Hi,
for opensc and related projects we came to the conclusion
it is best to require the user to install libltdl.so and
header files, and then link to that library.
Is there a recommended way to implement this in autoconf?
In the documentation it looks like all scenarios copy
libltdl into the source, but we don't want to do that.
In OpenLDAP's configure.in we use
AC_CHECK_HEADERS(ltdl.h)
if test $ac_cv_header_ltdl_h = no ; then
AC_MSG_ERROR([could not locate libtool ltdl.h])
fi
AC_CHECK_LIB(ltdl, lt_dlinit, [
MODULES_LIBS=-lltdl
AC_DEFINE(HAVE_LIBLTDL,1,[define if you have libtool -ltdl])
])
if test "$ac_cv_lib_ltdl_lt_dlinit" = no ; then
AC_MSG_ERROR([could not locate libtool -lltdl])
fi
