在SWT插件中打包GDAL JAVA绑定和本机库

我想将GDAL及其JAVA绑定打包到SWT插件中。 (P.S. GDAL使用swig生成Java绑定)

我拥有所有必需的本机库,并希望将它们打包到我的Eclipse插件中,让其他人使用它而无需在计算机上安装GDAL。

问题是JAVA绑定(或本机lib本身)将从 PATH (窗口)或 LD_LIBRARY_PATH (Linux)查找必要的本机库,而不是查找这些库在相对位置。此外,GDAL还将从环境变量 GDAL_DATA 中查找一些必要的地理定义数据。

如何解决这两个问题以制作便携式SWT插件? 1)包平台特定的本机库 2)一些环境变量查找

似乎eclipse无法在没有设置PATH的情况下解析依赖的lib。 Bundle-NativeCode(见下文)不起作用。

如果我尝试直接在我的插件中调用System.Library(“SomethingNotExist”); 然后我得到

java.lang.UnsatisfiedLinkError: no SomethingNotExist in java.library.path

如果我在插件中调用System.Library(“SomethingDoesExist”),那么我

java.lang.UnsatisfiedLinkError: SomethingDoesExist.dll: Can't find dependent libraries

插件中的文件结构

org.gdal/
   + src/
   + nativelib/
      + linux32/
        + ...
      + linux32/
        + ...
      + win32/
        + ...
      + win64/
        + ...
   + META-INF
      + MANIFEST.MF
   + gdal-data/
   + gdal.jar
   + build.properties

此插件的build.properties

source.. = src/
output.. = bin/
bin.includes = META-INF/,\
               .,\
               gdal.jar,\
               gdal-data/,\
               nativelib/

关于Java中GDAL的环境问题

使用gdal.SetConfigOption

http://osgeo-org.1560.n6.nabble.com/gdal-dev-GDAL-DATA-td3744017.html

将GDAL_DATA设置为可以从插件包中读取的文件夹。
