I've noticed that on AIX, a shared library is initially built as an .so file via "gcc -shared", but then this .so is packed up into an .a file using ar(1). This is the case even if -export-dynamic -module is specified. When I go to use these JNI modules, however, the JRE makes very clear that it doesn't like .a files: Exception in thread "main" java.lang.UnsatisfiedLinkError: jni_test ( 0509-022 Cannot load module /tmp/jni/libjni_test.a. 0509-103 The module has an invalid magic number.) at java.lang.ClassLoader.loadLibraryWithPath(ClassLoader.java:994) at java.lang.ClassLoader.loadLibraryWithClassLoader(ClassLoader.java:958) at java.lang.System.loadLibrary(System.java:453) at com.example.jnitest.JniTest.<clinit>(JniTest.java:21) at java.lang.J9VMInternals.initializeImpl(Native Method) at java.lang.J9VMInternals.initialize(J9VMInternals.java:196) at JniTest.main(JniTest.java:56) If I extract the .so files from the .a files, however, the JRE happily uses those. Currently, I am using an install-exec-hook rule to perform this step during "make install". There does not appear to be a Libtool option to skip the use of ar(1), which would be a preferable approach. --Daniel -- NAME = Daniel Richard G. _\|/_ Remember, skunks MAIL = skunk@HIDDEN (/o|o\) _- don't smell bad--- MAIL+= skunk@HIDDEN < (^),> it's the people who WWW = (not there yet!) / \ annoy us that do!

This bit from doc/notes.txt in the Libtool source distribution seems relevant: * On AIX there are two different styles of shared linking, one in which symbols are bound at link-time and one in which symbols are bound at runtime only, similar to ELF. In case of doubt use `LDFLAGS=-Wl,-brtl' for the latter style. Why isn't Libtool itself already adding this flag when -module is specified?
