3. Compilation

3.1. Unix systems

For Unix systems, RTI Perftest makes use of a script in the top level directory named build.sh.

The purpose of build.sh is to, first, invoke RTI DDS Generator (rtiddsgen) in order to generate the type-code files and makefiles needed to compile a target architecture; then, second, execute the makefile with the right arguments to generate the executables.

This script supports the code generation and compilation for Traditional C++, Modern C++ and Java.

Potentially, build.sh can generate and compile code for every architecture supported by rtiddsgen where a makefile is generated as output when the -example command-line is specified.

3.1.1. Prerequisites

  • RTI Connext DDS Professional or RTI Connext DDS Micro should be installed in the system where the build.sh script is going to run. The Target libraries for the platform to be generated should also be installed.

  • The $NDDSHOME environment variable should be set correctly. Alternatively, $NDDSHOME can be passed directly to the build.sh script by using the --nddshome <PATH> command-line option.

    When compiling for RTI Connext DDS Micro, the $RTIMEHOME environment variable should be set correctly. Alternatively, $RTIMEHOME can be passed directly to the build.sh script by using the --rtimehome <PATH> command-line option.

  • The build.sh script is written in bash. It is going to try to execute it from /bin/bash.

  • GNU make is required to be accessible from the $PATH environment variable in order to execute the makefiles generated by rtiddsgen. Alternatively the GNU make executable can be passed directly to the build.sh script by using the --make <PATH> command-line option.

  • When compiling for RTI Connext DDS Micro, Cmake is required to be accessible from the $PATH environment variable in order to execute the makefiles generated by rtiddsgen. Alternatively the cmake executable can be passed directly to the build.sh script by using the --cmake <PATH> command-line option.

  • The C++ Compiler/Linker parent folders should be in the $PATH variable, or they should be specified as full path names (see parameters below). If unspecified, the names of the compiler and linker are going to be determined by the makefile generated by rtiddsgen. The C++ Compiler and Linker are not required if the script is set to avoid the C++ compilation by adding the --skip-cpp-build and --skip-cpp03-build command-line options.

  • Java JDK should be available in the system and accessible from the $PATH environment. This is not required if the script is set to avoid the Java ByteCode generation by adding the --skip-java-build command-line option.

  • If you intend to compile and test using RTI Security Plugins, you will need to link against the OpenSSL libraries for your architecture.

    ./build.sh --platform x64Darwin15clang7.0
    
  • Generation and compilation for a given architecture (x64Darwin15clang7.0) just for C++ (traditional and modern).

    ./build.sh --platform x64Darwin15clang7.0 --skip-java-build
    
  • Generation and compilation for a single given architecture (x64Darwin15clang7.0) just for java.

    ./build.sh --platform x64Darwin15clang7.0 --java-build
    
  • Generation and compilation for a given architecture (x64Darwin15clang7.0) for all supported languages and linking against the Dynamic + Debug libraries.

  • Generation and compilation for a given architecture (x64Darwin15clang7.0) for all supported languages, enabling the security options and linking dynamically. As you can see in this case, there is no need to specify the --openssl-home command-line argument.

  • Generation and cross-compilation for a non-native architecture (armv8Linux4.4gcc5.4.0). Note how you can specify the Compiler/Linker used by rtiddsgen.

  • RTI Perftest directory clean-up.

    ./build.sh --clean
    

3.1.4. Note: Build script execution for VxWorks kernel mode

After building the RTI Perftest executables for VxWorks kernel mode, an extra step is needed: “Munching.” Munching is automatically done in RTI Connext DDS Professional starting in 6.0.0. However, for previous versions and for RTI Connext DDS Micro, the process has to be done manually.

3.2. Windows systems

For Windows systems, RTI Perftest makes use of a script in the top level directory named build.bat. Its content is equivalent to the build.sh described before.

The purpose of build.bat is to invoke RTI DDS Generator (rtiddsgen) in order to generate the type-code files and Visual Studio solution needed to compile a target architecture. Then execute the Visual Studio solution with the right arguments to generate the executables.

This script supports the code generation and compilation for Traditional C++, Modern C++, C# and Java.

The build.bat script should be able to generate and compile code for every Windows architecture supported by rtiddsgen when the -example command-line is specified.

3.2.1. Prerequisites

  • RTI Connext DDS should be installed in the system where the build.bat script is going to run. The Target libraries for the platform to be generated should also be installed.

  • The %NDDSHOME% environment variable should be set correctly. Alternatively, %NDDSHOME% can be passed directly to the build.bat script by using the --nddshome <PATH> command-line option.

    When compiling for RTI Connext DDS Micro, the %RTIMEHOME% environment variable should be set correctly. Alternatively, %RTIMEHOME% can be passed directly to the build.bat script by using the --rtimehome <PATH> command-line option.

  • The Microsoft Visual Studio for the architecture intended to be built should be installed in your system. The msbuild.exe program should be available in the %PATH% variable. [See note-1]

  • When compiling for RTI Connext DDS Micro Cmake is required to be accessible from the %PATH% environment variable in order to execute the makefiles generated by rtiddsgen. Alternatively the cmake executable can be passed directly to the build.bat script by using the --cmake <PATH> command-line option.

  • Java JDK should be available in the system and accessible from the %PATH% environment. This is not required if the script is set to avoid the Java ByteCode generation by adding the --skip-java-build command-line option.

  • If you intend to compile and test using RTI Security Plugins, you will need to link against the OpenSSL libraries for your architecture.

[note-1]: The simplest way to run the build.bat script and ensure that all the Microsoft Visual Studio variables are correctly set is by running it from the Visual Studio Command Prompt provided by each of the Microsoft Visual Studio versions.
