Errors building app on Windows

[Agent-E11]

I am trying to build my Fyne app on Windows, using Msys2. I had previously installed gcc using MinGW, but that gave me a bunch of errors, so I decided to follow the official tutorial. I followed the the Windows tutorial, but when I run go run fyne.io/fyne/v2/cmd/fyne_demo@latest, I get the following errors:

collect2.exe: error: ld returned 1 exit status

These are the same errors I got when I tried building using gcc from MinGW, except the paths to the executables have changed.

This means that you have a 32bit toolchain somewhere in your system. There is a mix of 64 and 32bit somehow.

Or it could be that the error was caused earlier and that you fixed the tooling but did not reset the caches from before...

I didn't know that the MSYS2 64 terminal was required (I haven't used MSYS before, so I assumed that it would be the same problem as WSL). I tried running go run fyne.io/fyne/v2/cmd/fyne_demo@latest in MSYS2 64, and it worked. Building and running my own app from MSYS2 64 also worked.

So, there must be a problem with running it in Powershell. I have already updated the $Env:Path variable using the method described in the tutorial, so I am not sure what the problem could be.

[andydotxyz]

I am not sure either, but I would guess that other environment is not correct, or that you need to reboot for some changes to take effect.
As the app is compiling I'm tempted to close this, as we don't have any docs or recommendations for making PowerShell work.

[Agent-E11]

Ok, thanks. I have rebooted my computer, but it is still not compiling.

[Agent-E11]

I have just resolved it 🤣
At the top of the error message, it says

C:\Program Files (x86)\Go\pkg\tool\windows_386\link.exe: running gcc failed: exit status 1

It is going to the Program Files (x86) folder for the go installation. So I renamed the files in C:\Program Files (x86)\Go\bin (go.exe -> go_32.exe, gofmt.exe -> gofmt_32.exe) and it worked (I have already installed a 64bit version in C:\Program Files\Go)

[andydotxyz]

Yeah, looks like somehow Go installer thought it was a 32bit app
