サマリ
特にbuildrootに特化した内容ではなく
buildroot内のpackageが使用しているビルドシステムのエラー回避方法など
内容
pragma
一番基本
warningでエラー停止するので除外する
libglib2はなぜかこんなエラーが発生する
stdio.hをincludeするだけでビルドが止まる

patchのあてかた
patchはpackageディレクトリ内の該当のプログラムディレクトリから
mkファイルに書かれているソースコードをダウンロードしてきて
git管理するのが良い
libglib2の場合
package/libglib2/libglib2.mkが以下のようになっている
LIBGLIB2_VERSION_MAJOR = 2.76
LIBGLIB2_VERSION = $(LIBGLIB2_VERSION_MAJOR).1
LIBGLIB2_SOURCE = glib-$(LIBGLIB2_VERSION).tar.xz
LIBGLIB2_SITE = https://download.gnome.org/sources/glib/$(LIBGLIB2_VERSION_MAJOR)
普通に読み解くと
https://download.gnome.org/sources/glib/2.76/glib-2.76.1.tar.xzが
該当のファイルなので以下のようにする
wget https://download.gnome.org/sources/glib/2.76/glib-2.76.1.tar.xz
tar xf glib-2.76.1.tar.xz
cd glib-2.76.1
git init
git add .
git commit -m "init"
元々存在しているpatchがあるのでそれを当てる
for a in `ls /path/to/buildroot/package/libglib2/ | grep patch `
do
patch -p1 < /path/to/buildroot/package/libglib2/$a
done
git 更新する(origファイルとか出来ても不要なので削除する)
patchが新規ファイルを作成するようになっている場合は削除せず
git add -N xxxなどしておく
git status
# git add -N xxx 必要に応じて
git clean -dfx
git add -u
git commit -m "patched"
後は編集してpatchファイルを作成する
（番号は連番である必要は無いが、順番が関係ある場合もあるので注意）
# vim [ソースコード]など
...
git diff > /path/to/buildroot/package/libglib2/0007-cross_compile.patch
サブモジュールのpatch
サブモジュールはgit diffで差分を取るとcommit-idの差分しか見えない
サブモジュール内で差分を取って、ディレクトリ構成だけ合わせる必要がある
親の差分がある場合だとパッチファイルを分けた方が良い
例) bpftoolの場合
SM=libbpf ##これはSM=libbpf git ... など1行にすると$SMで値が取れないので注意
git diff --ignore-submodules > /path/to/0001-cross_compile.patch
git -C $SM diff | perl -pe "s/ (a|b)\// \1\/$SM\//g" > /path/to/0002-cross_compile_submodule.patch
configure.ac
処理を追加する方法
m4ファイルを作成する
aclocal.m4は自動生成なので新規で作成する
AC_DEFUNで関数名を定義し、[]内に処理を記載する
例) custom.m4
AC_DEFUN([DUMP_VARS], [
AC_MSG_NOTICE([Running custom macro...])
declare -p
])
configure.acで呼び出す
m4_include([custom.m4])
DUMP_VARS
Makefile.amに変数を渡す
configure.ac内の変数を渡す
AC_SUBSTの第１引数に変数名、第２引数に設定する内容を記載する。
AC_SUBST([TARGET_OR_HOST], "$target_or_host")
configureに来た変数を渡す
STAGING_DIR=/path/to/dir ./configureなどで変数が渡されてきた場合
そのままMakefileに渡す方法
AC_ARG_VAR(STAGING_DIR, [Staging directory for cross-compilation])
AC_SUBST([STAGING_DIR])
ちなみにSTAGING_DIRはルートのMakefileでexportされているので
AC_SUBST([TARGET_ROOT_DIR],"$STAGING_DIR")
みたいな感じで変数名を変換したほうが良いと思う。
Makefile.amで条件処理を行う変数を渡す
x11の場合
上と組み合わせて使うと良いと思う
AM_CONDITIONAL(STAGING_DIR_SET, [test -n "${STAGING_DIR}"])
Makefile.am側では以下のように処理する
if STAGING_DIR_SET
CROSS_SYSROOT = --sysroot=$(STAGING_DIR)
else
CROSS_SYSROOT =
endif
AM_CONDITIONALは存在しない場合もある
ソースコード内のm4ファイルをAC_DEFUNでgrepしたら
使用可能な関数がわかります
libtool
ltmain.sh
ビルドにlibtoolが使用されていてltmain.shがソースコード内に存在する場合
ltmain.shがlibtoolに変換される
ltmain.shは単なるシェルスクリプトだがコード量が膨大
また、libtoolに渡された引数は独自の処理が行われて、
実際にgccに渡されるものには変換がかけられる
コンパイル時の処理
func_mode_compileで行う
リンク時の処理
func_mode_linkで行う
引数解析
6800行くらいの以下あたりから
for arg
do
コマンド実行
10000行くらいの以下あたりで$cmdにgccのコマンドラインが入っている
$opt_dry_run || eval "$cmd" || {
cmd="$cmd [追加したいオプション]"
などとやると無理やり通すことができる
とくに-Wl系はMakefileで指定してもlibtoolで弾かれるので
自動patch
なお、ltmain.shはbuildroot側でpatchがされる場合がある
自前patchが先に行われるため、conflictした場合
buildrootのpatchを含めた自前patchを作成する必要がある
patchを作成するのはbuildで止まった場合だと思われるため、
大元のコードを取得し、git管理したあと
buildrootの自動patchが当たった(buildで止まった状態の)ものを上書きする
ここでcommitせずに修正したい箇所を修正すると
自動patchと自前の修正が合わさったdiffが出来る
buildroot側では同じ内容で再patchしないように
自動patchをoffにする

cross-compilation.confにsysrootが書き込まれるが

ビルド
基本的にはV=1をつけるのが吉
エラーが発生したら、エラー発生パッケージを一回きれいにしないと
なんとなくで通ってしまう可能性がある。
make パッケージ名-dircleanでビルドディレクトリごと削除される。
(ダウンロードしたものは別に保存されているので再ダウンロードはされない)
例) libinputでエラーが発生し、configure.acのパッチをおいて再ビルドする場合
make xdriver_xf86-input-libinput-dirclean && make V=1 2>&1 | tee build.log
AUTORECONF
configure.acファイルがあるのにautoreconfが有効で無い場合
なるべく有効にした方が良いと思う。
例) twmでautoreconfを有効にする

24/12/18追記
qemuのvirtで動作確認出来ました。
使用した起動コマンドは以下です。
sudo qemu-system-aarch64 -M virt -cpu cortex-a710 -m 2048 -kernel output/images/Image -device virtio-gpu -display gtk,show-cursor=on -append "root=/dev/vda console=ttyS0" -drive if=pflash,format=raw,file=efi.img,readonly=on -drive if=pflash,format=raw,file=varstore.img -drive file=./output/images/rootfs.ext2,if=virtio,format=raw -netdev tap,ifname=tap0,script=no,downscript=no,id=my_net_id -device driver=virtio-net,netdev=my_net_id -device qemu-xhci -serial stdio -device usb-mouse -device usb-kbd -device usb-tablet -vnc :0
varstore.imgとefi.imgは以下です。
ubuntuだとQEMU_EFI.fdのインストール場所は変わると思いますが
edk2のインストール先にあると思います。
truncate -s 64m varstore.img
truncate -s 64m efi.img
dd if=/usr/share/edk2/aarch64/QEMU_EFI.fd of=efi.img conv=notrunc
-device usb-tabletを追加しないとマウスがプルプルしました。
カーネルのコンフィギュレーションで
CONFIG_DRM_VIRTIO_GPUを有効にして
xorg.confを以下のようにする必要がありました。(ボード名はmenuconfigしたものに変更する)
$ cat board/radxa/rock4cp/overlay/etc/X11/xorg.conf
