Hi all.
I'm having problems with using swig-generated wrappers with Clojure.
I'm running ubuntu-8.04-i386, gcc-4.2.4, swig-1.3.33, openjdk-1.6.0,
latest clojure release.
I've cut down a minimal reproducible example.
The swig file:
---file:swig_test.i---
%module swig_test
%{
int swig_test_whatever() {
return 3;
}
%}
int swig_test_whatever();
---cut---
Compile with:
---cut---
mkdir swig_test
swig -java -package swig_test -outdir swig_test swig_test.i
javac swig_test/*.java
export JAVA_HOME=/usr/lib/jvm/java-6-openjdk
export JNI_CFLAGS="-I${JAVA_HOME}/include -I${JAVA_HOME}/include/
linux"
gcc -shared ${JNI_CFLAGS} swig_test_wrap.c -o libswig_test.so
---cut---
The swig-generated java itfc file is:
---file:swig_test/swig_test.java---
package swig_test;
public class swig_test {
public static int swig_test_whatever() {
return swig_testJNI.swig_test_whatever();
}
}
---cut---
The clojure code:
---cut---
(import '(swig_test swig_test))
(System/load
(.concat (System/getProperty "user.dir") "/libswig_test.so"))
(swig_test/swig_test_whatever)
---cut---
I get:
java.lang.UnsatisfiedLinkError:
swig_test.swig_testJNI.swig_test_whatever()I (NO_SOURCE_FILE:0)
I can use "manually written" JNI wrappers with clojure and, vice-
versa, swig-generated wrappers with plain java code. What I'm missing
here? Anybody can help?
Bests,
Antonio, Fabio Di Narzo.
