Target Builds
----------------------------------------------------------------------------
<none> Same as 'install'
install Default target and copies it to build/rippled (default)
all All available variants
debug All available debug variants
release All available release variants
profile All available profile variants
clang All clang variants
clang.debug clang debug variant
clang.coverage clang coverage variant
clang.release clang release variant
clang.profile clang profile variant
gcc All gcc variants
gcc.debug gcc debug variant
gcc.coverage gcc coverage variant
gcc.release gcc release variant
gcc.profile gcc profile variant
msvc All msvc variants
msvc.debug MSVC debug variant
msvc.release MSVC release variant
vcxproj Generate Visual Studio 2013 project file
count Show line count metrics
Any individual target can also have ".nounity" appended for a classic,
non unity build. Example:
scons gcc.debug.nounity
If the clang toolchain is detected, then the default target will use it, else
the gcc toolchain will be used. On Windows environments, the MSVC toolchain is
also detected.
The following environment variables modify the build environment:
CLANG_CC
CLANG_CXX
CLANG_LINK
If set, a clang toolchain will be used. These must all be set together.
GNU_CC
GNU_CXX
GNU_LINK
If set, a gcc toolchain will be used (unless a clang toolchain is
detected first). These must all be set together.
CXX
If set, used to detect a toolchain.
BOOST_ROOT
Path to the boost directory.
OPENSSL_ROOT
Path to the openssl directory.
PROTOBUF_DIR
Path to the protobuf directory. This is usually only needed when
the installed protobuf library uses a different ABI than clang
(as with ubuntu 15.10).
The following extra options may be used:
--ninja Generate a `build.ninja` build file for the specified target
(see: https://martine.github.io/ninja/). Only gcc and clang targets
are supported.
--static On linux, link protobuf, openssl, libc++, and boost statically
GCC 5: If the gcc toolchain is used, gcc version 5 or better is required. On
linux distros that ship with gcc 4 (ubuntu < 15.10), rippled will force gcc
to use gcc4's ABI (there was an ABI change between versions). This allows us
to use the package manager to install rippled dependencies. It also means if
the user builds C++ dependencies themselves - such as boost - they must
either be built with gcc 4 or with the preprocessor flag
`_GLIBCXX_USE_CXX11_ABI` set to zero.
Clang on linux: Clang cannot use the new gcc 5 ABI (clang does not know about
the `abi_tag` attribute). On linux distros that ship with the gcc 5 ABI
(ubuntu >= 15.10), building with clang requires building boost and protobuf
with the old ABI (best to build them with clang). It is best to statically
link rippled in this scenario (use the `--static` with scons), as dynamic
linking may use a library with the incorrect ABI.

By default, scons scans each file for include dependecies. The implicit
cache flag lets you cache these dependencies for later builds, and will
only rescan files that change.
Failure cases are:
1) If the include search paths are changed (i.e. CPPPATH), then a file
may not be rebuilt.
2) If a same-named file has been added to a directory that is earlier in
the search path than the directory in which the file was found.
Turn on if this build is for a specific debug target (i.e. clang.debug)
If one of the failure cases applies, you can force a rescan of dependencies
using the command line option `--implicit-deps-changed`
