关于gdb:mac-OS-GDB-调试golang环境

发现问题

gdb 调试时 golang 时

go build -gcflags "-N -l" -ldflags=-compressdwarf=false gdb/main.go

呈现

gdb please check gdb is ** - see taskgated()

环境及现有配置

解决问题

1. 执行以下一个脚本

#!/bin/bash

# This script is copied from https://github.com/llvm/llvm-project/blob/master/lldb/scripts/macos-setup-codesign.sh

CERT="gdb_codesign"

function error() {
    echo error: "$@" 1>&2
    exit 1
}

function cleanup {
    # Remove generated files
    rm -f "$TMPDIR/$CERT.tmpl" "$TMPDIR/$CERT.cer" "$TMPDIR/$CERT.key" > /dev/null 2>&1
}

trap cleanup EXIT

# Check if the certificate is already present in the system keychain
security find-certificate -Z -p -c "$CERT" /Library/Keychains/System.keychain > /dev/null 2>&1
if [$? -eq 0]; then
    echo Certificate has already been generated and installed
    exit 0
fi

# Create the certificate template
cat <<EOF >$TMPDIR/$CERT.tmpl
[req]
default_bits       = 2048        # RSA key size
encrypt_key        = no          # Protect private key
default_md         = sha512      # MD to use
prompt             = no          # Prompt for DN
distinguished_name = codesign_dn # DN template
[codesign_dn]
commonName         = "$CERT"
[codesign_reqext]
keyUsage           = critical,digitalSignature
extendedKeyUsage   = critical,codeSigning
EOF

echo Generating and installing gdb_codesign certificate

# Generate a new certificate
openssl req -new -newkey rsa:2048 -x509 -days 3650 -nodes -config "$TMPDIR/$CERT.tmpl" -extensions codesign_reqext -batch -out "$TMPDIR/$CERT.cer" -keyout "$TMPDIR/$CERT.key" > /dev/null 2>&1
[$? -eq 0] || error Something went wrong when generating the certificate

# Install the certificate in the system keychain
sudo security add-trusted-cert -d -r trustRoot -p codeSign -k /Library/Keychains/System.keychain "$TMPDIR/$CERT.cer" > /dev/null 2>&1
[$? -eq 0] || error Something went wrong when installing the certificate

# Install the key for the certificate in the system keychain
sudo security import "$TMPDIR/$CERT.key" -A -k /Library/Keychains/System.keychain > /dev/null 2>&1
[$? -eq 0] || error Something went wrong when installing the key

# Kill task_for_pid access control daemon
sudo pkill -f /usr/libexec/taskgated > /dev/null 2>&1

# Exit indicating the certificate is now generated and installed
exit 0

2. 创立 钥匙串

钥匙串拜访 - 证书助理 - 创立证书 - 名称临时为 gdb-cert,勾选☑️然我笼罩这些默认值

一路点创立,到了这个地位选 零碎

3. 执行

security find-certificate -c gdb-cert

4. 信赖 钥匙串

右击第二步创立的钥匙串,改为 始终信赖

5. 验证是否被信赖

如果呈现刚刚的 gdb-cert,代表一切顺利

security dump-trust-settings -d |grep gdb-cert

6. 进行代码签名

  1. 创立一个 xml 文件,gdb-entitlement.xml. 留神名字对齐
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>com.apple.security.cs.debugger</key>
    <true/>
</dict>
</plist>
  1. 执行命令
codesign --entitlements gdb-entitlement.xml -fs gdb-cert $(which gdb)

6. 重启电脑

7. 离胜利很近了

再次 gdb 查看, 须要验证一次明码

而后

其实你看这里更分明了
