Installing error
Closed this issue · 8 comments
Hi,
I dont have much experience in golang so maybe it could be a strange question. I am getting following error when I try to install package using
go get github/.com/Kagami/go-face
command.
github.com/Kagami/go-face

Any idea?
What version of compiler do you use? For GCC it should be 7+
Hi,
I have similar problem.
go get github.com/Kagami/go-face
command.

Hm, maybe it's actually 7.3+. It builds on travis with gcc 7.3.0 without issues.
After gcc 7.3 have install, i get this error now :
go get github.com/Kagami/go-face
command.

How did you install dlib package? From the PPA?
From the PPA yes
Hi again, sorry for late response. I use virtualbox for my development environment and some packages on this box can be too old. I checked gcc version as you mentioned and it was 5.4.0. I've upgraded to 7.3.0 and the error message gone away.
Thanks.
Thanks.
@pacpacpacpacpacpac could you please create separate issue for that? I don't think it's related.
