Title: problems with cross compiling
Post by: shadow_of__soul on February 21, 2008, 12:06:31 am
Hi,

i follow the instruction to configure codeblocks for cross compiling, and all go fine but i have some problems.

when i trying to compile the example code of the wxWidget this throw this errors:

/usr/include/wx-2.8/wx/defs.h:2806: error: conflicting declaration 'typedef struct GtkWidget*WXWidget'
/usr/include/wx-2.8/wx/defs.h:2597: error: 'WXWidget' has a previous declaration as `typedef void*WXWidget'
/usr/include/wx-2.8/wx/defs.h:2806: error: declaration of `typedef struct GtkWidget*WXWidget'
/usr/include/wx-2.8/wx/defs.h:2597: error: conflicts with previous declaration `typedef void*WXWidget'
/usr/include/wx-2.8/wx/defs.h:2806: error: declaration of `typedef struct GtkWidget*WXWidget'
/usr/include/wx-2.8/wx/defs.h:2597: error: conflicts with previous declaration `typedef void*WXWidget'

and other of the same type,how i see it, it's why it's using the linux lib for the include and not the windows libs (i have the precompiled pack of the wxWidget).

any know how i can change the path to include the files from the pre-compiled pack for windows and not the linux lib's?

Thanks for your help  :)

Regards,
Shadow.

These errors are not from the libs - it hasn't started linking yet.
You have defined __WXGTK__ somewhere, I just had the same problem yesterday.
If you are cross-compiling, you want __WXMSW__, not __WXGTK__.

Hi,

surely that it's the problem, but i think it's why i'm using the linux lib's, why the code what i'm trying to compile it's the code created by the template of wxWidget (when you create a new project) whiteout modification.

to make more clear i include the log's of the build:

I expect you are using the wrong wx-config.

shadow,
 not to be rude, but it seems you need to understand more about normal compiling before you venture into cross-compiling.
 wx-config is a build tool that generates the appropriate build flags based on your wxwidgets configuration.
 it is invoked by code::blocks via a backticked expression in your build options.
 you are using the one for the linux version, you need to find or build one for your cross-compiled wxwidgets libs, or determine what your build flags should be, and put them in the appropriate places instead.

Hi,

well, i'm asking that, of course the project have wx-config in the build options, what i dont know how to do it, it's how to use my cross compiled libs in the project and not the linux lib.

if i use what you tell me, i need to change the config of wx-config or add some flag to link the libs what i want, but i dont know how to do it or what flags i need to use :s

Regards,
Shadow.

You should know where your compiled wxWidgets is.
Look in <path_to_your_wxMSW>/lib/wx/config there should be a shell-script for every wxWidgets version you compiled (e.g. unicode / ansi / debug etc.) called something like gtk2-unicode-release-2.8 (that's a wx-config for linux).

Use this with absolute paths instead of wx-config in the cross-compiling target of your project.
Remove the wx-config from your projects build options and put it into your build-targets options, so you can have the linux and the cross-build in one project.
