| 3 | +--- |
| 4 | + |
| 5 | +Version 2.0.10 of the **esp32 board package** introduced a bug[^github-issue][^github-pr] that would cause compilation to fail for some Windows and Linux users. On Windows, the error output includes an `Access is denied` message. |
| 6 | + |
| 7 | +[^github-issue]: [Core Compilation failure on Linux in v2.0.10 #8424](https://github.com/espressif/arduino-esp32/issues/8424) |
| 8 | +[^github-pr]: [2.0.10 escaping fix #8433](https://github.com/espressif/arduino-esp32/pull/8433) |
| 9 | + |
| 10 | +The causes for the error are different depending on which system you're using: |
| 11 | + |
| 12 | +* [Windows](#windows) |
| 13 | +* [Linux](#linux) |

| 19 | +## If you're using Windows |
| 20 | + |
| 21 | +On Windows, the error output may look like this: |
| 22 | + |
| 23 | +``` |
| 24 | +Access is denied. |
| 25 | +cmd /c type nul > "C:\\Users\\Hannes" "Siebeneicher\\AppData\\Local\\Temp\\arduino\\sketches\\2B717D34C8CC4EA7678C7773DD033E96/file_opts" |
| 26 | +exit status 1 |
| 27 | +Compilation error: exit status 1 |
| 28 | +``` |
| 29 | + |
| 30 | +The issue is expected to be fixed in the next release of the esp32 board package. |
| 31 | + |
| 32 | +Meanwhile, you can try this solution: |
| 33 | + |
| 34 | +* Use <a class="link-download" href="https://downloads.arduino.cc/arduino-1.8.19-windows.exe">Arduino IDE 1.8.19</a> |
| 35 | +* Downgrade to **esp32 2.0.9**: |
| 36 | + * To make 2.0.9 and earlier versions available in the board manager, you need to add `https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json` as an ["Additional boards manager URL" in Preferences](https://support.arduino.cc/hc/en-us/articles/360016466340-Add-third-party-platforms-to-the-Boards-Manager-in-Arduino-IDE). |
| 37 | + * You cannot use the Nano ESP32 with this version. |

| 57 | + |
| 58 | +Meanwhile, you can try these solutions: |
| 59 | + |
| 60 | +* Use Arduino IDE 2.1.1 or later. |
| 61 | +* Use Arduino 1.8.19 downloaded as `.zip` download from the official <a class="link-up-right" href="https://www.arduino.cc/en/software#legacy-ide-18x">Downloads page</a>, instead of a package manager like `apt`. |
| 62 | +* Downgrade to **esp32 2.0.9**: |
