This is a bug in glibtool not setting the correct compat version in
dylibs...
<rdar://problem/6351733> glibtool sets incorrect current/compatibility
version on dylibs
Here's an example from fontconfig (my comments from that above radar):
2008.11.07 11:23 Jeremy Huddleston:
10.5.4 contained fontconfig-2.4.1 (the 1.1 / 3.0.0 version)
10.5.5 contained fontconfig-2.5.0 (the 1.3 / 5.0.0 version)
The 1.1.0 version was kept around because it wasn't nuked by the SU.
A vanilla install of SULeoGaia should not contain the 1.1.0 version.
As far as compatability goes, on the fontconfig website:
"These also apply to 2.5 and 2.6 which are ABI and API compatible with
2.4."
The file is created with libtool using the following in Makefile.am:
libfontconfig_la_LDFLAGS = -version-info @LIBT_VERSION_INFO@
configure.in:
LIBT_VERSION_INFO="$LIBT_CURRENT:$LIBT_REVISION:$LIBT_AGE"
2.5.0 had:
LIBT_CURRENT=4
LIBT_REVISION=0
LIBT_AGE=3
2.4.1 had:
LT_CURRENT=2
LT_REVISION=0
LT_AGE=1
Note:
bump revision when fixing bugs
bump current and age, reset revision to zero when adding APIs
bump current, leave age, reset revision to zero when changing/removing
APIS
So API was added "twice" without changing/removing API.
This looks like a libtool bug. Libtool is using the LIBT_CURRENT as
the dylib compat version ... is should be:
compat version = CURRENT - AGE . 0 . 0
current version = CURRENT - AGE . AGE . REVISION

2008.11.08 14:24 Jeremy Huddleston:
After thinking about this a bit, I realized the situation is not as
dire as I had once thought.
The library name is libfontconfig.1.dylib ... If there was an ABI
breakage bump, the *name* would be libfontconfig.2.dylib ... so we can
actually get away with using compat version = 1.0.0 for all cases...
then just do:
current = CURRENT + 1 . REVISION . 0 (same as what is done now ... my
comment above is wrong)
compat = 1.0.0 (instead of CURRENT + 1 . 0 . 0 which it is now...)
The library name itself takes care of ensuring the ABI compatability

libpixman is a generic library for manipulating pixel regions. A
PixRegion is a set of Y-X banded rectangles that cover the desired
region.

Turns out the CrashLog has a clue. But I'm not sure how to resolve
it:
Dyld Error Message:
Library not loaded: /usr/X11/lib/libpixman-1.0.dylib
Referenced from: /Applications/Utilities/X11.app/Contents/MacOS/X11
Reason: Incompatible library version: X11 requires version 13.0.0
or later, but libpixman-1.0.dylib provides version 12.0.0

Hi,
I just installed 2.3.2_beta3 on my Leopard 10.5.5 MacBook and am
having several problems with our X11 based application now.
First, I tried to install X11-2.3.1.pkg after trying 2.3.2-beta3
but it crashes every time I try to start the X11 server. I've
rebooted, reinstall a couple of times but no luck. X11 now just
crashes immediately. How does one downgrade X11?
Second, at least with 2.3.2_beta3 our application's dialogs now
frequently, but not always, pop to the upper left corner of the
desktop (dual monitors) after twiddling some of the dialog's
widgets.
Third, the application opens multiple connections to the X server
since it uses both Motif and QT4. With 2.3.2_beta3, some dialogs
created via PyQT are now causing the X11 server to crash; the main
app is Motif based.
Unfortunately, I have not been keeping up with all the 2.3.x
updates so I don't know how far back this problem goes. Prior to
this I was running 2.2.2 without these problems. I'll be happy to
try the various 2.2.x and 2.3.x release to see when the problem
was introduced if someone can tell me how to properly downgrade.
Thanks!
Mike
