Re: [Monotone-devel] library-build progress report and request for help with botan

Hi,

I've finally got around playing with that branch again. Some remarks below.

+1 for naming it "src".

Trying that setup, I've been puzzled about all the steps needed. I still 
don't get warm with the mixture of the configuration step and the actual 
building step. However, that might just be personal preference. Trying 
to build the whole thing, I've encountered the following problems:

 * I've spent some time to figure out that I needed to run aclocal for 
every subdir. Only later on, I've noticed that there's an autogen.sh 
script which does that for me. However, as INSTALL still recommends 
running aclocal manually, that might entrap other users as well.

 * If pcre's configure script fails after having created pcre/Makefile 
(for example due to missing config.h.in), a subsequent 'make 
pcre/Makefile' won't restart configure for pcre, because the Makefile is 
up-to-date. Maybe simply add more of the files there as dependencies, so 
that make reruns pcre's configure.

 * Botan's 'make install' complains about ownership problems:

install: cannot change ownership of 
`/home/markus/projects/monotone/build.nvm.library-build/libinst/share/doc/Botan-1.7.4/credits.txt': 
Operation not permitted

Do we really need to run 'make install' for these 3rdparty libraries? 
Having top-level 'make' recurse into all of subdirs running 'make 
install' every time seems expensive to me.

After having worked around these issues, I've been able to run 'make' 
and 'make install' in all of the subdirectories (lua, botan, pcre, 
netxx, idna and sqlite).

Jup, even the -stamp targets are working.
