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 ...

We don't expect the GNU'ish behaviour of of malloc() and realloc() and never
implemented the replacement functions rpl_malloc()/rpl_realloc() -- so these
test result in linking failues on systems that don't have a GNU'ish malloc()
and realloc() even though we don't require it!
Introduced by commit 47ad9afc.

Use the AC_SEARCH_LIBS macro to test for "sometimes but not always"
required libraries, not AC_CHECK_LIB.

Don't use AC_C_PROTOTYPES, AM_C_PROTOTYPES is already used.
|
|
Update checks for required and optional header files, data types,
and functions.
|
|
And use newer features such as bug reporting address and project URL.
|
|
|
|
AM_CONFIG_HEADER is marked obsolete and will be removed in Automake 1.13.

Thanks to Christoph Biedl!

This fixes commit 8e193df ...

|
This fixes building ngIRCd on Debian GNU/Linux 1.3 "Bo" :-)
|
|
If gai_strerror() isn't available, use a macro that simply returns
a static error message (regardless of the real error code).
For example, GNU libc 2.0.7 doesn't implement gai_strerror().

See contrib/Anope/README and doc/Services.txt for more details
and installation instructions!

Don't use isdigit() function any more, because it only checks the
first character of the variable value and because it doesn't know
about the minus sign which is required e.g. for "Group = -1".
|

|
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!

This is required for enabling ansi2knr on systems that don't have an
ANSI C compiler installed (e.g. on A/UX with Apple standard C compiler).

Allows to defer/queue signal processing for execution on the next
event dispatch call, i.e. we can perform any signal action in
normal, non-signal context.
Example uses:
- Reload everything on HUP without writing a global "SIGHUP_received"
variable
- Dump status of internal Lists on SIGUSR1, etc.

Tested on OpenBSD 4.7, OpenBSD 4.1, FreeBSD 8, Linux and Mac OS X.
Thanks to rck <dev.rck@gmail.com> for reporting and testing!

This reverts commit b3a6c33da0b12ba74dc395979b677813d4bc2c0f.
apparently not all gcc versions support this 8-(
|
|
from bugzilla #105:
"ngircd-16 works great under openbsd4.7/i386, but it segfaults on
openbsd4.7/amd64."
Caused by missing function prototypes and the resulting truncation of
pointer to int.
Lets try to catch these bugs during compilation instead of SIGSEGV.
|
|
|
|
|
|
This solves warning messages of autoconf on e.g. FreeBSD 8:
configure: WARNING: netinet/ip.h: present but cannot be compiled
configure: WARNING: netinet/ip.h: check for missing prerequisite headers?

dpkg-shlibdeps: warning: dependency on libnsl.so.1 [..]
(they use none of its symbols).
As shown via commit 2b14234abc252383679bae2d23861b773dc9713e
(dpkg-shlibdeps: warning: dependency on libnsl.so.1) and the
following revert of that commit, we cannot simply drop
the AC_CHECK_LIB(nsl). Although -lnsl is indeed unneeded
when glibc is used, some platforms (e.g. Solaris) need it.
Use AC_SEARCH_LIBS instead to only link when the library exports
a particular symbol.

Test for sockaddr_in.sin_len and initialize it to the correct value
which some systems (notably Mac OS X) require.
Note: this code path is only relevant when not using getaddrinfo().
|
|
Both getaddrinfo() and getnameinfo() are now used always when available, and
not only when compiling ngIRCd with support for IPv6.
This not only enables ngIRCd to handle multiple addresses per hostname when
compiled without support for IPv6, but fixes binding ngIRCd to IP addresses
on Mac OS X (and probably other BSD-based systems) as well: these systems
require that sockaddr_in is zeroed out and sockaddr_in.sin_len is set to
sizeof(sockaddr_in) like that:
src/ipaddr/ng_ipaddr.c, line 54:
assert(ip_str);
+ memset(addr, 0, sizeof *addr);
+ addr->sin4.sin_len = sizeof(addr->sin4);
addr->sin4.sin_family = AF_INET;
But this would break all the systems not using sockaddr_in.sin_len, for
example Linux -- so we assume that all these systems provide getaddrinfo()
and use that for now.

This patch fixes --with-openssl and --with-gnutls and enables both to
accept path names, so that you can use "./configure --with-XXX=/path".
All the other --with-XXX parameters support this already.
|
|
Starting with GNU automake 1.11 "AM_SILENT_RULES([yes])" is available to
make the build process less verbose ("Linux 2.6 style") which helps to
spot warning and error messages.
So we use it if it is available.

This adds the required code to enable ssl/tls support
during compile and run time, respectively.
