ax_lib_tabix

Synopsis

AX_LIB_TABIX()

Description

This macro searches for an installed tabix library. If nothing was specified when calling configure, it searches first in /usr/local and then tries with ld’s default library search path. If the –with-tabix=DIR is specified, it will try to find it in DIR/include/tabix/tabix.h and DIR/lib/libtabix.a. As a final try it will look in DIR/tabix.h and DIR/libtabix.a as the tabix library does not contain an install rule.

If –without-tabix is specified, the library is not searched at all.

If either the header file (tabix.h) or the library (libtabix) is not found, the configuration exits on error, asking for a valid tabix installation directory or –without-tabix.

The macro defines the symbol HAVE_TABIX if the library is found. You should use autoheader to include a definition for this symbol in a config.h file. Sample usage in a C/C++ source is as follows:

  #ifdef HAVE_TABIX
  #include <tabix.h>
  #endif /* HAVE_TABIX */

The following output variables are set with AC_SUBST:

  TABIX_CPPFLAGS
  TABIX_LDFLAGS
  TABIX_LIBS

You can use them like this in Makefile.am:

  AM_CPPFLAGS = $(TABIX_CPPFLAGS)
  AM_LDFLAGS = $(TABIX_LDFLAGS)
  program_LDADD = $(TABIX_LIBS)
