Hi,
this is the second version of the patch series that modernizes our build
system by introducing Meson. This series is still in an RFC state.
Changes compared to v1:
- I've reordered patches such that the platform-specific patches all
come up front. This allows us to merge them independently of the
rest of this series.
- I've included a couple more fixes to platform-specific issues.
- I've introduced an ICONV prerequisite. Executing tests is currently
broken when compiling with NO_ICONV=Yes, and this prerequisite fixes
that.
- I've upstreamed the standalone patch to the clar framework I had in
v1 for how we typedef `struct stat`, and adapted the commit that
updates clar to update to the newer version that includes the patch.
- I've fixed an issue in "generate-clar-decls.h" when the build path
contains spaces. I found this by accident when I had a spaces in my
source directory on Windows.
- I've rebased on top of Git v2.47.
- I've clarified some commit messages.
- I've updated "build-systems.txt" based on the feedback I got.
- I've made Meson work with the Microsoft Visual Studio compiler.
- I've included subproject wrappers. These are small files that tell
Meson for how to build a dependency as a fallback in case the host
system does not have the dependency. This allows a developer to
build Git without any system-provided dependencies and is quite
helpful especially on Windows.
- Various other small fixes and improvements to Meson.
Overall I've got this to a state where things are mostly working. I've
successfully built and tested stuff on Linux, macOS 10.15, Windows 10
with MSVC, MinGW and Cygwin as well as FreeBSD.
The series is structured as following:
- Patches 1 to 11 provide various fixes to preexisting issues on
several platforms. These fixes can be merged independently of the
rest of this series -- so even if you don't care for the remainder
of it, I'd be happy if those were reviewed.
@Junio: Let me know whether this is good enough for you, or whether
I should split those patches out into a separate series.
- Patches 12 to 22 refactor parts of our build system to make proper
out-of-tree builds a reality.
- Patch 23 introdudces the "build-systems.txt" file.
- Patch 24 introduces the Meson build system.
Thanks!
Patrick

This is broken for MinGW though because "$PWD" will use Windows-style

- a Unix-style path, which we can get by using `$(pwd)` instead.

directory of "t/". While true when using our Makefile, it's not when
using build systems that support out-of-tree builds.
- Allow such build systems to override the location of the build directory
- with an environment variable.
+ In commit ee9e66e4e7 (cmake: avoid editing t/test-lib.sh, 2022-10-18),
+ we have introduce support for overriding the GIT_BIULD_DIR by creating
+ the file "$GIT_BUILD_DIR/GIT-BUILD-DIR" with its contents pointing to
+ the location of the build directory. The intent was to stop modifying
+ "t/test-lib.sh" with the CMake build systems while allowing out-of-tree
+ builds. But "$GIT_BUILD_DIR" is somewhat misleadingly named, as it in
+ fact points to the _source_ directory. So while that commit solved part
+ of the problem for out-of-tree builds, CMake still has to write files
+ into the source tree.
+
+ Solve the second part of the problem, namely not having to write any
+ data into the source directory at all, by also supporting an environment
+ variable that allows us to point to a different build directory. This
+ allows us to perform properly self-contained out-of-tree builds.

-+=== Rust support
++=== Cross-platform builds
++
++The build system should support cross-platform builds, e.g. building for arm on
++an x86-64 host.
++
++=== Language support
++
++The following languages and toolchains are of relevance and should be supported
++by the build system:
++
++ - C: the primary compiled language used by Git, must be supported. Relevant
++ toolchains are GCC, Clang and MSVC.
++ - Rust: candidate as a second compiled lanugage, should be supported. Relevant
++ toolchains is the LLVM-based rustc.
++
++Built-in support for the respective languages is preferred over support that
++needs to be wired up manually to avoid unnecessary complexity. Native support
++includes the following features:
++
++ - Compiling objects.
++ - Dependency tracking.
++ - Detection of available features.
++ - Discovery of relevant toolchains.
++ - Linking libraries and executables.
++
++=== Test integration
++
++It should be possible to integrate tests into the build system such that it is
++possible to build and test Git within the build system. Features which are nice
++to have:
+
-+Many long-time Git contributors are nowadays in favor of adopting Rust as a
-+second language next to C. The build system SHOULD thus support Rust such that
-+we do not have to reopen the discussion once we decide to pick up Rust.
++ - Track build-time dependencies for respective tests. Unit tests have
++ different requirements than integration tests.
++ - Allow filtering of which tests to run.
++ - Allow interactive tests that drop the user into a shell with `test_pause` or
++ `debug`.
