<title>Compiling wx Samples in the Borland IDE</title>
</head>
<body>
<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 <b>2.1.16</b> and 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 (more recently).
<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>
<a href="http://biolpc22.york.ac.uk/wx/bc/download.html">Download</a> a zip file which contains modified
cpp, mak and bpr files - it will overwrite your wx distribution cpp files!
<h3>
Solution 2</h3>
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">these contents</a></li>:
</ul>

<p><tt>#-----------------------------------------------------------------------------</tt>
<br><tt>$(PROJECT): $(OBJFILES) $(RESDEPEN)</tt>
<p><tt>#end of file</tt>
<br>&nbsp;
<ul>
<li>
&nbsp;modify the .cpp file to include
<a href="http://biolpc22.york.ac.uk/wx/bc/calendar_include.cpp">these lines</a>
near the top</li>
</ul>
<tt>#ifdef __BIDE__</tt>
<br><tt>#define _NO_VCL</tt>
<br><tt>#include "condefs.h"</tt>
<br><tt>#define WinMain WinMain</tt>
<br><tt>&nbsp;&nbsp; // USEUNIT ("another.cpp"); // use a line like this
if you have more than one .cpp file</tt>
<br><tt>&nbsp;&nbsp;&nbsp; USERC ("calendar.rc");</tt>
<br><tt>#endif</tt>
<br>&nbsp;
<p>In CBuilder 1 you can use <b>Open Project</b> to open the mak file and
edit/compile/debug.
<p>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 CFLAG1 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-2.1.16-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" mak or 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 in CBuilder 4
are correct
<h2>
Error with ODBC32</h2>
Sometimes you get an error saying that there are unresolved externals in
ODBC. The solution 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&gt;<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&nbsp; Version 1.0 Copyright (c) 1997 Borland
International</tt>
<br><tt>Fatal: Assertion failed: typeInx &lt; typeCnt at "ilinkdbg.c",
line 2060</tt>
<br><tt>Fatal: Access violation.&nbsp; Program terminated.</tt>
<br><tt>Error: Internal failure -- retrying link...</tt>
<br><tt>Fatal: Assertion failed: typeInx &lt; typeCnt at "ilinkdbg.c",
line 2060</tt>
<br><tt>Fatal: Access violation.&nbsp; Program terminated.</tt>
<p><tt>** error 2 ** deleting minimal.exe</tt>
<p>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.
