Building the Application

The
ipp_blur_rotate.cpp
 sample code has been developed for Intel® IPP installed within Intel® Parallel Studio XE. You can use the provided code, except for the graphical rendering part, as a starting point for your application that can be built within other product suites like Intel® System Studio.

Setting Up the Build Environment

Before you invoke the compiler component of the suite that you installed with Intel® IPP, you must set certain environment variables that define the location of compiler-related components. The Intel® C++ Compiler includes the
compilervars
 scripts that you can run to set environment variables:
  • On Windows*, you can find the
    compilervars.bat
     batch file at
    <install-dir>\compilers_and_libraries_<
    version
    >\windows\bin\
  • On Linux OS* and macOS*, you can find the
    compilervars.sh
     shell script at
    <install-dir>\compilers_and_libraries_<
    version
    >\<linux|mac>\bin\
For more information about setting environment variables for different product suites, refer to https://software.intel.com/en-us/articles/setting-up-the-build-environment-for-using-intel-c-or-fortran-compilers.

Compile and Link Your Code

To compile and link the code examples in this tutorial, do the following:
  • On Windows*:
    1. Unzip the
      ipp_blur_rotate_sample.zip
       archive downloaded from the Intel® Software Product Samples and Tutorials website.
    2. Run the Microsoft* Visual Studio* command prompt and change the directory to the
      Makefile
       location. By default,
      Makefile
       is located in the root of the
      ipp_blur_rotate_sample.zip
       archive.
    3. Run the
      nmake -f Makefile_win
       command.
  • On Linux* OS and macOS*:
    1. Unzip the
      ipp_blur_rotate_sample.tgz
       archive downloaded from the Intel® Software Product Samples and Tutorials website.
    2. Run the bash shell and change the directory to the
      Makefile
       location. By default,
      Makefile
       is located in the root of the
      ipp_blur_rotate_sample.tgz
       archive.
    3. Run the
      make -f Makefile_lin
       command on Linux* OS and
      make -f Makefile_mac
       on macOS*.
To run the application, run the following command from the directory where
Makefile
 resides:
  • On Windows*:
    ipp_blur_rotate.exe
  • On Linux*:
    ./ipp_blur_rotate
  • On macOS*:
    ./ipp_blur_rotate.app/Contents/MacOS/ipp_blur_rotate

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
