Hello, I am new here.
Since the update I can't compile ESP32 anymore.

Error message: (in German)

Zugriff verweigert

exit status 1

Compilation error: exit status 1

I installed the IDE2.1.1 on another computer and created a new sketch. The same problem appears.

the output is:

exit status 1

Compilation error: exit status 1

I installed the software on a virtual machine for testing. In the board manager ESP32 by Espressif installed, the ESP32 Dev Module selected. The same problems occur.

The Error is a space in my Username.

The compiler writes:

cmd /c type nul > "C:\Users\Michael" "Glier\AppData\Local\Temp\arduino\sketches\925B853CE76FCD073FEC76814EEE6C3C/file_opts"

but correct its (i think so):

cmd /c type nul > "C:\Users\Michael Glier\AppData\Local\Temp\arduino\sketches\925B853CE76FCD073FEC76814EEE6C3C/file_opts"

How i can modify it?

Thank you.

Do I have any change to fix the problem?
I think I am not the only one with spaces in the username.

Before the update of Arduino IDE I had no problem.

The problem is with the new updated board manager 2.0.10 of esp32 which throws error. I fixed it by pasting " https://dl.espressif.com/dl/package_esp32_index.json " in the Additional Boards section in preferences and changing it to 1.0.6.

It took me 5 hours to figure out the issue. Hopefully the bug gets fixed, till then use earlier version 1.0.6 of esp32

I fixed it by pasting " https://dl.espressif.com/dl/package_esp32_index.json " in the Additional Boards section in preferences and changing it to 1.0.6.

Your fix is far in excess of what is necessary. The regression was introduced in the 2.0.10 release, so you can simply roll back to the previous version (2.0.9) instead of going all the way back to the antiquated 1.0.6.

Even if you did want to use 1.0.6 for some reason, it is not necessary to change your " Additional Boards Manager URLs " preference in order to accomplish that. All the releases are available from the maintained URL specified in the official installation instructions for the " esp32 " boards platform:

https://docs.espressif.com/projects/arduino-esp32/en/latest/installing.html#installing-using-arduino-ide

You can simply select the version you want from the menu in the Arduino IDE Boards Manager.

Hopefully the bug gets fixed

It has already been fixed:

If you want the fix now, you can apply it manually to your existing installation. I can provide instructions for doing that if anyone is interested.

OK, I have spent most of the day chasing what appears to be this "space in user name" fiasco.
I have uninstalled, reinstalled, all the usual Windows stuff. Rebooted, etc. version 1.18 worked OK.
Moving back to 2.0.9 solved the "access is denied problem. Now, I can get back to rebuilding everything I destroyed along the way. My big mistake--accepting an "upgrade". One of those things--I had just made some changes, then accepted the upgrade. Assumed it was something I did. Which is usually the case.

"If you want the fix now, you can apply it manually to your existing installation. I can provide instructions for doing that if anyone is interested.".

Count me as one who would like said instructions. I do like to keep stuff up to date.

Pardon my grumpy tone. This forum and this topic brought me back from the edge of self diagnosed insanity. Thanks.

OK, here you go:

Using board 'esp32' from platform in folder: C:\Users\per\AppData\Local\Arduino15\packages\esp32\hardware\esp32\2.0.10
Use any text editor to open the file platform.txt that you find under the path shown in that line of the compilation output.
Change line 192 of platform.txt from this:
recipe.hooks.core.prebuild.set_core_build_flag.pattern=bash -c "echo '-DARDUINO_CORE_BUILD' > {file_opts.path}"
to this:
recipe.hooks.core.prebuild.set_core_build_flag.pattern=bash -c "echo -DARDUINO_CORE_BUILD > {file_opts.path}"
Change lines 195-197 from this:
recipe.hooks.prebuild.set_core_build_flag.pattern.windows=cmd /c type nul > {file_opts.path}
recipe.hooks.core.prebuild.set_core_build_flag.pattern.windows=cmd /c echo "-DARDUINO_CORE_BUILD" > {file_opts.path}
recipe.hooks.core.postbuild.set_core_build_flag.pattern.windows=cmd /c type nul > {file_opts.path}
to this:
recipe.hooks.prebuild.set_core_build_flag.pattern.windows=cmd /c type nul > "{file_opts.path}"
recipe.hooks.core.prebuild.set_core_build_flag.pattern.windows=cmd /c echo "-DARDUINO_CORE_BUILD" > "{file_opts.path}"
recipe.hooks.core.postbuild.set_core_build_flag.pattern.windows=cmd /c type nul > "{file_opts.path}"
Save the file.
Select File > Quit from the Arduino IDE menus.
Start Arduino IDE.

ⓘ Restarting Arduino IDE is necessary to cause it to recognize the changes you made to the platform.txt file.
Now try compiling your sketch for an ESP32 board again. Hopefully this time the "Access is denied" error  will no longer occur.
