Force bison invocation to include -d flag so that yac.h is rebuilt. The copy supplied in the 2.2.11 distribution does not have the same symbol numbering that's generated by current Bison, and so the lexer is out-of-step with the grammar if it just uses that version. This results in complete failure of the sqp library, leading to reported problems with text-file driver (bz #162676). diff -Naur unixODBC-2.2.11.orig/sqp/Makefile.am unixODBC-2.2.11/sqp/Makefile.am --- unixODBC-2.2.11.orig/sqp/Makefile.am 2004-09-13 08:30:29.000000000 -0400 +++ unixODBC-2.2.11/sqp/Makefile.am 2005-09-29 15:19:52.000000000 -0400 @@ -1,3 +1,5 @@ +AM_YFLAGS = -d + if HAVE_FLEX noinst_LTLIBRARIES = libsqplc.la
