@venlx Did the ninja-build package install gn? Did it install it somewhere in your PATH?

@bzbarsky-apple I have the same problem on my pi 4. Ninja-build did add nothing to PATH and gn is not found.
But I read in the raspi install instruction that you recommend ubuntu server as an OS. My pi has the latest raspberry OS (debian bullseye) installed. Do you know if there are any packages that need to be installed extra?

Edit: So you need to built gn by yourself and add the gn/out directory to PATH. It is not pre-built for debian.
But after doing that, I get problems with ninja.

I'm a little surprised bootstrap requires gn, since one of its jobs is to install the cipd gn (and then activate adds that to the PATH)... @mspang do you know how this is supposed to work?

[phbasler]

@bzbarsky-apple Are there any updates on this? Or do you have an idea how one could set up a workaround for this?

I've been stuck here for a long time.
How to solve this problem.

[bzbarsky-apple]

I have no idea. If I knew, I would have said up above. You need to get the attention of someone who knows how bootstrap/activate are supposed to work... @andy31415

I got a tip on discord and tested it with a 64bit raspberry os lite. There it works without a problem. On my previous test I still had a 32 bit Raspberry OS.
