GDB missing in OS X v10.9 (Mavericks)
提问by l'L'l
I went to use GDB in OS X v10.9 (Mavericks), and it's not there. Where has it gone?

# gdb
-bash: gdb: command not found
I also launched Xcode 5.0.1:

gdbhas been replaced by lldb, and is no longer supported. gccand llvm-gccare also gone, replaced by clang.
gdb已被 取代lldb，不再受支持。gcc并且llvm-gcc也消失了，取而代之的是clang。

You can install it on Mavericks with Homebrew.
您可以使用 Homebrew 在 Mavericks 上安装它。
brew install homebrew/dupes/gdb

Thanks I'L'I. I used your ./configure options and worked like a charm. Next step is to tell OS X that we allow GDB to debug. This is done by creating a certificate through the keychain, export it and then sudo codesing -s gdb-cert /route/to/gdb, give credential and we are done.
谢谢我L'I。我使用了你的 ./configure 选项并且工作得很有魅力。下一步是告诉 OS X 我们允许 GDB 进行调试。这是通过通过钥匙串创建证书，导出它，然后sudo codesing -s gdb-cert /route/to/gdb提供凭据来完成的，我们就完成了。

I compiled GDB from the source in Maverics.
我从 Maverics 的源代码编译了 GDB。
I altered the makefile (after ./configure) to suppress some errors that should have been warnings...(added the -Wno-string-plus-int)
我更改了 makefile（在 ./configure 之后）以抑制一些应该是警告的错误......（添加了 -Wno-string-plus-int）
Line 385:
CFLAGS = -g -O2 -Wno-string-plus-int
Line 388:
CXXFLAGS = -g -O2 -Wno-string-plus-int
Don't know if both are necessary.
不知道这两个有没有必要。
But
但
As it turns out the standard version does not support debugging from .app files (as needed for Lazarus apps using the Carbon interface)
事实证明，标准版本不支持从 .app 文件进行调试（根据使用 Carbon 接口的 Lazarus 应用程序的需要）

In my case I got it working on OS X with the following steps:
就我而言，我通过以下步骤使其在 OS X 上运行：
Setup GDB Homebrewexactly like described here http://wiki.lazarus.freepascal.org/GDB_on_OS_X_Mavericks_and_Xcode_5
Then set debugging to Dwarf2: Project -> Project Options..
完全按照此处描述的方式设置 GDB Homebrew http://wiki.lazarus.freepascal.org/GDB_on_OS_X_Mavericks_and_Xcode_5
然后将调试设置为Dwarf2: Project -> Project Options..
If Run/Build hangs upthen restart computer(taskgated or some other process certificate most likely not authenticated), debugging settings back to "automatic (-g)"compile & run(authentication dialog appears & log in), then change debugging settings to "Dwarf2"and it should compile again
如果Run/Build 挂了，然后重新启动计算机（taskgated 或其他一些进程证书很可能未通过身份验证），调试设置回到“自动（-g）”编译和运行（出现身份验证对话框并登录），然后将调试设置更改为“Dwarf2”，它应该再次编译
Try to always stop GDB when if it crashes after a run operation to prevent this authentication failure.
如果 GDB 在运行操作后崩溃，请尝试始终停止 GDB，以防止此身份验证失败。

When I looked MacPorts WAS not yet available for Mavericks, but now it is!
当我看到 MacPorts 还不能用于 Mavericks 时，但现在它是！
Fink still isn't.
芬克仍然不是。
But the standard GDB still does not support debugging .app files.
但是标准的 GDB 仍然不支持调试 .app 文件。
