Hi John,
Did you git pull first? This changes quickly! :-).
Thanks,
Antonio

Hallo Antonio,
so, basically the error is that it cannot handle escape characters, e.g. \".

Thanks John,
I'll be adding assorted compiler-specific cases at [1].
Kind regards,

After pulling, building, re-running: java -Dlexer.print=false -jar

I get

Please report this error on the dev mailing list, including the line
where
the error happeened.%n

Hi John,
Thanks for the report! It seems we weren't lexing '#error' yet (that's
probably what is on line 59 in "/usr/include/complex.h", right?
Otherwise send me the line 59).
The newest version should detect #error properly (and also checks for
ends of directives, and *.hpp/*.cpp).
Talking about antlr4, it seems the AST is analyzed using the visitor
pattern (that approach is also used in libclang) but NetBeans <= 8.2
expects the whole AST in memory, so it seems we have a long refactoring
road ahead (all this after successfully migrating the CXXParser.g to
antlr4, which reads >3300 lines long).
In parallel I'm giving libclang [1] a run. It seems quite powerful (it
provides completion, precompiled headers, reparsing, diagnostics, AST)
but it may require an extra +30Mb download on Windows (linux users may
apt-get install libclang, though). More on this in a few days.
Thanks again,
Antonio

Will also take a look. Thanks Antonio. Great initiative.
P.S. I guess .hpp/.cpp files are next?
