Issues with setting up development environment : mingw32/msys

[c.Hicham]

Hello everyone,

I'm trying to reinstall esp32 development environment for my work computer in windows 10 using this link :
https://docs.espressif.com/projects/esp ... setup.html

Few months ago I was able to make it work, make projects, flash them to esp32 board... happy life . until I run of some issues and decided to remove msys folder to restart the setup from scratch.

After extracting the esp32 toolchain and getting the msys folder, I follow the steps to download the esp-idf repository and update it, checkout branch v3.3 and synchronize the submodules...etc.
When I run tools/windows/windows_install_prerequisites.sh
I get the following output :

Code: Select all

1-The first thing that I find weird is the conflict with catgets I. I tried the setup in my personal computer and didn't get this conflict.
from my understanding all the packages, dependencies are checked inside the msys folder, that's the hole idea behind having this kind of environment, right ? Please, correct me if I'm wrong.
Can anyone care to explain why I have this conflict in certain computer and not in another even if i'm running in both windows 10 ?

The problem is coming from pacman upgrade command : pacman -Syu.
I delete catgets and use the command pacman -Syu . Below are the logs :

warning: terminate MSYS2 without returning to shell and check for updates again
warning: for example close your terminal window instead of calling exit

I follow the suggestion on the last 2 warning messages of the installer and close the msys window but the program doesn't response anymore and the only solution is to close it from the Task Manager.
I open mingw32.exe again and run pacmac -Syu but I get the locked database error :

Code: Select all

pacman -Suy
:: Synchronizing package databases...
error: failed to update mingw32 (unable to lock database)
error: failed to update mingw64 (unable to lock database)
error: failed to update msys (unable to lock database)
error: failed to synchronize all databases

As suggested in many discussions I delete the /var/lib/pacman/db.lck file which is a 0 kb file and run again pacman -Suy but the same error appear again and again.
I restart my computer and try again but yet the same error.

-I tried the same installation in another work computer that has the same configuration, antivirus and firewall...etc and got the same results, no luck !
-I tried it in my personal computer and everything worked just fine.
-I tried to just upgrade the msys with pacman -Syu without getting esp-idf repository yet got the same error

Now when I run pacman -Syu it crashes in the following :

Code: Select all

:: Synchronizing package databases...

With pacman -Syuu it gets further

Code: Select all

pacman -Syuyuu
:: Synchronizing package databases...
error: failed to update mingw32 (unable to lock database)
error: failed to update mingw64 (unable to lock database)
error: failed to update msys (unable to lock database)
error: failed to synchronize all databases

I would appreciate it if anyone can give me some suggestions or explanation of this issue so I can fix it!

Thank you guys.
