Created attachment 826751 [details] build.log sys-devel/reflex is a fork of the original flex (of which sys-devel/flex is itself a fork -- so sys-devel/reflex & sys-devel/flex both share ancestry with a common, older 'flex'). I've not encountered any actual compatbility problems with it yet and it's quite nice as it compiles with no warnings and such. Anyway, with FLEX="reflex" set in make.conf, I get this with dev-util/cdecl: ``` checking for library containing yywrap... -lfl checking whether yytext is a pointer... yes checking if flex is the lexer generator... no configure: error: required program "flex" not found !!!

It's because configure.ac is aggressively checking for flex specifically rather than a POSIX lex: https://github.com/paul-j-lucas/cdecl/blob/ae9841f2ce4d9b924b834d806590351a54057f6c/configure.ac#L55. I wonder if that's really needed. I feel like AC_PROG_LEX should be enough most of the time, rather than the used AX_PROG_FLEX. If you have a better idea for how I should be setting reflex, let me know though.
Similar issue with YACC="byacc" in make.conf :(
