[PATCH] Makefile: build libgit-rs and libgit-sys serially

From: David Aguilar <hidden>
Date: 2025-08-26 16:04:41

The "cargo build" invocations in contrib/ cannot be run in parallel.

"make -JN" with INCLUDE_LIBGIT_RS enabled causes cargo lock warnings
and can trigger ld errors during the build.

The build errors are caused by two inner "make" invocations getting
triggered concurrently: once inside of libgit-sys and another inside of
libgit-rs.

I'm not familiar enough with make or with rust, but do we need to
depend on both of these here? Wouldn't it be sufficient to say
libgit-rs depends on libgit-sys, and only explicitly depend on
libgit-rs in `all::`?

Not all platforms can build libgit-rs, so inserting it into as a required component is not
a particularly friendly idea.

That's not what I was suggesting. This is already in an `ifdef`, and
the line I was quoting was changing `all:: libgit-sys libgit-rs` to
`all:: libgit-sys .WAIT libgit-rs`. I'm wondering if we can instead
split the `libgit-sys libgit-rs:` from a few lines earlier into
`libgit-sys:` and `libgit-rs: libgit-sys` and then change this all
line to `all:: libgit-rs` (still behind `ifdef INCLUDE_LIBGIT_RS`).

Thank you. I appreciate this and the clarity it provides.
