- 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
- only wrap compiler calls (not things like flex/bison)
- avoid single quoted '&&' (causes syntax errors)
STYLE: report WM_COMPILE_CONTROL value in top-level Allwmake
Eg,
export WM_COMPILER=Clang130
export WM_COMPILE_CONTROL="version=13.0 +lld"
- also support the mold linker (+mold) for clang
STYLE: report as 'link' stage instead of 'ld' in short messages
- was taking from the current head instead from specified commit-ish
ENH: add -debian=NUM convenience option to foamPackRelease
STYLE: relocate compile begin/end messages
COMP: suppress more clang warnings (needed for boost)
- for compilers such as gcc and clang, may have several different
variants installed on the computer. Use WM_COMPILER_CONTROL to
specify the preferred variant.
Eg,
WM_COMPILER=Gcc
WM_COMPILER_CONTROL="version=8"
will compile with "gcc-8" and "g++-8"
Good practice would be to tag output directory names with the
version too. Eg
WM_COMPILER=Clang110
WM_COMPILER_CONTROL="version=11.0"
STYLE: modify message for change of gcc -> clang (darwin)
- it is now possible to include the selected mpi version in the
top-level bashrc or prefs.sh file. For example,
WM_MPLIB=OPENMPI-4.1.1 or WM_MPLIB=openmpi-4.1.1
after evaluation of the config.sh/mpi, this will define
WM_MPLIB=OPENMPI-4.1.1 and FOAM_MPI=openmpi-4.1.1
During the wmake, the mpi-rules will first load the MPI 'family'
rules (OPENMPI in this example) before trying to load
version-specific rules if they exist.
NOTE: the regular user-defined prefs system is unaffected by this
change. This means it is still possible to use a file such as
'prefs.openmpi' to define the preferred version instead or as well.
However, it does mean inconsistent naming can be specified.
For example, specify WM_MPLIB=OPENMPI-4.1.1 at the top-level but
actually have FOAM_MPI=openmpi-4.0.6 in the prefs.openmpi file.
This will make the value of WM_MPLIB misleading.
CONFIG: foamConfigurePaths support for sys-openmpi major version
CONFIG: cleanup any shadow env variables
- 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
- previously had a very old (likely irrelevant) setting for solaris
systems only.
- support site-specific customization.
Eg, using etc/config.{csh,sh}/prefs.fjmpi
- remove erroneous shell redirects present in cshell files
- 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
- 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
- dependency handling relocated from cmakeFunctions to wmakeFunctions
and reused for mpi-versioned builds. This allows more checks for
configuration parameters and removes hard-code build path
information.
CONFIG: remove spurious mplibHPMPI entries
CONFIG: remove ADIOS1 rules (antiquated)
- initial split of wmake-related commands into "plumbing" and
"porcelain" akin to how git handles things.
- wmakeBuildInfo (very low-level), now relocated to the wmake/scripts
and accessible for the user as "wmake -build-info".
This satisfies a long-standing desire to access build information
in a fashion similar to the api/patch information.
CONFIG: avoid git information when building with a debian/ directory
- when a 'debian/' directory exists, there is a high probability that
the '.git/' directory is from debian and not from OpenFOAM (ie,
useless here). This corresponds to an implicit '-no-git', which has
no effect when building from pristine sources.
ENH: wmakeCheckPwd becomes scripts/wmake-check-dir
- accessible for the user as "wmake -check-dir" and with 1 or 2
directory names. A wmakeCheckPwd symlink left for compatibility.
- add '[-+.~]' to the recognized qualifiers.
This allows simple readable names such as
WM_COMPILER=Clang-vendor
but also opens the FUTURE (not yet supported) possibility of
combining in additional information. For example,
WM_COMPILER=Clang~openmp
WM_COMPILER=Clang+cuda~openmp
by using '+' (add) and '~' (subtract) notation similar to what
spack uses.
CONFIG: support 'override' rules
- if present, compiler-family 'override' rules are included after
compiler-family 'general' rules have been included. This allows a
central means for including dynamically generated content to
override some values.
Some examples:
To handle different gcc versions (system compiler):
wmake/rules/...Gcc/override
```
ifneq (,$(findstring 9, $(WM_COMPILER)))
cc := gcc-9
CC := g++-9 -std=c++11
endif
```
To handle different openmp on Darwin (#1656):
wmake/rules/darwin64Clang/override
```
# Use libomp (not libgomp) unless openmp is disabled
ifeq (,$(findstring "~openmp", "$(WM_COMPILER)"))
COMP_OPENMP = -DUSE_OMP -Xpreprocessor -fopenmp
LINK_OPENMP = -lomp
else
include $(GENERAL_RULES)/no-openmp
endif
```
This treatment arguably fits into wmake/rules/darwin64Clang/general,
but it serves to illustrate a possible use case.
