I just committed a change that might fix this issue. Please try again from the git
repository.

Good to hear someone trying to build for OSX :)

Hi,

Nice to know you care ;)

Apparently the commit fixed the issue...
However I'm having a new one:

gcc `pkg-config --libs purple` `pkg-config --libs gobject-2.0` directconn.o error.o
msn.o nexus.o notification.o object.o page.o session.o state.o switchboard.o sync.o
pecan_log.o pecan_util.o cmd/cmdproc.o cmd/command.o cmd/history.o cmd/msg.o
cmd/table.o cmd/transaction.o ab/pecan_group.o ab/pecan_contact.o
ab/pecan_contactlist.o io/pecan_stream.o io/pecan_node.o io/pecan_cmd_server.o
io/pecan_http_server.o cvr/slp.o cvr/slpcall.o cvr/slplink.o cvr/slpmsg.o
cvr/slpsession.o fix_purple.o -shared -o libmsn-pecan.so
Undefined symbols:
  "_main", referenced from:
      start in crt1.10.5.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
make: *** [libmsn-pecan.so] Error 1


One bit of info: I'm using macports for most of the libs so I may be missing something...

Which reminds me that it would be useful to put the build dependencies in the Wiki.
From what I can understand it's Glib and Pidgin/libpurple.

Can you try to build the official MSN plugin and paste the commands executed by make?

Here it is.

I would like to see the output of the libtool command without the silent option. From
your log this is the last command executed:

libtool --silent --tag=CC --mode=link gcc -g -g -O2 -module -avoid-version -o
libmsn.la -rpath /usr/local/lib/purple-2 cmdproc.lo command.lo contact.lo dialog.lo
error.lo group.lo history.lo httpconn.lo msg.lo msn.lo nexus.lo notification.lo
object.lo oim.lo page.lo servconn.lo session.lo slp.lo slpcall.lo slplink.lo
slpmsg.lo slpsession.lo soap.lo soap2.lo state.lo switchboard.lo sync.lo table.lo
transaction.lo user.lo userlist.lo msnutils.lo -L/opt/local/lib -lgobject-2.0
-lgmodule-2.0 -lgthread-2.0 -lglib-2.0 -lintl -liconv -lutil -lpthread -lresolv 
-framework IOKit -framework CoreFoundation

Just remove the --silent.

I've just found the problem, mac os x does NOT support -shared option in gcc4, I don't know the solution 
yet, but I'm working on it, here is the output:

cc `pkg-config --libs purple` `pkg-config --libs gobject-2.0` directconn.o error.o msn.o nexus.o 
notification.o object.o page.o session.o state.o switchboard.o sync.o pecan_log.o pecan_util.o 
cmd/cmdproc.o cmd/command.o cmd/history.o cmd/msg.o cmd/table.o cmd/transaction.o 
ab/pecan_group.o ab/pecan_contact.o ab/pecan_contactlist.o io/pecan_stream.o io/pecan_node.o 
io/pecan_cmd_server.o io/pecan_http_server.o cvr/slp.o cvr/slpcall.o cvr/slplink.o cvr/slpmsg.o 
cvr/slpsession.o fix_purple.o -shared -o libmsn-pecan.so

This is the man file of gcc in mac os x leopard
  -shared
           Produce a shared object which can then be linked with other objects to
           form an executable.  Not all systems support this option.  For
           predictable results, you must also specify the same set of options that
           were used to generate code (-fpic, -fPIC, or model suboptions) when you
           specify this option.[1]

           This option is not supported on Mac OS X.

***FIXED***
The problem is as I suspected, if you change the libmsn-pecan.so section to the following, you will be happy,
I'm modifying the Makefile to detect darwin, and issue the correct flag, but until the next release, change it by 
hand, just want to state that this is my first contribution to the project, I'm really happy :).

libmsn-pecan.so: $(objects)
	$(CC) -dynamiclib $(PURPLE_LIBS) $(GOBJECT_LIBS) $+ -o $@

I can not confirm the the fix. I tried to compile it under 10.5.2 xcode 3 , pidgin
2.4.1. I added my changed Makefile and the output of make. I hope this info is usefull.

I'm in work now, so I can't do much, but I've made a small research on the matter, 
I'm using mac os 10.5.2, cant check my gcc version now, but this bug appears in 
other projects as well, seems like is something to do with inline functions, here is 
the thread http://lists.apple.com/archives/unix-porting/2007/Oct/msg00038.html 

It compiled fine for me after my fix, I'm using pidgin 2.3.1 (macports one) and mac 
os x 10.5.2 with the latest update.

So I believe the bug is either between pidgin 2.3.1-2.4.1 or in older versions of 
gcc.

kooyman, can you please make sure yo have the lates apple updates, and make a post 
with your gcc version ?

I'll be looking further into this matter tonight.

Well into further research ( I should be working right now ) I've  discovered that 
this is a major bug in inline functions in mac os x 10.5.2.

There is a workaround(inline patch) in the glib ports in macports, don't know if you 
are using macports kooyman, but the problem is definately in glib and friends, I am 
almost sure that if you upgrade your glib in macports everything should work fine, 
If you have the time, please issue a major upgrade to your macports, also because if 
not, you will see this problem in other builds as well.

I've installed macports few minutes before compiling msn-pecan, so I believe my glib 
has the inline patch and so I didn't get this error.

This thread of macports explains everything:
http://trac.macports.org/projects/macports/ticket/13006

Note that the resolution is "works for some", but I do believe that if the upgrade 
of macports does not solve the matter, a major reinstall of macports should do.

Great job Christiano!

I was traveling but now I'm back. I will commit your patch and hopefully that will be
all that's needed for this issue.

Please try with the new repository, the commit is there.
