Re: compiler error .hh file

[Gilberto Monroy]

Akim:
1 Yeah, you are right, I removed the .h and .hh files from the compilation
line, but the result is the same.
2 Actually, the .hh file is included in rcss_driver.h, wich is included in
rcss_parser.y. John is right, there are inclusion guardas in the .hh file,
that is not the problem. I changed the code a bit in a way I do not
(directly or indirectly) include  the .hh file in the .y file, but the
result is similar:

g++ -o parser  rcss_parser.tab.cc lex.yy.c rcss_parser_driver.cpp -lfl
