Title: Errors building with mingw
Post by: CDarcey on August 15, 2007, 03:22:28 am
I have installed current copies for Code:Blocks, wxWidgets, minGW and MSys.
I used the wizard to start a wxWidgets project using wxSmith, frame based.
Select all three options in wxWidgets Library Settings and use precompiled headers.
This produced 2 errors "A matching Debug/Release configuration...." I ignored these.
Added a wxgridsizer and wxGrid to the frame.
Build first came up with error: Platform.h (196) wx/setup.h not found.
I copied setup.h from wx/msw to try this out.
This seemed to fix the problem, but the linker then failed with: ld.exe  cannot find -lwxmsww28ud.

Can anyone advise on what I am doing wrong, or how this might be resolved ?

You have to add wxmsww28ud library to the project linker settings by pointing the directory that had it after you compiled wxWidgets. Usually wxdir\lib\gcc_dll or something like that.

Thanks for the response. There does not appear to be a directory of this name (or anything like it), I installed wxWidgets by downloading and running wxMSW-2.8.4-Setup.exe. Is there some other step required after this ?

Don't ignore these warnings unless you know exactly what you are doing. The warnings are pointing towards the possible wrong wx configurations.

You've downloaded the source of wxWidgets. You've to compile it first. :)

OK this is making sense, I did not realise that this build step was necessary until searching for instructions on howto.
Question: can you point me to some instructions for compiling wxWidgets using minGW that work. I have found a couple but these refer to v2.6.4 and fail anyway.

Remove reference to MSYS (C:\msys\1.0\bin) from PATH. Now open a command prompt and change the current directory to <wx-dir>\build\msw. Now issue the following command (an example).
Code
mingw32-make -f makefile.gcc BUILD=release SHARED=1 UNICODE=1 MONOLITHIC=1
If everything is ok, it will take about 15-20 mins (approx).

Success!. Thank you for the assistance, especially appreciated as this turned to be dumb user with wxWidgets and Code::Blocks the inocent victim.

I don't know if you still have your copy, but normally, wxWidgets build process copies setup.h in a directory and you have to put this directory in the search directories of the project settings of the compiler. This directory is for me :
C:\DevSofts\wxWidgets-2.8.4\lib\gcc_dll\mswu\wx where
where mswu may be replaced by msw$(SUFFIX) to be more portable
