Add IDF_PATH to User Profile¶

To preserve setting of IDF_PATH environment variable between system restarts, add it to the user profile, following instructions below.

Windows¶

The user profile scripts are contained in C:/msys32/etc/profile.d/ directory. They are executed every time you open an MSYS2 window.

Create a new script file in C:/msys32/etc/profile.d/ directory. Name it export_idf_path.sh.
Identify the path to ESP-IDF directory. It is specific to your system configuration and may look something like C:\msys32\home\user-name\esp\esp-idf
Add the export command to the script file, e.g.:
```
export IDF_PATH="C:/msys32/home/user-name/esp/esp-idf"
```
Remember to replace back-slashes with forward-slashes in the original Windows path.
Save the script file.
Close MSYS2 window and open it again. Check if IDF_PATH is set, by typing:
```
printenv IDF_PATH
```
The path previusly entered in the script file should be printed out.

If you do not like to have IDF_PATH set up permanently in user profile, you should enter it manually on opening of an MSYS2 window:

export IDF_PATH="C:/msys32/home/user-name/esp/esp-idf"

If you got here from section Setup Path to ESP-IDF, while installing s/w for ESP32 development, then go back to section Start a Project.

Set up IDF_PATH by adding the following line to ~/.profile file:

export IDF_PATH=~/esp/esp-idf

Log off and log in back to make this change effective.

Note

If you have /bin/bash set as login shell, and both .bash_profile and .profile exist, then update .bash_profile instead.

Run the following command to check if IDF_PATH is set:

printenv IDF_PATH

The path previously entered in ~/.profile file (or set manually) should be printed out.

If you do not like to have IDF_PATH set up permanently, you should enter it manually in terminal window on each restart or logout:

export IDF_PATH=~/esp/esp-idf

If you got here from section Setup Path to ESP-IDF, while installing s/w for ESP32 development, then go back to section Start a Project.
