Hi.
I have been searching for an alternative PBX to asterisk (which has not
been all that stable) to run on Dragonfly BSD. I spent a fair amount of
time a couple months ago trying to compile freeswitch without success.
I have since tried Yate, but it consumes 85-95% of the cpu when idle
(not processing any calls).
I am considering revisiting freeswitch. I have included below my notes
of all the various problems I encountered before, which ones I resolved
and how, up to the point where I left off. I am in hopes of getting
feedback on whether any of the issues have been fixed or are planned to
be fixed and/or suggestions on getting it working. Also, perhaps these
notes on my experiences will be helpful for the developers to improve
freeswitch.
Keep in mind that Dragonfly is a branch from Freebsd and stays fairly
compatible. I am able to compile most software, that is ported to
FreeBSD, with few problems.
Here are my notes
=================
To compile on dragonfly BSD 1.10.1-RELEASE
==========================================
I had to add -D__FreeBSD__ to CPPFLAGS
ln sh to bash or zsh
because I got "unexpected operator" errors from "test" during configure
with the bsd shell.
ln make to gmake
Their scripts were calling make even though I ran the build
using gmake.
Must have apr-0.9.16.2.0.61 and apr-util-0.9.16.2.0.61 installed
apr-0.xxx has headers, which freeswitch is including, that apr-1.xxx
does not have.
I sym-linked the apr-util libs from apr-util-1.2.8nb1 because
apr-util-0.9.16.2.0.61 was not available as a binary package.
The freeswitch-1.0.3.tar.gz release did not have bootstrap.sh, which is
required for building from the svn repository.
Somebody on the #freeswitch IRC suggested I get it from the subversion
repository and run the bootstrap script. bootstrap.sh is not in the
release.

I posted on the freeswitch mailing list asking about the compilation errors
Got no responses.
This first set of apr_... warnings turned out to clearly be from not having the
correct apr-util package installed, I should have gotten a response on the list
about it, considering it is a clear dependency that they do not directly
specify on the web site or the source docs. apr-util is a dependency of
subversion. They list SVN as a dependency of freeswitch, which is the utility
in the subversion package, not the package name. svn should not be
a dependency to build from a release archive that is not retrieved from the svn
repository.
As it turns out, it had to be apr-util version 0.9.15. See notes below.
==========================================

I tried the freeswitch-snapshot.tar.gz from the freeswitch site, which is
a 03/30/2009 snapshot from the svn trunk.
*concern*
It was nearly twice as big as the release for some reason.
27016871 Mar 28 13:08 freeswitch-1.0.3.tar.gz
52854882 Mar 31 18:25 freeswitch-snapshot.tar.gz
Running bootstrap.sh produced a bunch of these errors from automake:
Use of uninitialized value in exists at /usr/pkg/bin/automake line 4823, <GEN0> line 1.

Going back to the 1.0.3 release.
I was getting a a bunch of apr_... warnings like
Compiling src/switch_apr.c ...
src/switch_apr.c: In function `switch_thread_self':
src/switch_apr.c:74: warning: implicit declaration of function `apr_os_thread_current'
src/switch_apr.c:74: warning: return makes pointer from integer without a cast
...
Then
gmake[3]: *** [libfreeswitch_la-switch_apr.lo] Error 1
I finally got past that by installing apr-0.9.16.2.0.61 and apr-util-0.9.15.
I compiled apr-util-0.9.15 myself because it was not available as a binary
package.
Source files are including headers from apr-util-0.9.15 that do not exist in the
binary package, apr-util-1.2.8nb1.tgz.
I also got past the "Cannot guess build type" error during configure by adding
"--build=i386" instead of having to use the uname wrapper to fake FreeBSD.
==========================================
New error: (This one is not the fault of freeswitch)
Compiling src/switch_core.c ...
src/switch_core.c: In function `switch_core_setrlimits':
src/switch_core.c:795: error: `RLIMIT_AS' undeclared (first use in this function)
Turns out RLIMIT_AS is defined in /usr/include/sys/resource.h on some other
systems including FreeBSD but not Dragonfly.
It is used in the source like this
#if !defined(__OpenBSD__) && !defined(__NetBSD__)
setrlimit(RLIMIT_AS, &rlp);
It is defined in resource.h in FreeBSD like this
#define RLIMIT_AS RLIMIT_VMEM /* standard name for RLIMIT_VMEM */
I created a patch for src/switch_core.c which fixed this error.
Since then, I discussed this on the Dragonfly BSD mailing list and it is
apparently going to be fixed on a future release of Dragonfly now that
they are aware of it.
==========================================
New error:
Tons of warnings like
warning: return makes pointer from integer without a cast
(this needs cleaned up)
Then error'd with
gmake[8]: *** No rule to make target `iptsec/libiptsec.la', needed by `libsofia-sip-ua.la'. Stop.
I cd'd to libs/sofia-sip/libsofia-sip-ua/su
and ran make there. It completed successfully in spite of the same warnings.
Then ran make again form the top.
Got further until
==========================================
New error:
making all mod_spidermonkey
cd config; gmake -j1 export
cd pr; gmake -j1 export
cd include; gmake export
cd md; gmake export
../../../config/./nsinstall: cannot make symbolic link /u1/falcon/ports/freeswitch-1.0.3/work/freeswitch-1.0.3/libs/js/nsprpub/dist/include/nspr/.: File exists
Why would it be trying to make a sym-link of '.' ??
==========================================
Giving up for now.
