Re: git compile with debug symbols
A quick look at the Makefile shows that -g is enabled by default. so debugging is enabled by default On Tue, Mar 4, 2014 at 9:16 PM, Mahesh Pujari pujarimahesh_ku...@yahoo.com wrote: Hello, I am trying to compile git with debug symbols and failed to do so (basically I am a noob), can some one direct me to links or mailing list (have searched but couldn't find) or doc's so that I can debug git using gdb. thanks, mpujari -- To unsubscribe from this list: send the line unsubscribe git in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line unsubscribe git in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Re: git compile with debug symbols
Thanks David for the reply. I think I need to do more ground work of going through how to use gdb. Basically I am java programmer and I was trying out to debug git source using eclipse CDT and as we do in java, I was trying out to set break point but failed with errors as No line 396 in file help.c. And using gdb too I end up with same error. # (gdb) break help.c:396 # No line 396 in file help.c. Am I missing something. thanks, mpujari On Tuesday, March 4, 2014 9:34 PM, Matthieu Moy matthieu@grenoble-inp.fr wrote: David Kastrup d...@gnu.org writes: Mahesh Pujari pujarimahesh_ku...@yahoo.com writes: Hello, I am trying to compile git with debug symbols and failed to do so (basically I am a noob), can some one direct me to links or mailing list (have searched but couldn't find) or doc's so that I can debug git using gdb. git is compiled with debug symbols by default. ... but: 1) some Git commands are shell-scripts, on which you can't use gdb. 2) some Git commands fork other commands, and then you have to deal with multiple processes (i.e. putting a breakpoint in a piece of code executed by the subprocess won't work if gdb is running on the other one). -- Matthieu Moy http://www-verimag.imag.fr/~moy/ -- To unsubscribe from this list: send the line unsubscribe git in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

It seems like you are indicating a function header. That's not code. Either take the function _name_ rather than a line number (that's usually most reliable) or take the first line of actual code. -- David Kastrup -- To unsubscribe from this list: send the line unsubscribe git in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I think that the problem is either your symbols are not loaded. Nevertheless I will walk you through the steps. $ git clone https://github.com/git/git $ make $ gdb ./git $(gdb) gdb break help.c:396 Breakpoint 1 at 0x80f8b40: file help.c, line 396.

Re: git compile with debug symbols
Hello all, Thanks for replying back, figured out (offcourse had to search in net) that 'gdb' version I had was 6.7.1 (OS Ubuntu 12.04 LST), not sure how I got this. Then I upgraded gdb to version 7.4-2012.04 and things got going. thanks, mpujari On Tuesday, March 4, 2014 10:13 PM, David Kastrup d...@gnu.org wrote: Mahesh Pujari pujarimahesh_ku...@yahoo.com writes: Thanks David for the reply.
