Compilation on Ubuntu failing: cask not found

[Nicholas-Autio-Mitchell]

I got an error, which I have never had before on Ubuntu (I couldn't figure out a root cause), which I solved. Cask was not being found, so I had to install it as per the official Cask website, running:

$ curl -fsSL https://raw.githubusercontent.com/cask/cask/master/go | python

Here was the error I was getting:

$ make -s
Using Emacs 25.3 
make: cask: Command not found
Makefile:44: recipe for target '.cask/25.3' failed
make: *** [.cask/25.3] Error 127

Here are the relevant lines in Makefile:

42# Init cask                                                                                                                                        
43.cask/$(emacs_version):
44        cask install

The Cask file is in the cloned repository and all stated dependencies are met. This didn't happen on the same Ubuntu 16.04 system about 6 months back.

Five months later and I am getting the same issue as described above, but this time my fix isn't working.
I can make the cask command work by explicitly adding it's bin folder to my PATH, but now I get a different error:

config.status: creating config.h
config.status: config.h is unchanged
ar: `u' modifier ignored since `D' is the default (see `U')

I am getting the exact same error too. Anyone found a fix?

[CaptainTux]

same here.

Looks like this cask issue is responsible.

i am using arch linux and installed cask via AUR.
and it did not help, but i found a workaround by just installing via melpa.
all i needed to do was M-x package-refresh-contents and then M-x package-install pdf-tools.
not sure if that's the best way but worked for me

@nicholas-mitchell if you're on ArchLinux, use cask-git package instead of cask. It will solve the problem

[berkay-repos]

Installing cask from the git repository fixed it for me.
$ curl -fsSL https://raw.githubusercontent.com/cask/cask/master/go | python

I'm on Ubuntu 20.04 and the suggested fixes didn't work. This did work:

wget -O getcask raw.githubusercontent.com/cask/cask/master/go
python getcask
export PATH="~/.cask/bin:$PATH"
make -s
