wxWidgets/Code::Blocks Nightly Build/MinGW
« on: May 01, 2006, 09:30:27 pm »
Im having trouble compiling a wxWidgets application.

I follow this: Compiling_WxWidgets_With_MSYS-MinGW
I copy the libs it makes into my wxWidgets lib directory. I create a wxWidgets app and tell it my wxWidgets directory.
I link the libraries.

I compile and get:
main.cpp:: undefined reference to `_imp___ZN12wxAppConsole17CheckBuildOptionsEPKcS1_'
main.cpp:: undefined reference to `_imp___Z7wxEntryP11HINSTANCE__S0_Pci'
main.cpp:: undefined reference to `_imp__wxFrameNameStr'
main.cpp:: undefined reference to `_imp__wxDefaultSize' ... etc.

I guess I missed some steps, After creating a wxApplication project I put the minimal wx example into main.cpp.

Thanks, MVP.

Hello,

I usually build wxWidgets with MinGW by following these instructions:

http://forums.codeblocks.org/index.php?topic=1701.0

Moreover, instead of copying the libraries, you can define and use a global variable.

Best wishes,
Michael

PS.: Do not forget to post which C::B revision are you using, OS and eventually GCC version :).

Using April 30, 2006 nightly build, wxWidgets 2.6.3, Windows XP, MinGW (current)

Thanks for the reply, I followed the "Compile wxWidgets in Unicode mode" section.

Now I get a lot less errors. :)

Still 3 more though not sure why:
:: warning: ./wx_pch.h.gch/default_wx_pch.h.gch: created by version `3.4.4 (mingw special)', but this is version `3.4.2 (mingw-special)'
main.cpp:: undefined reference to `_imp___ZN8wxString6PrintfEPKcz'
:main.cpp:: undefined reference to `_imp___ZN12wxStringBase8InitWithEPKcjj'
:main.cpp:: undefined reference to `wxApp::Initialize(int&, char**)'

Which GCC version (not MinGW) are you using? If 3.4.2, you might want to update to GCC 3.4.5 (but before update win32api and binutils files).

Also did you check the include files and libraries are included correctly?

Best wishes,
Michael

Thanks again, I downloaded the updated core gcc, binutils, and g++, and overwrote them over my mingw installation, im guessing thats bad but the installer wouldnt grab the latest candidate, it was getting 3.4.4 not 3.4.5 and so I improvised.  :shock:

The include directories, etc. I left as default, I only set the base dir of wxWidgets.

Attachment shows the links.

Edit: Updating mingw stuff according to wiki

What I have done was to use the installer MinGW 5.0.2 (selected candidate), to update win32api and binutils files and then to download and install GCC 3.4.5. The installer just install 3.4.4 as candidate and IIRC 3.4.2 as stable. Na ja, to be honest, I have also copied and pasted my MinGW directory and installed GCC 4.1.0 from Ceniza. This means that I have 2 MinGW installations under C:

C:\MinGW
C:\MinGW_345

In case of need I can just switch to the other, but just renaming it to MinGW :).

Best wishes,
Michael

Concerning the libraries and include files, this is what I have in an application I was developing:

I have under compiler-->#defines:

Quote
__WX__
WINVER=0x0400
__GNUWIN32__
HAVE_W32API_H
__WXMSW__
WXUSINGDLL
wxUSE_UNICODE

Under other compiler-->Other options:

Quote
-pipe
-mthreads
-fexceptions
-Winvalid-pch

Under Linker-->Link libraries:

Quote
wxmsw26$(WX_SUFFIX)

Under Directories-->Compiler:

Quote
$(#WX.lib)\gcc_dll\msw$(WX_SUFFIX)
$(#WX.lib)\gcc_dll$(WX_CFG)\msw$(WX_SUFFIX)
$(#WX)\contrib\include
$(#WX.include)

Under Directories-->Linker:

Quote
$(#WX.lib)\gcc_dll
$(#WX.lib)\gcc_dll$(WX_CFG)

The wxWidgets library I use (unicode dll) is the same as the one I use to build C::B (as same are some of the settings :)).

Best wihses,
Michael

Hey thanks a lot, it seemed to work, It compiles now but when I go to run it it terminates right away with an error:

EDIT: Awesome, thanks dude, I just had to copy the setup.h into the includes folder and it works.  :D

Glad that it works :).

Anyway, be careful when you copy setup.h. Look at here (more info are available in the forum):
