Some very simple documentation requests

[markyoder]

Hi - Can I request/recommend some very simple modifications to the installation documentation?

Namely, what compilers should be what? For example, I understand that the environment variable CC is interpreted by cmake as the c-compiler, but it is not clear to me whether that should be set to the gnu compiler, or the nvhpc compiler. Should this look something like,
CC=gcc or CC=nvc

Also, I understand that there are many c++ standards, but how specifically should -DSTD= be defined? -DSTD=11, -DSTD=c++11, ???

Turns out I can find this by sifting through the "successful builds," but a short, basic explanation in the "install" section of how to make certain specifications would be extremely helpful.

Thanks in advance for any clarity you can provide!

No problem. I'll further clarify the documentation later.

Very much appreciate it! And when I get it working, I'll share my Spack environment. Thanks! mark Mark Yoder, PhD 805 451 8750 *www.linkedin.com/in/Mark-R-Yoder-PhD <http://www.linkedin.com/in/Mark-R-Yoder-PhD>* "If you bore me, you lose your soul (to me)..." ~belly

Your questions are answered in the relevant paragraphs in the updated documentation. https://github.com/TinkerTools/tinker9/blob/master/doc/manual/m/install/buildwithcmake.rst

And if you really want to use c++14, you can try cmake ... -DSTD=14 or std=14 cmake ... as documented in the "Configure Tinker9" section. I agree they look like commands such as clang++ -c -std=c++14 ..., but please note that -DSTD=/std= is the hook I added in the CMake scripts for Tinker9, and is passed to CMake. We do not directly handle Makefile. Setting syntax standards for CUDA and OpenACC compilers may be different for different compilers.
