bison 1.34 incompatible with C++ compilers
Last modified: 2008-05-01 11:38:01 EDT
From Bugzilla Helper: User-Agent: Mozilla/4.78 [en] (X11; U; Linux 2.4.9-31 i686) Description of problem: Parsers generated with version 1.34 of bison cannot be compiled with C++ compilers when YYSTYPE is a class. This breaks many C++ projects that use bison. I recommend updating the package to bison 1.35 where the problem has been fixed. For all the gory details, see the given URL. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: An example of a project that breaks because of this: 1. Download GiNaC sources from www.ginac.de (and install CLN if you haven't already done so) 2. ./configure 3. rm ginsh/ginsh_parser.cc [to force a rerun of bison] 4. make Actual Results: Compilation in the "ginsh" directory fails with the message /usr/share/bison/bison.simple:75: member `GiNaC::ex yyalloc::yyvs' with constructor not allowed in union Expected Results: A clean compile (as is the case with bison-1.28-7 from RedHat 7.2). Additional info: For all the gory details, see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=130914&repeatmerged=yes
update 1.35 in rawhide, thanks
