makefile: fix prosody.version target
POSIX is quite explicit regarding the precedence of AND-OR lists [0]:
> The operators "&&" and "||" shall have equal precedence and shall be
> evaluated with left associativity. For example, both of the following
> commands write solely `bar` to standard output:
> false && echo foo || echo bar
> true || echo foo && echo bar
Given that, `prosody.version` target behaves as
((((((test -f prosody.release && cp ...) ||
test -f ...) &&
sed ...) ||
test -f ...) &&
hexdump ...) ||
echo unknown > $@)
In the case of release tarballs, `prosody.release` does exist, so the
first AND pair is executed. Given that it's successful, then the first
`test -f` in the OR pair is ignored, and instead the `sed` in the AND
pair is executed. `sed` success, as `.hg_archival.txt` exists, making
the second `test -f` in the OR pair ignored, and `hexdump` in the AND
pair is executed. Now, given that `.hg` doesn't exist, it fails, so the
last `echo` is run, overwriting `prosody.version` with `unknown`.
This can be worked around placing `()` around the AND pairs. Decided to use
conditionals instead, as I think they better communicate the intention
of the block.

(This file was created from https://prosody.im/doc/installing_from_source on 2013-03-31) ====== Installing from source ====== ==== Dependencies ==== There are a couple of libraries which Prosody needs installed before you can build it. These are: * lua5.1: The Lua 5.1 interpreter * liblua5.1: Lua 5.1 library * libssl 0.9.8: OpenSSL * libidn11: GNU libidn library, version 1.1 These can be installed on Debian/Ubuntu with the packages: lua5.1 liblua5.1-dev libidn11-dev libssl-dev On Mandriva try: urpmi lua liblua-devel libidn-devel libopenssl-devel On other systems... good luck, but please let me know of the best way of getting the dependencies for your system and I can add it here. ==== configure ==== The first step of building is to run the configure script. This creates a file called 'config.unix' which is used by the next step to control aspects of the build process. All options to configure can be seen by running ./configure --help. Sometimes you won't need to pass any parameters to configure, but on most systems you shall. To make this a little easier, there are a few presets which configure accepts. You can load a preset using: ./configure --ostype=PRESET Where PRESET can currently be one of: 'debian', 'macosx' or (in 0.8 and later) 'freebsd' ==== make ==== Once you have run configure successfully, then you can simply run: make Simple? :-) If you do happen to have problems at this stage, it is most likely due to the build process not finding the dependencies. Ensure you have them installed, and in the standard library paths for your system. For more help, just ask ;-) ==== install ==== At this stage you should be able to run Prosody simply with: ./prosody There is no problem with this, it is actually the easiest way to do development, as it doesn't spread parts around your system, and you can keep multiple versions around in their own directories without conflict. Should you wish to install it system-wide however, simply run: sudo make install ...it will install into /usr/local/ by default. To change this you can pass to the initial ./configure using the 'prefix' option, or edit config.unix directly. If the new path doesn't require root permission to write to, you also won't need (or want) to use 'sudo' in front of the 'make install'. Have fun, and see you on Jabber!
