[antlr-interest] antlr-2.7.7: Compilation failed (Linux openSuse 10.2)

[Francisco Javier Santa Eugenia]

Hello, 
I am trying to compile antlr-2.7.7 on openSuse Linux 10.2, but the compilation 
failed with `make install` (. Here are the messages:
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
>> /usr/bin/make -C lib/csharp/antlr.runtime install
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

I probably made a mistake but I do not understand where.
Can someone help me?
Thank you in advance!
