Main should hopefully *also* warn about this, but unless you really really want -std=c++11 or -std=c++14, it is better to leave out this configure flag (--with-cxx-dialect). <br class="">

If --with-cxx-dialect is unspecified (or set to “auto”) configure will pick the most appropriate flag for you, taking your package environment into account when choosing.

Unfortunately the nvcc compiler isn't kind enough to print the line number of the redefinition or that information is lost somehow in the build process.<br class="">

The most promising was I tried to build superlu_dist separately with the configure options that petsc passes it and then kept trying the build over and over droping out different configure options until I got it to work. In that case removing a "-std=c++14" entry appeared to fix the problem but then when I made the same change in how petsc builds superlu-dist the make failed on superlu-dist with a different error.
