When JNI headers for a given class, each nested class will end up with
its own additional header. But I don't want to try to parse nested
class details out of the Java source files just so we can determine
exactly which headers will be created. Instead, simply treat the
entire header destination directory as the output of this task.
Unlike Linux, macOS has no "RPATH" facility for embedding additional
search paths within shared libraries. Instead, we need to set
"DYLD_LIBRARY_PATH" appropriately in the environment. This
environment variable is the macOS analogue of "LD_LIBRARY_PATH" on
Linux.
Note that adding the required path to the "java.library.path" system
property will *not* work. This property only affects where the JVM
looks for shared objects that it is loading directly. This property
does not influence the search for other, transitively-required shared
objects.
Fixes#3.
I don't know whether Windows or MacOS needs anything similar. If they
do, the details will differ, and should be handled by adding suitable
cases to these switch statements.
Dependencies are still not set properly here, so you need to have
built the shared library ("./gradlew xlator_testSharedLibrary") before
running the ":com.ibm.wala.cast.test:test" test task. But at least
the tests do now find and load that shared library properly.
I was confused about the differences among:
srcDir 'foo'
srcDirs ['foo']
srcDirs = ['foo']
As it turns out, the first two append to the set of source
directories, while the last replaces this set entirely. I generally
want replacement, since WALA's current directory layout never matches
Gradle's assumed defaults.
