wedepend

A DLang dependency tracker, it knows to ignore unittest and version blocks and can help interface into an external build system.

Building

Native build (auto-detects the host OS/arch via uname):

make

Cross-compile for another target triple by overriding TRIPLE:

make TRIPLE=aarch64-linux-gnu
make TRIPLE=x86_64-linux-gnu
make TRIPLE=x86_64-apple-darwin
make TRIPLE=arm64-apple-darwin

make test only works for a native build (TRIPLE unset or matching the host); it refuses to run for a cross target since the resulting binary can't execute on this host.

Cross-compilation prerequisites

Passing TRIPLE= only sets ldc2's -mtriple; it does not by itself produce a working cross-linked binary. You'll also need, for the target triple:

1. A druntime/phobos2 built for that triple (e.g. via ldc-build-runtime), wired in through a custom ldc2.conf with a triple-matched section, passed via LDC_CONF=/path/to/ldc2.conf.

2. A linker/toolchain capable of producing the target's binary format, e.g. lld with an appropriate sysroot, or a wrapper such as zig cc. Wire these in with LINKER=, GCC=, and/or SYSROOT_FLAGS=, e.g.:

   make TRIPLE=aarch64-linux-gnu \
        LDC_CONF=$HOME/.ldc/aarch64-linux-gnu.conf \
        LINKER=lld \
        SYSROOT_FLAGS='-L--sysroot=/path/to/sysroot'
   

See LDC's cross-compilation documentation for building target runtimes and sysroots; this Makefile only provides the override hooks, not the toolchain.
