The changelog of Sundials 4.0.0 states:
"With the introduction of SUNNonlinSol modules, the input parameter iter
to CVodeCreate has been removed along with the function CVodeSetIterType
and the constants CV_NEWTON and CV_FUNCTIONAL.
Similarly, the ITMETH parameter has been removed from the Fortran interface
function FCVMALLOC. Instead of specifying the nonlinear iteration type
when creating the CVODE(S) memory structure, CVODE(S) uses
the SUNNONLINSOL_NEWTON module implementation of a Newton iteration by default."
so the appropreate conditional changes are added to control
the code execution via CT_SUNDIALS_VERSION preprocessor variable
to omit the parameters of Sundials solver that are no longer required.
Some distributions (e.g. Fedora/RHEL) use 'lib64' instead of 'lib'
on 64-bit systems or could use some other library directory name
instead of 'lib' depends on architecture and profile
(e.g. Gentoo 'libx32' on x32 profile).
If user didn't set 'libdirname' configuration variable then
set it to default value 'lib'
This commit is related to early closed issue:
https://github.com/Cantera/cantera/issues/318
Use the Cython module from the Python installation specified by
'python_cmd', rather than the Python installation that is running
SCons. This allows complilation of Cantera for Python versions that
aren't supported by SCons (e.g. Python 3.4).
Recent versions of clang++ warn that instantiation of a templated variable is
required at a certain point where no definition is available. Declaring such a
definition to be available is fine with older versions of clang++ as well, but
causes linker errors with g++, so this change is only applied when using
clang++.
New scons build option introduced to replace 'system_googletest'
and allow to not use 'googletest' module while running test
(all tests that require this module could be omited)
New option description:
'googletest',
"""Select whether to use gtest/gmock from system
installation ('system'), from a Git submodule ('submodule'), to decide
automatically ('default') or don't look for gtest/gmock ('none')
and don't run tests that depend on gtest/gmock.
If this option is set then it suppress the deprecated 'system_googletest' option."""
Old option is still presented and mentioned as 'deprecated'.
Option 'googletest' supresses the old 'system_googletest' one.
Adds a new internal-only option for the pythonX_package variables,
'minimal-default'. This value is set when pythonX_package has not been
configured by the user (i.e., it started as default) and checking for
Cython or NumPy fails, so we can't build the full interface.
If python_package is default and pythonX_package is present (where X is
the same version of Python as python_package), prefer the
pythonX_package options and don't warn quite so much
