The ebuild just scans for all java files and puts them together with the installed jars found on the system into one big command line to call javac. This command line has too many arguments on my system (which has only 4(!) jars in the classpath). The ebuild should be changed to compile azureus so that the commandline is not 1 mile long. :) Reproducible: Always Steps to Reproduce: 1.emerge azureus >2.x 2. 3.

Created attachment 136761 [details] the created command line that is way too long

AFAIK there is no limit in the bash shell regarding cmd line limit and so I guess javac is complaining of the command line itself. I don't know of any setting for javac as well that I could improve. Do you? So the only difference I can imagine are the 4 jars I have additionally in my classpath. But that's a very small part of the command line, which would mean your command line is near the limit, too. So putting it in a temp file seems to be a good idea, I guess.

I have not changed any settings regarding the number or size of arguments in my shell, I still get this bug. I've been using azureus since forever on gentoo, and haven't run into this kind of problem before. Anyone got a temporary solution?

I suppose ant is better way.

Anyone got a temporary > solution? > The max command line length is a constant compiled into the kernel, so the only way to increase the maximum command length for your system is to go and hack the value: /usr/src/linux/include/linux/binfmts.h:#define MAX_ARG_PAGES 32 to something larger and rebuild your kernel. It's not even an option in the kernel .config file. Seems a bit extreme to get this ebuild to work. Using ant would probably help, or doing something like: find . -name \*.java | xargs javac not exactly elegant, but gets around the command line limitation.
Created attachment 136807 [details] patched ebuild that fixes the too long argument bugs this ebuild writes the files to process into temporary files and calls the java and jar commands with @<tempfile>
Fixed with a slightly modified way. Thanks. In the future please post patches, not whole ebuilds.
