configure: check whether shell is capable of parameter substring processing

2012-07-25T11:17:24Z

'configure' script uses parameter substring extensively. It is Posix shell feature. Original Bourne shell does not have such features. Some systems still ships such shells as /bin/sh (for compatibility reasons -- shell scripts written on those platforms are expected to work on 1990's systems). Just testing whether parameter substring processing works will make the shell exit due to syntax error if it is not compatible. Therefore the test is executed in a subshell -- subshell exits with nonzero value when the operation in question fails. As 'if ! ...' does not work in Bourne shell, Short-circuiting construct '||' is used to print information message and exit when expected.

config: add quoting to fix IFS bug

Without proper quoting the DEFAULT_IFS was getting set incorrectly, which was causing problems with the storage of some variables later in the script. Quoting fixes the problem.

configure: add help note about gmime version

configure: change gmime version in help message to 2.6

2012-04-05T11:01:32Z

Since GMime 2.6 is now the stable version upstream, and probably the most tested by notmuch developers, it makes sense to suggest that to users to install.

configure: print info about required gmime 2.4 or 2.6 versions

2012-04-05T10:53:04Z

In case required gmime (2.4 or 2.6) version if not found print information about both alternatives (and currently minimal 2.6 version that is needed).

configure: add empty line after each missing component message

2012-04-05T10:50:51Z

Currently whenever message about missing GMime, Glib or talloc is printed the message is 2 lines, component info and its http location in next line. In the future the amount of lines will vary. To ease reading in these cases newline is added after each message.

Allow selecting which version of gmime is used to build notmuch.

2012-03-20T11:11:27Z

This allows for testing against both versions of gmime on a single machine, without having to mess with pkg-config paths. This is rework of Tom Prince's patch submitted in id:"1331402091-15663-1-git-send-email-tom.prince@ualberta.net"

configure: store $IFS to $DEFAULT_IFS readonly variable

2012-03-20T11:10:57Z

In the future, IFS value needs to be changed in a few places in configure -- and then restored. Store the original value to $DEFAULT_IFS for easy restoration.

Do not try to parse the options for --build and --host arguments

2012-03-20T11:10:57Z

Formerly the code assumed the arguments to be triples and threw an error if this was not the case. But those arguments are only there for compatibility with autotools and are not used within the build system, so just dropping the code parsing these values makes the build system more robust.
