Update autogen.sh & INSTALL for pkg-config requirements

autogen.sh: Fix some shellcheck(1) warning messages

autogen.sh, ngindent, platformtest.sh: Fix warnings of "shellcheck" - SC2006: Use $(..) instead of legacy `..`. - SC2015: Note that A && B || C is not if-then-else. C may run when A is true. - SC2086: Double quote to prevent globbing and word splitting. - SC2166: Prefer [ p ] && [ q ] as [ p -a q ] is not well defined.

autogen.sh: Fix parameter quoting

autogen.sh: Check for autoconf/automake wrapper scripts For example OpenBSD uses a "autoconf" and "automake" wrapper script which tells the user to set AUTOCONF_VERSION and AUTOMAKE_VERSION environment variables. This patch enhances autogen.sh to not detect these wrapper scripts as regular autoconf/automake commands but to set the required environment variables after detecting the real "command-X.Y" commands. Tested on OpenBSD 5.1.

autogen.sh: Don't use "egrep -o", use "sed" "egrep -o" isn't portable and not available on OpenBSD, for example. So let's use sed instead to get the automake version. The expression used now is less specific but should work as well ...

autogen.sh: Enforce serial test harness on automake >=1.13

autogen.sh: Reformat messages.

Rename configure.in to configure.ac This fixes automake: warning: autoconf input should be named 'configure.ac', not 'configure.in' when running the autogen.sh script.

Merge branch 'automake-am11-am12' * automake-am11-am12: autogen.sh: detect automake version format a.b.c and a.b configure.ng: don't require GIT tree to detect version string Include .mailmap file in distribution archives Include all build-system files into distribution archives Change build system to support new and old GNU automake

autogen.sh: detect automake version format a.b.c and a.b

Change build system to support new and old GNU automake Starting with GNU automake 1.12, the "de-ANSI-fication support" has been removed, which ngIRCd used to enable building itself on very old systems. Now the problem is, that using automake >= 1.12 isn't working because of the now unsupported M4 macros. Therefore the solution that this patch implements is to dynamically generate the automake input files with our own ./autogen.sh script: configure.ng => configure.in Makefile.ng => Makefile.am This is quite an ugly approach, but it works and enables us to: 1. use current automake >= 1.12 for development and "private builds", 2. still build distribution archives using automake 1.11.x that have "de-ANSI-fication support" enabled in the generated Makefile's. And if you are using Makefile's generated with a automake version newer than 1.11.x (without "de-ANSI-fication support"), the ./configure script warns you not to use this generated build system to generate distribution archives. Drawback of this patch: you MUST use our autogen.sh script, you can't call the autoconf/automake commands directly any more; but autoreconf should still work ...

Merge branch 'autoconf-update' Update GNU autoconf and automake infrastructure. Tested on modern systems as well as Apple A/UX :-) * autoconf-update: AUTOMAKE_OPTIONS: fix ansi2knr option, include path Don't use AC_FUNC_MALLOC and AC_FUNC_REALLOC Make our own targets "silent", if enabled configure.in: use AC_CHECK_{FUNCS|HEADERS}_ONCE Updated config.{guess|sub} to version 2012-08-14 Make autogen.sh more verbose when VERBOSE=1 is set configure.in: use AC_SEARCH_LIBS (not AC_CHECK_LIB) configure.in: use AS_HELP_STRING macro configure.in: use AC_CANONICAL_HOST (not AC_CANONICAL_TARGET) configure.in: inttypes.h is an optional header file Use HAVE_SETSID #define when testing for setsid() Don't include <stdint.h>, it is included by "portab.h" Don't check type.h availability, it is required configure.in: Use AC_CONFIG_FILES macro configure.in: Don't use AC_C_PROTOTYPES configure.in: Update checks for required and optional features configure.in: require autoconf 2.67 and automake 1.11 configure.in: sort some lists (templates, output, ...)

Make autogen.sh more verbose when VERBOSE=1 is set

Generate ngIRCd version number from GIT tag Now the ngIRCd release/version number is deduced from the "current" annotated GIT tag; see "git describe --help" for details. This is the same scheme the Linux kernel uses and gives much more details version numbers for interim releases and inofficial source archives generated using "make dist". Please note: the version number is only updated it the autogen.sh script is run; so after pulling in and pushing out new commits, you should run ./autogen.sh!

Merge autogen.sh changes Merge commit 'alex/master'

autogen.sh: Don't set AUTO{CONF|MAKE}_VERSION and WANT_AUTO{CONF|MAKE} On some systems (for example Gentoo Linux, FreeBSD, and OpenBSD), these variables are used to select which version of GNU automake and autoconf to use, but we shouldn't depend on a specific version -- instead we should use the "system default". So probably it is up to the user to set these variables accordingly to set up some wrapper scripts of his operating system distribution.

autogen.sh: correctly test for and export ACLOCAL variable

Updated preferred automake version to 1.9. Only set preferences if not already defined by some environment variables.

Added AUTOMAKE_VERSION and AUTOCONF_VERSION (for OpenBSD).

Fixed the detection of tools named like "tool-Major.Minor" (used on OpenBSD).

The command to test for the autoconf/automake tools is detected now as well.

Use "which" when available; understand "GO=0"; made "VERBOSE=1" more verbose.

Enhanced autogen.sh script; added "inline" documentation.

Added missing "return 0" ... oops.

Reworked configure system: it should be more compatible to most systems now, and it should even be more flexible and faster :-)

Made setting of WANT_AUTOMAKE more portable.

Translated success message :-)

Added WANT_AUTOMAKE=1.6 to autogen.sh.

- removed needless warning/info message.

- externe portab-Header werden nicht mehr benoetigt/benutzt, dadurch einige Aenderungen an diversen Source-Dateien und Headern. - Dateien enthalten keine CVS-History mehr.

- fuer fehlende Dateien werden nun "nur noch" symbolische Links erzeugt.
