Compile Error in Xreg GraphGen using Docker

[m-baader]

Hi all,

I cannot compile GraphGen inside Docker, due to an error: 'shared_ptr' is not a member of 'std'.

Here is the transcript of everything I did:

$ docker run -it therealcaoyudong/qtorch

Is there a quick fix for this?

Hello - unfortunately, I don't think that docker container is maintained. If you clone the git repo, go into the XregGraphGen folder, then run make all, it should compile to a binary called main, which you should be able to run with ./main <args>. I was able to do this just now

Hi, thanks for the quick reply. This worked!
