The following Clang compilers are supported:


Clang C/C++ Compiler v 3.9

  • Compiler acronym: clang_3_9
  • Host OS: Linux
  • Supported languages: C89, C99, C++98, C++11, C++14
  • Supported practices: Full support
  • Support level: Standard

Additional Notes 

  • Only the x86_64 target has been tested. If the clang 3.9 compiler is built as a multi-target compiler, C/C++test code analysis may not function as expected on cross-compilation targets.
  • The pre-built cpptest runtime is not supported for dynamic analysis (unit testing and application monitoring). The runtime must be built during the execution of the test configuration by setting autoBuildDefault="true" in the test execution flow.
  • The xmm intrinsic headers are not supported for dynamic analysis.

  • Clang is used to link inside of C/C++test by default. If errors occur during linking that relate to missing C/C++ libraries, then change the linker in the Build Settings from clang to clang++.

  • The clang_3_9 compiler configuration does not use the default GCC for selecting headers. As a result, problems can occur during compilation of instrumented source code during unit testing and application monitoring.

Clang C/C++ Compiler v 4.0

  • Compiler acronym: clang_4_0
  • Host OS: Linux
  • Supported languages: C89, C99, C++, C++11, C++14, GNU++11, GNU++14
  • Supported practices: Full support
  • Support level: Standard

Additional Notes

  • C/C++test does not support C++17 features accepted by clang
  • Only the x86_64 target has been tested. If the clang 4.0 compiler is built as a multi-target compiler, C/C++test code analysis may not function as expected on cross-compilation targets.

Clang C/C++ Compiler v 5.0

  • Compiler acronym: clang_5_0
  • Host OS: Linux
  • Supported languages: C89, C++11, C++14
  • Supported practices: Full support
  • Support level: Standard

Additional Notes

  • By default, clang is used to link inside of C++test. If errors occur during linking that relate to missing c++ libraries, then change the linker in the build settings from clang to clang++.
  • Only the x86_64 target has been tested. If the clang 5.0 compiler is built as a multi-target compiler, C/C++test code analysis may not function as expected on cross-compilation targets.
  • C++17 is not currently supported.
  • The avx512 intrinsic headers are not supported
  • This version has been tested with GCC 6 and newer. Pairing this compiler with older versions of GCC is unsupported.

Clang C/C++ Compiler v 6.0

  • Compiler acronym: clang_6_0
  • Host OS: Linux
  • Supported languages: C89, C99, C++98, C++11, C++14, C++17
  • Supported practices: Full support
  • Support level: Standard

Additional Notes

  • The avx2 intrinsic headers are not supported.
  • The avx512 intrinsic headers are not supported
  • This version has been tested with GCC 6 and newer. Pairing this compiler with older versions of GCC is unsupported.

Clang C/C++ Compiler v 8.0 (x86_64)

  • Compiler acronym: clang_8_0
  • Host OS: Linux
  • Supported languages: C++98, C++11,C++14,C++17, C89, C99, C11
  • Supported practices: static analysis
  • Support level: Standard

Additional Notes

  • C++20 features are not supported.
  • Clang is a multitarget compiler. This configuration only supports the x86_64 architecture and is not suitable for any other target.
  • This version has been tested with the clang target x86_64-linux-gnu.

About Support Levels

  • Extended: Support has been validated with extended testing and is approved for use in safety-critical software development.
  • Standard: Support has been validated with standard testing and is approved for use in non-safety critical software development.
