      nm outputs this:
      [...]

      That looks pretty fine. Which Xcode 3 version did you use?

      Moving to XCode 4 and using the r14 sdk project makes the plugin run on r14 only - XCode 4.4 doesn't support OS X 10.5 (BaseSDK) anymore and it doesn't support PPC chips either.

      Best regards,

        I have read some hacky stuff on the internet about copying the 10.5 SDK folder from earlier Xcode versions to the Xcode 4.4 folder. Will that work or is it an unstable/unreliable solution?

          TBH, for me the easiest solution was to install 3.2.6 and 4.4 on the same machine (running Lion) and then use 3.2.6 for all builds except the R14 one, when I use 4.4. It means that for each build I can use the cinema4dsdk project which is correct for each version of Cinema as the basis, ensuring that the correct settings are in place for each one.

          It's a bit less convenient since it means I now have to use two development environments on the Mac but it avoids missing important settings for one or other build.

                  Unfurl is build for R13 using the R13 cinema4dsdk project so it must be the default (either Maxon's project or Xcode's) symbol stripping type.  This entire thing is a bit unnerving since it would rarely show up (now it is epidemic) and one cannot really test for this.  So, I'll have to change the strip type setting, run that command, and hope that the crashes magically vanish (for 15 plugins).  Not my favorite way to spend my weekend. 😞

                    Follow-up FYI. Turns out a few things went wrong (mixed-up project & target settings in Xcode 3). Although your target settings modified the stripping (should have happened in the project settings) and nm did report just a few symbols, the size of your dylib (680 kb) was sus**cious - and there had been a few symbols used that are related to debugging (e.g. the stack_chk_guard symbol).

                    Dragging the dylib on a hexeditor shows, that the symbols & debug symbols are still there. Might be caused by the mixed-up project/target settings or by XCode 3.2 - we discovered today that removing global symbol from a final linked dylib based on the r12 sdk didn't work anymore in XCode 3.2.6 (while it did with XCode 3.1 that we used for building r12). Xcode doesn't even warn you about that; you've to look into the log output to discover it. More on that later - we're preparing a document about it...

                    I've set up your plugin project based on the r13 sdk and the size shrinked down to 111 kb, symbols are stripped and the crash on 10.8.1 is gone.

                      I noticed that my plugin CD Symmetry Tools is in the list of plugins causing a crash, but the deployment settings in my plugin's project show that I am using the "Non-Global Symbols" setting in the release version:

                      Since I don't really know much about the specific project settings, I simply copied the cinema4dsdk project, deleted the source, added my own source code and then changed the Product Name to my plugin's name.

                      Do I need to change something else?

                      P.S. My plugins were compiled with the first R14.014 demo on a 32bit machine running Snow Leopard 10.6.8 and Xcode 4.2

                        Hi Dan,

                        This is confusing me, too. Because you've got Strip Style set to non-global symbols for release, so they should be stripped, but under strip linked product for release it says 'no'. Does that mean the symbols are being stripped or not? Beats me, I sure don't know.

                        And it's worrying because I also used the sdk project as the basis for the compile on R14 (though it is the 14.025 version if that makes any difference).

                          For the release build make sure stripping is enabled ("strip linked product -> Release: Yes"). Please check project and target settings for that.

                          Use the "nm <path> | c++filt -p -i" command to verify that new & delete symbols aren't exported.

                            OK, I've just discovered something. Since I have several machines and always prefer to install updates on a separate machine first, I have the first R14.014 demo, the release version R14.014 and the updated R14.025 demo available and there are different settings for the "Strip Linked Product" parameter in the cinema4dsdk project:
                            R14.014 demo:
                            Debug = Yes
                            Release = No

                            R14.014 release:
                            Debug = No
                            Release = No

                            R14.025 demo:
                            Debug = Yes
                            Release = Yes

                            So, maybe the latest settings are correct?

                                You can change that, but I think the target settings for debug already do that (for you).

                                  When I use that, it gives me an error:

                                    DOH! disregard that previous post. I was trying that through the network from a different machine. When I did that on the machine where I did the compile, it gave me this readout:

                                      Was that a debug build, or have you manually changed some settings or do you use some external libs? The "stack_chk_guard" isn't supposed to be in a release build, at least not in our usual builds.

                                      nm needs installed devtools on the machine to work.

                                      Best regards,

                                        Well, crap! Now I'm not sure where to set whether it's a Release or Debug build (I'm somewhat lost in Xcode 4).

                                        This was the only place where I could find a choice between Debug and Release:

                                        Is that only for the command line build?

                                          There is a XCode 4 transition guide @Apple: http://developer.apple.com/library/mac/#/legacy/mac/library/documentation/IDEs/Conceptual/Xcode4TransitionGuide/Introduction/Introduction.html

                                          To edit the scheme settings, press ALT-Cmd-R (or use the menu: Product -> Edit Scheme...). There you can switch between release, debug, etc.

                                            Thanks. I did figure that out by googling it, and discovered that it was set to "Release":

                                            Is there some other setting that needs to change, that's causing the "stack_chk_guard"? 
                                            I'm still compiling my original plugin project that was copied from the cinema4dsdk project from the R14.014 demo.

                                            Edit:
                                            Or does it really matter that the "stack_chk_guard" is showing up in the Terminal readout?

                                            Adios,
