The embedded 40250 script layer needs its own interpreter on five platforms. 2.7 is end-of-life, so nothing can be fetched from the target SDKs and the source is vendored (official 2.7.18 tarball, trimmed to 25MB; Lib/ stays for step 3's python27.zip). cpython-2.7.18/CMakeLists.txt builds one `mtpython` static library from exactly the 133 objects the reference libpython2.7.a contains, off by default behind -DMTGODOT_EMBED_PYTHON=ON. The source list and the built-in module table (config/config.c, 39 entries) are shared; pyconfig.h is a probe result and is not, so each platform keeps its own under config/<platform>/, regenerated by tools/py_embed/gen_pyconfig.sh and checked against the shared table. Three vendor patches, documented in docs/THIRD-PARTY.md: configure/configure.ac learn arm64 on macOS, and posixmodule.c undefines the process-control calls it hard-defines past pyconfig.h when building for iOS. macOS (ctest python.embed: every builtin imports, codecs and pickle work off the vendored Lib/), Android arm64 and iOS arm64 build. Linux needs a Linux host and Windows needs a MinGW-vs-MSVC decision; both are noted for step 4. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

In Win32, DLL's are "pre-linked" using a specified base address.
|
|
When the DLL is loaded, an attempt is made to place it at
|
|
that address. If that address is already in use, a new base address
|
|
is selected, and the DLL subject to fixups. Apparently, these
|
|
fixups are very slow, and significant performance gains can be
|
|
made by selecting a good base address.
|
|
|
|
This document is to allocate base addresses to core Python
|
|
and Python .PYD files, to give a better change of optimal performance.
|
|
This base address is passed to the linker using the /BASE
|
|
command line switch.
