document recommended compiler #106

Closed caseyjlaw closed 6 years ago

caseyjlaw commented 6 years ago

I'm trying to build at the NRAO, but they have a relatively old g++. It fails when trying with the flag -std=c++11. Seems that is only supported for g++ after 4.6 (https://stackoverflow.com/questions/10363646/compiling-c11-with-g). Can you document some recommendations on compilers that have been tested?

We may have only tested with Ubuntu 14.04 (gcc 4.8) and later. I can try building against older versions when I have a chance and will document what I find.

What version of g++ is actually available at NRAO? (Also, what CUDA version?). Supporting C++98 in Bifrost will probably not be possible at this stage, but there may be some ways to work around it.

They seem to use 4.4.7 as default on RHEL6.8. I have installed 4.8.5 via anaconda. I'll see what I can do. Some coverage would help, but a quick note in the docs was all I hoped for.

Hi @caseyjlaw, thanks for pointing this out! I have added a note to the docs.

Cheers, Miles
