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>

If you are have a problem building on OpenBSD and see output like this
|
|
while running configure:
|
|
|
|
checking curses.h presence... yes
|
|
configure: WARNING: curses.h: present but cannot be compiled
|
|
configure: WARNING: curses.h: check for missing prerequisite headers?
|
|
configure: WARNING: curses.h: see the Autoconf documentation
|
|
configure: WARNING: curses.h: section "Present But Cannot Be Compiled"
|
|
configure: WARNING: curses.h: proceeding with the preprocessor's result
|
|
configure: WARNING: curses.h: in the future, the compiler will take precedence
|
|
|
|
there is likely a problem that will prevent building python.
|
|
If you see the messages above and are able to completely build python,
|
|
please tell python-dev@python.org indicating your version of OpenBSD
|
|
and any other relevant system configuration.
|
|
|
|
The build error that occurs while making may look something like this:
|
|
|
|
/usr/include/sys/event.h:53: error: syntax error before "u_int"
|
|
/usr/include/sys/event.h:55: error: syntax error before "u_short"
|
|
|
|
To fix this problem, you will probably need update Python's configure
|
|
script to disable certain options. Search for a line that looks like:
|
|
|
|
OpenBSD/2.* | OpenBSD/3.@<:@012345678@:>@)
|
|
|
|
If your version is not in that list, e.g., 3.9, add the version
|
|
number. In this case, you would just need to add a 9 after the 8.
|
|
If you modify configure.ac, you will need to regenerate configure
|
|
with autoconf.
|
|
|
|
If your version is already in the list, this is not a known problem.
