wxWidgets Sample compiling error

<< < (3/3)

Ceniza:
BUILD=debug will create a big library that you can debug (I don't really think you want that).
BUILD=release will create a smaller library with optimizations that you won't be able to debug (except if you feel like debugging asm code). However, you'll be able to debug your own code, so don't worry about it.

Hi I rebuild everything. with monolithic and share
And it compiled the sample of wxWidgets given by Code::Blocks. Ran perfectly :P
Thank You all for helping me understand the different options.


Now its time learn the use of wxWidgets. I found:
http://www.wxwidgets.org/docs/tutorials/hello.htm

It seems like a good start. So I copied the code and compile it in an empty project.

and boom i got errors again :(

Maybe before start using a framework like wx it's better to understand how a compiler and linker works. And what parameters you have to provide to the compiler and linker. An empty project has *no* options setup. How should C::B - and therefor the compiler/linker know against what to compile/link, where to search for things and so on. You (!) have to provide that information.

I really suggest you try the following: Try to compile a simple "hello wx world" thing from the *command line* without any IDE. Once this works go back to C::B, setup your project accordingly and use the fancy stuff an IDE provides you with correctly.

With regards, Morten.
