Hi,

we recently tried to compile our plugin using the C4D 11 SDK. On windows this worked without problems, on OSX though there are strange things happening now:

I was able to compile and link everything without problems, when opening the plugin in C4D though, the program crashed. C4D crash report told me that a dynamic_cast failed. I checked the XCODE project settings and found out that "Enable C++ runtime type information" was disabled. I enabled this and recompiled - now linking fails, giving error messages like:

"typeinfo fo GeModalDialog", referenced from:
typeinfo for AboutDialog MainDialog.o
.
.
.
symbol(s) not found

Am I doing something completely wrong here? The code used to compile using 10.5 SDK without problems before...

Any ideas?

Many thanks

Markus

you really need to give more information about the classes involved and a little bit of code. Is the base class virtual? So is it really polymorphic?

Just a guess: This error looks as if the API library has not been recompiled with rtti enabled. (only the actual plugin library, so it fails to link with the non-rtti api lib)

Hi,

many thanks for your answers

Actually that was exactly what was happening (found that out yesterday but forgot to post an update here) :

I was under the assumption that the build options for my project propagated to the embedded _api project - they didn't. I enabled rtti in the api project, recompiled, all is well now

Thanks

Markus
