- migrate to c++14 for most compilers *except* gcc.
There are still many systems in use with gcc-4.8.5, which does not
support c++14.
- initial rules for nvidia compilers (pgi is will soon be defunct).
Not fully tested...
CONFIG: provide fallback value for the user directory name
- in containers may have an unset USER env variable.
Default to 'user' to prevent ugly looking directory names.
- largely as per patch from Jong-Gwan (Jason) Do
NB: the intel-one setup adds in paths for intelmpi.
Its mpicc version does not harmonize with the OpenFOAM
system openmpi setup (using mpicc --showme:link).
Needs adjustment, or use intelmpi instead.
- update name mappings for newer gcc, clang versions
- prefix FOAM_MPI and library directories with 'sys-' for system
versions for uniform identication.
WM_MPLIB | libdir (FOAM_MPI) | old naming |
SYSTEMMPI | sys-mpi | mpi |
SYSTEMOPENMPI | sys-openmpi | openmpi-system |
- prefix preferences with 'prefs.' to make them more easily
identifiable, and update bin/tools/create-mpi-config accordingly
Old name: config.{csh,sh}/openmpi
New name: config.{csh,sh}/prefs.openmpi
- additional mpi preferences now available:
* prefs.intelmpi
* prefs.mpich
...
CONFIG: added hook for EASYBUILDMPI (eb-mpi), somewhat like USERMPI
- EasyBuild uses mpicc when compiling, so no explicit wmake rules are
used
ENH: support different major versions for system openmpi
- for example, with
WM_MPLIB=SYSTEMOPENMPI2
defines FOAM_MPI=sys-openmpi2 and thus creates lib/sys-openmpi2
ENH: centralize handling of mpi as 'mpi-rules'
Before:
sinclude $(GENERAL_RULES)/mplib$(WM_MPLIB)
sinclude $(DEFAULT_RULES)/mplib$(WM_MPLIB)
ifeq (,$(FOAM_MPI_LIBBIN))
FOAM_MPI_LIBBIN := $(FOAM_LIBBIN)/$(FOAM_MPI)
endif
After:
include $(GENERAL_RULES)/mpi-rules
- also allows variants such as SYSTEMOPENMPI2 to be handled separately
- consistent with FOAM_SIGFPE etc.
- centralize code as error::useAbort() static function to avoid
scattering the logic throughout the code.
ENH: also accept "0" and "1" string values for Switch
- not the normal path for Switch input (eg, from a dictionary), but
consistent with bool definitions and simplifies string parsing.
This means that `FOAM_SIGFPE=1 application` will now also work.
- introduce WM_COMPILE_CONTROL variable to convey control information
into the build rules.
The convention (as per spack):
- '+' to select a feature
- '~' to deselect a feature
Eg, to select the gold linker, and disable openmp
(spaces are not required):
WM_COMPILE_CONTROL="+gold ~openmp"
CONFIG: accept FOAM_EXTRA_LDFLAGS for AMD, gold, Mingw linkers
CONFIG: generalize PROJECT_LIBS (-ldl used almost universally)
- When compiling additional modules or user code, we need more control
for the installation locations beyond the usual FOAM_USER_LIBBIN,
FOAM_SITE_LIBBIN, FOAM_LIBBIN, and wish to have these values be
modifiable without editing files.
- provide wmake rules for handling standard defaults:
* GENERAL_RULES/module-path-user
* GENERAL_RULES/module-path-group
* GENERAL_RULES/module-path-project
which are incorporated as follows:
Make/options:
include $(GENERAL_RULES)/module-path-user
Make/files:
LIB = $(FOAM_MODULE_LIBBIN)/libMyLibrary
By default these would compile into FOAM_USER_{APPBIN,LIBBIN} but
could be adjusted at compilation time. For example,
```
wmake -module-prefix=/path/my-install-location
```
Or
```
./Allwmake -module-prefix=/path/my-install-location
./Allwmake -prefix=/path/my-install-location
```
Or
```
FOAM_MODULE_PREFIX=/path/my-install-location ./Allwmake
```
ENH: add -no-recursion option for AllwmakeParseArguments
- more descriptive naming than the -fromWmake option (still supported)
- remove wmake/scripts/wmake.{cmake,wmake}-args since the -prefix
handling and -no-recursion is now directly handled by AllwmakeParseArguments
- missed detection of system libraries when installed with multiarch
paths like /usr/lib/x86_64-linux-gnu
CONFIG: improve handling of group/user config files (#928)
- changed bashrc handling of FOAM_CONFIG_NOUSER to use
FOAM_CONFIG_MODE instead. Propagate into foamEtcFile to make this
a stickier control.
This change allows better control, but also enables cluster
installations to define their own value within the OpenFOAM prefs.sh
file to prevent users accidentally mis-configuring things if
necessary.
- remove undocumented handling of an (a)ll mode in foamEtcFile to
avoid potential pitfalls.
- add support for FOAM_CONFIG_ETC handling.
This allows injection of an extra search layer when finding
project etc files
ENH: improvements to foamConfigurePaths (#928)
- handle FOAM_CONFIG_ETC implicitly, or explicitly with the new
-etc option.
STYLE: more explicit wording in foamConfigurePaths usage (#1602)
- document that an absolute path (eg, -scotch-path) overrides/ignores
the equivalent ThirdParty setting (eg, -scotch)
- longer options -system-compiler and -third-compiler for -system
and -third, respectively. Clearer as to their purpose.
- adjust the location sanity check to look for META-INFO directory.
- '-c' option (as per shell), '-Dkey[=value]' option to provide
preferences via the command-line. For example,
etc/openfoam -DWM_COMPILER=Clang -int64 ./Allwmake -j -s -l
These can also be combined with other options. Eg,
etc/openfoam -DWM_COMPILER=Clang \
-c 'wmake -show-path-cxx -show-cxxflags'
- relocated from bin/tools/ => etc/ for easier access
- bin/tools/openfoam.in : for autoconfig-style installation
- Auto-detect if the shell script was executed with openfoam and
interpret accordingly.
Simple example,
--------------
#!/usr/bin/openfoam
cd "${0%/*}" || exit # Run -*-sh-*- from this dir
blockMesh
simpleFoam
--------------
Note it is NOT currently possible to provide any other parameters
this way. Eg,
`#!/usr/bin/openfoam -sp` (NOT)
This will either fail to run, or result in infinite recursion.
- locate where the user is less tempted to change it (#1515).
It really should be considered an invariant environment variable.
STYLE: wmake -help information to stdout, die errors to stderr
- call also be used non-interactively for simple 'one-shot' use of
OpenFOAM utilities or solvers
STYLE: use dash instead of brackets for '- see www.OpenFOAM.com'
- less cluttered in combination with API information
- add a '-SPDP' option
- remove the '-archOption' for forcing a '-m32' build on 64-bit
architecture, which is now considered too obscure.
Must edit files manually if this option is really required.
- now only needed when specify compiling -m32 on a 64-bit system.
Internally use the __SIZEOF_LONG__ compiler macro (gcc, icc, llvm)
to define when long is actually an int32_t.
- in addition to managing different vendors and versions, it may also
be necessary or desirable to have a particular variant
(eg, profiling, release, etc).
Devise a new meaningful name for the variant and create a
corresponding wmake rule.
Eg, SYSTEMOPENMPI-profiling with a corresponding
"wmake/rules/linux64Gcc/mplibSYSTEMOPENMPI-profiling" file
that has suitable content for your system.
CONFIG: intel-mpi use intel64/ paths only for config and wmake rules (#1153)
- previously adjusted the config files, but missed the changes
required for the wmake rules too.
Now simply migrate to using "intel64/{include,bin,lib}"
instead of the older naming "{include,bin,lib}64"
These changes work since at least intel-mpi 2015 (5.x), but possibly
earlier as well
- instead of
WM_COMPILER=GccKNL WM_COMPILE_OPTION=Opt
-> linux64GccKNLDPInt32Opt
now specify
WM_COMPILER=Gcc WM_COMPILE_OPTION=OptKNL
-> linux64GccDPInt32OptKNL
This makes it easier (and more obvious) for adding different tweaks
without needing to generate too many files.
Eg,
cd wmake/rules/linux64Gcc
cp cOpt cOptBdw
cp c++Opt c++OptBdw
edit these two files and then use WM_COMPILE_OPTION=OptBdw
CONFIG: provide some default c/c++ flags in General compiler rules
- can make is easier when deriving new compile options, and ensures
that '-02' is enabled as an initial default.
- was WM_PROJECT_API in the environment and FOAM_API in dictionaries.
Make these both consistently FOAM_API.
This is a non-breaking change, since the value of WM_PROJECT_API
(added in 1812) and/or FOAM_API is purely informative.
For the current correct values, always use
* foamEtcFile -show-api
* wmakeBuildInfo -show-api
- was WM_PROJECT_API in the environment and FOAM_API in dictionaries.
Make these both consistently FOAM_API.
This is a non-breaking change, since the value of WM_PROJECT_API
(added in 1812) and/or FOAM_API is purely informative.
For the current correct values, always use
* foamEtcFile -show-api
* wmakeBuildInfo -show-api
- Use the OPENFOAM define (eg, 1806, 1812), which normally corresponds
to a major release, to define an API level. This remains consistent
within a release cycle and means that it is possible to manage
several sub-versions and continue to have a consistent lookup.
The current API value is updated automatically during the build
and cached as meta data for later use, even when the wmake/ directory
is missing or OpenFOAM has not yet be initialized.
The version information reported on program start or with -help
usage adjusted to reflect this. The build tag from git now also
carries the date as being more meaningful to trace than a hash
value.
- Update etc/bashrc and etc/cshrc to obtain the project directory
directly instead of via its prefix directory. The value obtained
corresponds to an absolute path, from which the prefix directory
can be obtained.
The combination of these changes removes the reliance on any
particular directory naming convention.
For example,
With an 1812 version (API level):
WM_PROJECT_VERSION=myVersion
installed as /some/path/somewhere/openfoam-mySandbox
This makes the -prefix, -foamInstall, -projectVersion, -version
values of foamEtcFiles, and similar entries for foamConfigurePaths
superfluous.
WM_PROJECT_INST_DIR is no longer required or used
ENH: improve handling and discovery of ThirdParty
- improve the flexibility and reusability of ThirdParty packs to cover
various standard use cases:
1. Unpacking initial release tar files with two parallel directories
- OpenFOAM-v1812/
- ThirdParty-v1812/
2. With an adjusted OpenFOAM directory name, for whatever reason
- OpenFOAM-v1812-myCustom/
- openfoam-1812-other-info/
3. Operating with/without ThirdParty directory
To handle these use cases, the following discovery is used.
Note PROJECT = the OpenFOAM directory `$WM_PROJECT_DIR`
PREFIX = the parent directory
VERSION = `$WM_PROJECT_VERSION`
API = `$WM_PROJECT_API`, as per `foamEtcFiles -show-api`
0. PROJECT/ThirdParty
- for single-directory installations
1. PREFIX/ThirdParty-VERSION
- this corresponds to the traditional approach
2. PREFIX/ThirdParty-vAPI
- allows for an updated value of VERSION (eg, v1812-myCustom)
without requiring a renamed ThirdParty. The API value
would still be '1812' and the original ThirdParty-v1812/
would be found.
3. PREFIX/ThirdParty-API
- this is the same as the previous example, but using an unadorned
API value. This also makes sense if the chosen version name also
uses the unadorned API value in its naming
(eg, 1812-patch190131, 1812.19W03)
4. PREFIX/ThirdParty-common
- permits maximum reuse for various versions, but only for
experienced user who are aware of potential version
incompatibilities
Directory existence is checked as is the presence of an Allwmake file
or a platforms/ directory. This reduces the potential of false positive
matches and limits the selection to directories that are either
with sources (has the Allwmake file), or pre-compiled binaries (has
the platforms/ directory).
If none of the explored directories are found to be suitable,
it reverts to using a PROJECT/ThirdParty dummy location since
this is within the project source tree and can be trusted to
have no negative side-effects.
ENH: add csh support to foamConfigurePaths
- this removes the previously experienced inconsistence in config file
contents.
REMOVED: foamExec
- was previously used when switching versions and before the
bashrc/cshrc discovery logic was added. It is now obsolete.
- provide default WM_DIR if not already set, to improve robustness if a
reduced environment is used
- add etc/ to WM_PROJECT_SITE search. This makes the site directory
structure consistent with the OpenFOAM structure.
Eg,
WM_PROJECT_SITE/etc/..
WM_PROJECT_SITE/bin/..
WM_PROJECT_SITE/platforms/..
- Don't set/export WM_OSTYPE. The default is POSIX and is properly
defaulted throughout, including in CMakeLists-OpenFOAM.txt (also for
Catalyst)
- was PREFIX/site, now PROJECT/site
This avoids several issues when installing OpenFOAM in clusters
without an intermediate OpenFOAM-specific installation prefix.
The 'site' directory may have a reserved meaning in these situations
and it is undesirable to 'leak' upwards into the parent directory to
look for configuration files.
Placing the default within the project directory avoids this.
Alternative locations can be given via the WM_PROJECT_SITE variable.
- foamCleanPath now only splits the environment variable on ':', which
allows other directories with spaces or '(..)' etc to pass through
without major issue.
- The filter arguments are split on whitespace, colons or semi-colons.
- this avoids a situation when an aborted sourcing of the etc/bashrc
file can leave WM_SHELL_FUNCTIONS defined, which causes all
subsequent sourcing to fail.
- FOAM_CONFIG_NOUSER
Suppress use of user/group configuration files.
This is useful when packaging for a central installation.
- allow additional user tuning of compiler settings.
Per-compiler overrides in "compiler-$WM_COMPILER" files
