It is an interesting exercise... Tools.jar is required, if you want to
run <javac/> in process, otherwise you can specify <javac
fork="true".../> and external compiler will be used (for example,
jikes). Another possibility is to compile tools.jar into native code
(not sure whether gcj can do it and maybe it is illegal, because gcj
would have to decompile bytecode in order to generate native code and I
doubt you will have rights to redistribute the results).

Hi,

Trying to use the ant binaries doesn't work either: ant -version results in
Unable to locate tools.jar. Expected to find it in /usr/lib/tools.jar
Apache Ant version 1.6.5 compiled on June 2 2005
AFAICT gcj doesn't have a tools.jar file.
Any ideas on this?
Thanks,
bero
