12Compiling wxWindows samples with the Borland CBuilder</h2>
13
14This document is available online <a href="http://biolpc22.york.ac.uk/wx/bc/ide.html">here</a>.<P>
15
16<h2>
17Before you begin</h2>
18This refers to the 2.1.15 wxWindows distribution. It is my account of trying
19to compile the samples so I can use the Borland IDE to edit/compile/debug.
20I have used CBuilder 1.00 (2 patches, nice and fast) CBuilder 3 (slower)
21and CBuilder 4 (only occasionally)
22<p>Make sure that the wx distribution is extracted to a path with no spaces
23in it, and preferably on the root of your drive. Borland's compilers sometimes
24have problems with spaces and with the long paths which occur if you try
25to place it in a tree like <tt>d:\compiler\gui\wx...</tt>
26<h2>
27Part 1 Build the library</h2>
28Build the <b>wx\wx32.lib</b> and related files using the command line compiler
29<br>Run a command prompt in the <tt>wx/src/msw</tt> directory and type
30<p><tt>set wxwin=pathtowx</tt>
31<br><tt>set bccdir=pathtobc4</tt>
32<br><tt>make -f makefile.b32</tt>
33<p>In my case this I extracted the wx distribution in <b>c:\ </b>and the
34compiler is in <b>w:\borland\cb\bin </b>so this looks:
35<p><tt>set wxwin=c:\wx</tt>
36<br><tt>set bccdir=w:\borland\cb</tt>
37<br><tt>make -f makefile.b32</tt>
38<p>If this doesn't <b>compile</b>,
39<ul>
40<li>
41you've probably got the <b><tt>set wxwin </tt></b>command wrong,</li>
42
43<li>
44or the path was not set by the Borland setup</li>
45</ul>
46If this doesn't <b>link</b>,
47<ul>
48<li>
49you've probably got the <b><tt>set bccdir </tt></b>command wrong</li>
50</ul>

54To make the samples</h2>
55
56<h3>
57Solution 1</h3>
58
59<h4>
60<a href="http://biolpc22.york.ac.uk/wx/bc/download.html">Download</a> a zip file which contains modifed
61cpp, mak and bpr files - it will overwrite your wx distribution cpp files!</h4>
62
63<h4>
64Solution 2</h4>
65Creating the files by hand . This is for the calendar sample; you will
66have to change the names for the other samples
67<ul>
68<li>
69Create a calendar.mak file [must have the same name as the cpp file] in
70a plain text editor with <a href="http://biolpc22.york.ac.uk/wx/bc/calendar.mak">this contents</a></li>
71</ul>

111<p><tt>#end of file</tt>
112<br>&nbsp;
113<ul>
114<li>
115&nbsp;modify the .cpp file to include these<a href="http://biolpc22.york.ac.uk/wx/bc/calendar_include.cpp">
116lines </a>near the top</li>
117</ul>
118<tt>#ifdef __BIDE__</tt>

123if you have more than one .cpp file</tt>
124<br><tt>&nbsp;&nbsp;&nbsp; USERC ("calendar.rc");</tt>
125<br><tt>#endif</tt>
126<br>&nbsp;
127<p>In CBuilder 1 you can use <b>Open Project</b> to open the mak file and
128edit/compile/debug.
129<br>In CBuilder 3 and 4, then you can use <b>Open Project </b>and choose
130the Open Borland CBuilder 1 Project from the drop down file types. The
131system will modify the mak file and update it for you.
132<p>Now try compiling it in the ide.
133<h4>
134Hints:</h4>
135
136<ul>
137<li>
138You can set it up for normal and debug modes (change the -v switch in CFLAG1&nbsp;
139and LFLAG)</li>
140
141<li>
142If you get problems saying Project undefined, then copy the text using
143a simple editor like notepad to the file minimal.mak (I have had problems
144in CBuilder 1.00 with Unix style line endings)</li>
145
146<li>
147If you want to avoid the warnings about hiding virtual methods add <b><tt>-w-hid
148</tt></b>to the CFLAGS1 line</li>
149
150<li>
151the #define WinMain WinMain line allows CBuilder to think it has a non-VCL
152<tt>main </tt>function</li>
153
154<li>
155the USEUNIT macros tell CBuilder which other source files to include, without
156needing a VCL form</li>
157
158<li>
159the condefs.h file defines the USEUNIT macros for non-VCL use</li>
160
161<li>
162For the other samples, change the names of the cpp and rc files. If you
163have multiple files, just add more USEUNIT and USERC macros</li>
164</ul>
165
166<h3>
167Solution 3</h3>
168
169<ul>
170<li>
171download the wxWindows-2.1.15-bcb.zip file,</li>
172
173<li>
174extract it</li>
175
176<li>
177use the <b><tt>idetomak</tt></b> (CBuilder 1) or&nbsp; <b><tt>idetobpr</tt></b>
178(CBuilder 3/4) utility on the <b><tt>.ide</tt></b> file in the samples
179directory. This modifies the cpp source and makes a "suitable" bpr file
180(at least in CBuilder 1/3/4).</li>
181
182<li>
183add the location of the wx/include files in the&nbsp; project | options
184| directory dialog</li>
185</ul>
186I found in CBuilder 1 that the <tt>idetomak</tt> utility did not manage
187to convert all the samples, but <tt>idetobpr</tt> worked OK in CBuilder
1883 and 4. I have a report that not all the bpr files made inb CBuilder 4
189are correct
190<h2>
191Error with ODBC32</h2>
192Sometimes you get an error saying that there are unreolved externals in
193ODBC. The soltuion is to run a command prompt in your <b><tt>wx\lib </tt></b>directory
194and use the <b><tt>implib </tt></b>command:
195<p><tt>C:\wx\lib><b>implib odbc32 c:\windows\system\odbc32.dll</b></tt>
196<p>This creates the necessary library, odbc32.lib
197<h2>
198Unresolved Problem</h2>
199<tt>In Borland CBuilder 1.00 (with linker service patch)&nbsp; I frequently
200get an error</tt>
201<p><tt>Turbo Incremental Link&nbsp; Version 1.0 Copyright (c) 1997 Borland

210<p><tt>** error 2 ** deleting minimal.exe</tt>
211<p>I have not been able to track down why sometimes this error occurs and
212other times it is OK
213<br>I have not seen this in Cbuilder 3 or 4
