Hi, everyone. I'm porting GCJ to a non-mainstream platform, which is a RISC machine with some similarity to ARM. The GCC I'm using is version 4.4.2. I start the porting from ARM's code. When running the GCJ on the target platform, it mentioned that the ECJ is needed. I don't know whether GCJ can live without ECJ, so I donwload the latest ECJ jar file and recompiled. When running GCJ to compile a JAVA source file, I got the following error. [root@localhost pxx]# gcj -C HelloWorld.java -v Using built-in specs.

I really appreciate you patience.
