Where is Java Runtime Engine rt.jar on a Mac

jjmckenzie51

All:

I have been working on a clean build for OOo X11 and found the following in the MacOSX.env and Macosx.Env.sh files:

CLASSPATH=/System/Library/Frameworks/JavaVM.framework/Home/jre/lib/rt.jar

I know what the file is and it's purpose in life. However, I've had continuous problems building the udkapi project/package. I think it is associated with an improper setting. Also, is this file actually used in/on a Mac build?

And at the present time, I am working on a rebuild of my PBG4 by installing Tiger with a reformat of the hard drive.

Yes, the rt.jar is used in the build. I'm not sure whether or not that CLASSPATH is used for the java VM that's invoked to run ant or the other Java tools in the build or if it's passed to javac on the command line. Either way the path should be set correctly. I'm not sure if the framework paths are changed on Tiger; I haven't installed the 1.5 update either. I also honestly haven't done my full OOo X11 builds on Tiger yet myself as whenever I do the X11 build (either standalone or substrate) I flip back to 10.2. I know if I build it on 10.2 I won't be introducing any dependencies that prevent it from running on newer OSes.

Just a wild random guess (since IANADev): do you have all of the relevant SDKs installed? I know once when I did an XCode/devtools update I had to grab a Java SDK to keep things in sync with the Java version installed on my Mac....

Edit: Yeah, don't think that's it, because I don't have the file on 10.3.9 + XCode 1.5 + X11 SDK and whatever Java SDK that was.... I know I don't have all the deps to build OOo, though....

I'm on Tiger (MacOSX 10.4) and installed the Java SDK (1.4.2_07) and it was not there. I definately would not want to install a complete J2SDK in order to run java programs. I think this is a serious oversight on Apple's part unless they have another method to invoke the Java RunTime engine (that's what is in the rt.jar file.)

To build NeoJ, for sure you need to have the Java SDK installed to get the headers to embed VMs into other processes. OOo as well does do embedded VMs, and 2.0 in fact requires them for Base, the wizards, etc. In order to build them you'll need to get the Java SDK.

I think they took Patrick's 1.4 Java support into OOo 2.0, but I don't know since they have orphaned/abandoned many of his other patches Sad

You may need to get the 1.3 JDK.

Ok. I don't know if there is a 1.3 SDK for Tiger. I'm looking at Patrick's patches for NeoOffice and I'm also looking at some gcc 4.0 patches in addition. It may be that OOo and NeoOffice are using the 'wrong' compiler too.

Yes, definitely stick with gcc 3.3 for now (the same version that was the last version on Panther). The gcc_select command actually switches which version is used when you just type "gcc" at the command line...as well as all of the libraries and headers that get used for the stdlib and runtime as well. I don't know if anyone within OOo has bothered compiling on gcc 4 yet. From moving between gcc 2 and gcc 3, I expect there to be problems. I believe the C++ ABI changed with gcc4 which will mean some gnarly assembly UNO work will need to be done. Keep an eye on Kevin & LinuxPPC as it's essentially the same compiler and he's got mad skills. He's done our OS X ABI work in the past Smile

Yes, I've been tracking the latest on the IZ. Looks like Kevin is real busy and squashing gcc 4.0 'bugs'. I will stick with cc/c++ for now as it appears that gcc is still 'broken' and does not want to work correctly in some situations.
