Well, it's hard to tell, because it was a lot of different errors, wich I tried to solve. For now, I'm stuck with this one:
In file included from flagStonePort/translate-as1/translate-asl/ActionScriptLexer.cpp:2:
flagStonePort/translate-as1/translate-asl/ActionScriptLexer.hpp:4:28: error: antlr/config.hpp: No such file od directory
flagStonePort/translate-as1/translate-asl/ActionScriptLexer.hpp:6:33: error: antlr/CommonToken.hpp: No such file od directory
flagStonePort/translate-as1/translate-asl/ActionScriptLexer.hpp:7:33: error: antlr/InputBuffer.hpp: No such file od directory
flagStonePort/translate-as1/translate-asl/ActionScriptLexer.hpp:8:28: error: antlr/BitSet.hpp: No such file od directory
and so on...
I've figured out, that I need to install antlr tool, but it's made for maven utility, and I have no clue to get maven work on my desktop...
