 Take a look at

 src/osgText/CMakeFiles/osgText.dir/link.txt

 without the change you just made. In fact take a look at any of the link.txt 
 files for each OSG library. Thay all have /usr/lib/libm.dylib in there.

 I've added a entry of
 MATH_LIBRARY into the linking of osgText.  Could you do an
 svn update
 and see if the error is fixed?

 I got the svn version and no it doesn't fix it. All it does is move the

 /usr/lib/libm.dylib

 reference on the link line to a different place!

 The fact you've got errors but others under OSX
 haven't reported this
 (including myself) suggests that must be something else
 going w.r.t
 gcc/SDK's you are using on your machine.

 I'm sorry I haven't explained this well enough. The goal here is to *not* 
 have any explicit reference to libm.dylib on the link line.

 The symbols reside in the SDK version of the library at

 /Developer/SDKs/MacOSX10.4u.sdk/usr/lib/libm.dylib

 and *not* necessarily at

 /usr/lib/libm.dylib

 which is what the MATH_LIBRARY is set to. This is fine for UNIX but not Mac 
 as it should be the former that is used for a consistent build (if there are 
 Mac developers out there who disagree please correct me - I'm new to this).

 By omitting the explicit reference to libm.dylib the Mac build system takes 
 care of this automatically and gets the symbols from the SDK version of the 
 library.

 Users who are not seeing this problem have all the symbols they require in 
 /usr/lib/libm.dylib and are, as I understand it, lucky ;)

I'll will check what value is used on the OSX box that I was remote
compiling on.

Could you please remove the MATH_LIBRARY entry in the
src/osg/CMakeLists.txt and src/osgText/CMakeLists.txt to test your
theory about not needing it.

Robert.

Hi Robert,

If I set MATH_LIBRARY to  then it builds fine (with nothing on any on the

Also, if I set it to /Developer/SDKs/MacOSX10.4u.sdk/usr/lib/libm.dylib it also

Hi Paul,

When I was removing the MATH_LIBRARY entry from the
src/osgText/CMakeLists.txt  (the one that I had added to see it would
help you) I noticed that FreeType was listed but this isn't needed by
osgText, just by the freetype plugin so I have removed this as it's
not needed and potentially could extra complications that it needn't
have.  Could you try svn/trunk to see if it makes any difference.
I've attached the cleaned up osgText/CMakeLists.txt in case you just

2008-12-19 Thread Paul Fotheringham
Hi Robert,

Thanks for that. I tried with the latest code from SVN and a fresh build 
directory and I still got the same two unresolved symbols.

I'm off on holiday now so I won't have access to the MacOSX machine at work 
until I get back in January. I didn't realise you were busy doing the 2.7.8 
release. If you do get a spare moment at some point then IMO the blog entry I 
linked to in my first post is quite informative. Since I'm new to the Mac I 
have no idea if it's a really bad thing that the 10.4 SDK libs on my system 
have different symbols from the 10.4 system libs. It does sound dodgy to me and 
even though I can tweak things to get osgText to build I wouldn't be surprised 
if it doesn't run (I'm actually not bothered as we don't use that particular 
library).

Oh well, thanks anyway, and have a good christmas and maybe we can resume this 
in January. Hopefully in the meantime someone with good Mac knowledge can maybe 
wade in to clarify it all :)

Hi Robert,

I just tried 2.7.7 and it's still an issue there. Maybe only the Xcode project 
was fixed up?

 I believe this one has already been addressed in the 2.7.x

 could you try 2.7.7 or svn/trunk.

  Hi,
 
  I think I know what the problem is. I'm getting
 the same unresolved symbols building on MacOS 10.4 and OSG
 2.6.1 using cmake. Your link line has
 
  /usr/lib/libm.dylib
 
  rather than your SDK version of the library. I
 don't know much about these things myself as I've
 only been using a Mac for about 1 day now but this blog
 entry details the issue
 
  http://www.red-sweater.com/blog/246/missing-link
 
  As far as cmake goes, and I've only been looking
 at _that_ for about 2 days, it seems the problem is in the
 top-level CMakeLists.txt file where it has the line
 
  FIND_LIBRARY(MATH_LIBRARY m)
 
  wrapped in an IF(UNIX) clause.
 
  I think this particular line should also be wrappend
 in an IF(NOT APPLE) clause. Doing this fixes up the link
 lines for me and the problem goes away. As I say I'm
 certainly no Mac expert so maybe this isn't quite right.
 I'm certainly not confident enough to post it to
 osg-submissions :)
 
  I haven't looked at the Xcode project at all but I
 imagine something similar must be going on there?

Hi,

The error is

Linking CXX shared library ../../lib/libosgText.dylib
ld: Undefined symbols:
_acl_copy_ext_native referenced from CarbonCore expected to be defined in 
libSystem
_acl_copy_int_native referenced from CarbonCore expected to be defined in 
libSystem
_task_name_for_pid referenced from CarbonCore expected to be defined in 
libSystem

It depends on the configuration of your system and whether the SDK versions of 
the libraries match the system ones. On some OSX systems it will build fine and 
on some it won't. It all depends on whether the SDK libs are in sync. with the 
system ones as regards having all the required symbols.

The link to the blog entry in my first email explains this better than I can. 
As I understand it, the systems that work are simply getting away with it as 
the symbols required by the build process just happen to be all there in the 
system libraries. They ought to be consistently getting them from the SDK 
libraries.

I'm sorry I haven't explained this well enough. The goal here is to *not* have

The symbols reside in the SDK version of the library at

/Developer/SDKs/MacOSX10.4u.sdk/usr/lib/libm.dylib

and *not* necessarily at

/usr/lib/libm.dylib

which is what the MATH_LIBRARY is set to. This is fine for UNIX but not Mac as 
it should be the former that is used for a consistent build (if there are Mac 
developers out there who disagree please correct me - I'm new to this).

By omitting the explicit reference to libm.dylib the Mac build system takes 
care of this automatically and gets the symbols from the SDK version of the 
library.

Users who are not seeing this problem have all the symbols they require in 
/usr/lib/libm.dylib and are, as I understand it, lucky ;)

Hi Robert,

I use XCode 2.4.1 with projects generated using CMake 2.6 (patch 2).
I didn't compile in release mode, I'll give a try. I haven't tested any 
previous version, generally I build under Windows and I took the last 
version from the Osg website.


On the mailing list I read of people using 2.6 under Mac system, I'll 
check for this version too. Thanks
