While the actual build failures have been fixed independently by
d1d3ac9 "build: reorder libraries to address linker error", libzebra
still does not reference libcap. This will lead to more build failures
if someone else tries to use libzebra and doesn't add libcap.
Let's just add libcap here and be done with it.
I've not added libcap to the _DEPENDENCIES variable above since libcap
is a system library. Actually, the whole _DEPENDENCIES thing is rather
fishy; automake automatically sets _DEPENDENCIES from _LIBADD. For the
sake of not breaking stuff that works (especially since most autotools
stuff is arcane magic), I'm leaving it alone...

There are systems with no /bin/true - it might have different path
(/usr/bin/true) or even a shell builtin.

automake file lists haven't quite kept up with recent changes, time to
fix them up so the dist tarball actually works...

If enabled with --with-pkg-gitversion on ./configure, this will append
git version strings and branch information at the following places:
- overall version number: 0.99.21-g0123456
- login motd and show version: tag information + git id + branches
Sample output:
Hello, this is Quagga (version 0.99.21-g14b49ad-dirty).

--enable-snmp will enable AgentX support in Quagga. SMUX is still here
and can be enabled with --enable-snmp=smux. AgentX support can be
enabled with "agentx" in configuration file. As for SMUX, this command
is not understood by vtysh. It can be disabled with "no agentx",
though there is no real use of this since this command cannot be used
with vtysh.
If "agentx" and "no agentx" command were added to vtysh, it would not
be possible to disable agentx support after enabling it because
NetSNMP does not expose the appropriate methods for this.
The internals of AgentX are hidden by NetSNMP. Therefore, we don't
have a file descriptor to add to the threading system. We do not have
the timers to set either. Therefore, the event loop is modified to
make use of snmp_select_info() from NetSNMP.
Traps are not supported yet.

lib/snmp.c gets OID related helper functions that can be used with
another SNMP interface. smux.h is cleaned of SMUX specific bits to
only expose functions that may be used by an alternative
implementation. We also do not redefine functions already present in
NetSNMP. Just use the appropriate headers.
|
|
The correct method to link to NetSNMP is to use net-snmp-config (which
is like pkg-config). Explicit link to libcrypto is also dropped
(NetSNMP libs are linked to libcrypto, no need to link Quagga to
it). Moreover, @SNMP_INCLUDES@ is dropped because useless. Due to a
bug in configure.ac, it was properly populated.

Some .h files in lib/ are autogenerated. The search path should
include the build directory and the source directory. They usually
match but sometimes, they may be different. For example:
$ mkdir build
$ cd build
$ ../configure
$ make
|
|
this replaces most occurences of routing protocol lists by preprocessor
defines from route_types.h. the latter is autogenerated from
route_types.txt by a perl script (previously awk). adding a routing
protocol now is mostly a matter of changing route_types.txt and log.c.
Conflicts:
lib/route_types.awk

Stephen:
A recent change breaks build Quagga on Debian Lenny with amd64 (but not
i386). Not sure whether this is cause by ld, gcc, or libtool; but
whatever it just won't work for a large number of users.
Mathias:
I would guess it's a problem of libtool because it adds "-fPIC -DPIC" to
the compiler flags but doesn't remove -fPIE. That wouldn't be a problem
if the compiler would ignore the -fPIE in favor to the latter -fPIC, but
obviously it does not. [...] Those objects were actually compiled with
-fPIC but also -fPIE which seems to confuse gcc.
|
|
Because the final executables are built as position independent
executables (PIE) -- when configure has detected compiler supported for
PIE -- the objects in the library archive must be built in that way,
too. Otherwise the runtime linker has to do unneccesary relocation for
each start of the program. Even worse, the programs won't even be able
to start on a (hardened) kernel that doesn't allow those relocations to
happen by preventing making the .text segment writable (PaX's MPROTECT
feature comes to mind). The attached patch fixes this issue by adding
the appropriate flags to the Makefile.am.

* route_types.txt: New file, table of ZEBRA_ROUTE definitions.
* route_types.awk: New script, to parse previous and generate
(for now) redistribute string defines.
* Makefile.am: build route_types.h using previous two, ala
memtypes.h, include the script and table file in EXTRA_DIST.
* command.h: pull in route_types.h, add a REDIST_STR define.
|
|
2006-03-16 Paul Jakma <paul.jakma@sun.com>
* Makefile.am: Fix -version-info argument.
|
|
* zebra.h: BSD BYTE_ORDER define isn't available everywhere,
define if needs be.
* checksum.h: new file. checksum.c exports in_cksum, provide
a header for it.
* checksum.c: (in_cksum) callers shouldn't have to know it uses
a u_short internally, change to void *.
* Makefile.am: Add checksum.h
* command.h: remove bogus trailling slash.
* md5.c: (general) Update it for the twentieth century. ANSI
declarations are widely supported now.. Don't include system
headers, only include zebra.h. Use POSIX types (the
alternative is to define u_int64_t in a portable way - rest
of Quagga needs same cleanup).
Make endian-conditional code be compiler conditional rather
than preprocessor conditional, so that breakage gets noticed
quicker.
* md5.h: POSIX types. Get rid of the odd __P() non-ANSI capable
compiler compatibility hack.
|
|
* lib/md5-gnu.h: removed
* lib/md5.h: replaces md5-gnu.h
* lib/Makefile.am: use correct md5.h
* lib/md5.c: import from WIDE

background threads.
* command.c: install the 'show workqueues' command
* memtypes.c: Add work queue mtypes, and a rib-queue type for
a zebra rib work queue.
* memtypes.h: Updated to match memtypes.c
* Makefile.am: Add new workqueue files to build.

to HACKING (which I added..)
|
|
* Makefile.am: Refer to source files via srcdir variable, fix
out-of-tree build breakage.

var.
* memtypes.h: New file, auto-generated, checked in for convenience.
|
|
* memtypes.c: The new, unified location for memory type definitions.
The memtype enum and declarations for memory_lists are built from
this automatically and put into memtypes.h.
* memtypes.awk: New script to generate memtypes.h from memtypes.c
* memory.h: Finally, the enum can banished!
* memory.c: Finally, the seperate mtype memory_list definitions can
be banished!
(log_memstats) Increase width of fields
(show_memory_zebra_cmd) display zebra specific memory types.
Increase width of fields.
* Makefile.am: Add memtypes.{c,h}, add BUILT_SOURCES for memtypes.h
Add a rule to build memtypes.h using memtypes.awk.
Add memtypes.awk to EXTRA_DIST.

must be after lib/ includes in some systems. Introduce SNMP_INCLUDES
for that.
|
|
* debug.[ch]: Remove unused files.
* Makefile.am: Remove references to debug.c and debug.h
* ospf_main.c: Remove #include "debug.h" (was not being used, and
lib/debug.h has now been deleted).

|
|
|
|
added to strings and a lot of int -> unsigned int changes.

* */Makefile.am: Use ../dir/libfoo.la, rather than "-L../dir
-lfoo", to avoid linking against installed libraries from a
previous version.
* {lib,ospfd,ospfclient}/Makefile.am: explicitly define the shared
library version number to be 0.0
* configure.ac: remove spurious , so extract.pl is chmod'd +x.
* HACKING: explain shared library versioning rules
|
|
* jhash.{c,h}: New files. Bob Jenkins' public domain hashing
function, as implemented in linux kernel by David Miller.

libzebra and libospfapiclient are now built shared, and linked shared
with the daemons. This reduces the memory needed when running
multiple daemons; each daemon is at least 150k smaller. Static
libraries are still built, and libtool should use them on platforms
which don't have shared libaries. As with autoconf, the user of a
distribution does not need libtool; one just needs that to build from
CVS.
libospf.a is still a non-shared library, and still installed, not
because that makese sense, but because I don't understand why it is
the way it is now.
Note that the tree was tagged 'libtool-before' just before this commit.

* tests/test-sig.c: New file, regression test for sigevents.
* lib/Makefile.am: add sigevent.{c,h}
* (isis|rip|ripng|ospf|ospf6|bgp)d/\1_main.c: modify for sigevents.
* zebra/main.c: ditto.
|
|
Use pkginclude_HEADERS rather than include_HEADERS to place includes
in ${prefix}/include/quaggainstead of polluting ${prefix}/include.
|
|
* configure.ac: Check for fcntl()
* {bgpd,ospf,ospf6d,ripd,ripngd}/Makefile.am: Install conf file via
regular automake means, not magic install incantations, see
bug #38.
* lib/Makefile.am: install the headers, needed to link libzebra.a
(and hence libospf.a, OSPF-API, etc.)
|
|
* lib/Makefile.am: Do not use a lib (libcap) as a dependency
* zebra/Makefile.am: Link in libcap
|
|
* Merge of zebra privileges
|

same idea as in lib/distribute.c to allow extract.pl to pick up commands
for vtysh.
|

http://hasso.linux.ee/zebra/ht-ifrmap-14042003.patch
Allows to extract.pl to pickup "route-map xxx in/out dev" commands for vtysh
(ripngd). As lib/if_rmap.[c|h] are used in ripngd only, I moved them to the
ripngd/ directory.
|
|
--------------------------------
I've attached a small patch for zebra-pj, which adds the installation of
libospf.a libzebra.a, libospfapi.a and the needed headers for ospfapi
clients. the headers get installed to /usr/include/ospfd/* and
/usr/include/ospfapi.
