<title>Compiling wx Samples in the Borland IDE</title>

<h2>
|
||||
Compiling wxWindows samples with the Borland CBuilder</h2>
|
||||
|
||||
This document is available online <a href="http://biolpc22.york.ac.uk/wx/bc/ide.html">here</a>.<P>
|
||||
|
||||
<h2>
|
||||
Before you begin</h2>
|
||||
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)
|
||||
<p>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 <tt>d:\compiler\gui\wx...</tt>
|
||||
<h2>
|
||||
Part 1 Build the library</h2>
|
||||
Build the <b>wx\wx32.lib</b> and related files using the command line compiler
|
||||
<br>Run a command prompt in the <tt>wx/src/msw</tt> directory and type
|
||||
<p><tt>set wxwin=pathtowx</tt>
|
||||
<br><tt>set bccdir=pathtobc4</tt>
|
||||
<br><tt>make -f makefile.b32</tt>
|
||||
<p>In my case this I extracted the wx distribution in <b>c:\ </b>and the
|
||||
compiler is in <b>w:\borland\cb\bin </b>so this looks:
|
||||
<p><tt>set wxwin=c:\wx</tt>
|
||||
<br><tt>set bccdir=w:\borland\cb</tt>
|
||||
<br><tt>make -f makefile.b32</tt>
|
||||
<p>If this doesn't <b>compile</b>,
|
||||
<ul>
|
||||
<li>
|
||||
you've probably got the <b><tt>set wxwin </tt></b>command wrong,</li>
|
||||
|
||||
<li>
|
||||
or the path was not set by the Borland setup</li>
|
||||
</ul>
|
||||
If this doesn't <b>link</b>,
|
||||
<ul>
|
||||
<li>
|
||||
you've probably got the <b><tt>set bccdir </tt></b>command wrong</li>
|
||||
</ul>

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

|

<p>In CBuilder 1 you can use <b>Open Project</b> to open the mak file and
|
||||
edit/compile/debug.
|
||||
<br>In CBuilder 3 and 4, then you can use <b>Open Project </b>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.
|
||||
<p>Now try compiling it in the ide.
|
||||
<h4>
|
||||
Hints:</h4>
|
||||
|
||||
<ul>
|
||||
<li>
|
||||
You can set it up for normal and debug modes (change the -v switch in CFLAG1
|
||||
and LFLAG)</li>
|
||||
|
||||
<li>
|
||||
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)</li>
|
||||
|
||||
<li>
|
||||
If you want to avoid the warnings about hiding virtual methods add <b><tt>-w-hid
|
||||
</tt></b>to the CFLAGS1 line</li>
|
||||
|
||||
<li>
|
||||
the #define WinMain WinMain line allows CBuilder to think it has a non-VCL
|
||||
<tt>main </tt>function</li>
|
||||
|
||||
<li>
|
||||
the USEUNIT macros tell CBuilder which other source files to include, without
|
||||
needing a VCL form</li>
|
||||
|
||||
<li>
|
||||
the condefs.h file defines the USEUNIT macros for non-VCL use</li>
|
||||
|
||||
<li>
|
||||
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</li>
|
||||
</ul>
|
||||
|
||||
<h3>
|
||||
Solution 3</h3>
|
||||
|
||||
<ul>
|
||||
<li>
|
||||
download the wxWindows-2.1.15-bcb.zip file,</li>
|
||||
|
||||
<li>
|
||||
extract it</li>
|
||||
|
||||
<li>
|
||||
use the <b><tt>idetomak</tt></b> (CBuilder 1) or <b><tt>idetobpr</tt></b>
|
||||
(CBuilder 3/4) utility on the <b><tt>.ide</tt></b> file in the samples
|
||||
directory. This modifies the cpp source and makes a "suitable" bpr file
|
||||
(at least in CBuilder 1/3/4).</li>
|
||||
|
||||
<li>
|
||||
add the location of the wx/include files in the project | options
|
||||
| directory dialog</li>
|
||||
</ul>
|
||||
I found in CBuilder 1 that the <tt>idetomak</tt> utility did not manage
|
||||
to convert all the samples, but <tt>idetobpr</tt> worked OK in CBuilder
|
||||
3 and 4. I have a report that not all the bpr files made inb CBuilder 4
|
||||
are correct
|
||||
<h2>
|
||||
Error with ODBC32</h2>
|
||||
Sometimes you get an error saying that there are unreolved externals in
|
||||
ODBC. The soltuion is to run a command prompt in your <b><tt>wx\lib </tt></b>directory
|
||||
and use the <b><tt>implib </tt></b>command:
|
||||
<p><tt>C:\wx\lib><b>implib odbc32 c:\windows\system\odbc32.dll</b></tt>
|
||||
<p>This creates the necessary library, odbc32.lib
|
||||
<h2>
|
||||
Unresolved Problem</h2>
|
||||
<tt>In Borland CBuilder 1.00 (with linker service patch) I frequently
|
||||
get an error</tt>
|
||||
<p><tt>Turbo Incremental Link Version 1.0 Copyright (c) 1997 Borland

||||
