CVC build fails in OpenLane

[hpretl]

When trying to update the CVC version used in OpenLane the CI build fails (Ubuntu 20.04.5) with this error message:

/bin/sh ../ylwrap cdlParser.yy y.tab.c cdlParser.cc y.tab.h `echo cdlParser.cc | sed -e s/cc$/hh/ -e s/cpp$/hpp/ -e s/cxx$/hxx/ -e s/c++$/h++/ -e s/c$/h/` y.output cdlParser.output -- bison -y -d -Wno-yacc

@hpretl Thanks for following up with this. I have a PR submitted to openlane, but it's not passing the CI and I have to investigate.

@donn has implemented a fix in https://github.com/The-OpenROAD-Project/OpenLane/pull/1440/files#diff-342331321bfc81580492bb90e88504b9f91888e1cbd60c5f78c6e2578d9615b0, I guess this solved the build issue:

sed -i 's/api.parser.class/parser_class_name/' src/cdlParser.yy

An issue I was only too familiar with, sadly. :)

Fixed with proposed WA, let’s close it.
