[Dev-C++] wxwindows problems again and again...

From: Neszt T. <ne...@ss...> - 2003-06-18 10:40:38

Hello!

I know, there were many questions and answers regarding wxwindows using
with dev-c++, but I'm still in trouble without solution.
I decided to try to solve again. I downloaded the newest version of
wxwindows (2.4.1). Atfer half an our I knew, I failed again.
Than I found the fantastic webpage:

  http://www.wxwindows.org/devcpp.htm

In the dev-C++ 4 section there are a lot of links which is not works, for
example, ftp://biolpc22.york.ac.uk/pub/ports/mingw32/extra.zip

So, I tried to do that step by step, but I couldn't.

And what is the error message? At this point of time this:


In file included from C:\DEV-C_~1\Include\wx\memory.h:20,
                 from C:\DEV-C_~1\Include\wx\object.h:25,
                 from C:\DEV-C_~1\Include\wx\wx.h:16,
                 from d:\work\programming\wx1\controls\controls1.cpp:23:
C:\DEV-C_~1\Include\wx\string.h:164: #error "Please define string
case-insensitive compare for your OS/compiler"
In file included from C:\DEV-C_~1\Include\wx\checklst.h:34,
                 from C:\DEV-C_~1\Include\wx\wx.h:55,
                 from d:\work\programming\wx1\controls\controls1.cpp:23:
C:\DEV-C_~1\Include\wx\msw\checklst.h:20: #error "wxCheckListBox class
requires owner-drawn functionality."


Sorry for my bad english,

Hello!

Hmmm..., now which language should I use? :)
No matter, I'll use English, so others can also read it.

wxWindows requires a LOT of #defines (or -Dxxx on the command line), 
which are used by the header files, to provide cross-platformness. The 
errors you got, were because you didn't actually specify which OS do you 
compile for. That's why you get errors about case insensitive 
string-comparison functions, as it is:
stricmp() under Windows, but
strcasecmp() under Linux (or UNIX?),
so wxWindows cannot "find it out". That's why you need to specify the 
OS, THEN wxWindows WILL be able to "find out" the proper comparison 
function.
So, what flags do you need? Well, you can try digging it out from the 
original wxWindows distribution's makefile.g95 and makeg95.env and such 
files, OR you might try using these (my digging :)

-D_X86_=1 -DWIN32 -D_WIN32 -DWINVER=0x0400 -D__WIN95__ -D__GNUWIN32__
-D__WIN32__ -DSTRICT -DHAVE_W32API_H -D__WXMSW__ -D__WINDOWS__


Tell me if you succed.

kénytelen voltam "mellőzni" a gépelést az utóbbi 4 napban.

If plunge yourself deep into the wxWindows code (especially into the 
headers), you'll notice that some of those flags are needed. Some are 
defined by the others, some are not. Something like:

#ifdef WIN32
#  define _WIN32
#endif

etc. I don't recall exactly, which are defined, which are not. So, it 
may be true, that not all of them is needed, but perhaps they are all 
needed. All I know is, that when I removed most flags I could, but still 
get my program to compile (minimal flags, WIN32 or one of them only, and 
a lot others removed) resulted in a run time crash. So, I suppose those 
defines do something good, so I decided to define them all. After all: 
these flags were digged out by me from the wxWindows MINGW makefiles 
(makeg95.env), and wxWindows uses these flags for it's sample programs 
too, so I think they are a must. I am talking about 2.4.0 however, but I 
don't think 2.4.1 has changed radically in this field...
I have played around with it for some time. Maybe you can try different 
settings too.

So, all in all: those defines are essential for a working wxWindows 
program. Don't ask why! I don't know. All I know, when they are all 
specified, things work, when not, things crash (but compile). Odd... :)

I hope I made things more clear.

[Dev-C++] FREE download: a HOW-TO use wxWindows with Dev-C++

From: Yeoh H. <ye...@ye...> - 2003-06-20 01:53:49

Dear fellow Dev-C++ users,

Dev-C++ is a great tool and with its many DevPaks, it is even more useful.
But sometimes you want to use some C++ library but couldn't find any DevPaks
for it. You don't really need a DevPak. What you need are the .a library
file(s) and the C++ header files. If the C++ library comes with source and
also contains the build scripts, you might be able to create the required .a
files. This is possible only if the configure scripts are also built for
MinGW. What follows is an account of one C++ adventure.

If you want to know how to create the required wxWindows .a library file for
use with Dev-C++ 4.9.8.0 (GCC 3.2), here's some information for you.
