Unable to compile on debian sid

Following the directions on the readme results in this error:

$ make
make  all-recursive
make[1]: Entering directory '/home/hathaway/src/bic'

looks like I need to generate the lang_lexer.h file, how do I do that?

~I think it's been mistakenly placed in the .gitignore file. So it's not there.~

Hi there, lang_lexer.h is generated by flex. Looking at your compilation output it doesn't appear to be installed:

: --header-file=cfilelex.h -o /dev/null cfilelex.l

should be

flex --header-file=cfilelex.h -o /dev/null cfilelex.l

Maybe try apt-get install flex?

awesome, that fixed it!
