On Mac and on Windows XP the first call of to a wxWidgets method of the loaded (and statically linked) plugin leads to an segmentation fault and yet I do not understand why. If you statically linked wxWidgets with both the main app and your dll, you have two distinct instances of wxWidgets. Did you...

Obviously things might vary from platform to platform... So on Ubuntu I have no problems at all. I can link the plugin statically and load it into the (static linked) main application. On Mac and on Windows XP the first call of to a wxWidgets method of the loaded (and statically linked) plugin leads...

Yeah, thats why I finally linked both (main and plugin) against the dynamic dll wxWidgets versions. BUT: Actually I preferred to have a static main application to distribute in order to avoid to supply individual widgets dlls to the end user; except for those I myself developed as loadable modules h...

Is this possible? Yes, for sure :-) Well, on WinXP using wxPack it is - so far - not possible. If I build the main application static and the loadable plugin static, the programm simply crashes when I try to load the plugin. Wenn I compile the plugin against the dll-version of wxWidgets, the load d...

Hi,

I have a very basic question regarding the possibility to load dynamic applications (wxDynamicLibrary) into a statically linked wxWidgtes Application.

Is this possible?

If yes which (gcc) linker options are necessary on MAC and Windows?

Thanks a lot!

Yes, sorry, I meant I DID NOT experience corresponding problems on Windows.

However, the basic problem was a comparison of two doubles. I have no idea why this did not lead to any problems on Windows. For Linux I used now the simple solution: convert it to integer.

Thanks for your help!!!

Thanks for the hint!
However, I did experience this problem on Windows, so it cannot be a principle representation issue with respect to floating point numbers?

Actually this seems to be a plain c++ float/double precision issue: float a; a = 0.1; ------> results to a = 0.100000001 double c; c= 0.1; ------> results to a = 0.10000000000000001 double e; e = 100.0/1000.0; ------> results to a = 0.10000000000000001 Has anybody a hint how to get rid of this impre...

Hi, I am using the unicode version of wxWidgets 2.8.7 on Linux. The "ToDouble" conversion method shows a strange behavior: wxString test ("1.0"); double testd; test.ToDouble(&testd); ----> testd will have a value of 1 wxString test ("1.1"); double testd; test.ToDouble(&testd); ----> testd will have ...
