1. HOW TO GET HELP
-------------------
If you have any problems, please read this file, the
HELPME!.DOC and other files in your DOC subdirectory, and the
Turbo C++ manuals first. If you still have a question and need
assistance, help is available from the following sources:
1. Type GO BPROGB on the CompuServe bulletin board system for
instant access to the Borland forums with their libraries of
technical information and answers to common questions.
If you are not a member of CompuServe, see the enclosed
special offer, and write for full details on how to receive
a free IntroPak containing a $15 credit toward your first
month's on-line charges.
2. Check with your local software dealer or users' group.
3. Borland's TECHFAX service. Call (800) 822-4269 for a FAX
catalog of entries.
4. If you have an urgent problem that cannot wait and you have
sent in the license agreement that came with the package,
you may call the Borland Technical Support Department at
(408) 438-5300. Please have the following information ready
before calling:
a. Product name and serial number on your original
distribution disk. Please have your serial number ready
or we will be unable to process your call.
b. Product version number. The version number for Turbo
C++ can be displayed by pressing Alt-H/A.
c. Computer brand, model, and the brands and model numbers of
any additional hardware.
d. Operating system and version number. (The version number
can be determined by typing VER at the DOS prompt.)
e. Contents of your AUTOEXEC.BAT file.
f. Contents of your CONFIG.SYS file.
2. INSTALLATION
----------------
You MUST use the INSTALL program to install Turbo C++. The
files on the distribution disks are all archived and have to be
properly assembled. You cannot do this by hand!
IMPORTANT!
If you want to create backup copies of your disks, make sure
that you put the backup on the same type of disk as the
source. If you're backing up the 5 1/4 inch 1.2 Mb disk set,
use only blank 5 1/4 inch 1.2 Mb disks for backup, etc. The
installation will not work correctly if you do not use the
same media type for the backup disks.
To start the installation, change your current drive to the one
that has the install program on it and type INSTALL. You will
be given instructions in a box at the bottom of the screen for
each prompt. For example, if you will be installing from drive
A:, type:
A:
INSTALL
- This INSTALL handles the installation of both the compiler
and tools in one operation, and allows several new
configuration options.
- After installation, make sure you insert \TC\BIN - or
whatever you selected as your BIN directory - into
your DOS path so the executable files can be found.
- Note: The list of files is contained in a separate file
called FILELIST.DOC, which will appear in the target
directory you specify during installation.
- After your initial installation, you can run INSTALL again to
add elements you omitted the first time. Just select the
items you want to add in the INSTALL options screen. Because
some things you may want to save could be overwritten, review
the following items to make sure you don't lose important
information:
1. Selecting CMD (the Command-line compiler) causes an
overwrite of any existing turboc.cfg & tlink.cfg file
with path information provided in that INSTALL session.
Any switches other than -L (library path) and -I
(include path) will not be preserved.
2. Selecting IDE will reset the include and library paths
to those provided in that INSTALL session.
3. By selecting any one of the following, the help file
paths and choices for THELP.CFG will reflect the current
session's installation choices:
a. CMD - command-line compiler
b. IDE - integrated environment
4. Alterations to headers or startup files will be
overwritten if any library models are selected.
In general, any selection you make of something installed
earlier will cause an overwrite of the earlier version
without prompting.
You should read the rest of this README file to get further
information about this release before you do the installation.
3. FEATURES
------------
Turbo C++ 3.0 includes big speed and capacity gains. Here are
some important features found in this version:
- DPMI services for increased capacity
- C++ 2.1 support, including the new nested class specifications,
and support of C++ 3.0 templates.
- Support for pre-compiled headers for substantial time savings
during subsequent recompiles.
- Color syntax highlighting
- Unlimited Undo/Redo replacing previous 'restore line' capability
- Added library functions for compatibility with other runtime
libraries, and addition of support for long double parameters
in math functions. (Please refer to On-line Help for details.)
- New MAKE features. (Please see the MAKE chapter in the User's
Guide for details.)
- Added BGI (Borland Graphics Interface) fonts and support. (See
"New BGI fonts" below.)
- A resident DPMI kernel program, DPMIRES.EXE. (See "DPMI" below.)
- THELP now allows you to switch between help files without
unloading and reloading. (Please see UTIL.DOC for details.)
NEW BGI FONTS
-------------
Several new fonts have been added to the Borland Graphics Interface:
Name Value Description
-------------------------------------------
SCRIPT_FONT 5 Stroked script font
SIMPLEX_FONT 6 Stroked simplex font
TRIP_SCR_FONT 7 Stroked triplex script font
COMPLEX_FONT 8 Stroked complex font
EURO_FONT 9 Stroked European font
BOLD_FONT 10 Stroked bold font
The fonts in the BGI now support the full ASCII character set.
DPMI
----
TC.EXE, TCC.EXE, and TLINK.EXE are now hosted under DPMI. These files
support protected-mode compilation and replace the files of the same
name in Turbo C++ Second Edition. Turbo C++ Second Edition should
continue to be used in instances where real-mode compilation is desired.
If you encounter a "machine not in database" message while attempting
to run the compiler, run the DPMIINST program to add your machine
configuration to the DPMI server database.
This version includes a resident DPMI host program, DPMIRES.EXE, that
allows you to preload the server before invoking TC, TCC, or any other
DPMI-hosted executables. If you want to run such hosted EXEs in a
Windows Standard Mode DOS window, you should run DPMIRES.EXE before
loading Windows. To do this, enter the following commands at DOS:
set DPMIMEM=MAXMEM 2000
dpmires
win /s
If you want to limit the amount of extended memory used by the
DPMI-hosted executables, an environment variable called DPMIMEM
can be set to do so. For instance, the command
set DPMIMEM=MAXMEM 2000
reserves about 2 Mb of memory for DPMIRES. The number after MAXMEM
can be adjusted, but cannot be lower than 1000.
The hosted executables cannot spawn each other when SHARE is loaded.
For instance, if you run MAKE on a file which in turn calls MAKE
again, you will get a sharing violation. In this specific case,
you can call the real mode version, MAKER, within the given makefile,
and a sharing violation won't occur.
4. IMPORTANT INFORMATION
-------------------------
- When using Brief with THELP, make sure to use Brief's -p
switch to ensure that the thelp window will be visible.
- We recommend that you use the following mouse drivers with
this product:
Microsoft Mouse version 7.04 or later;
Logitech Mouse version 5.01 or later;
Genius Mouse version 9.06 or later.
- If you get a "floating point formats not linked" message at
runtime, put the following somewhere in your source files:
extern void _floatconvert();
#pragma extref _floatconvert
This will force inclusion of floating point formats, which
may not be linked to reduce executable size.
COMPILER
- The default extension for source files to the command-line
compiler is .CPP; that is, if you enter
TCC -c test
the compiler will search for test.cpp, and give an error if a
file of that name cannot be found. If you want to have the
command-line compiler assume a .c extension and C language
source, use the command-line option -P-c. For more
information, see "The command-line compiler" in the User's
Guide.
- Note that the Generate COMDEFs choice under
Options|Compiler|Advanced Code Generation and the -Fc command-
line option are only supported in the C language. Linker errors
will result if you attempt to use a communal variable in C++.
- The macros min() and max() are not defined when stdlib.h is
compiled as C++ (to allow their use in 3rd party libraries,
etc.).
- Note that SYMDEB creates .SYM files for use in debugging;
Turbo C++ creates .SYM files for pre-compiled headers. They
are not compatible and collisions should be avoided by
setting the name of the pre-compiled header file (using -
H=filename).
- There is now full support of distance modifiers (near and
far) used for class member pointers. Here are two sample
declarations and their meanings:
void (A::* far var) ();
this is a far variable 'var' of type 'void (A::*)()';
void (far A::* var) ();
this is a 'default distance' variable 'var' of type
'void (far A::*)()'
- If you use C++ templates, and use a separate TLINK command
line rather than letting TCC invoke TLINK, you should make
sure that you turn on case-sensitive links with the /c switch.
- Incorrect code will be generated if you have a statement of
the type "A op B" where either A or B is an enum and the
other operand is a long, and "op" is one of the following
operators:
+= -= *= /= | ^
The same problem applies when the operands are a non-integer
enum and an int. Cast the enum to long or int respectively
to solve the problem.
IDE
- When debugging a mouse application the Options|Debugger|Display
Swapping option should be set to "Always" for best results.
- In the IDE, the mouse cursor is turned off during compilation
for performance improvements.
- To run or debug an overlaid application in the IDE when DOS
SHARE is loaded, the .EXE file must first be marked as
read-only. Otherwise, unload SHARE.
- Pressing Control-Break twice while running or stepping a
program from the IDE may cause unexpected results. In
particular, avoid pressing Control-Break twice in response
to any function requiring input (scanf, getch, etc.). To
break out of a program during such interaction, press
Control-Break and enter a valid input string. Control will
be returned to the IDE.
EXAMPLE PROGRAMS
- When you are running any example programs that come with .PRJ
files, if you didn't use the standard directories when you
installed Turbo C++ you will have to change the .PRJ file
to reflect your actual directory setup. Do this from inside
Turbo C++ with Alt-O/D.
LINKING C++ WITH C
- Linking C++ modules with C modules requires the use of a
linkage specification. Prototypes for C functions within C++
modules must be in one of the following forms:
extern "C" declaration
extern "C" { declarations }
For example, if a C module contains these functions:
char *SCopy(char*, char*);
void ClearScreen(void)
they must be declared in a C++ module in one of the
following ways:
extern "C" char *SCopy(char*, char*);
extern "C" void ClearScreen(void);
or
extern "C" {
char *SCopy(char*, char*);
void ClearScreen(void);
}
Failure to do so will result in "Undefined symbol" errors
during link. For further examples, see the standard header
files.
CLASS LIBRARY
- Two versions of the class libraries are provided; one that
includes debug information and one that does not. Small
versions of each are provided, and project files are
provided to build other models. Note that the non-debug
versions are used by default. If you would like to use the
debug version, copy it to the non-debug file. For instance,
in the CLASSLIB\LIB directory, copy TCLASDBS.LIB to
TCLASSS.LIB for the small model version.
- In some places the User's Guide incorrectly refers to the
online documentation for the Container Class Libraries as
CONTAIN.DOC. The correct file name is CLASSLIB.DOC, located
in the ..\DOC directory.
5. TESTING YOUR EXPANDED MEMORY: EMSTEST.COM
---------------------------------------------
Included with Turbo C++ is a program to test your Expanded
Memory hardware and software. If you have problems using
Turbo C++ with your EMS, type EMSTEST at the DOS prompt and
follow the instructions.
