[antlr-interest] Re: ANTLR cpp-generated example crashes on Cygwin

[Dario Gonzalez]

OK, I know why the snapshot didn't build: There is a bunch of missing
*.class files in the antlr/ dir (among them the antlr.Tool class)
which are present in the 2.7.2 version.

I used "bootstrap" make's target to generate them and now I have the
test-snapshot working in Cygwin. I had to modify script/config.make's
ANTLR_BOOTSTRAP variable (similar to the Cygwin-working-recipe):

ANTLR_BOOSTRAP = $(JAVA) -cp "<windows/path/to/your/antlr.jar>" \ 
       antlr.Tool

Hope this one works... if don't, be sure I'll be here soon.


Thanx
