rapicorn 17.0.0 not building on archlinux

[kolewu]

I have tried to compile rapicorn 17.0.0 under current archlinux. Since it has very recent versions of all tools and libraries, I have expected some problems. But since I'm not very comfortable with flex and bison, I can't make any sense of these error:

  CXX      ui/ui_librapicorn_17_la-sinfex.lo
ui/sinfex.cc: In function ‘int {anonymous}::bison_yylex({anonymous}::BISON_YYSTYPE*, {anonymous}::BISON_YYLTYPE*, void*)’:
ui/sinfex.cc:419:1: error: redefinition of ‘int {anonymous}::bison_yylex({anonymous}::BISON_YYSTYPE*, {anonymous}::BISON_YYLTYPE*, void*)’
 bison_yylex (YYSTYPE *yylval_param, // %union from sinfex.y
 ^~~~~~~~~~~

ui/sinfex.cc:428:16: error: ‘flex_yylex’ was not declared in this scope
   int result = flex_yylex (yylval_param, yylloc_param, yyscanner);
                ^~~~~~~~~~

To come to this point, I have to make the following changes:

and call configuration with

I'm not sure, why my version of flex 2.6.4 barks upon ansi-definitions and ansi-prototypes, even if the manual (for the same version) states, that they are deprecated and ignored.

Thanks for giving an arch build a try Uwe. I've not seen that error before (using flex 2.6.0 here). Is there an arch Dockerfile somewhere that I could use to reproduce this?
