Compiler ids

These are return values of the get_id method in a compiler object.

Value	Compiler family
gcc	The GNU Compiler Collection
clang	The Clang compiler
msvc	Microsoft Visual Studio
intel	Intel compiler
llvm	LLVM-based compiler (Swift, D)
mono	Xamarin C# compiler
dmd	D lang reference compiler
rustc	Rust compiler
valac	Vala compiler
pathscale	The Pathscale Fortran compiler
pgi	The Portland Fortran compiler
sun	Sun Fortran compiler
g95	The G95 Fortran compiler
open64	The Open64 Fortran Compiler
nagfor	The NAG Fortran compiler
lcc	Elbrus C/C++/Fortran Compiler
arm	ARM compiler
armclang	ARMCLANG compiler

Script environment variables

Value	Comment
MESON_SOURCE_ROOT	Absolute path to the source dir
MESON_BUILD_ROOT	Absolute path to the build dir
MESONINTROSPECT	Command to run to run the introspection command, may be of the form python /path/to/meson introspect, user is responsible for splitting the path if necessary.
MESON_SUBDIR	Current subdirectory, only set for run_command

CPU families

These are returned by the cpu_family method of build_machine, host_machine and target_machine. For cross compilation they are set in the cross file.

Value	Comment
x86	32 bit x86 processor
x86_64	64 bit x86 processor
ia64	Itanium processor
arm	32 bit ARM processor
aarch64	64 bit ARM processor
mips	32 bit MIPS processor
mips64	64 bit MIPS processor
ppc	32 bit PPC processors (Big Endian)
ppc64	64 bit PPC processors (Big Endian)
ppc64le	64 bit PPC processors (Little Endian)
e2k	MCST Elbrus processor
parisc	HP PA-RISC processor
sparc64	SPARC v9 processor

Any cpu family not listed in the above list is not guaranteed to remain stable in future releases.

Operating system names

These are provided by the .system() method call.

Value	Comment
linux
darwin	Either OSX or iOS
windows	Any version of Windows
cygwin	The Cygwin environment for Windows
haiku
freebsd	FreeBSD and its derivatives
dragonfly	DragonFly BSD
netbsd

Any string not listed above is not guaranteed to remain stable in future releases.
