try to build wxWidget hello-world
« on: April 05, 2006, 04:28:30 pm »
I try to compile a wxWidget hello-world example. No it compiles and links without any errors, but there is no exe.

Here is the build log

No, it does not link without errors. It fails to link:

You have several options to solve this. Either set WXUSINGDLL in the #defines panel in project options, or do not use the wxWidgets DLL, but a static library instead (don't do both!).

More info on this can be found on the FAQ page in our WiKi.

Thanks a lot! It works now.
