Building dart sdk

[MuAladdinIbrahim]

I'm trying to install dart sdk on fedora 29. when I comes with ./tools/build.py --mode release --arch x64 create_sdk step .. the output is

ninja -C out/ReleaseX64 create_sdk
ninja: Entering directory `out/ReleaseX64'
ninja: error: loading 'build.ninja': No such file or directory
BUILD FAILED

So what I can do? I checked permissions and checked that "build.ninja" is in ReleasseX64 directory.

Can you try to run it in verbose mode?

./tools/build.py --verbose --mode release --arch x64 create_sdk

Maybe the gn did not ran successfully and the ninja files were not generated, or do they exist?

[MuAladdinIbrahim]

@sassman I tried it and the same error occurs. yes they exist.

I found this answer but actually I can't do as he said.

Okay apparently using /opt/depot_tools/ninja is what causes the error. Use the /usr/bin/ninja bundled with the project makes it work.

@MuhammadAlaeldin can you check if your distro ships ninja out of the box? If so you could e.g. symlink /opt/depot_tools/ninja to the distributors one, or just remove it from the dept_tools folder.

@sassman It doesn't work too :/ thanks for your help anyway. at all I'm not good with linux so this is a big problem to me.

@MuhammadAlaeldin I was able to reproduce it and got this error:

It can be reproduced with the Dockerfile
