I'm trying to make tomcat-4 work with gcj. I installed gcj , rhug , special tools. I got gcc 3.3, anyway that is supposed to work with tomcat. I got an error when doing "make" Can't find constructor in Generator.java In my program, I got an error "new ParamVisitor(sep)" I made similar but small program. I got the same error. Then, I compiled the program with javac and it was OK. Do you think that gcj still has some problems? or didn't I succeed in configuration? I don't know if this e-mail is appropriate for my question. Would you please give me some advice?
