How to build kernel debug info as separate file?
问题 When we share custom built kernel, It is common to give without debug info. Similar to sudo apt-get install linux-image-$(uname -r)-dbgsym , I would like to create separate debug info file for custom built kernel. Here and here they explained generally. I request to share knowledge on creating separate debug info file for entire linux kernel. For sample program $ gcc -g calc.c $ ls -l total 16 -rwxrwxr-x 1 jeyaram jeyaram 8424 Apr 8 09:44 a.out -rw-rw-r-- 1 jeyaram jeyaram 246 Apr 8 09:32
Does compiling with -g, in itself, degrade performance? [duplicate]
问题 This question already has answers here : How do debug symbols affect performance of a Linux executable compiled by GCC? (2 answers) Closed 3 years ago . (This is a question about gcc and clang, but might apply to other compilers.) If I compile my C or C++ code, and generate debug info using the -g switch, does this in itself degrade performance of the compiled program in any way... (1.) With minimum optimization ( -O0 )? (2.) With maximum optimization ( -O3 )? Note: I don't mean the
objdump/readelf get variables information
问题 I need to get the information about global variables from a compiled c program. I asked a similar question in here. The problem that I have now is that the program where I am trying to extract the variables info is very big and it takes 4 seconds just to get the tree in text ( readelf -w[i] file.out ). Then I have to parse the tree jumping back and forth in order to get to the place that I need. For example if a variable is of type const unsigned char * volatile MyVariable then I will have to
Any Java counterpart for `/usr/bin/strip`?
问题 Is there any tool that can remove debug info from Java .class files, just like /usr/bin/strip can from C/C++ object files on Linux? EDIT: I liked both Thilo's and Peter Mmm's answers: Peter's was short and to the point exposing my ignorance of what ships with JDK; Thilo's ProGuard suggestion is something I'll definitely be checking out anyway for all those extra features it appears to provide. Thank you Thilo and Peter! 回答1: ProGuard (which the Android SDK for example ships with to reduce
What is Debug Info?
问题 I am an intermediate C programmer who is learning his way around. I recently learned using GDB (forced to actually) and also am doing some code using Ptrace. I was browsing through some code on ptrace and came across "DEBUG INFO". I want to know what this means and when should I include this in my code? What are debug info files? I couldnt find much from google and wiki related to this. There is no wiki for that tag too. May be if you can point me to the right direction I can repay by writing
Displaying exception debug information to users
I'm currently working on adding exceptions and exception handling to my OSS application. Exceptions have been the general idea from the start, but I wanted to find a good exception framework and in all honesty, understand C++ exception handling conventions and idioms a bit better before starting to use them. I have a lot of experience with C#/.Net, Python and other languages that use exceptions. I'm no stranger to the idea (but far from a master). In C# and Python, when an unhandled exception occurs, the user gets a nice stack trace and in general a lot of very useful priceless debugging
