I am having trouble finding some macro or something for my
configure.ac to for zlib support. I found this so far:
http://ac-archive.sourceforge.net/ac-archive/check_zlib.html
But this simply adds the option AC_ARG_WITH so zlib is optional but my
work needs zlib now so its a little annoying to always have to
./configure --with-zlib...
Not sure if there is a cool trick to simply always turn it on but i am
sure there is a better setup for this out there since zlib is so
widely used!
I'm not sure I understand why you are looking for something
zlib-specific at all. If you need to check for a library, you can use
AC_CHECK_LIB or one of its sister macros, and you can use
AC_CHECK_HEADERS for header files. Your users can pass CPPFLAGS=-I...
and LDFLAGS=-L... to configure if the files are to be found in
nonstandard locations. gnulib also has the module havelib to make this
a bit more generic and help with run paths.
Hope that helps. Otherwise, please be more specific in what doesn't
work for you (show code, specify needed semantics, etc).
