear as well!
I have done some googling and was wondering if perhaps this has something to
do with classpaths?? how do i check/set-up the classpath??
any help will be greatly received.
thanks
Sam Aspin
