#[===================================================================[
|
|
Patch executables to run in non-Nix environments.
|
|
|
|
The Nix toolchain links binaries against an ELF interpreter (loader)
|
|
that lives in the Nix store, so the resulting binaries don't run elsewhere
|
|
(including once installed from the .deb package). `patch_nix_binary` resets
|
|
the interpreter to the system default loader and drops the rpath, once the
|
|
binary has been linked.
|
|
|
|
This runs by default for Nix-toolchain builds (determined by whether the compiler resolves under /nix/store/).
|
|
Those builds are where binaries get a Nix-store loader.
|
|
It is opted out of by setting the XRPLD_NO_PATCH_NIX_BINARY environment variable —
|
|
the plain Nix dev shells set it, since their binaries link a newer glibc
|
|
and must not be retargeted to the system loader.
|
|
|
|
Non-Nix builds (a system compiler, already using the system loader) and sanitizer builds
|
|
(runtime libraries resolved through the rpath) are skipped too.
|
|
Everywhere else `patch_nix_binary` is a no-op.
|
|
|
|
The default loader is resolved by bin/default-loader-path.sh.
