installed version of libt2n.
To build it seperately using a installed version of libt2n:
-autoreconf -i && ./configure && make && make distcheck
+autoreconf && ./configure && make && make distcheck
-if it does not work try something like:
+if it does not work you may have to move the example-codegen out of the libt2n directory and
+pass some options to autoreconf
+I use something like:
tar xzvf libt2n-0.1.tar.gz
mv libt2n-0.1/example-codegen .
cd example-codegen
-# get configure script created and missing autotools stuff
-aclocal && automake -a && autoreconf -i
+# get configure script created and missing autotools helper files installed
+# if you installed libt2n in some non-standard directory you might have to pass
+# -M pathtolibt2n.m4
+autoreconf -f -i
./configure && make && make distcheck
+
+tar xzvf libt2n-0.1.tar.gz && mv libt2n-0.1/example-codegen . && cd example-codegen && autoreconf -f -i -M /tmp/jens-delme/usr/share/aclocal && ./configure && dmake && dmake distcheck
- would be nice to reduce amount of changed files
(codegen output is often the same as the existing files - something similar to ccache
for codegen - but not overwriting output files if they are the same)

+- howto include the part after "# always the same:" in all makefiles (using the codegenerator)
(we now use make's include)
- lib name should be group name + suffix/prefix
-- at the moment make dist from within a clean source will not work
- (this is related to the nodist problem / old automake version)
- the example should not get installed (but still it should show how to build a lib that gets installed :-(
(overwriting install: doesn't work)
+- at the moment make dist from within a clean source will not work
+ (this is related to the nodist problem / old automake version)
+ this is caused by BUILT_SOURCES not working for make dist(check?)
+ and the dependency generation
+
+ distcheck -> dist -> distdir -> DISTFILES
+
+ all -> all-redirect -> all-am -> Makefile -> BUILT_SOURCES => bene
+
+ => how to add dependency on BUILT_SOURCES for dist?
+ the real problem is that make dist should not depend on BUILT_SOURCES
+ unfortunately we can't fix this as long as we use a old automake version
- add (standalone) example using generated client library
(=> depends on installed example)
example consists of: the same client.cpp but provides a configure.in and Makefile.am
