I'm working through Intrusion Detection With BASE And Snort tutorial (http://www.howtoforge.com/intrusion_..._base_snort_p3) on Ubuntu. I ran into a problem at make/install LIBPCAP (page 3). When I execute make, I get the error shown below. I included the last 4 lines of output from make: lex -t scanner.l > $$.scanner.c; mv $$.scanner.c scanner.c yacc -d grammar.y make: yacc: Command not found make: *** [grammar.c] Error 127 Can anyone help me figure out what to do now? How do I install bison so the libpcap configure script finds it? Right now bison is installed in the snorttemp/bison-2.3 directory (see article). It's at the same level as libpcap. Bruce
What's the output of Code: apt-cache search yacc ? You can install bison like this: Code: apt-get install bison
apt-cache search yacc output Output from apt-cache search yacc output: bison - A parser generator that is compatible with YACC byacc - public domain Berkeley LALR Yacc parser generator cup - LALR parser generator for Java(tm) exuberant-ctags - build tag file indexes of source code definitions gob2 - GTK+ Object Builder libtimedate-perl - Time and date functions for Perl pccts - The Purdue Compiler Construction Tool Set (PCCTS). bison-1.35 - A parser generator that is compatible with YACC btyacc - Backtracking parser generator based on byacc cl-yacc - parser generator for Common Lisp cscope - Interactively examine a C program source cutils - C source code utilities freebsd5-buildutils - Utilities for building FreeBSD 5.x sources global - Source code search and browse tools gob - GTK+ Object Builder gobo - Portable Eiffel tools and libraries gobo-doc - Portable Eiffel tools and libraries (Documentation) happy - Parser generator for Haskell jflex - lexical analyzer generator for Java kimwitu - Compiler development tool, complementary to lex and yacc. kimwitu++ - A (syntax-)tree-handling tool (term processor) kimwitu-doc - Documentation for compiler development tool kimwitu lemon - The Lemon Parser Generator libparse-recdescent-perl - Generates recursive-descent parsers in Perl libparse-yapp-perl - Perl module for creating fully reentrant LALR parser OO Perl modules ml-yacc - Parser generator for Standard ML perl-byacc - The Berkeley LALR parser generator, Perl version python-pyparsing - Python parsing module python2.3-pyparsing - Python parsing module python2.4-pyparsing - Python parsing module racc - Ruby LALR parser generator sloccount - Programs for counting physical source lines of code (SLOC) styx - combined parser/scanner generator for C/C++ wyg - (Where's Your Grammar?) command line parser generator mono-jay - LALR(1) parser generator oriented to Java/CLI
Got LIBPCAP make to work once bison installed My previous problem with yacc was resolved when I installed bison. I was able to make and make install LIBPCAP. Thanks for the help.
