My programm is an interface between Java and Mathematica I have created
a shared library (*.so).

After executing the Java application the following error ocours:

eclab17.zahnb[29] new/classes > java JMathLinkTest ld.so.1:
/opt/pub/java/bin/../bin/sparc/green_threads/java: fatal: relocation
error: symbol not found: MLClearError__FP5MLink: referenced in
./libMathLink4Java.so (libMathLink4Java.so)
java.lang.UnsatisfiedLinkError: no MathLink4Java in shared library path
        at java.lang.Runtime.loadLibrary(Runtime.java)
        at java.lang.System.loadLibrary(System.java)
        at packages.mathematica.JMathLink.<init>(JMathLink.java:68)
        at JMathLinkTest.main(JMathLinkTest.java:28)

This is my makefile:

PROJECT_HOME = /home/students/m97b/zahnb/java/packages/mathematica/new

CC = gcc

JDK_HOME = /opt/pub/java
JAVAC = ${JDK_HOME}/bin/javac
JAVAH = ${JDK_HOME}/bin/javah

JDK_CLASSPATH = ${JDK_HOME}/lib/classes.zip PACKAGE_CLASSPATH =
${PROJECT_HOME}/classes


# Create Shared Lib C File
libMathLink4Java.so: packages_mathematica_JMathLink.o
	${CC} -G packages_mathematica_JMathLink.o -lML -L./ -o $@ -lm -lsocket
-lnsl

# Compile C File
packages_mathematica_JMathLink.o: packages_mathematica_JMathLink.h
packages_mathematica_JMathLink.C
	${CC} -c -I${JDK_HOME}/include -I${JDK_HOME}/include/solaris
packages_mathematica_JMathLink.C


# Generate C Header Files
#packages_mathematica_JMathLink.h:
classes/packages/mathematica/JMathLink.class #	@echo "GENERATING C
HEADER FROM JAVA CLASS" #	${JAVAH} -jni -classpath
${PACKAGE_CLASSPATH}:${JDK_CLASSPATH} $@
