Programming :: Make File Debugging Racking?
Feb 24, 2010
I have an environment where i have recursive make files (that is one main and in each directory of a project a file.mk with rules for that directory).Since i'm not the one who wrote it i'm not familiar with it. I would like to explore when i run certain targets how the rules work, which files cause dependency rules to work and why. Also i would like to know ALL the targets that are available to me. i couldn't find any way to 'debug' makefiles or to put it in such debug mode that i see all the information i need when i run a certain target.

Does anyone know how can one improve his debugging skills or how can one narrow down the problem and try to get to the solution ASAP.Or rather how once should approach a problem.I know this is a bit vague question but I want to know how you people approach?

i need to debug a application which is using many threads. i am using eclipse with GDB debugger but it is not possible to debug it since it has a lot of different threads and i can not not debug it as wre debug in case of single thread(main) . So i would like to know, is there a way to debug such an application, if there is some tutorial that would be nice to know.

I'm running gdb across a network using gdb server. I've got it up and running. However I can't see any source or variables for my code (in ddd /gdb). At start up gdb says (no debugging symbols found). I've got a g in my make file,
CPFLAGS = -Wall -Os -g -pedantic
I've tried loading symbols in using "symbol-file testarm", this sort of works in that I can view symbols but not names, e.g. if I ask dd to show x y and z, rather than
x = 10
y = 20
x = 30
It says:
display
10/20/30
Also ddd does not show anything in the source window, is there a way I can get it to show this? I think it's because I've started ddd with ddd arm-linux-gdb, as I'm calling a crosscompiler gdb. So can I tell ddd to point to the correct folders? What commands I need to set in gdb/ddd to view variable names (it's hard to keep track when it bunches them all together) and how to view my source code.

A thread-aware version of gdb receives a system notification when a thread starts in the app it is debugging. GTK+ has hidden threads associated with loading icons into menus. So trying to debug a GTK+ program, even one that is apparently single-threaded, can produce a deadlock between gdb, the app and XWindows. The app (actually GdkPixbufLoader) grabs the focus, the mouse and the keyboard and then starts a thread when a menu is opened. If gdb has trouble with threads, it leaves the app blocked but still holding the mouse, et. al. Then you can't talk to gdb or any other GUI interface. To make gdb happy, all GTK+ apps need to be linked with -pthread, if you have the source. If not, gdb cannot be used. In order to break the deadlock, you need a non-GUI shell. If your /etc/inittab starts agetty, mingetty, or the like, and you can get to it with <CRTL><ALT><F3...F6>, you can do a kill -KILL <pid> on the offending app, recover and then go back to XWindows with <CTRL><ALT> <F1/F2>. Otherwise it's reboot time.

I need to debug "ls". I downloaded coreutils and compiled them in debug mode."ls" uses readdir() kernel API to fetch files/directories from a file system. readdir() fetch data from any file system (suppose FAT or ext3).I have debug version of FAT/ext3 and installed, I also have debug version of coreutils (ls) as well.Now I want to debug from "ls" to "FAT/ext3 readdir()".How to do that?

I found on the Internet a rough suggestion to debug code which says to add a line:
An example shows this lists the lines of source that do work.
I do not know where these lines are supposed to go and whether the "notdeadyet" should be a call to a subroutine or what. I only found that "%define" is used to link to external files, so I am confused because what I tried did not work.
(I am unable to use (and learn) any debugging tool for another few weeks and I'd like to progress on this If I can.)

So the problem is, when the control come to exec , the exec process is executing at a time... I could not debug the exec. process... error is stack curruption due to same frame So, is there any way to debug the exec process

I have started to work with c++ and autotools.
I mainly maintain an application and a shared library as a hobby.
Nothing professional yet, because I want to understand the best practice strongly recommended by advanced professional programmers.
I check out my sources into $HOME/repository and svn creates:
Where I get c++ sources/headers + configure.ac and Makefile.am
Now I need to understand what is considered as a good practice for debugging application, either A), B) or something else.
A) install application and its dependency with:
or
B)
And then I debug the application in the place it was built. [$HOME/repository/app/src/]

What I am trying to accomplish is a way to read only the lines that have been added to the file mylog0 since the last time the script looped (5 seconds). I am open to new suggestions too, I have been stuck on this little script for a few hours already.
Code: #!/bin/bash

I wasn't sure where to put this so if I need to move it just let me know.I have a strange problem that I cannot figure out. When I use gdb to debug our rpm-installed program, it says (no debugging symbols found) when it loads. Thing is, when I use nm on the program it can print the symbols, and even stranger is if I use gdb on the program before it is packed up by rpmbuild it loads the debug symbols just fine.Our program is built via the standard make using:GS=-g -Wall-pedantic and as I mentioned I can debug the resulting program. After the build, I package it up using:
cmd="rpmbuild -v -bb ptsnmp.spec --define "ver ${cmvc_release}" --define "rel ${cmvc_level}" --define "_topdir $rpmdir""When this package is installed via rpm, the binary on the machine shows all the debug info via nm, file shows it is not stripped:pt_snmp: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not strippedyet when I try to debug it I get the no debugging symbols found.This is really taxing my brain and I am sure I am just missing something

I don't have any problem when I'm communicating with one client. The problem starts when I connect another client.The server eventually ignores the older clients and responds only to the latest one.The working mechanism is simple: Accept connections and print messages received from multiple clients.

Initially I thought - use a for loop with ls in it:
Code:
However this causes lots of problems (folders have extensions, I have duplicate folders, the names with spaces create a folder for each element of the name).
The contents of the folder is basically movies (some with subtitles). Some of the names have things like (original) or CD1 CD2 in them.

Been trying to setup my xorg.conf file to have a 1920x1200 screen.Strange behavior: when my X starts up, I see my mouse cursor, can move it around. It's small enough to suggest the 1920x1200 resolution took, is working.However, the rest of the screen remains black. No login prompt.I've looked at /var/log/xorg.conf, no errors.Is there something else I can look at?

I have a bit of a problem and the only solution I can think of at the moment is a very tedious one, so I was hoping there would be a better way. What I am trying to do is cross compile the PPPD program so that I can install it on an embedded system (this system does not have make/gcc on it). It was easy to cross compile it, but I can not run "make install" since I'm compiling on a secondary machine. I don't want to install PPPD on this secondary machine (I couldn't anyway, because it was compiled for a different architecture) and I can't run make install on the target machine because there is no make/build system for it.
So it seems like what I would have to do is to manually copy over each compiled file from the build machine to the appropriate location of the target machine. And the only way (that I know of) to figure out how to do this is to manually examine the Makefiles (yes, there are several for PPPD) and figure out which file should go where on the target system. This isn't trivial because it uses a hierarchy of makefiles and the probability of human error for this method is high.
Is it possible that I could run another command that would give me a list of all the commands that make install would perform? Or a list of all files and their target location for "make install"? Or possibly some other solution that I am completely unaware of that would make this task not so painful and error prone?

I am trying to compile a C++ source file into a static library using make with root privileges (i.e., using "sudo"). However, I "sometimes" get the following compilation error:
Code:
g++ -Wall -g -fPIC -W -c /home/project/ether/src/packet-ethernet.cc
ar -cvq libether.a /home/project/ether/src/packet-ethernet.o
ar: /home/project/ether/src/packet-ethernet.o: No such file or directory
make: *** [libether.a] Error 1
I checked /home/project/ether/src folder to see if packet-ethernet.o in fact does not exist, and saw that it is actually located there, but its owner is "root", which is different from the current user. If I change the owner of packet_ethernet.o from root to the current user using "chown" command and execute make again with sudo, everything seems to be fine.
It may be a coincidence that I recently migrated to 64-bit platform from 32-bit, and then installed libboost-filesystem1.40-dev. After that, I began to experience such errors. I have "never" come across such a compilation error before. Even though I completely removed libboost-filesystem1.40-dev afterwards to see if it causes the problem, nothing changed.
After migrating to 64-bit and installing libboost-filesystem1.40-dev, my application exhibited another "weird" behaviour such that it produced "hidden" files using mkdir() system call, which were previously created as regular ones on the filesystem. Can compiler options that I use cause such problems? Is it possible that libboost-filesystem1.40-dev overwrote some system libraries so that I am getting such errors ?

My assessment is making a tree from a text file as follows: -reading a file line by line
-making a binary tree from it
- traverse by level the binary tree
- posting the traversal result to the same file without overwriting the text file- it is required to be append to the bottom of the text file (i have to do this in 4 languages: c#,PHP from Xampp,java, python)
i read the file with this script in java:
public class FileToStringArray {
privateString strLine;
privateString[] stringArray;
privateFileInputStream in;

I would like to create a code that is working on windows XP. I would like to have it like visual basic or very simple so that I can run some execlp, exec, or command="program.exe parameters" with also some internet support?GCC ? G++ ? but those require some DLL to be installed on any PC before running; it is for a friend to simplify his operations

Player-Stage uses .cc files. I know how to compile them. But how do I actually execute my code? There is an output file generated. There is nothing in the .cfg file or in the .world file that specifies what program to use to run the robot. Or is it not specified in the world or cfg files?
Then how to make the robot obey my compiled .cc file? If this question is silly or if I am asking stupid questions

When I try to compile some Java code on Ubuntu 10.10 (kernel 2.6+) using make and a Makefile.
I get an error indicating that the make utility cannot execute the java compile command (javac).
The error reads: /bin/bash: line 6: .: /usr/local/jdk1.5.0_18/bin/javac: cannot execute binary file
I am executing make as root. I have enabled permissions on all directories in the path /usr/local/jdk1.5.0_18/bin/javac and on javac itself.
I get this error whether using a jdk installed via ubuntu apt-get, or whether I install the jdk myself. And I get it using either Java 1.5 or 1.6
My machine has an 80386 processor. I notice the make utility is built for i686-pc-linux-gnu
However, I can manually compile using javac.
I can compile calling javac from within a bash script.
I can compile using the java compiler gcj from the command line: gcj --main=HelloWorld HelloWorld.java -o HelloWorld.exe
But I cannot compile java code from the makefile. Any reasons why I might be getting this error?

I wanted to know how can I cross compile SMS SERVER TOOL for an embedded computer and make just one binary file for it or how can I change all of its default files places like its demon and object file and gather all of them to one directory to execute and use and run.let me explain it better for you : I have an embedded computer with Linux OS that its file system is read only and I can not add any file to /usr /lib and ..... and I can just mount a SD memory card to it and copy all of my programs to it and run them from there as you understand I have two choices to choose, first make one big binary file for each program that I am doing it now and it is not a suitable solution and the second is finding the way to change default place of shared object file of my program.now you tell me what can I do to solving this problem.

I want to gave much details as possible. working directory (~/a1/shell) in the shell directory i have Makefile. also in the shell directory i have subdirectory's (obj, src, include)
My current Makefile
Quote:
#What needs to be built to make all files and dependencies
clean:
# End of Makefile
I wanted it so: all .o files are created in the obj subdirectory, and my application, sshell, is created in the shell directory.
I am getting this error when i run the make run: No rule to make target 'shell.h', needed by 'shutil.o'. stop

I been using linux for a while, but I havent had the time to really learn it. Something Id like to get more familiar with is bash so here is a simple example of something I would like to do:
I have a directory full of files. For each file in the directory create a new subdirectory with each files name.
I tried this:
#im already in this directory
aaa=./*
for a in $aaa
do mkdir $a
done
One of the problems is that there are spaces () and - in the filenames so I get many subfolders with names like "-" which i don't want.
I tried stuff like:
aaa=./*
for a in $aaa
do mkdir "'"$a"'"
done
This of course also did not work.
Additional I tried just creating a folder with the name of one of the files and I got this:
mkdir: cannot create directory `(audio) - R56339.EXE': File exists
Well yeah a file exsists with that name, but I want to create a folder- why is there a conflict?
Just to be clear here are the contents of this folder:
~/Desktop/LAB/Media/Drivers - (Image Deployment)/Optiplex_GX260/XP> ls
(audio) - R56339.EXE (NIC-Onboard-Intel) - R54402.EXE
(Modem-datafax-V92) - R54403.EXE OEM_Applications
[Code].....
