Syntax error while building proton

[kiangribi]

Proton Version: commit 80d7014 (HEAD -> proton_5.0, tag: proton-5.0-5b

I tried to install proton on my Ubuntu 19.10. The steam runtime was installed successfully but the compilation of proton failed. I am using fish shell but I tried to execute it in a bash environment and it still didn't work.

I followed the build instructions as follows

• Dependencies installed
• Repo cloned
• Steam runtime installed

$ docker images

That error is occurring when trying to generate the configure script for vkd3d. Do you have libtool installed?

[kiangribi]

This error occurs when I try to build the package with make. Yes, I got another error before, that basically said I should install libtool and so I did it.
