wxDisplay

Hi I build wxWidgets as following:
'mingw32-make -f makefile.gcc USE_XRC=1 SHARED=1 MONOLITHIC=1 BUILD=release UNICODE=0 wxUSE_DISPLAY=1 VENDOR=cb'
This is explained in your 'samples/display/display.cpp' file of the wxWidget-2.6.2 distribution. But when I try to compile 'display.cpp' this is what the compiler spits:

Code: Select all

Pls some advice.

I changed in:

Code: Select all

include/wx/setup_inc.h
include/wx/msw/setup0.h
include/wx/msw/setup.h
lib/gcc_dll/msw/wx/setup.h

the line '#define wxUSE_DISPLAY 0' to '#define wxUSE_DISPLAY 1' but then when building the dll I get a error.
I don't think I needed to change that in all the files, prob. in one is enough but I don't know what one.
I could realy use some help here.

You have to set your options in

Code: Select all

include/wx/msw/setup0.h

and then copy that file to

Code: Select all

include/wx/setup.h

.

Then compile your library.

Note that you would be best served to delete the lib_gcc folder you have as well as the msw_gcc folder which is probably under "build".

Then rebuild your library.

thx for your reply.

Hi foun something, I think:
../../src/msw/display.cpp:63:22: multimon.h: No such file or directory
../../src/msw/display.cpp:69:19: ddraw.h: No such file or directory
whee should those 2 files be located because I can't locate them.
Pls help me

Both are probably microsoft headers, and as such are not part of the wxWidgets disttribution.

I believe to get these you have to download the DirectX SDK.

xxbartosxx · Post by **xxbartosxx** » Tue Oct 04, 2005 6:49 am

Hi,
I am downloading it right now, but isn't this a bit strange you would need this as it is nowhere documented?

Yust my 2

If you use DirectX, you need to download its SDK (should be present in newer versions of Platform SDK). If not, your platform SDK version is old and you should download newer one from MS.

xxbartosxx · Post by **xxbartosxx** » Tue Oct 04, 2005 9:57 am

I don't wanne use directx but if I wane compile wxWidget with support for wxDisplay, I am missing some headers like multimon.h & ddraw.h so he suggested to install the directx sdk. So I am downlodingb the file of 170megs at a speed of 12 KB/sec when my line can easely get 700KB/sec.
Got the sdk that first came out but I need the one that came out in august because i am on xp64 and the first one don't support that.
The reason I find it strange is that its nowhere documented that you needed the dx sdk if you wanted support for wxDisplay

mispunt · Post by **mispunt** » Tue Oct 04, 2005 10:08 am

It is strange indeed.. an other strange thing is that you only need 12 MB of the SDK

vasek · Post by **vasek** » Tue Oct 04, 2005 10:17 am

Unfortunately, DirectX functions in display.cpp aren't compiled using #ifdefs, so ddraw.h is required.

Btw, multimon.h could be found at ([email protected])

Code: Select all

// if you don't have multimon.h you can download the file from:
//
//  http://www.microsoft.com/msj/0697/monitor/monitortextfigs.htm#fig4
//

I installeed the directx sdk but still get the same error, pobably because I need to say where the directx libs and headerfiles are but I dont know how.
DXSDK_DIR is the enviroment variable that points to thedirectx sdk dir. so what do I need to add to my compile command so it finds the libs and includes

mispunt · Post by **mispunt** » Tue Oct 04, 2005 8:38 pm

I just moved the include files to the include directory of the compiler and the libs to the lib directory
