[mac 10.14.4 gdb安装 tips]macOS Mojave: How to achieve codesign to enable debugging (gdb)?

安装常规教程代码签名之后，gdb仍然提示：

Unable to find Mach task port for process-id 39847: (os/kern) failure (0x5).\n (please check gdb is codesigned - see taskgated(8))

This is related to codesign entitlements. you must add "com.apple.security.cs.debugger" key in signing process.

for example you must change codesign -fs gdb-cert /usr/local/bin/gdb to codesign --entitlements gdb.xml -fs gdbcert /usr/local/bin/gdb .

gdb.xml content must something like following code.

<?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>

OK，gdb！
