             Summary: sis-gdal module should not write native file in the temporary directory
                 Key: SIS-366
                 URL: https://issues.apache.org/jira/browse/SIS-366
             Project: Spatial Information Systems
          Issue Type: Bug
          Components: Storage
    Affects Versions: 0.8
         Environment: Linux, MacOS
            Reporter: Martin Desruisseaux
            Assignee: Martin Desruisseaux
             Fix For: 0.8


The {{sis-gdal}} module uses Java Native Interface (JNI) for accessing the Proj.4 library. Currently, the JNI are pre-compiled in {{storage/sis-gdal/src/main/resources/native/<OS>/libproj-binding.so}} files where {{<OS>}} is {{linux}} or {{darwin}}. The file size is about 14 kb. Since we can not load a library from a JAR file, we have to copy it as a regular file somewhere. Current implementation copies it in the temporary directory.

Problem is that some environments do not give execution permission in the temporary directory. Consequently we should save the {{libproj-binding.so}} files somewhere else. Some possibilities are:

1. Platform-specific directory like {{<user directory>/Library}} on MacOS.
2. A sub-directory of {{$SIS_DATA}}.
