Invocation commands

The classic invocation commands supported by IBM® XL C/C++ for Linux® 16.1.1 or earlier releases including xlc and xlC are not supported in IBM Open XL C/C++ for Linux on Power® 17.1.1. 

In IBM Open XL C/C++ for Linux on Power 17.1.1, use the ibm-clang, ibm-clang++, ibm-clang_r, and ibm-clang++_r invocation commands instead.
Note:
  • -pthread is not implied when the compiler is invoked by ibm-clang or ibm-clang++.
  • ibm-clang_r replaces xlc which is an invocation command in IBM XL C/C++ for Linux 16.1.1 or earlier releases. Similarly, ibm-clang++_r replaces xlC.
