Sorry to answer your question with a question..
Have you tried waf? http://code.google.com/p/waf/
Their "projects using waf" page lists the JACK audio connection
kit as one of the projects, so perhaps there is some good
reasons as to why JACK went with waf instead of autotools.
I have used waf myself in the past and found it extremely
pleasant. Autotools is very powerful but it is a bit higher in
the arcane-wizard-knowledge category.
The waf project has a number of examples in their source tree
and on their webpage. You can also browse the jack source tree
to get a feel for it. Look for the waf 'wscript' files.
Their README describes how to build jack using waf.

Have fun,

FWIW, Autotools is a pretty good thing, but it's tricky to learn... and not a
fun process. (Well, M4 macros are *kind* of fun... but that's about it.)
There are lots of alternatives, including:
* waf -- If you know the Python programming language,
this may be a good choice. I've heard good things
about waf.
* CMake -- This is what the KDE project now uses.
* qmake -- If you're doing a Qt project, this is
a pretty good option.
* scons -- Like waf, it's based on Python. A lot
of people like it, and several audio projects
(like Ardour and Hydrogen) use it. However, I don't
personally recommend this system.

First of all, do you have the file lv2_uri_map.h on your system? What is the
path to the file?
Suppose it is '/usr/include/lv2/lv2_uri_map.h' In that case, you have a couple
options:
1. Change lv2plugin.hpp so that:
#include <lv2_uri_map.h>
becomes:
#include <lv2/lv2_uri_map.h>
2. If using gcc or g++, make sure that the compiler
is run with -I/usr/include/lv2. I.e.:
g++ -c -g -O2 -I/usr/include/lv2 -o foo.o foo.cpp
With autoconf, this is done by adding the value to CPPFLAGS (or CXXFLAGS if you
only want it to affect C++ programs). So, after you detect where the directory
with the headers is... you add it like this:
CPPFLAGS="$CPPFLAGS -I/usr/include/lv2"

Exactly, you have to somehow inform your gcc of where
the headers are
via the -I option.
One problem: the LV2 extension headers aren't supposed to be installed
system-wide, they're usually distributed with individual software
packages (Ingen, Calf, Ardour... you name it).

g++ can't find your headers (e.g. lv2_uri_map.h, lv2_saverestore.h, etc.).
Where are they installed? It would help if we could see what the g++ command
looked like when `make` ran it. That way we can see which -I and -D flags were set.
These lines are supposed to set up all your flags so that all the headers and
libraries are found:
PKG_CHECK_MODULES(LV2CORE, lv2core, ,[AC_MSG_ERROR(Can't find liblv2core)])
PKG_CHECK_MODULES(LV2_PLUGIN, lv2-plugin, ,[AC_MSG_ERROR(Can't find
liblv2-plugin)])
It appears that something with the lv2-plugin line is failing.

/bin/sh ../libtool --tag=CXX --mode=compile g++ -DHAVE_CONFIG_H -I.
-I.. -g -O2 -MT and.lo -MD -MP -MF .deps/and.Tpo -c -o and.lo and.cpp

-MP -MF .deps/and.Tpo -c and.cpp -fPIC -DPIC -o .libs/and.o
Now I see that it's obvious that -I and -D flags seem wrong but I got no
clue why?
Thanks

Don't set CPPFLAGS or anything like it in Makefile.am. These are set in
confingure.ac. Also, there's rules about which ones the user sets and which one
the build system sets. E.g. I think CFLAGS is reserved for the build system,
but CPPFLAGS reserved for the user.

Not so much user-reserved vs. build system-reserved:
CPPFLAGS are for the C preprocessor, so -Ddefines and -I includepaths would
be preprocessor flags. CFLAGS would be for C compiler flags, e.g.
optimization or architecure flags.

Right and the one you can set from Makefile.am are called
AM_CFLAGS and AM_CPPFLAGS.

Hi,
thanks for your help but I'm already with waf now. Builds fine although
I haven't tested the binaries. Was wondering why I mustn't tell waf
about any libraries.
It's very easy and fast to learn although I didn't know anything about
python I'm not even sure what a preprocessor does.
