Andreas,

I would like to request your assistance on the following 'CMake' issue requested by Adam:

• https://fedorahosted.org/pki/ticket/9

Basically, on Fedora 16 and later, the default location of Java Native Interface (JNI) jar files was changed to reside under '/usr/lib/java' for 32-bit platforms, and '/usr/lib64/java' for 64-bit platforms.

Per the TRAC ticket, I made a change in the spec files to handle this via the 'jpackage-utils' RPM. However, I do not know if 'CMake' can change the 'JAVA_LIB_INSTALL_DIR' macro located in the 'pki/cmake/Modules/DefineInstallationPaths.cmake' file to rely on the '%{_jnidir}' macro of 'jpackage-utils' stored in the '/etc/rpm/macros.jpackage', or if there is a different way of handling this where the following logic comes into play:

• '/usr/lib/java' on RHEL 6 and earlier (32-bit AND 64-bit platforms)
• '/usr/lib/java' on Fedora 15 and earlier (32-bit AND 64-bit platforms)
• '/usr/lib/java' on Fedora 16 and later (32-bit platforms)
• '/usr/lib/java' on Fedora 16 and later (using a 32-bit JVM on 64-bit platforms) o I am fairly confident that this case may actually REQUIRE a compiler override, as it does not look as if 'jpackage-utils' computes its '%{_jnidir}' macro based upon the 'JVM' architecture being utilized, but rather the '%{_libdir}' macro based upon the operating system architecture located in the appropriate '/usr/lib/rpm/platform/<platform>/macros' file
• '/usr/lib64/java' on Fedora 16 and later (64-bit platforms)

Your assistance on this matter is greatly appreciated.

Eventually, do you think that we may want the appropriate logic added to the '/etc/rpm/macros.cmake' file?

Thanks, -- Matt
