Building the Target

The following topic applies to Xcode*.
A single project can contain multiple targets. The active target determines how your project is built. This topic describes how to build the target using the Xcode* IDE and documents the build steps using the
xcodebuild
command line utility.
Starting with the 19.0 release of the Intel®
C++
Compiler,
macOS*
32-bit applications are no longer supported. If you want to compile 32-bit applications, you must use an earlier version of the compiler and you must use Xcode* 9.4 or earlier.

Building Using the Xcode* IDE

  1. Select the target in the project editor under
    Targets
    .
  2. Select
    Product
    Build
    .
  3. To view the results of your build, click the
    Log Navigator
    button.
You can change the compilation order of the files in an Xcode* target. To re-order the files listed under a target's
Compile Sources
, click a source file and drag it before, or after other compilations.

Building From the Command Line Using the xcodebuild Utility

You can use the
xcodebuild
utility to build a target. This utility uses the Xcode* project settings to build target projects from the command line. If you have previously configured your Xcode* project to build with the Intel compiler,
xcodebuild
invokes it from the command line.
To build from the command line:
  1. Check that the Xcode* project is configured to use the Intel®
    C++
    Compiler.
  2. Launch a terminal window from the finder by selecting
    Applications
    Utilities
    Terminal
    .
  3. Change directories to the directory containing the Xcode* project file (
    .xcodeproj
    ).
  4. If you have multiple versions of Xcode*, use the
    xcode-select
    utility to verify the current Xcode* version.
  5. Issue an
    xcodebuild
    command. For example:
    xcodebuild -project HelloWorld.xcodeproj -target HelloWorld -configuration Debug
  6. Run the program built in the example from the previous step by entering the following:
    ./build/Debug/HelloWorld
For more information, refer to the
xcodebuild
man page.
