libjsmile.so compilation error on OS X

i686-apple-darwin9-g++-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5490)
[on MacOSX 10.5.8 (Intel)]

I take it only the compilation line matters?
g++ -O3 -DNDEBUG -feliminate-unused-debug-symbols -dynamiclib -o libjsmile.jnilib ../*.cpp -I$JINC -I../cppsmile -L../cppsmile -lsmilearn -lsmile

One of the users posting earlier in this thread reported a success with gcc build 5484. There's a chance that compiler shipped with 10.5.8 is no longer compatible with gcc 4.0.0 included in Darwin we're using to build OSX binaries.

I was trying to find out how to install JDK in Darwin so I could build jSMILE for OSX myself, but without success. If you know how to do that, let me know.

To compile the Java I installed JDK 6 Update 16 with Java EE. I exported this JINC variable in the build file as mentioned somewhere in this thread. Below the complete build file. I just run in from the terminal.

export JINC=/System/Library/Frameworks/JavaVM.framework/Headers/
echo $JINC

if ! [ -a "cppsmile/libsmile.a" ]
then
echo libsmile.a was not found in smile directory
exit -1
fi

if ! [ -a "java/smile/Network.java" ]
then
echo Network.java was not found in jsmile/java directory
exit -2
fi

if ! [ -a "$JINC/jni.h" ]
then
echo jni.h was not found
echo JDK include directory is configured to: $JINC
echo make sure it is correctly set for your environment
echo by setting JINC variable in this build script
exit -3
fi

echo compiling java source
cd java
rm -f *.jar *.so *.class
javac smile/*.java smile/learning/*.java
jar cf smile.jar -C . smile
javac -cp smile.jar testApp.java

The problem is that I can't install JDK at all, because we don't have Apple hardware. Instead, we run virtualized Darwin 8.0. The JDK downloads at java.sun.com don't include the OSX binaries; the only way to get them is through Apple Software Update feature, which is not present in Darwin.

Is there a way to bypass the Java problem? I could send the compiled versions of the Java code?

I might upgrade to MacOSX 10.6 which has a new XCode which might resolve the compilation error. However, I'm also searching for a C guru that could help out. It seems that the missing type is externally defined, probably in the main code?

The Java side is not a problem at all - it's the same across all platforms. The compilation error is in native C++ code. It may be caused by a mismatch between compiler versions on Darwin and OSX.

jSMILE binaries for OSX are now available.

Excellent! Our code now seems to work cross-platform. Many thanks for the effort. Much appreciated!
