Gdb fails in mountain lion

Question

I tried to compile gxb 7.x version with no luck. I encoded an executable file (http://sourceware.org/gdb/wiki/BuildingOnDarwin).

The next version had these problems.

7.5.7.4, git clone: ​​unknown boot command 0x2a (and others) for my application and various system libraries when gbd starts. When I try to print a vector, for example, I always get: Could not find the frame base for "main (int, char **)"

7.3 (macports and gdb-website): when the application starts, it cannot set a breakpoint and continues to work.

(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 llvm-gcc, gcc4.7 and svn-gcc4.8 systems to compile. Has anyone succeeded in installing gdb on Mountain Lion?

Answer 1

I installed gdb 7.5 on a mountain lion without any problems ...

• these steps can help you: ./ configure --prefix = / usr / local --enable-target = 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

• then install gdb.

• create your own certificate as described here and sign gdb http://sourceware.org/gdb/wiki/BuildingOnDarwin

• you need to explicitly specify: codesign -s gdb-cert / usr / local / gdb before signing gdb, make sure you have already installed the trust certificate. also close the keychain before signing your gdb.

hope this also works for your

I solved this problem by following these steps: http://coding.derkeiler.com/Archive/Ada/comp.lang.ada/2012-09/msg00305.html

Steps

• sudo chgrp procmod / usr / local / bin / gdb
• sudo chmod g + s / usr / local / bin / gdb
• Edit /System/Library/LaunchDaemons/com.apple.taskgated.plist and add the + p argument to the job process
• force kill the given process (it will restart)
• Try again

this does not work for me ... the same problem as in the default settings of homebrew

 v1:src zeph$ brew install gdb ==> Downloading http://ftpmirror.gnu.org/gdb/gdb-7.5.tar.bz2 Already downloaded: /Library/Caches/Homebrew/gdb-7.5.tar.bz2 ==> ./configure --prefix=/usr/local/Cellar/gdb/7.5 --with-python=/usr --with-system-readline --enable-targets=x86_64-apple-darwin10 --enable-64-bit-bfd --disable-werror --build=x86_64-apple-darwin10 --hos ==> make ==> make install ==> Caveats gdb requires special privileges to access Mach ports.

k, I had to re-sign it after it SHOULD GET a certificate for all sections.

codeign -fs gdb-cert / usr / local / Cellar / gdb / 7.5 / bin / gdb

Answer 4

There were two questions in the OP question. The issue of signing an executable file or changing a task and using setgid procmod was considered. The second problem is warnings about unknown boot commands. I came across this too, and after a bunch of searches came up with the following fixes, fix this:
