  • terminal.appをx86_64用とaarch64用に複製した方が楽な気がするが，Ventura以降は不可能な模様．
  • rust-gdbを動かすためにgdbが必要．brew install gdbで入れる．
  • rust-gdbを動かすためにpythonも必要．現在aarch64用pythonを使ってしまっているので後で修正する

rustup-initで書き換えられるfile(default path?)

$HOME/.profile
$HOME/.bash_profile
$HOME/.zshenv

rust-gdbを実行すると以下のerrorで動かない．適当にググるとptrace関係っぽいことが書いてある．調査中．上記python設定の問題があるので要検証

(gdb) r
Starting program: /Users/ultimatile/programming/Rust/zero_rust/dbg_target/target/debug/dbg_target 
Note: this version of macOS has System Integrity Protection.
Because `startup-with-shell' is enabled, gdb has worked around this by
caching a copy of your shell.  The shell used by "run" is now:
    /Users/ultimatile/Library/Caches/gdb/bin/zsh
Unable to find Mach task port for process-id 87475: (os/kern) failure (0x5).

Rust環境のinstall先を変更

export "CARGO_HOME=$HOME/x86_64/.cargo" 
export "RUSTUP_HOME=$HOME/x86_64/.rustup"

x86_64は別の名前にしても良い．

ryeのinstall

curl -sSf https://rye-up.com/get | bash

brew install ryeも使えるが，環境変数の設定や他の設定ができないっぽいので非推奨．(.ryeも作成されない？)

brewでgdb入れたときの出力よく見たら

gdb requires special privileges to access Mach ports.
You will need to codesign the binary. For instructions, see:

  https://sourceware.org/gdb/wiki/PermissionsDarwin

とちゃんと書いてある．．．

脚注

  1. openssl x509 -in /dev/stdin -checkend 0がopenssl x509 -checkend 0だとWarning: Reading certificate from stdin since no -in or -new option is givenというwarningが出る．結果は変わらないので気にしなくても良い．

(gdb)rすると

During startup program terminated with signal SIGTRAP, Trace/breakpoint trap.

と出て動かない

chmod 755 $(which gdb)
chgrp admin $(which gdb)

をすると上述のerrorは出ないが止まったままshellが帰ってこない

ultimatileultimatile

新しいshellを立ち上げるとまた出るので毎回やるか.zshrc入れる必要がある？

ultimatileultimatile

code署名を完了しても色々

warning: can't find symbol '_ZN108_$LT$nix..sys..socket..addr..sys_control..SysControlAddr$u20$as$u20$nix..sys..socket..addr..SockaddrLike$GT$8from_raw17h0b262d3dbad4b6cdE' in minsymtab

みたいなwarningが出て動かない
https://github.com/rust-lang/rust/issues/40787
libか何かのpathが解決できていないっぽい？

ultimatileultimatile
rust-gdb ./target/debug/deps/[program_name]-[randome_string]

でいけるみたいなやつが書いてあり，確かにWarningは消えるがhang upしてCtrl-CもCtrl-Dも受け付けなくなりkillするしかなくなる．
issueの最初に書いてある例でも動かないので別の問題？
