Compiling wxWindows samples with the Borland CBuilder
This document is available online here.
Before you begin
This refers to the 2.1.15 wxWindows distribution. It is my account of trying
to compile the samples so I can use the Borland IDE to edit/compile/debug.
I have used CBuilder 1.00 (2 patches, nice and fast) CBuilder 3 (slower)
and CBuilder 4 (only occasionally)
Make sure that the wx distribution is extracted to a path with no spaces
in it, and preferably on the root of your drive. Borland's compilers sometimes
have problems with spaces and with the long paths which occur if you try
to place it in a tree like d:\compiler\gui\wx...
Part 1 Build the library
Build the wx\wx32.lib and related files using the command line compiler
Run a command prompt in the wx/src/msw directory and type
set wxwin=pathtowx
set bccdir=pathtobc4
make -f makefile.b32
In my case this I extracted the wx distribution in c:\ and the
compiler is in w:\borland\cb\bin so this looks:
set wxwin=c:\wx
set bccdir=w:\borland\cb
make -f makefile.b32
If this doesn't compile,
-
you've probably got the set wxwin command wrong,
-
or the path was not set by the Borland setup
If this doesn't link,
-
you've probably got the set bccdir command wrong
To make the samples
Solution 1
Download a zip file which contains modifed
cpp, mak and bpr files - it will overwrite your wx distribution cpp files!
Solution 2
Creating the files by hand . This is for the calendar sample; you will
have to change the names for the other samples
-
Create a calendar.mak file [must have the same name as the cpp file] in
a plain text editor with this contents
#-----------------------------------------------------------------------------
#this is for Borland CBuilder IDE v1 and 3
#add a \ at the end of the lines if you editor breaks the long
lines up
#copy this into notepad and save from there
#-----------------------------------------------------------------------------
!ifndef BCB
BCB = $(MAKEDIR)\..
!endif
PROJECT = calendar.exe
OBJFILES =
RESFILES = calendar.res
RESDEPEN = $(RESFILES)
LIBFILES =
#-----------------------------------------------------------------------------
CFLAG1 = -Od -v -a1 -c
# -Od disable optimisations -v debug -a1 byte align -c compile
only (matches my make for the library)
CFLAG2 = -DINC_OLE2;__WIN95__;__WXMSW__;__WINDOWS__;WIN32;__BIDE__;-I$(BCB)\include;$(BCB)\include\vcl;..\..\include;
-H=BC32.CSM
PFLAGS =
RFLAGS = -DINC_OLE2;__WIN95__;__WXMSW__;__WINDOWS__;WIN32;__BIDE__;
-I$(BCB)\include;..\..\include;
LFLAGS = -L$(BCB)\lib;$(BCB)\lib\obj;..\..\lib -aa -Tpe -v -V4.0
-c
IFLAGS =
LINKER = ilink32
#-----------------------------------------------------------------------------
ALLOBJ = c0w32.obj $(OBJFILES)
ALLRES = $(RESFILES)
ALLLIB = $(LIBFILES) vcl.lib xpm.lib wx32.lib ole2w32.lib import32.lib
odbc32.lib cw32mt.lib
#you will need to add other libraries to the line above, eg the
jpeg.lib for image samples
---------------------------------------------------------------------------
.autodepend
#-----------------------------------------------------------------------------
$(PROJECT): $(OBJFILES) $(RESDEPEN)
#end of file
-
modify the .cpp file to include these
lines near the top
#ifdef __BIDE__
#define _NO_VCL
#include "condefs.h"
#define WinMain WinMain
// USEUNIT ("another.cpp"); // use a line like this
if you have more than one .cpp file
USERC ("calendar.rc");
#endif
In CBuilder 1 you can use Open Project to open the mak file and
edit/compile/debug.
In CBuilder 3 and 4, then you can use Open Project and choose
the Open Borland CBuilder 1 Project from the drop down file types. The
system will modify the mak file and update it for you.
Now try compiling it in the ide.
Hints:
-
You can set it up for normal and debug modes (change the -v switch in CFLAG1
and LFLAG)
-
If you get problems saying Project undefined, then copy the text using
a simple editor like notepad to the file minimal.mak (I have had problems
in CBuilder 1.00 with Unix style line endings)
-
If you want to avoid the warnings about hiding virtual methods add -w-hid
to the CFLAGS1 line
-
the #define WinMain WinMain line allows CBuilder to think it has a non-VCL
main function
-
the USEUNIT macros tell CBuilder which other source files to include, without
needing a VCL form
-
the condefs.h file defines the USEUNIT macros for non-VCL use
-
For the other samples, change the names of the cpp and rc files. If you
have multiple files, just add more USEUNIT and USERC macros
Solution 3
-
download the wxWindows-2.1.15-bcb.zip file,
-
extract it
-
use the idetomak (CBuilder 1) or idetobpr
(CBuilder 3/4) utility on the .ide file in the samples
directory. This modifies the cpp source and makes a "suitable" bpr file
(at least in CBuilder 1/3/4).
-
add the location of the wx/include files in the project | options
| directory dialog
I found in CBuilder 1 that the idetomak utility did not manage
to convert all the samples, but idetobpr worked OK in CBuilder
3 and 4. I have a report that not all the bpr files made inb CBuilder 4
are correct
Error with ODBC32
Sometimes you get an error saying that there are unreolved externals in
ODBC. The soltuion is to run a command prompt in your wx\lib directory
and use the implib command:
C:\wx\lib>implib odbc32 c:\windows\system\odbc32.dll
This creates the necessary library, odbc32.lib
Unresolved Problem
In Borland CBuilder 1.00 (with linker service patch) I frequently
get an error
Turbo Incremental Link Version 1.0 Copyright (c) 1997 Borland
International
Fatal: Assertion failed: typeInx < typeCnt at "ilinkdbg.c",

** error 2 ** deleting minimal.exe
I have not been able to track down why sometimes this error occurs and
other times it is OK
I have not seen this in Cbuilder 3 or 4
