My main job for the last 10 years or so is porting different low level security apps to UNIX platforms. AIX is almost always the "difficult" one. Everything is always implemented differently. I code around the native security databases (/etc/passwd, shadow, /etc/security, TCB, etc) and AIX is always the strange one. I do have to say though that HP-UX has its quirks, although it generally conforms. Linux is easy, cos you can find the code to everything, so you can code round stuff or at least find out how it works. And there are always lots of people that have tried stuff or implemented stuff and its all relatively up-to-date. I have to admit though that Solaris is my favourite...things just seem to work, and if they dont a quick O/S patch usually fixes it. That is until Solaris 10 where, although I love some of the additions, I hate the horrible SMF service stuff, and process contracts that can make life a pain.

Anyhew, on the linker front, that is why I suggested libtool. You *can* make build systems that build generically and you dont need to know this low level stuff.

But thats all my 2c worth...other people have different views on libtool.

redland-config

redland-config(1)					      General Commands Manual						 redland-config(1)

NAME

       redland-config - script to get information about the installed version of Redland

SYNOPSIS

       redland-config [--cflags] [--help] [--libs] [--libtool-libs] [--prefix[=DIR]] [--private-libs] [--version-decimal] [--version]

DESCRIPTION

       redland-config  is  a tool that is used to determine the compile and linker flags that should be used to compile and link programs that use
       the Redland RDF library.

OPTIONS

       redland-config accepts the following options:

       --version
	       Print the currently installed version of redland on the standard output.

       --version-decimal
	       Print the currently installed version of redland as a decimal integer.

       --libs  Print the linker flags that are necessary to link a redland program.  This excludes linker  arguments  used  to	build  the  librdf
	       shared library.

       --libtool-libs
	       Print the flags that are necessary to link a redland program with libtool.

       --private-libs
	       Print the linker flags that are necessary to build the librdf shared library.  This option is not usually needed because the librdf
	       shared library has already been dynamically linked against these libs.

       --cflags
	       Print the compiler flags that are necessary to compile a redland program.

       --prefix=PREFIX
	       If specified, use PREFIX instead of the installation prefix that redland was built with when computing the output for the  --cflags
	       and --libs options. This option must be specified before any --libs or --cflags options.
