Compiling verilator in Freebsd
Added by Otacílio de Araújo Ramos Neto about 4 years ago
I'm trying compile verilator in FreeBSD but I´m getting a problem.
When I type gmake after .configure the compile starts, but stop with a error.
/usr/local/bin/flex -d -oV3Lexer_pregen.yy.cpp ../verilog.l
/usr/local/bin/perl ../flexfix <V3Lexer_pregen.yy.cpp >V3Lexer.yy.cpp
g++ -I/usr/local/include -MMD -I. -I.. -I../../include -DYYDEBUG -ggdb -DVL_DEBUG -c ../V3Read.cpp
In file included from ../V3Read.cpp:39:
V3Lexer_pregen.yy.cpp:385: error: no 'int V3LexerBase::yywrap()' member function declared in class 'V3LexerBase'

Googling for that problem suggests it's really a flex problem. I just installed flex 2.5.35 on Cygwin and it works OK, so the base version of flex is ok, so it's probably Mac/BSD specific.
Can you attach the V3Lexer_pregen.yy.cpp file? Also somewhere on your system is FlexLexer.h (most likely /usr/include/FlexLexer.h) please include that too.

they are attached
V3Lexer_pregen.yy.cpp (230.6 kB)
FlexLexer.h - /usr/local/include/flex/FlexLexer.h (6.1 kB)
RE: Compiling verilator in Freebsd - Added by Wilson Snyder about 4 years ago
The error you report doesn't make sense given the FlexLexer file you sent. Please search your system for ANOTHER FlexLexer.h; I believe it's getting confused because there's multiple versions of FlexLexer.h

Yes Wilson!
I find another FlexLexer in /usr/include I moved it to FlexLexer.h.old and try another ./configure, but the error occours again, then I create a link to /usr/local/include/flex/FlexLexer.h, run ./configure and the compilation works OK!
I will verify about the file /usr/include/FlexLexer.h
Thanks
