GDB在山狮上失败 [英] gdb fails on mountain lion

问题描述

我试图编译7.x版本的gdb，没有任何运气。
我对可执行文件进行了编码签名（http://sourceware.org/gdb/wiki/BuildingOnDarwin）。

以下版本存在这些问题。

7.5,7.4，git clone：未知的加载命令0x2a（和其他）为我的应用程序和不同的系统库启动gbd时。例如，当我试图打印一个向量时，我总是得到：
找不到main（int，char **）的帧基底

<7.3> macports和gdb-website）：在启动应用程序时，它无法设置断点并继续运行。

 （gdb）启动
 0x100000950临时断点1：文件../src/main.cpp，第15行。
启动程序：[...] 
 BFD：无法读取未知加载命令0x24 
 BFD：无法读取未知的加载命令0x2a 
 BFD：无法读取未知的加载命令0x26 
重新设置断点的错误1：无法访问地址0x100000950处的存储器
 [应用程序继续] 
  

我使用系统llvm-gcc，gcc4.7和svn-gcc4.8来编译。
有没有人成功在Mountain Lion上安装gdb？

解决方案

我在山狮上安装了gdb 7.5，没有问题。 。

1. 这些步骤可以帮助您：./configure --prefix = / usr / local
   --enable -targets = x86_64-apple-darwin10 -enable-64-bit-bfd -disable-werror -build = x86_64-apple-darwin10 -host = x86_64-apple-darwin10 -target = x86_64-apple-darwin10




2. 然后安装gdb。

gdb
http://sourceware.org/gdb/wiki/BuildingOnDarwin



3. 在签署gdb之前，您必须明确声明：codesign -s gdb-cert / usr / local / gdb
   确保您已将证书设置为
   到可信。在签署gdb之前也关闭钥匙串。

希望这也适用于您的

I tried to compile a 7.x Version of gdb without any luck. I codesigned the executable(http://sourceware.org/gdb/wiki/BuildingOnDarwin).

With following version there were these problems.

7.5,7.4,git clone: unknown load command 0x2a (and others) for my application and different system libraries when starting gbd. When trying to print a vector for example i always get: Could not find the frame base for "main(int, char**)"

7.3 (macports and from gdb-website): on starting the application it fails to set the breakpoint and continues to run.

(gdb) start
Temporary breakpoint 1 at 0x100000950: file ../src/main.cpp, line 15.
Starting program: [...]
BFD: unable to read unknown load command 0x24
BFD: unable to read unknown load command 0x2a
BFD: unable to read unknown load command 0x26
Error in re-setting breakpoint 1: Cannot access memory at address 0x100000950
[application continues]

I used the system llvm-gcc, gcc4.7 and svn-gcc4.8 to compile. Has anybody succeeded in installing gdb on Mountain Lion?

解决方案

i installed gdb 7.5 on mountain lion without problems...

1. those steps might help you: ./configure --prefix=/usr/local --enable-targets=x86_64-apple-darwin10 --enable-64-bit-bfd --disable-werror --build=x86_64-apple-darwin10 --host=x86_64-apple-darwin10 --target=x86_64-apple-darwin10

2. then make install gdb.

3. create your own certificate like discribed here and sign the gdb http://sourceware.org/gdb/wiki/BuildingOnDarwin

4. you have to explicitly state: codesign -s gdb-cert /usr/local/gdb before you sign the gdb make sure you already set your certificate to trusted. also close the keychain before signing your gdb.

hope this also works for your
