- export/setenv WM_COMPILER_TYPE as suggested by Mattijs.
- for overall consistency, don't carp about an unset WM_COMPILER_TYPE,
since this would only be on the first instance (prior to the
export/setenv) and would be confusing about why/when this message
may occur.
- reduce clutter: only use (system|ThirdParty) for WM_COMPILER_TYPE.
Drop the old 'OpenFOAM' setting for WM_COMPILER_TYPE, which was
transitional in early 2011.
- make the error messages more meaningful
The change from C++0x to C++11 allows all of C++11 functionality to be
used in OpenFOAM, in particular constructor delegation which avoids code
duplication or constructor helper functions. However, this also means a
change to the minimum gcc version supported which is now 4.7 rather than
4.5.
Note that gcc-4.7 does not support the entire C++11 standard but does
support all of the functionality currently needed for further OpenFOAM
development. The minimum gcc-version which supports the entire C++11
standard is 4.8 which is now the recommended minimum gcc version.
- move unset mpi buffer size from config.csh/settings -> config.csh/mpi
- wmUNSET now also unalias wmREFRESH
Note: unsetenv WM_COMPILER_TYPE in csh variant?
- drop reference to paraview-3 in config files.
Cannot say anything definite about support for versions
this old (2012)
- not previously possible to configure a third-party gcc
with system gmp/mpfr/mpc.
This makes it easier to switch between compilers for testing.
- use system libraries by default
etc/config.sh and etc/config.csh
This structure is more convenient to add support for other shells, e.g. zsh, fish etc.
Resolves feature request to simplify support for other shells in
