  12 Compiling wxWindows samples with the Borland CBuilder</h2>
  13
  14 This document is available online <a href="http://biolpc22.york.ac.uk/wx/bc/ide.html">here</a>.<P>
  15
  16 <h2>
  17 Before you begin</h2>
  18 This refers to the <b>2.1.16</b> and 2.1.15 wxWindows distribution. It
  19 is my account of trying to compile the samples so I can use the Borland
  20 IDE to edit/compile/debug. I have used CBuilder 1.00 (2 patches, nice and
  21 fast), CBuilder 3 (slower), and CBuilder 4 (more recently).
  22
  23 <p>Make sure that the wx distribution is extracted to a path with no spaces
  24 in it, and preferably on the root of your drive. Borland's compilers sometimes
  25 have problems with spaces and with the long paths which occur if you try
  26 to place it in a tree like <tt>d:\compiler\gui\wx...</tt>
  27 <h2>
  28 Part 1 Build the library</h2>
  29 Build the <b>wx\wx32.lib</b> and related files using the command line compiler
  30 <br>Run a command prompt in the <tt>wx/src/msw</tt> directory and type
  31 <p><tt>set wxwin=pathtowx</tt>
  32 <br><tt>set bccdir=pathtobc4</tt>
  33 <br><tt>make -f makefile.b32</tt>
  34 <p>In my case this I extracted the wx distribution in <b>c:\</b> and the
  35 compiler is in <b>w:\borland\cb\bin</b> so this looks:
  36 <p><tt>set wxwin=c:\wx</tt>
  37 <br><tt>set bccdir=w:\borland\cb</tt>
  38 <br><tt>make -f makefile.b32</tt>
  39 <p>If this doesn't <b>compile</b>,
  40 <ul>
  41 <li>
  42 you've probably got the <b><tt>set wxwin</tt></b> command wrong,</li>
  43
  44 <li>
  45 or the path was not set by the Borland setup</li>
  46 </ul>
  47 If this doesn't <b>link</b>,
  48 <ul>
  49 <li>
  50 you've probably got the <b><tt>set bccdir</tt></b> command wrong</li>
  51 </ul>

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

 128 <p>In CBuilder 1 you can use <b>Open Project</b> to open the mak file and
 129 edit/compile/debug.
 130 <p>In CBuilder 3 and 4, then you can use <b>Open Project</b> and choose
 131 the Open Borland CBuilder 1 Project from the drop down file types. The
 132 system will modify the mak file and update it for you.
 133 <p>Now try compiling it in the ide.
 134 <h4>
 135 Hints:</h4>
 136
 137 <ul>
 138 <li>
 139 You can set it up for normal and debug modes (change the -v switch in CFLAG1
 140 and LFLAG)</li>
 141
 142 <li>
 143 If you get problems saying Project undefined, then copy the text using
 144 a simple editor like notepad to the file minimal.mak (I have had problems
 145 in CBuilder 1.00 with Unix style line endings)</li>
 146
 147 <li>
 148 If you want to avoid the warnings about hiding virtual methods add
 149 <b><tt>-w-hid</tt></b> to the CFLAG1 line</li>
 150
 151 <li>
 152 the #define WinMain WinMain line allows CBuilder to think it has a non-VCL
 153 <tt>main</tt> function</li>
 154
 155 <li>
 156 the USEUNIT macros tell CBuilder which other source files to include, without
 157 needing a VCL form</li>
 158
 159 <li>
 160 the condefs.h file defines the USEUNIT macros for non-VCL use</li>
 161
 162 <li>
 163 For the other samples, change the names of the cpp and rc files. If you
 164 have multiple files, just add more USEUNIT and USERC macros</li>
 165 </ul>
 166
 167 <h3>
 168 Solution 3</h3>
 169
 170 <ul>
 171 <li>
 172 download the wxWindows-2.1.16-bcb.zip file,</li>
 173
 174 <li>
 175 extract it</li>
 176
 177 <li>
 178 use the <b><tt>idetomak</tt></b> (CBuilder 1) or <b><tt>idetobpr</tt></b>
 179 (CBuilder 3/4) utility on the <b><tt>.ide</tt></b> file in the samples
 180 directory. This modifies the cpp source and makes a "suitable" mak or bpr file
 181 (at least in CBuilder 1/3/4).</li>
 182
 183 <li>
 184 add the location of the wx/include files in the project | options
 185 | directory dialog</li>
 186 </ul>
 187 I found in CBuilder 1 that the <tt>idetomak</tt> utility did not manage
 188 to convert all the samples, but <tt>idetobpr</tt> worked OK in CBuilder
 189 3 and 4. I have a report that not all the bpr files made in CBuilder 4
 190 are correct
 191 <h2>
 192 Error with ODBC32</h2>
 193 Sometimes you get an error saying that there are unresolved externals in
 194 ODBC. The solution is to run a command prompt in your <b><tt>wx\lib</tt></b> directory
 195 and use the <b><tt>implib</tt></b> command:
 196 <p><tt>C:\wx\lib&gt;<b>implib odbc32 c:\windows\system\odbc32.dll</b></tt>
 197 <p>This creates the necessary library, odbc32.lib
 198 <h2>
 199 Unresolved Problem</h2>
 200 <tt>In Borland CBuilder 1.00 (with linker service patch) I frequently
 201 get an error</tt>
 202 <p><tt>Turbo Incremental Link&nbsp; Version 1.0 Copyright (c) 1997 Borland

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