Any idea how to fix this? I have a grammar which compiled without
problems on bison 2.4.1/gcc 4.4.7 (RHEL 6.5), but which won't now
compile on bison 3.0.2/gcc 4.8.2 (Ubuntu 14.04).
The bison.tab.cc output from 2.4.1 included a definition of yylval as:
semantic_type yylval;
The 3.0.2 output has no definition, and the compiler complains when it
reaches the first reference to yylval in the new bison.tab.cc, saying
that "'yylval' was not declared in this scope." This corresponds to my
first use of 'yylval' in my .y file.
I'm using the C++ skeleton (lalr1.cc), and not explicitly declaring a
pure-parser.
http://stackoverflow.com/questions/23685843/problems-with-yylval-and-yylloc-after-switching-to-bison-3-0
is the same question on stackoverflow, from May 15th, with a suggestion
to use yyla.value instead.
Thanks.
