Re: [osg-users] Build error on MAc OSX 10.4 and OSG 2.7.4
Hi Robert, If I set MATH_LIBRARY to then it builds fine (with nothing on any on the link lines). Also, if I set it to /Developer/SDKs/MacOSX10.4u.sdk/usr/lib/libm.dylib it also works fine (with /Developer/SDKs/MacOSX10.4u.sdk/usr/lib/libm.dylib on each link line). I must admit I'm puzzled as to why the string associated with MATH_LIBRARY is appearing on the link lines for all the libraries and not just libosg itself as none of the CMakeLists.txt files other than the one in the osg folder refer to it. Are the other libraries somehow inheriting this setting from the cmake settings in libosg?

Re: [osg-users] Build error on MAc OSX 10.4 and OSG 2.7.4
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.

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.

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.

Re: [osg-users] Build error on MAc OSX 10.4 and OSG 2.7.4
HI Paul, The core OSG library does link against the MATH_LIBRARY, but the other non of the other core libraries do. 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? 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. Robert.

Hi Robert, Thanks for looking into this. --- On Thu, 18/12/08, Robert Osfield robert.osfi...@gmail.com wrote: snip The core OSG library does link against the MATH_LIBRARY, but the other non of the other core libraries do. Apparently not on MacOSX using cmake :) 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 ;) Paul Robert.

Re: [osg-users] Build error on MAc OSX 10.4 and OSG 2.7.4
Hi Paul, I believe this one has already been addressed in the 2.7.x dev series, could you try 2.7.7 or svn/trunk. Robert.

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?

Re: [osg-users] Build error on MAc OSX 10.4 and OSG 2.7.4
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 Andrea Robert Osfield ha scritto: Hi Andrea, I'm not a OSX expert, but for those that are you don't provide quite enough info to know what might be up.
