Problem compiling apache libraries

Thanks for the reply.
I could compile those libs with that option.
By compiling jar files into object files, I'll no more need to add
those jar files in classpath, right?
Now, I want to compile the whole project into a single executable
file. I use the following commang line:
gcj --main=MainClass -findirect-dispatch apache-commons.o
log4j-1.2.8.o swt-win32.o velocity-tools-generic-1.2.o velocity-1.4.o
zekr.o
where all the needed runtime jars added as .o file, but GCJ gives a
lot of error messages complaining "undefined reference to
XYZ::class$$'"
e.g.
swt-win32.jar:(.data+0x2f110): undefined reference to `_ZN
3org7eclipse3swt8internal8Callback4bindEJiPS3_PN4java4lang6ObjectEPNS6_6StringESA_ibbi'
Is there any trick to bypass these reference errors?
Thanks.
