Is there a header missing? Or a C++ standard flag?

I understand from cppreference that this type is optionally defined, so maybe you shouldn't rely on it?

PS this appears in testing code. Is there a flag to disable generating gtest code?

@VictorEijkhout From what I can tell, this version of gtest we bundled with Trilinos was very old (1.10 from 2019) which is probably the cause. New versions of gtest.h have #include <cstdint>. The 16.2.0 release you're using still has the bundled gtest, but we got rid of it in develop last month in #14719.

You might have found this already but configuring with -DTrilinos_ENABLE_Gtest=OFF will avoid building it.

Trying to find the gtest option is probably what caused my ticket about the cmake rference being missing :-)

cstdint would indeed solve it.
