- remove unneeded -Wno-old-style flags with boost/cgal elements
- add nvc equivalent to gcc/clang -Wno-invalid-offsetof
- avoid warnings about set-but-unused variable and change of scoping
STYLE: remove wmake 'CGAL' rule
- was a transitional forward to 'cgal' rule since DEC-2020
- renumberMesh now has -dry-run, -write-maps, -no-fields,
-renumber-method, -renumber-coeffs options.
* Use -dry-run with -write-maps to visualize the before/after
effects of renumbering (creates a VTK file).
* -no-fields to renumber the mesh only.
This is useful and faster when the input fields are uniform
and the -overwrite option is specified.
* -renumber-method allows a quick means of specifying a different
default renumber method (instead of Cuthill-McKee).
The -renumber-coeffs option allows passing of dictionary content
for the method.
Examples,
// Different ways to specify reverse Cuthill-McKee
* -renumber-method RCM
* -renumber-coeffs 'reverse true;'
* -renumber-method CuthillMcKee
* -renumber-coeffs 'reverse true;'
* -renumber-coeffs 'method CuthillMcKee; reverse true;'
// Other (without dictionary coefficients)
* renumberMesh -renumber-method random
// Other (with dictionary coefficients)
renumberMesh \
-renumber-method spring \
-renumber-coeffs 'maxCo 0.1; maxIter 1000; freezeFraction 0.99;'
// Other (with additional libraries)
renumberMesh -renumber-method zoltan -lib zoltanRenumber
COMP: build zoltan renumbering to MPI-specific location
- zoltan and Sloan renumbering are now longer automatically linked to
the renumberMesh utility but must be separately loaded by a
command-line option or through a dictionary "libs" entry.
ENH: add output cellID for decomposePar -dry-run -cellDist
- for clang-based compilers the default linker may be lld or simply ld.
Support '+link-ld' to explicitly select use of the ld linker.
- consolidate linker rules into single files
STYLE: adjust SPDX Identifier
- give precedence to ~openmp (-no-openmp) over +openmp (-openmp)
in the general rules and in the Makefile. This makes it robuster
when specifying +openmp in general, but ~openmp for specific build
components.
- disable openmp for OSspecific and Pstream components.
Neither should contain any openmp code anyhow.
Additionally, since OSspecific is generally built as a static
object, it can become problematic (eg, with AMD ROCm) if the
compiler generates information that openmp is required but then uses
static linkage.
- selected with '+strict' in WM_COMPILE_CONTROL or 'wmake -strict', it
enables the FOAM_DEPRECATED_STRICT() macro, which can be used to
mark methods that are implicitly deprecated, but are not yet marked
as full deprecated (eg, API modification is too recent, generates
too many warnings). Can be considered a developer option.
- since the Apple SIP (System Integrity Protection) clears environment
variables such as DYLD_LIBRARY_PATH, a number of workarounds have
been used to provide shadow values. However, for a more robust
installation using -rpath at compilation time appears to be the
better solution.
In addition to the usual -rpath specification with absolute file
paths, MacOS supports (@loader_path, @executable_path) as well.
Now default to link with rpath information for MacOS, which can be
disabled by adding `~rpath` in WM_COMPILE_CONTROL
Explicit library paths handled:
- FOAM_FOAM_EXT_LIBBIN, FOAM_EXT_LIBBIN/FOAM_MPI
The executable rpaths are handled assuming a structure of
install-path/bin
install-path/lib/$(FOAM_MPI)
install-path/lib
Absolute compile-time paths for FOAM_USER_LIBBIN, FOAM_SITE_LIBBIN
and FOAM_LIBBIN are not handled since these are either too fragile
(FOAM_USER_LIBBIN and FOAM_SITE_LIBBIN values) or covered via
@loader_path anyhow (FOAM_LIBBIN).
Since the value of FOAM_MPI is a compile-time value, this rpath
treatment makes the installation less suitable for runtime changes
to the MPI vendor/version.
Note: no rpath added for c-only compilations since there are
currently no c-only libraries or executables with dynamic loading
- other systems (eg, ARM64 linux with clang) do not have a separate
mpfr library configured so also check for mpfr (gmp is assumed to be
the same) and return corresponding cgal flavour (eg, header-no-mpfr)
COMP: update include for CGAL-5.5 (#2665)
old: Robust_circumcenter_filtered_traits_3
new: Robust_weighted_circumcenter_filtered_traits_3
COMP: adjust CGAL rule for OSX (#2664)
- since CGAL is now header-only, the previous OSX-specific rules have
become redundant
- eg, for partially incomplete systems (without libz devel header)
ENH: clearer binding of dummy Pstream in OpenFOAM/Make/options
- link of dummy stub Pstream now contingent on linking libOpenFOAM as
well. This makes the purpose slightly clearer
ENH: cleaner option naming/handling in wmake script
- allow special purpose -no-openfoam option.
Eg, compiling test programs without OpenFOAM and Pstream libraries
but using the rest of the wmake system.
ENH: add +openmp support into WM_COMPILE_CONTROL (#2633)
- this adds compile/link flags for openmp.
For single-use, can also use 'wmake -openmp'.
If both +openmp and ~openmp are specified in WM_COMPILE_CONTROL
the ~openmp will have priority.
This is actually done indirectly since ~openmp will set empty
COMP_OPENMP, LINK_OPENMP internal variables, which the +openmp then
adds to the c++FLAGS and linkexe targets (ie, won't actually add
anything).
ENH: add +ccache or ccache=... support into WM_COMPILE_CONTROL (#2633)
- with the first version (+ccache), simply use ccache from the path
without any extra options.
- with the second version (ccache=...), can be more specific about
what is called.
Using "+ccache" is identical to "ccache=ccache", but the later could
be used in other ways. For example,
ccache=/strange/install/path/ccache
ccache=</path/my-tooling --option>
Have the choice of unquoted, single or double quoted or '< >' quoted
STYLE: relocate FOAM_EXTRA_LDFLAGS in general makefile
- removes clutter for different linkers (eg, gold, mold, ldd)
making it easier to extend for other linkers.
STYLE: protect makefile checks with 'strip' function
- uses '-g -DFULLDEBUG' (like Debug), but with -O3 (like Opt).
This adds in debug symbols and FULLDEBUG code segments (good for
code development) but retains -O3 optimizations and code paths and
avoids the much slower -O0 associated with 'Debug'.
- add in central wmake/General/common/{c,c++}XXX tuning,
which helps reduce the number of nearly identical files
ENH: add support for wmake -debug-Og
- the cpp command is used to process Make/{files,options}, but builtin
defines such as `linux` will cause problems (macro replacement) if
these is present in the Make/{files,options}.
Solve by undefining -Ulinux, -Uunix macros, which will leave directory
names such as "/usr/lib/x86_64-linux-gnu/..." intact.
Directories with _linux, __linux__ content (for example), could
still pose future issues.
