I know this is a very basic question, and I hope not too off topic. I'm
new to this.
I'm looking for an example use of autoconf to optionally use a shared
library, and what to instructions to give when the library is installed in
a non-standard location. I'm wondering if there's a standard approach.
I'm using --with-libxml2=DIR in my configure.in, but what I'm not clear on
how to deal with non-standard locations that are not $DIR/include and $DIR/lib
For example, to optionally install libxml2:
AC_ARG_WITH(libxml2,
[ --with-libxml2[=DIR] Build with libxml2 parsers. Specify optional
path],[
if test "$withval" == "yes"; then
LIBXML2_OBJS="parser.o"
LIBXML2_LIB="-lxml2"
LIBXML2_CFLAGS="-DLIBXML2"
elif test "$withval" != "no"; then
LIBXML2_OBJS="parser.o"
LIBXML2_LIB="-R$withval/lib -L$withval/lib -lxml2"
LIBXML2_CFLAGS="-I$withval/include -DLIBXML2"
fi
])
AC_SUBST(LIBXML2_OBJS)
AC_SUBST(LIBXML2_LIB)
AC_SUBST(LIBXML2_CFLAGS)
Say the non-standard locations (which are the build directories) are
$HOME/libxml2-2.4.5/include
$HOME/libxml2-2.4.5/.libs
What instructions should I give in the INSTALL docs?
LDFLAGS="-R$HOME/libxml2-2.4.5/.libs -L$HOME/libxml2-2.4.5/.libs" \
./configure --with-libxml2=$HOME/libxml2-2.4.5
Or LD_RUN_PATH?
Thanks,
