This produced two assembly files named "test.s" and "testMIC.s". Then I compile it to assembly file using the command "icc -S test.c". I write a C file named "test.c", which contains offload operation on mic.
The above workaround can do by not setting LIBRARY_PATH to contain the Intel specific directories in the vars files for the product, since the driver should be able to find this information. Any external setting of values like LIBRARY_PATH take precedence over internal settings done by the driver. Intel64 specific directory is being added to LIBRARY_PATH in the vars scripts. The Intel compiler driver automatically sets the Intel specific library directory depending on target architecture as long as the compiler is run from an expected installed directory structure. $ icc qa.cpp -static -gcc-name=/opt/gcc/gcc-4.8.1/bin/g++ -m32 //This would compiles successfully without linking warnings and linkage abortion.

Click here to find and download 01.org Projects' files! See allīug tracking allows the developers to have a record of the bugs and issues found in an application for a more efficient way to fix them. Github repositories are the most preferred way to store and share a Project's source files for its easy way to navigate repos. A more direct channel to solve your questions and help others to get involved. See allĪ mailing list improves communication for all the people interested in a 01.org Project: developers, final users and contributors. This establishes a clear link between 01 and the project, and help to have a stronger presence in all Internet. To provide more information about a Project, an external dedicated Website is created.
