Try opening ClangLibrary.java and modify JNA_LIBRARY_NAME from "Clang" to "clang"; does that help?

4ntoine commented 11 years ago

No: java.lang.UnsatisfiedLinkError: Unable to load library 'clang'

amishne commented 11 years ago

You can try setting jna.library.path instead of java.library.path; though the latter should also work as far as I know. Another option (what I do) is to set the path from within the code: move the initialization from the static fields of ClangLibrary to your own code, and make sure to call NativeLibrary.addSearchPath before NativeLibrary.getInstance. At least it works for me (with "clang" and not "Clang") - on Linux, though, not Windows, so the problem may be something else entirely.

I'll try later on mac

4ntoine commented 11 years ago

config.jnaerator file contains absolute paths: -I/usr/lib/gcc/x86_64-linux-gnu/4.6/include/ -I/usr/include/c++/4.6/x86_64-linux-gnu/ -I/usr/include/x86_64-linux-gnu/ -I/usr/include/linux/ -Isrc/main/c/clang-c/

Should they be changed? "mvn clean install" finished without any errors

4ntoine commented 11 years ago

for mac i have to add

<dependency>
    <groupId>com.nativelibs4java</groupId>
    <artifactId>jnaerator-runtime</artifactId>
    <version>0.11</version>
        <scope>compile</scope>
</dependency>

i was able to compile test, but it returns unit = null. (cpp file exists and is valid. i believe libclang.so was found as no error in the log as for windows). so i heed simple example on how to make it working.

package clang;

import junit.framework.TestCase;

/**
 * Extract meta-info test
 */
public class ExtractTest extends TestCase {

    public void testExtract1() {
        ClangLibrary lib = ClangLibrary.INSTANCE;

        ClangLibrary.CXTranslationUnit unit = lib.clang_parseTranslationUnit(null, "/Users/me/dev/clang/source.cpp", null, 0, null, 0, 0);
    }
}

4ntoine commented 11 years ago

Probably i was trying to use wrong function just to parse the file. clang_indexSourceFile seems to be what i need but it just returns result = 1 in the test

public void testExtract1() {
        ClangLibrary lib = ClangLibrary.INSTANCE;

        callbacks.startedTranslationUnit = new IndexerCallbacks.startedTranslationUnit_callback() {
            @Override
            public Pointer apply(Pointer client_data, Pointer reserved) {
                return null; // not invoked
            }
        };

        int result = lib.clang_indexSourceFile(null, null, callbacks, 1, 0, "/Users/me/dev/clang/source.cpp", null, 0,  null, 0, null, 0);
    }
