This chapter provides instructions for setting up C++ application builds to use Coherence for C++.
The following sections are included in this chapter:
When integrating Coherence for C++ into your application's build process, it is important that certain compiler and linker settings be enabled. Some settings are optional, but still highly recommended.
Table 6-1 Compiler Settings for MSVC (Visual Studio)
| Setting | Build Type | Required? | Description |
|---|---|---|---|
|
/EHsc |
All |
Yes |
Enables C++ exception support |
|
/GR |
All |
Yes |
Enables C++ RTTI |
|
/O2 |
Release |
No |
Enables speed optimizations |
|
/MD |
Release |
Yes |
Link against multi-threaded DLLs |
|
/MDd |
Debug |
Yes |
Link against multi-threaded debug DLLs |
Coherence ships with a set of header files that uses the Coherence API and must be compiled with your application. The header files are available under the installation's include directory. The include directory must be part of your compiler's include search path.
Coherence for C++ ships with a release version of the Coherence library. This library is also suitable for linking with debug versions of application code. The library is located in the installation's lib directory. During linking, this directory must be part of your linkers library path.
During execution of a Coherence enabled application the Coherence for C++ shared library must be available from your application's library search path. This is achieved by adding the directory which contains the shared library to an operating system dependent environment variable. The installation includes libraries in its lib subdirectory.
Table 6-4 Name of the Coherence for C++ Library and Environment Variables
| Operating System | Environment Variable |
|---|---|
|
Windows |
PATH |
|
Solaris |
LD_LIBRARY_PATH |
|
Linux |
LD_LIBRARY_PATH |
|
Apple (Mac) OS X |
DYLD_LIBRARY_PATH |
For example, to set the PATH environment variable on Windows execute:
c:\coherence\coherence-cpp\examples> set PATH=%PATH%;c:\coherence\coherence-cpp\lib
As with the Java version of Coherence, the C++ version supports a concept of System Properties to override configuration defaults. System Properties in C++ are set by using standard operating system environment variables, and use the same names as their Java counterparts. The tangosol.coherence.cacheconfig system property specifies the location of the cache configuration file. You may also set the configuration location programmatically (CacheFactory::configure()) from application code, the examples however do not do this.
Table 6-5 Cache Configuration System Property Value for Various Operating Systems
| Operating System | System Property |
|---|---|
|
Windows |
tangosol.coherence.cacheconfig |
|
Linux |
TangosolCoherenceCacheConfig |
|
Solaris |
TangosolCoherenceCacheConfig |
|
Apple (Mac) OS X |
TangosolCoherenceCacheConfig |
Note:
Some operating system shells, such as the UNIX bash shell, do not support environment variables which include the '.' character. In this case, you may specify the name in camel case, where the first letter, and every letter following a '.' is capitalized. That is, "tangosol.coherence.cacheconfig" becomes "TangosolCoherenceCacheConfig".
For example, to set the configuration location on Windows execute:
c:\coherence\coherence-cpp\examples> set tangosol.coherence.cacheconfig=config\extend-cache-config.xml
Coherence for C++ requires no specialized deployment configuration. Simply link your application with the Coherence library. See the C++ examples included in the Coherence Examples for sample build scripts and configuration. The examples are included as part of the Coherence for Java distribution.
Note:
When deploying to Microsoft Windows the Visual Studio 2005 SP1 C++ run-time libraries are required. To build the samples, a version of Visual Studio 2005 SP1 or higher is required.
