Presumably the the media player will need to talk to the Sigma libraries (using JNI), so the JVM will need to be compiled with their compiler. (actually there is an alternative - wrap the the libraries in a C program which receives commands from the Java part via a socket. But that's getting complex.) I'm pretty sure Mika can still be compiled with gcc 2.95.3, J9 might be more problematic - but if it's physically possible the Apogee guys can do it. :-) > [Jonathan Wong == OP] > > I need to create a media player and include web connectivity (very thin > > web client).

Most of our customers' devices seem to have between 32 and 64 megs of RAM, so this doesn't sound like an insuperable problem. The JVM will probably allocate its heap in one go, and then it's up to the garbage collector to fight against fragmentation. -- Chris Gray /k/ Embedded Java Solutions BE0503765045 Embedded & Mobile Java, OSGi http://www.k-embedded-java.com/ chris.g...@kiffer.be +32 3 216 0369 Come and see us at Embedded World 2009 in Nürnberg, 3-5.3.2009: Hall 12, Stand 560 (DSP Valley). http://www.embedded-world.de/ _______________________________________________ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
