Trilinos 12.12 -- install cygwin, windows 10

[J Jacob Wikner]

Hello,

what error do we do if we get the:

"error: ‘gethostname’ was not declared in this scope"

in the Teuchos_XMLPerfTestArchive.cpp ?

Windows 10, Xyce 7.2

You should add "-D_BSD_SOURCE -D_GNU_SOURCE" to your CMAKE_CXX_FLAGS when building Trilinos, and to CXXFLAGS when building Xyce.

We have already updated the building guide to include this requirement in the upcoming release version of the building guide, but that's not published yet.

I should also say that the "-D_BSD_SOURCE -D_GNU_SOURCE" is *only* needed for Cygwin.

Thanks!

Noticed that bootstrap does not work for the Xyce compilation and that the INSTALL file does not reflect that. Perhaps something for the building guide in next release too.

"bootstrap does not work for the Xyce compilation"

Could you explain that statement?  Since it's done for every single Xyce build during testing and development, we'll need a little more context to explain why it might not be working for you.

Also, as the INSTALL document says at the top, the definitive documentation for building Xyce is NOT in the INSTALL file, which is a generic product of the autoconf system.  The definitive documentation for building Xyce is our building guide at https://xyce.sandia.gov/documentation/BuildingGuide.html
