Re: [opendx-dev] CLASSPATH and dxsamples

[Peter Daniel Kirchner <kirchner@ibm.net>]

Hi Tom,

Actually, we don't yet support kaffe for building javadx.  We took the javac -verbose route to automatically configuring the dx build which at the time precluded kaffe.  The dx configure leaves information for the dxsamples configure.  I bet we have not handled this correctly since this has changed in "dx" and we have not
re-rolled a dxsamples tarball. Ouch.

Workaround #0: go to the dxsamples Makefile and remove java from the SUBDIRS.
The remaining might not work because of my oversight explained in the first paragraph:
Workaround #1 : skip javadx, for dx, configure --without-javadx
Workaround #2: install jdk 1.1.8, I think there is an RPM for same, my favorite though is the IBM jdk, it may want IBM_LINUX set and JAVA_ARCH set to linux (vs. genunix ).

If you want to try to make dx build with kaffe, start by setting CLASSPATH (KLASSPATH?) to /usr/share/kaffe/Klasses.jar  prior to dx configure, and take it from there.

I'll investigate the dx/dxsamples build coordination and try to get a fix in soon.  Thanks for the append.

Pete
