[Boost-users] Problems with file_iterator and skip parsers

From: chrono232_at_[hidden]
Date: 2005-02-27 02:25:30

Can anyone explain to me what is wrong with the following:

----------------

my_grammer g;  // a grammar, the actual grammar I'm using is too long 
for me to post
file_iterator first<char>( "somefile.txt")
file_iterator last<char> = first.make_end();
rule_t<> skp = space_p | comment_p("//") | comment_p("/*","*/");
parse_info< file_iterator<char> > = parse( first, last, *g, skp );

----------------

I keep getting these errors (from MinGW 3.4.2):

189 C:\Dev-Cpp\include\boost\spirit\core\non_terminal\impl\rule.ipp

According to the FAQ, this shouldn't happen with grammars.  I am a 
beginner, so please forgive my ignorance.  Thanks for any and all help.

Also, I've tried making the skip rule a grammar, again, with errors.
