make: cuda_djezo.cpp:65:55: error: ‘to_string’ is not a member of ‘std’

[firepol]

Hi, I'm trying to build the miner with ubuntu 17.10

First attempt: got an error

unsupported GNU version! gcc versions later than 5 are not supported

Then I installed gcc-4.8 (and later gcc-5) and retried, by configuring the gcc alternatives and got this error:

I'm stuck, what can you suggest to compile this with ubuntu 17.10? Thanks for your advise

[Amonomen]

Are you certain cmake is using g++-4.8? Try g++ --version

[firepol]

I did, it's really 4.8, or 5.5 it I switch the alternative to gcc-5... same error.

I also tried alias g++="g++ --std=c++0x" before running make, or std=c++11 (I tried all variants, all same error) etc. as suggested here: https://stackoverflow.com/questions/17378969/how-to-change-gcc-compiler-to-c11-on-ubuntu or here: https://stackoverflow.com/questions/19122574/to-string-isnt-a-member-of-std

Same error. Somewhere I think I read I have to add "CFLAGS" in the Makefile, but I'm nor familiar with make, nor gcc, nor c++ so in the end I could not make it work.

If not asking too much, it would be really nice to have a .deb file for this, I mean there are so many ubuntu users out there, why not making life easier for them?

In the end I gave up and found a docker image: https://hub.docker.com/r/unsalted/nheqminer/

Still, if some idea comes up I'll be happy to try it and compile it myself on my machine and give you feedback... thank you.

[Amonomen]

I'll attempt to reproduce your issue to get a better understanding of the issue. In the mean time, can you list your steps to reproduce? Assume it's a fresh install. List what packages you installed prior to building.

same problem, used symlinks to chose gcc and g++ versions to 5.5, no luck

I'm having the same problem on 17.10, trying to build Caffe2.
