在 MacOSX 上,lldb 需要进行代码签名。调试和发布版本设置为使用名为 lldb_codesign 的代码签名证书进行代码签名。
If you don't have one yet you will need to:
- Launch /Applications/Utilities/Keychain Access.app
- In Keychain Access select the "login" keychain in the "Keychains"
list in the upper left hand corner of the window.
- Select the following menu item:
Keychain Access->Certificate Assistant->Create a Certificate...
- Set the following settings
Name = lldb_codesign
Identity Type = Self Signed Root
Certificate Type = Code Signing
- Click Continue
- Click Continue
- Click Done
- Click on the "My Certificates"
- Double click on your new lldb_codesign certificate
- Turn down the "Trust" disclosure triangle
Change:
When using this certificate: Always Trust
- Enter your login password to confirm and make it trusted
The next steps are necessary on SnowLeopard, but are probably because of a bug
how Keychain Access makes certificates.
- Option-drag the new lldb_codesign certificate from the login keychain to
the System keychain in the Keychains pane of the main Keychain Access window
to make a copy of this certificate in the System keychain. You'll have to
authorize a few more times, set it to be "Always trusted" when asked.
- Switch to the System keychain, and drag the copy of lldb_codesign you just
made there onto the desktop.
- Switch to Terminal, and run the following:
sudo security add-trust -d -r trustRoot -p basic -p codeSign -k /Library/Keychains/System.keychain ~/Desktop/lldb_codesign.cer
- Right click on the "lldb_codesign" certificate in the "System" keychain (NOT
"login", but the one in "System"), and select "Delete" to delete it from
the "System" keychain.
- Reboot
- Clean and rebuild lldb and you should be able to debug.
That should do it.
[注意:-lldb 在 mac 中用作 gdb。]
