About registering a new compiler toolchain

You can use a different compiler toolchain other than the one installed with DS-5.

If you want to build projects using a toolchain that is not installed with DS-5, you must first register the toolchain you want to use. You can register toolchains:

  • Using the Preferences dialog in Eclipse for DS-5.
  • Using the add_toolchain utility from the DS-5 Command Prompt.

You might want to register a compiler toolchain if:

  • You upgrade your version of DS-5 but you want to use an earlier version of the toolchain that was previously installed.
  • You install a newer version or older version of the toolchain without re-installing DS-5.

When you register a toolchain, the toolchain is available for new and existing projects in DS-5.


You can only register Arm® or GCC toolchains.
