1 TTClasses Development Environment

Set UNIX environment variables

To use TTClasses, ensure that your shell environment variables are set correctly through the appropriate ttenv script . See "Environment variables" in the Oracle TimesTen In-Memory Database Installation Guide for details.

Instead of doing this directly, you can add a line for the appropriate script to your login initialization script (for example, .profile or .cshrc).

Compile TTClasses on UNIX

If you have application linking problems, which can be caused by using a different C++ runtime than what TTClasses was compiled with, recompile the library using the make utility.

To recompile TTClasses, change to the ttclasses directory, where install_dir is your TimesTen installation directory:

$ cd install_dir/ttclasses

Run make clean for a fresh start:

$ make clean

Recompile TTClasses for direct connections as follows:

$ make

To recompile TTClasses for client/server connections, use the MakefileCS Makefile:

$ make -f MakefileCS

Compilation options on UNIX

The following make target options are available when you compile TTClasses in a UNIX environment:

• all: Build a shared optimized library or libraries (default). Use this with Makefile for direct connections, or with MakefileCS for client/server connections.

• shared_opt: Build a shared optimized library. Currently this has the same effect as all.

• shared_debug: Build a shared debug library.

• static_opt: Build a static optimized library.

• static_debug: Build a static debug library.

• opt: Build the optimized libraries (shared and static).

• debug: Build the debug libraries (shared and static).

• clean: Delete the TTClasses libraries and object files.

To specify a make target, use the name of the make target on the command line.

For example, to build a shared debug version of TTClasses:

$ make clean shared_debug

Install TTClasses after compilation (UNIX only)

After compilation, install the library so all users of the TimesTen instance can use TTClasses. The following shows the steps to install the TTClasses library on a UNIX system.

$ cd install_dir/ttclasses
$ make install

Set Windows environment variables

Before recompiling, ensure that the PATH, INCLUDE, and LIB environment variables point to the correct Visual Studio directories. Execute the applicable Visual Studio C++ batch file (for example, VCVARS32.BAT or VSVARS32.BAT) to accomplish this.

Then set environment variables for TimesTen (if they were not already set during installation) by running the following:

install_dir\bin\ttenv.bat

Compile TTClasses on Windows

If you have application linking problems, which can be caused by using a different C++ runtime than what TTClasses was compiled with, recompile the library using the nmake utility.

To recompile TTClasses, change to the ttclasses directory, where install_dir is your TimesTen installation directory:

install_dir\ttclasses

Run nmake clean for a fresh start:

install_dir\ttclasses> nmake clean

Then recompile. By default this is for both direct and client/server connections:

install_dir\ttclasses> nmake

Compilation options on Windows

The following make target options are available when you compile TTClasses in a Windows environment.

• all: Build shared optimized libraries for direct and client/server connections (default).

• client: Build shared optimized library for client/server only.

• msdm: Build shared optimized library for Microsoft driver manager.

• clean: Delete the TTClasses libraries and object files.

To specify a make target, use the name of the make target on the command line.

For example, to build only the client/server TTClasses library:

install_dir\ttclasses> nmake clean client

TTEXCEPT: Throw C++ exceptions

Compile TTClasses, as well as your applications, with the -DTTEXCEPT flag to make TTClasses throw C++ exceptions. (TTClasses is compiled this way by default.) Put {try/catch} blocks around all TTClasses function calls and catch exceptions of type TTStatus.

An alternative, although discouraged, mode of operation is to compile TTClasses and your application without TTEXCEPT enabled. In this mode, error handling is accomplished using older method versions with an explicit TTStatus& parameter, as in earlier TimesTen releases.

See "TTStatus".

TTC_USE_STRINGSTREAM, USE_OLD_CPP_STREAMS: For C++ I/O streams

There are multiple types of C++ streams and they are not compatible with each other. TimesTen provides two related flags. Which streams you use in your application determines which flag to set, or whether you should set neither, as follows (from newer stream types to older):

• For streams where you are including <iostream> and using the ostringstream class, set the TTC_USE_STRINGSTREAM flag.

• For streams where you are including <iostream> and using the ostrstream class, set neither flag. This is the default for most platforms and compilers.

• For streams where you are including <iostream.h> and using the ostrstream class, set the USE_OLD_CPP_STREAMS flag. This is the default for some older platforms and compilers.

Check your TTClasses Makefile. If the flags are not set properly, then update the Makefile as appropriate, recompile TTClasses, and replace the previous TTClasses library file with the recompiled one.

Also see the subsections that follow.

TTDEBUG: Generate additional debugging and error checking logic

Compile TTClasses with -DTTDEBUG to generate extra debugging information. This extra information reduces performance somewhat, so use this flag only in development (not production) systems.

TT_64BIT: Use TTClasses with 64-bit TimesTen

Compile TTClasses with -DTT_64BIT if you are writing a 64-bit TimesTen application.

Platform-specific compiler macros

The following compiler macros are specific to a particular platform or compiler combination. You should not have to specify these compiler macros manually. Their use is determined by the Makefile chosen by the configure program.

• gcc: Compile TTClasses with the -DGCC flag when using gcc on any platform.
