Hi,

After working around bug #34663, I hit the following build error:

gmake[3]: *** [liboctinterp_la-builtins.lo] Error 1


Notice this line:

builtins.cc:25117:2: error: #error lex.l requires flex version 2.5.4 or later


The default OpenBSD lexer is:

% flex --version
flex version 2.5.4


And I have also tried:

% gflex --version
gflex 2.5.35


So the error seems wrong.

The other thing that surprises me here is that we appear to be building lexer
input with g++. Is this some GNU extension that OpenBSD does not understand?
Having said that I am using gmake, flex, gcc/g++; all GNU tools.

Help would be most appreciated.

See bug #34663 for a config.log.

This is OpenBSD-current on amd64.

Cheers
