The PKGBUILD of syslog-ng 3.0.1-6 from ABS fails with the following message:

/usr/bin/ld: cannot find -lcap
collect2: ld returned 1 exit status

I have verified that libcap 2.16-3 is installed on my system:

$ locate libcap
/lib/libcap.so
/lib/libcap.so.2
/lib/libcap.so.2.16
This task depends upon

It fails because tries to compile it as static (and libcap as static don't exists), (this dependecy is autodetected)

In official arch build don't fails, because developers build under chroot env.

Also syslog-ng, compiles other libs as static (because is configured in "mixed mode"), this is a bad idea, but decreses the dependencies.

@Jason: libcap need to include the static version but, this patch will link to libcap as shared. I don't know what are the objetives of the packager of syslog-ng, I supose that are in reduce the number of dyn deps, this is because also glib2 is linked as static like others libs. Personally i prefer to do all shared. This bahaviour can be configured without patch.

Here is the patch (if maintainers accept to build as shared [#1])

* Update the latest syslog-ng 3.0.2
* Fixed the license
* Removed uid.patch, not ncessary anymore, already fixed in 3.0.2
* Fixed missing \ in configure options so the rest option was discarded.
* Added two linked flags to reduce the numbers of unused direct depends.
* Shared mode is now default in 3.0.2

Resulting binary is 238K vs 2M

oops add openssl to depends array i missed that!

Updated patch against latest version 3.0.3 for current SVN trunk.

@Other assignees: any objections to me pushing this with djgera's PKGBUILD. Building with shared libraries does add glib2 as a dep (among other packages of less concern), which is ~10MB installed. But I think shared is better and glib2 is on 99.43% of systems according to pkgstats so I am happy with this.

No problem.

Just remember to move libcap to [core]
