Libusb Java / Discussion / Help: problem building under macosx

mike - 2007-03-13

Hi,

I'm interesting in building libusbJava under Mac OSX. However, I'm having some problems, and would appreciate any help on this matter.

-- Mike

I have modified the build.xml file and the project.properties file.

Below is the project.properties file:

------------------------------------------------------------
############################
# common build properties #
############################
# folders
build.dir.src=src
build.dir.bin=bin

# filenames
build.lib.libusb=libusb.a
build.lib.libusbpp=libusbpp.a
build.shlib.srcname=LibusbJava.cpp
build.shlib.win.shlibname=LibusbJava.dll
build.shlib.linux.shlibname=libusbJava.so
build.shlib.mac.shlibname=libusbJava.so
build.test.srcname=LibusbTest
build.test.execname=LibusbTest

#####################################

build.mac.includes=/usr/local/lib
build.mac.jni=/System/Library/Frameworks/JavaVM.framework/Versions/Current/Headers
------------------------------------------------------------

and here are the additions I made to the build.xml file

Note: I inserted -dynamiclib, and -dynamiclib arguments because Mac OSX gcc
      doesn't support the -shared argument, and I saw somewhere on the web that these
      two arguments might work.

------------------------------------------------------------
    <property name="version.mac" value="${version.major}.${version.minor}.${version.micro}" />

    and


    <target name="macosx" depends="clean" description="--> Build ${build.shlib.mac.shlibname}">

        <exec dir="." executable="${build.mac.compiler}">

            
            <arg value="-v" />

            
            <arg value="-dynamiclib" />

            <arg value="-Wl,-soname,${build.shlib.mac.shlibname}" />

            <arg value="-I${build.mac.includes}" />

            
            <arg value="-I${build.mac.jni}" />

            
            <arg value="-dynamiclib" />

            <arg value="${build.shlib.srcname}" />

            <arg value="-o ${build.shlib.mac.shlibname}.${version.mac}" />

            <arg value="${build.mac.includes}/${build.lib.libusb}" />

            <arg value="${build.mac.includes}/${build.lib.libusbpp}" />

        </exec>

    </target>

  Hi Mike
  
  For your output I can only guess, that libtool has a problem with the -o option. Unfortunately I don't have a Mac and don't know how to build a shared library on OS X. I didn't find much documentation either. These are some links which may be helpful.
  Maybe you build some sample application first to see if it works in principal (first link). I'd also recommend to compile and build on the command line and not with the ant script...
  Maybe they can tell you how to build a JNI library in some MAC forum?
  
  Sorry for not being able to help. But if you get it to work, I'm very interested to include it into the build file...

  Hi Andreas,
  
  Thanks for the links. I hope to take a look at these this weekend.
  
  I'll keep you informed on my progress.

  Hey Andreas,
  
  I used your advice and built the LibusbJava without Ant on my Mac.
  
  Then I modified the build and property file according so Ant would work.
  
  Below is the modified build.xml file.

    Hi Mike
    
    I've included the changes in the trunk. Thanks for sharing!
    I assume the library works fine on the Mac then?
