Working with multiple toolchain versions

Introduction

When multiple toolchain versions are used with the same CMake project, the following method can be used.

Applies to

• CMake projects using multiple versions of the IAR C/C++ Compilers.

Tasks

• Create one <your-iar-toolchain-file>.cmake per toolchain, each one with its appropriate settings. Example:

bxarm-9.50.1.cmake
bxarm-8.50.6.cmake

• When configuring the CMake project, use -B to select which build directory will be used for each toolchain. Example, when executing from the project's top directory:

cmake -G Ninja -Bbuild-9.50.1 --toolchain /path/to/bxarm-9.50.1.cmake
cmake -G Ninja -Bbuild-8.50.6 --toolchain /path/to/bxarm-8.50.6.cmake

• Build each output individually

cmake --build build-9.50.1
cmake --build build-8.50.6
