The patched source is capable of building natively and cross - tested prior to filing the bug report. >> Note that libjpeg6b needs to be told about the cross-compiler in >> --build and --host as well as in the $(CC) variable to configure, it >> also requires $(CC) to be set to the cross compiler for each of the >> $(MAKE) commands.

Emdebian will not be using emulators - it's all to be cross built from Debian sources. I also disagree on the reliability of emulators but that's by the by. http://www.emdebian.org/ -- Neil Williams ============= http://www.data-freedom.org/ http://www.nosoftwarepatents.com/ http://www.linux.codehelp.co.uk/
