Tests for the IAR toolchains on CMake

The tests in this directory are for the CMake Modules for the IAR Toolchains (e.g., /path/to/share/cmake-x.xx/Modules/Compiler/IAR-*.cmake).

The run-tests.sh script will...

  • build one executable for each supported language (C, CXX and ASM) using...
  • the default CMake build configurations (Debug, Release, DebWithRelInfo and MinSizeRel).

Environment

The script was used with the following environments providing GNU Bash:

  • Cygwin (https://cygwin.com)
    • IAR Embedded Workbench
    • CMake for Windows
    • Ninja for Windows
  • MINGW64 (https://msys2.org)
    • IAR Embedded Workbench
    • CMake for Windows
    • Ninja for Windows
  • Ubuntu 20.04 (/WSL2)
    • IAR Build Tools for Linux
    • Cmake for Linux
    • Ninja for Linux

Environment variables

IAR_TOOL_ROOT

Export the $IAR_TOOL_ROOT environment variable, pointing to the top-level location in which all the IAR toolchains are installed. (Default: /opt/iarsystems)

Examples Effect
/c/IAR_Systems Perform tests on all toolchains found on the top-level directory.
/c/IAR_Systems/EW/ARM Perform tests only using the toolchains found in the ARM directory.
/c/IAR_Systems/EW/ARM/[7-9]* Perform tests on "Embedded Workbench for Arm" from V7 to V9.
/c/IAR_Systems/EW/ARM/9.30.1 Perform tests only using "Embedded Workbench 9.30.1".

IAR_LMS2_SERVER_IP (optional)

Export the IAR_LMS2_SERVER_IP environment variable pointing to the license server, if the client's 1st-time license setup is required. Applies to the -GL and -NW products. (Default: not set)

CMAKE_GENERATOR (optional)

Export the CMAKE_GENERATOR environment variable to specify which generator to use. (Default: Ninja Multi-Config)

MSYSTEM

This environment variable is automatically set by MSYS2, MINGW64 and MINGW32. Cygwin users must set it manually.

Example: export MSYSTEM=CYGWIN

Examples

Using MINGW64

The example below will test every tool found in C:\IAR_Systems\EW using MINGW64:

export IAR_TOOL_ROOT=/c/IAR_Systems/EW
# Extracted from a zip archive
export PATH=/c/cmake-3.25.0-x86_64/bin:$PATH
git clone https://github.com/iarsystems/cmake-tutorial ~
cd ~/cmake-tutorial/tests
./run-tests.sh

Using Ubuntu (/WSL2)

The example below will test every tool found in /opt/iarsystems using Ubuntu (WSL2):

git clone https://github.com/iarsystems/cmake-tutorial ~
cd ~/cmake-tutorial/tests
./run-tests.sh

Using Cygwin

The example below will test every tool found in C:\IAR_Systems\EW using Cygwin:

export IAR_TOOL_ROOT=/cygdrive/c/IAR_Systems/EW
# Only required by Cygwin
export MSYSTEM=CYGWIN
# Extracted from a zip archive
export PATH=/cygdrive/c/cmake-3.25.0-x86_64/bin:$PATH
git clone https://github.com/iarsystems/cmake-tutorial ~
cd ~/cmake-tutorial/tests
./run-tests.sh
