Really don't know...

I only remember we depend on flex (plain old lex may not work).

I do not have the trouble even I have the exact same version
of bison and flex AND gcc.

But don't you build in-source?

Could you try an out of source build.
The tsp_ascii_writer_config_yy.c should be generated in the
build tree from tsp_ascii_writer_config.lex.

The in-source
tsp/src/consumers/ascii_writer/tsp_ascii_writer_config_yy.c

may not match your flex version.

on my box generated file and in source file are really different.
