[section:requirements Requirements]
|
|
|
|
If __boost_context__ uses fcontext_t (the default) as its implementation,
|
|
it must be built for the particular compiler(s) and CPU architecture(s)
|
|
being targeted.
|
|
Using [link implementation ['fcontext_t]], __boost_context__ includes assembly
|
|
code and, therefore, requires GNU as and GNU preprocessor for supported POSIX
|
|
systems, MASM for Windows/x86 systems and ARMasm for Windows/arm systems.
|
|
|
|
[note MASM64 (ml64.exe) is a part of Microsoft's Windows Driver Kit.]
|
|
|
|
[important Please note that `address-model=64` must be given to bjam command
|
|
line on 64bit Windows for 64bit build; otherwise 32bit code will be generated.]
|
|
|
|
[important For cross-compiling the lib you must specify certain additional
|
|
properties at bjam command line: `target-os`, `abi`, `binary-format`,
|
|
`architecture` and `address-model`.]
|
|
|
|
[important Windows using fcontext_t: for safe SEH the property 'asmflags=\safeseh' must be specified at
|
|
bjam command line.]
|
|
|
|
[important Windows using fcontext_t: turn off global program optimization (/GL) and change /EHsc (compiler
|
|
assumes that functions declared as extern "C" never throw a C++ exception) to /EHs (tells
|
|
compiler assumes that functions declared as extern "C" may throw an exception).]
|
|
|
|
Because this library uses C++11 extensively, it requires a compatible compiler.
|
|
Known minimum working versions are as follows: Microsoft Visual Studio 2015
|
|
(msvc-14.0), GCC 4.8 (with -std=c++11), Clang 3.4 (with -std=c++11). Other
|
|
compilers may work, if they support the following language features: auto
|
|
declarations, constexpr, defaulted functions, final, hdr thread, hdr tuple,
|
|
lambdas, noexcept, nullptr, rvalue references, template aliases. thread local,
|
|
variadic templates.
