# CROSS-COMPILE WORKAROUNDS — packages that fail aarch64 cross-compile
|
|
#
|
|
# These packages need NATIVE COMPILATION on the uConsole itself (aarch64).
|
|
# They cannot cross-compile from x86_64 for various reasons listed below.
|
|
# We work around them in the overlay until we set up distributed builds
|
|
# with the uConsole as a native aarch64 builder.
|
|
#
|
|
# ==== Cross-compile failures ====
|
|
#
|
|
# libcamera / libcamera-rpi / libpisp:
|
|
# meta.platforms excludes aarch64. pipewire hard-depends on them in nixos-25.11.
|
|
# Fix: empty meta.platforms + strip from pipewire buildInputs.
|
|
#
|
|
# gjs:
|
|
# Need native display (GTK3/4 tests) for cross-compile configure.
|
|
# Fix: meson -Dskip_gtk_tests=true.
|
|
#
|
|
# hyprland:
|
|
# Qt6Quick missing from aarch64 qtdeclarative, breaks hyprland-qt-support.
|
|
# Fix: wrapRuntimeDeps=false (Qt UI components disabled, WM still works).
|
|
#
|
|
# boost.mpi:
|
|
# Boost.Build has no b2 architecture alternatives for ARM.
|
|
# Fix: useMpi=false.
|
|
#
|
|
# perl-ldap (perlPackages.perlldap):
|
|
# Module::Install requires Perl dynamic loading (Fcntl) which is
|
|
# unavailable in cross-compiled Perl.
|
|
# Fix: stripped from john.s propagatedBuildInputs.
|
|
#
|
|
# john (John the Ripper):
|
|
# Indirectly affected — depends on perl-ldap for perl utility scripts.
|
|
# Fix: perl-ldap stripped from propagatedBuildInputs (john still works,
|
|
# just loses sha-dump.pl etc. LDAP support).
|
|
#
|
|
# gss (GNU Generic Security Service):
|
|
# autogen.sh fails cross-compile. Pulled by mailutils → emacs-pgtk.
|
|
# Fix: emacs withMailutils=false.
|
|
#
|
|
# emacs-pgtk:
|
|
# Indirectly affected — depends on mailutils which depends on gss.
|
|
# Fix: withMailutils=false (no mail/IMAP within emacs).
|
|
#
|
|
# qtquick3d (Qt6):
|
|
# Qt::Quick not available in aarch64 cross-compile qtdeclarative.
|
|
# cmake skips build, ninja has no install target.
|
|
# Fix: removed js8call, switched wireshark → wireshark-cli.
|
|
#
|
|
# js8call:
|
|
# REMOVED from system packages. Depends on Qt6 multimedia → qtquick3d.
|
|
#
|
|
# wireshark-qt:
|
|
# SWITCHED to wireshark-cli. Same Qt6 multimedia → qtquick3d chain.
|
|
#
|
|
# neovim:
|
|
# `libnlua0.so` built for aarch64, luajit (x86_64) tries to load it
|
|
# during codegen (preload_nlua.lua). No clean override option.
|
|
# Fix: remove from system packages + install via native build
|
|
# once uConsole is set up as remote builder.
|
|
#
|
|
# clamav:
|
|
# cmake try_run() + Rust proc-macro can't find native linker in
|
|
# cross-compile (cc crate uses cross CC, no cc in PATH for build
|
|
# scripts). Chain: clamav → system-path → etc → dbus → polkit.
|
|
# Fix: remove from system packages; clamscan available from server.
|
|
|
|
#
|
|
# ==== Remote builder setup (bidirectional) — TODO ====
|
|
# To eliminate cross-compile exceptions, set up distributed builds:
|
|
# 1. Create a dedicated `builder` user on both hosts (no shell, home=/var/empty)
|
|
# 2. Add the same SSH key to both hosts (symmetric)
|
|
# 3. On lazyworkhorse — `nix.buildMachines` pointing to uConsole for aarch64-linux
|
|
# 4. On uConsole — `nix.buildMachines` pointing to lazyworkhorse for x86_64-linux
|
|
# 5. Remove the uconsoleCrossOverlay workarounds above
|
|
# 6. Nix auto-dispatches derivations by `system` — no per-package exceptions needed
|
|
# Example buildMachines config:
|
|
# Server dispatches aarch64 builds to uConsole (4 cores, less power):
|
|
# nix.buildMachines = [{
|
|
# hostName = "uConsole.local";
|
|
# systems = ["aarch64-linux"];
|
|
# maxJobs = 4;
|
|
# sshUser = "builder";
|
|
# sshKey = "/etc/ssh/builder_key";
|
|
# }];
|
|
# uConsole dispatches x86_64 builds to server (36 cores, 256GB RAM):
|
|
# nix.buildMachines = [{
|
|
# hostName = "lazyworkhorse.net";
|
|
# port = 2424;
|
|
# systems = ["x86_64-linux"];
|
|
# maxJobs = 36;
|
|
# sshUser = "builder";
|
|
# sshKey = "/etc/ssh/builder_key";
|
|
# }];
|
|
|
|
# ==== How to build natively on uConsole ====
|
|
# To native-compile these on the uConsole:
|
|
# 1. Add uConsole as a remote builder (nix.buildMachines)
|
|
# 2. Set nix.extra-platforms = [ "aarch64-linux" ] on server
|
|
# 3. Remove the overlay workarounds below
|
|
# 4. Packages will auto-dispatch to uConsole for native builds
