In the accompanying article, Using TurboVision 1.03 - Putting the "Turbo" back in TurboVision we tell you how to correct two problems in the TV source files using the DOS Integrated Development Environment (IDE). If you'd rather recompile the source files from the command line and you've installed the command-line compiler (BCC.EXE), the process is very straightforward.
First, make the change to line 42 of TSCREEN.CPP that we describe
in the main article. Then, make \TVISION\SOURCE the current
directory by entering
cd\borlandc\tvision\source
To create a new OBJ file for the file TSCREEN.CPP, enter
bcc -I..\include -c -P -O1 -ml tscreen.cpp
In this command, we've set each of the compiler options by using the appropriate command-line parameters.
For example, the -I..\include parameter tells the compiler where to find the header files. The -c parameter tells the compiler to stop after it creates the object file, and the -P parameter forces the compiler to interpret the file as a C++ source file.
Toward the end of the command, the -O1 parameter tells
the compiler to create the smallest possible code, and the -ml
parameter tells the compiler to compile for the Large memory model.
If the command succeeds, BCC will display the following:
Borland C++ Version 3.1 Copyright (c) 1992 Borland International tscreen.cpp
Available memory 3566400
To use the same process to create the new OBJ file for NEW.CPP,
enter
bcc -I..\include -c -P -O1 -ml -DNDEBUGnew.cpp
In this command, the only difference is the -DNDEBUG
parameter, where the -D option creates the defined constant
NDEBUG. Now you can use TLIB as described in the main
article to replace the old versions of these modules.
