4.6 Compiling in Windows with Borland

This section describes how to use Borland's C++ compilers to compile programs that use Rogue Wave's Money.h++ class library.

These instructions assume that the Borland include files and libraries are in the locations specified by the file bcc32.cfg for 32-bit compiles. If not, you will have to specify -I and -L flags as well, or change your configuration file. (See the Borland User's Guide for instructions.)

Let's say that we have a file named myapp.cpp and that we are compiling it in a Windows NT MS-DOS command prompt. Let's also say that the Money.h++ and Tools.h++ header file include path is

c:\rwav\workspaces\WINNT4\BORLANDC++_Builder_30\4s

and that we have built a static, multithreaded version of Money.h++ named mny4s.lib. Then we can compile myapp.cpp with the Borland C++ compiler with the following command (all on one line):

bcc32 -Ic:\rwav\workspaces\WINNT4\BORLANDC++_Builder_30\4s myapp.cpp
  c:\rwav\workspaces\WINNT4\BORLANDC++_Builder_30\4s\lib\tls4s.lib 
  c:\rwav\workspaces\WINNT4\BORLANDC++_Builder_30\4s\lib
    \mny4s.lib

This command will compile and link in one step.

• The -I option tells the compiler where to find the header files.

• The paths
  c:\rwav\workspaces\WINNT4\BORLANDC++_Builder_30\4s\lib\tls4s.lib
  and
  c:\rwav\workspaces\WINNT4\BORLANDC++_Builder_30\4s\lib\mny4s.lib
  are the full path names for no standard library, no debugging, static Tools.h++ and Money.h++ libraries for Borland C++. (Substitute as appropriate.)

Money.h++ can be built as a DLL using Borland C++ under Windows 95 and Windows NT. Be sure to review the readme file for additional tips on using the DLL.

To use the DLL version of Money.h++, you must:

1. Use the Borland runtime library (RTL) DLL.

2. Define the macros _RWDCMLDLL, _RWTOOLSDLL, and _RTLDLL on the compiler command line. This tells the header files to configure for dynamic linking.

3. Link your program with the import libraries. Example names of the import libraries are:

• Release Version (no symbolic debugging or assertions):

Money.h++: mny4d.lib

Tools.h++: tls4d.lib

Borland runtime library: cw32imt.lib

• Debug Version (with symbolic debugging and assertions):

Money.h++: mny7d.lib

Tools.h++: tls7d.lib

Borland runtime library: cw32imt.lib

The Money.h++ DLL is mny<build#>d.dll. Section 2.6 explains build numbers. The Tools.h++ Build Guide provides the name of the Tools.h++ DLL file.

4. When you run your program, the Money.h++ DLL and the Borland RTL DLL must be in one of the following places:

• the current directory

• the \WINDOWS directory

• the \WINDOWS\SYSTEM directory

• the directory containing the executable file for your program

• a directory listed in the PATH environment variable

• the list of directories mapped in a network

If you get exceptions, especially in *.DLLs, and you can't figure out where they're coming from, you may have incompatible *.DLLs running. Check for incompatible .DLLs in the directories indicated above.

When using the Borland C++ IDE, you must define the Rogue Wave include path, for example, <rw_root>\workspaces\WINNT4\BORLANDC++_Builder_30\4s, to every project. Use menu selection Options | Project | Directories.

You should also add the appropriate Money.h++ library to your Project Window. See the Borland User's Guide for instructions.
