These are MSVC (Visual Studio 2017) project files for the host-side tools,
|
|
namely 'luac.cross' and 'spiffsimg'. Some may find these convenient if they
|
|
already have MSVC instead of, say, setting up a Cygwin or MingW build
|
|
system.
|
|
|
|
To build 'luac.cross', you must first edit app/include/user_config.h to make
|
|
some choices about the kind of cross-compiler you are generating.
|
|
|
|
In particular, the definition of
|
|
LUA_FLASH_STORE
|
|
should be enabled if you are creating a cross-compiler for generating images
|
|
for the Lua File Storage (LFS). The specific value of this define is not
|
|
critical for luac.cross, but it's existence is if you want to be able to
|
|
generate appropriate code for LFS.
|
|
|
|
Be aware that the codebase, as checked in, has LUA_FLASH_STORE undefined.
|
|
Since it is expected that most folks wanting a host-side luac.cross is
|
|
for LFS use, you will want to first make sure that is changed to be
|
|
defined.
|
|
|
|
Secondly, if you are wanting to generate code that is appropriate for an
|
|
integer-only build, you should ensure that
|
|
LUA_NUMBER_INTEGRAL
|
|
is defined.
|
|
|
|
After altering those settings, you can build using the hosttools.sln file in
|
|
the Visual Studio UI, or directly on the command line. x86 and x64 targets
|
|
are provisioned, though there isn't anything to be gained with the 64-bit
|
|
build.
