Prerequisites ============= - libodb http://www.codesynthesis.com/products/odb/ - oci http://www.oracle.com/technetwork/database/database-technologies/instant-client/overview/index.html The OCI library can be obtained in two ways: as part of the Oracle database installation or as a separate distribution called Instant Client. If you have the Oracle database installed, then the OCI headers and libraries can be found in the following locations relative to ORACLE_HOME (root directory of the Oracle database installation): UNIX headers ORACLE_HOME/rdbms/public libraries ORACLE_HOME/lib Windows headers ORACLE_HOME\oci\include import libraries (.lib) ORACLE_HOME\oci\lib\msvc dynamic libraries (.dll) ORACLE_HOME\bin If you would like to use Instant Client, then in order to build the Oracle ODB runtime you will need the 'basic' and 'sdk' packages of the Instant Client distribution. If you are planning to run the ODB tests or examples, then you will also need the 'sqlplus' package. Once the Instant Client packages are unpacked, the OCI headers and libraries can be found in the following locations relative to the Instant Client root directory (referred to as instantclient_X_Y below): UNIX headers instantclient_X_Y/sdk/include libraries instantclient_X_Y Windows headers instantclient_X_Y\sdk\include import libraries (.lib) instantclient_X_Y\sdk\lib\msvc dynamic libraries (.dll) instantclient_X_Y In order for applications that are using OCI to be able to find the OCI libraries, when using either the Oracle database installation or Instant Client, make sure that: - on UNIX the 'libraries' directory is added to the LD_LIBRARY_PATH environment variable or the ld.so.conf file (or equivalent mechanisms for your platform); - on Windows the 'dynamic libraries' directory is added to the PATH environment variable. Building on UNIX ================ The following build instructions are for the Linux/UNIX/Mac OS X operating systems as well as for Cygwin and MinGW on Windows. The standard autotools-based build system is used on these platforms. After unpacking the source code archive, change to the libodb-oracle package directory (referred to as libodb-oracle/ from now on) and run the configure script: ./configure To see the available configuration options run configure with --help: ./configure --help The configure script expects the libodb headers and library to be installed in a directory where the C++ compiler and linker will search for them by default (normally /usr and /usr/local). If this library is installed in another directory, you can use the CPPFLAGS and LDFLAGS configure variables to specify its location, for example: ./configure CPPFLAGS=-I/opt/libodb/include LDFLAGS=-L/opt/libodb/lib If libodb is not installed and you would like to use its build directory instead, you can use the --with-libodb configure option to specify its location, for example: ./configure --with-libodb=/tmp/libodb While you can use the CPPFLAGS and LDFLAGS configure variables to specify the location of the OCI headers and libraries, the configure script provides the --with-oci option which can be used to specify the root directory either of the Oracle database installation (ORACLE_HOME) or of Instant Client (instantclient_X_Y). If the --with-oci option is not specified and OCI cannot be found using CPPFLAGS/LDFLAGS, then the configure script also checks if the ORACLE_HOME environment variable is set and if so, uses its value as the root of the Oracle database installation. As another example, the following configure command only builds shared libraries, uses the specified C++ compiler, and compiles with optimization and without debug information: ./configure --disable-static CXX=g++-4.5 CXXFLAGS=-O3 Once configuration is complete, run make to build libodb-oracle: make Once the build is completed successfully, you can install the libodb-oracle headers and libraries using the install target (you may need to do this step as root depending on the installation directory): make install Building on Windows =================== The following build instructions are for Windows using Microsoft Visual Studio. If you would like to build libodb-oracle with GCC either using Cygwin or MinGW, refer to the "Building on UNIX" section above. The standard Visual Studio project and solution files are used on this platform. The provided project files expect the libodb and OCI header and import library directories to be in the VC++ Directories Include and Library search lists. For libodb, see the INSTALL file in the package directory for more information on how to setup the VC++ Directories. For OCI, add the 'headers' directory mentioned in the Prerequisites section to the Include search list and the 'import libraries' directory to the Library search list. To build libodb-oracle, unpack the source code archive and open the libodb-oracle-vc<N>.sln file located in the libodb-oracle package directory (referred to as libodb-oracle\ from now on). Here <N> is the version of Visual Studio that you are using. Once the solution is open, select the desired build configuration (Debug or Release) and platform (Win32 or x64) and build the solution. The resulting 32-bit DLLs and import libraries are placed into the libodb-oracle\bin\ and libodb-oracle\lib\ directories, respectively. Similarly, the 64-bit DLLs and import libraries are placed into libodb-oracle\bin64\ and libodb-oracle\lib64\. The Release versions of the import libraries are named odb-oracle.lib and the Debug versions are named odb-oracle-d.lib. To configure Visual Studio to automatically locate the libodb-oracle headers, DLLs, and import libraries, add the following paths to your VC++ Directories: Win32: Include: ...\libodb-oracle Library: ...\libodb-oracle\lib Executable: ...\libodb-oracle\bin x64: Include: ...\libodb-oracle Library: ...\libodb-oracle\lib64 Executable: ...\libodb-oracle\bin64
