I first found something called lds(linker script) file.
And now I am willing to do a test with __attribute__((section)) to make a function stay in a private section. Sounds fun to me.
Part of my source code looks like this
By objdump, I didn't find a section called "my_own".
I am trying to compile a software using a provided sdk. I suspect that the sdk has some mismatch of the platform library, but I am not sure.
The error I got is
Code:
The libidata.so.42 is there in that folder. I guess the file might be in a big endian. Is there a way to check if the libidata.so.42 i have might be a big endian format, rather than little endian?
If my guess is incorrect, This is a c++ code on fedora x86 machine.

I need to compile a program and make it portable to other computers, but it needs some external libraries and I don't want them to be linked dynamically, I would like to compile them as one single executable or at least compile them in the same directory as the main output files. The program is sphinx>, it has its own configure and make scripts. I know I can run g++ with the -static flag, but I don't know how to do this with make or configure. This is the ./configure --help output

I have the following problem. I call a C++ program from a Java servlet by using Runtime exec. The OS is ubuntu and I use Netbeans 7.0 with Glassfish 3.1 web server.The program executes but it does not open and write into a specified file in a specified folder. The same C++ program compiled under Windows opens and writes this file.How can I solve this problem in Linux?
View 2 Replies View RelatedI'm running a simple backup and log script that is cronjobed to run twice a day. So currently, when new data is added to the log, its added to the direct bottom of the log file. However, I would like to have it printed to the very top of the log. The code is attached, I can't quote it in here because I am a new user and the system thinks I have url's in it, when they are just paths.

i am working on this thread: [URL] if it is better to open a file every time i need to write to it or should i keep a file open the whole time and when i am done with the script, close it and sendmail it out?
Or i just thought of this: i could keep concatenating to a string and just sendmail when done.
At the moment I got my md5sum checking working which I write to a text file and see below.
If the md5sum works it will write the output to check2.md5 test.txt: OK
If the md5sum fails it will write test.txt: FAILED
How do I write if statement to check the output whether or not the md5sum failed or not ?
check1="/home/ops/Desktop/test1/check1.md5"
check2="/home/ops/Desktop/test1/check2.md5"
cd /home/ops/Desktop/test1

Write some simple script?
Heres what Im trying to do:
-Qjackctl has a config file which is modified each time QjackCtl is shut down. This means that whatever preset is in use when QjackCtl closes is written into the QjackCtl config file as the DEFAULT PRESET, for the next time QjackCtl starts (or at least this is how I understand it).
-I want to edit a specific line in the QjackCtl.config file, which specifies the DEFAULT PRESET. Obviously its easy to do manually, but I want to do it using a shell script which runs automatically on StartUp so that QjackCtl starts every time with the same DEFAULT PRESET, NOT the last one used.
-Unfortunately Im not at my Linux system right now (which is KXStudio/Kubuntu), but I believe the QjackCtl.config line looks something like this: DEF_PRESET=alsa (where alsa is the name of the preset)
PRESET1=alsa
PRESET2=firewire
I want a shell script which changes the line DEF_PRESET=alsa to DEF_PRESET=alsa, even when it may currently exist as DEF_PRESET=firewire due to occasions when firewire was the active preset when Qjackctl was last closed. I notice that the application in KDE that enables the user to set which applications open automatically on StartUp also allows the user to select shell scripts.
Ive done some research, as a beginner, and Im led to believe I might need to use AWK and/or CHMOD. I could have a go at writing a shell script but Im always wary about experimenting with StartUp scripts/operations because obviously if I get it wrong and make my system unusable, then because its going to run first thing on each boot, Id have great difficulty disabling it.
I have a bash script that checks for contents in a folder every 15 seconds and then acts on it's contents. This works great for the average size file however on very large files it starts acting on the file before it's completely written. Is there a facility in bash shell to get a file complete signal or such? here is trigger to launch a larger script.

I am a novice to the shell script. In my system from db server the log files are enerating with the name log1.txt,log2.txt..... It is capable of keeping 10 files at a time in dir called /db/sis/log1.txt. I want to copy the log1.txt to another directory when ever it generating by attaching the time stamp to it for the back-up purpose. this files will be there for a period of 24 hours. after that the back-up dir should be cleared and it start copying again the fresh file from the same dir.

like my alias a retired person, and Its never to late to learn something½ve just installed Ubuntu and found a tutorial online about bash-script.Manage some, but I cant to this one:[Write a script that makes file executable and writes a message that it has been done.If I run the command > <scriptName> <fileName> , then the file fileName should be executable and then it should indicate that fileName have been executable.]
Ive read man pages up-n-down and search the web, and I think I should let the script use chmod and ls -l, but I cant get the hole picture here. Actually I have nothing to show up, so I hope someone could help me with some ideas or a soloution - just to the how it should look.This is my first post, ever, at a forum like this, so please be nice if I didnt follow any rules here, I dont know if you even will answer this post, but at least give me some clues, a skeleton-code ti be based on
Something very handy to do in a Linux shell, is manipulating files and strings - essentially parsing data. Write a utility which will scan in a text file and search and replace strings. We also want to keep track of how many strings we've replaced.
I know that my command would look like this: <utility name> <filename> <stringToSearchFor> <stringToReplaceWith>
