Flex++ in Ubuntu (Linux)

  1. Apr 29, 2007 #1
    I just loaded Ubuntu (Linux) onto a spare hard drive. It was relatively painless. I am posting this message from it.

    I am having a problem with using Flex++. I wonder if anyone has come up against this before. The .L and the Makefile are quite small and I could post them if it would help. However, the error message is:

    /usr/include/FlexLexer.h:113: error: redefinition of ‘class yyFlexLexer’
    /usr/include/FlexLexer.h:113: error: previous definition of ‘class yyFlexLexer’

    and I wonder if that is enough to go on for a first stab. It looks to me as if there were two "#include <FlexLexer.h>" directives hanging around and not properly protected with "#ifndef yyFlexLexer" directives in the .h file. If I remove the "#include" directive from my .L file, I get too many error messages.
