Original Redmine Issue: 1329 from https://www.veripool.org

./configure runs without issue, but make fails with the below message. I have tried newer versions of flex/bison, but cannot figure how to solve.

Sorry you are having problems.

What OS version?

What flex version?

What is the code around the lines the compiler is complaining about?

from ../V3ParseLex.cpp:37:
/usr/include/FlexLexer.h:130:14: error: expected unqualified-id before numeric constant

I think this is the line it is complaining about:
virtual int yywrap();

What distribution, e.g. Ubuntu 18.04, etc. (uname is the kernel version which doesn't say the distro.)

You must in a big company to use an almost 10 year old distribution ;) Do they know that SuSE 11 general supports ends in a few months?

Anyhow I don't have a license so you'll need to debug yourself, if you're not sure how to do this ask someone in your organization that knows C++. Look at the sources around line 140 of /usr/include/FlexLexer.h:13, and also at V3Lexer_pregen.yy.cpp around line 3456.

Note on a hunch I tried using SEL 6.9 which is generally the same as RHEL 6.9, and it worked without issues, so you're still stuck to debug this locally, sorry.

Did you have any luck debugging this, or working around it?

Please close. I copied a Linux redhat build over to Suse and it worked.
