Legato 15-10 Build error


i tried to build legato on Ubuntu 14.04 an i get Bad Substitution error while Compiling legato-af for ar7.
I already checked if i’m using the linux bash.

Can anyone give me a hint how to fix this issue?

Thx, Rene

I solved the issue.

The Legato docs say “Run echo $0 to check your shell.” But this command returns the name of the current process. So the build process can open another shell which is not a bash.
You need to execute “$ sudo dpkg-reconfigure dash” on Ubuntu in all cases an answer the question with “NO”.

BR, Rene
