By breaking independent parts of the build into stages breaks implied
dependencies between those parts. A tool built later will not require
rebuilding when earlier unrelated tools are changed. That includes
upgrades to require new downloads. Most tools can be upgraded without
requiring unnecessary rebuilds.
When a build command is sufficiently simple, GNU Make simulates a shell
("fast") instead of starting a real shell ("slow"). This simulation is
defective, such as incorrectly resolving executables, ignoring $PATHEXT,
and so on. The "fast" path does not appear to be faster, so rather than
fix it just disable it with a small patch.
The convention is ALL_CAPS is intended for user override and all_lower
is for internal variables. Introduce CC and CXX to enable finer control
over the compiler (ccache, etc.).
The official Vim project no longer hosts older versions of Vim, and the
original Vim host is now gone. Due to the hashes, we can safely download
from anywhere stable, so let's try this mirror.
Now that GGML's version has been bumped from 0.9.4 to 0.9.5, the
hardcoded version in llama.mak is no longer correct. Instead, parse the
version number out of the CMakeLists.txt and retrieve the commit hash
using git if available.
This should cut back on most, though not all, build script updates. The
mtmd subdirectory still requires a manual listing because it only uses a
few files. The generated build info source was moved out of the way so
that it doesn't match globs. It also now builds the llama.dll.a import
library.
See #309. Closes#316.
Go (gc toolchain) does not yet support bigobj, and so cgo is currently
incompatible with w64dk. Bootstrapping Go 1.4 from C still works, but
even that's increasingly impractical anyway.
Also switch to GitHub releases because it apparently not subject to
naive Expat security policies, making it more reliable. Expat only
parses trusted inputs in w64dk, and so is unaffected by security issues.
Updates are generally unnecessary. Unfortunately Expat's repository has
an unconventiontional tagging convention, and tags do not exactly match
the version, so the ARG will no longer work on its own, which is why I
had avoided its GitHub releases for so long.
The widl configure script is broken and does not support out-of-source
builds, so unlike gendef just above, it's built in the source tree. The
--prefix and --with-widl-includedir options must be congruent despite
their artificiality. These two paths are combined to construct the real
sysroot path at run time via tools.h:build_relative_path.
This patch also creates arch-prefixed aliases for both gendef and widl.
llvm-mingw switched to using it in this commit:
https://github.com/mstorsjo/llvm-mingw/commit/a96bbc0c
And I figured we should do the same. Especially since we download more
than just GNU make.
GNU themselves write (https://www.gnu.org/server/mirror.en.html):
> We recommend using this generic ftpmirror.gnu.org address wherever
> possible in links, documentation, etc., to reduce load on the main GNU

One of my goals is that the distribution can be re-built in place using
only Docker or Podman, and so the unpacked distribution mirrors the
repository layout. That hasn't been true for w64devkit.ini, which is the
only file interfering with this trick, so fix it.
