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)
- 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.
- 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)
- 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.
