Hi, I was looking at the genius OJ start script and thinking about if the result of the detection of native library path is useful or not. Now the native library is set on Windows according to processor architecture and OS version strings. The resolution is better than anywhere else I have seen. Usually there are Windows downloads only for x86 and amd64 but OJ can resolve not only processor architecture but also if OS is XP, Vista, Win 7, Win 8, or Win 8.1.
For GDAL binaries there is an override that detects the jre version first and uses only two alternatives for native library locations: if DEFINED JAVA_X64 ( set "GDAL_FOLDER=gdal-win-x64" ) else ( set "GDAL_FOLDER=gdal-win-x86" Spatialite binaries which I have been playing with are built in a similar way than GDAL binaries. If 32 bit jre requires 32 bit versions from the binaries and 64 bit jre requires 64 bit binaries. The problem is that if I run 32-bit jre on 64 bit Win 7 then OpenJUMP is searching native binaries from directory \lib\native\seven64\. As a workaround I can place the 32 bit binaries there or into \lib\native\ which is also on the search path. But if I plan to plan to run sometimes OJ with 32 bit jre and sometimes with 64 bit jre both these options are poor and I must move some dll files before starting OJ with another jre. BTW. I have experienced the dll hell: Native GDAL and Spatialite binaries can't be used simply together with OpenJUMP because Spatialite depends on GDAL and versions do not match. How about making the search path as follows: 1: jre specific general dll path, either win-x86 or win-amd64 2: special folder for GDAL binaries, search from gdal-win-86 or gdal-win-x64 (Ede has used names x86 and x64; should be decided which names to use and unify the batch file) 3: Operating system + processor architecture based fine grained native folders An untested modification to oj_windows.bat starting from row 142: rem -- set general win32 / win64 vars -- rem -- set GDAL vars -- if DEFINED JAVA_X64 ( set "WIN_DLL_FOLDER=win-amd64" set "GDAL_FOLDER=gdal-win-x64" ) else ( set "WIN_DLL_FOLDER=win-x86" set "GDAL_FOLDER=gdal-win-86" ) set "GDAL_FOLDER=lib\native\%GDAL_FOLDER%" set "WIN_DLL_FOLDER=lib\native\%WIN_DLL_FOLDER%" if EXIST "%GDAL_FOLDER%" ( set "GDAL_DATA=%GDAL_FOLDER%\bin\gdal-data" set "GDAL_DRIVER_PATH=%GDAL_FOLDER%\bin\gdal\plugins" rem --- prioritize jre version specific binaries in the path --- set "PATH=% WIN_DLL_PATH %;%GDAL_FOLDER%\bin;%GDAL_FOLDER%\bin\gdal\java;%PATH%" rem --- gdal binding is version specific, prioritize the one delivered with native libs --- set "CLASSPATH=%GDAL_FOLDER%\bin\gdal\java\gdal.jar;%CLASSPATH%" ) -Jukka- ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
