Installation fails at libtool

[axibo-reiner]

Built as per instructions

lib tool commonly has a problem with whitespace. Ensured there where no whitespace in the directory paths. Built with both the install script and manually.

Error

Were you able to resolve this? I am having the same issue.
It works on Ubuntu 18 with Kernel 4.15, but anything later than that I get this error.
