I wrote a c++ program but for security reasons I need to make sure that no one can read my codes by my ".out" files. I did everything I could. But everyone can see it by "strings Alpha.cpp".I heard that g++ has some options to do so.

in case you have been wondering how some websites hide the exact location of a file on their filesystem, just thought i'd share it with the commnity at large in case someone else is looking for something like this.i take no responsibility for how it is used.
View 4 Replies View RelatedIn a project I'm working on with a few other people, I got the task of writing an assembler. The last thing I do is convert the commands into a binary representation, and jam it into a file. Now one of my teammates said he'd like to be able to "reference" the code within another program. He said he'd be able to do this if the file I output is a Linux object file. I'm thinking it'd also work as an executable. Anyway, he said he'd like to be able to grab the file and reference the binary by address. I'm still fuzzy on this, and if you're confused with what I said here, please tell me so I can ask him for better details.Anyway, I'm aware that gcc can compile files to ".o", but that's only for C/C++, and my file is just binary. I'm also aware of "ld", but I haven't seen any use of it to help me. I'm happy to hear suggestions as to what I can do. If anything, I think I'll implement a few functions to grab the bits and hand them to him in an array or something.

I am running into a snag on .exe files in Lucid. I have Wine installed, but I can not open the file as it is blocked from executing with a window popping up telling me that this file was blocked due to security reasons. I go into the files properties and try to change the permission but that does not help. Is there a way to get around this? Possibly in the terminal as root?

View 4 Replies View RelatedOne of the feature in my application involve changing of hardware setting. This require the user to be root or have administrative right.Before my application enable that feature, I want it to check whether the user is "root" or not, or whether user use "sudo" command to run the application or not, or whether the user has administrative rights or not.What are the codes or library that can do this?
NOTE: Sometimes, advanced linux user may set the user id of root to something else other than 0. So, getuid() may not be helpful in this case.
I need a script that can print some series of strings in colors based in the information of a file, for simplicity let's say it only does:
Code:
#!/bin/bash
printf "e[1;31;32m%-10se[00m" "OK"
When you execute this in the command line it prints a bold green 'OK'. So far so good.
Now, I need to check the output of the script over time using the command watch. The problem then arises. watch seems to ignore the escape codes and just prints:
Code:
[1;31;32mOK [00m
Is there any way to fix this?
If not, how can I check inside the script if it is being executed from a command? (watch in this case) So I can print without color for those cases.

I'm maintaining a c++ application running on a 64-bit RHEL5 server w/32GB ram, but compiled to be a 32-bit executable with g++. The application handles large amounts of data, and has lately been throwing a st9bad_alloc exception. "top" shows the application as dieing right around when VIRT=~3GB, SWAP=~1.5GB and RES=~1.5GB. In the core dump I can see that it's consistently failing to push_back() a piece of data onto a std::vector (which already has hundreds of thousands of objects in it).
I know 4GB is the maximum address space for 32-bit applications. I've learned from this lwn article that a 32-bit kernel reserves 1GB of address space, leaving 3GB for user space. However I'm not running a 32-bit kernel, so that really doesn't answer anything.I wrote a dummy app which called malloc() over and over in a for loop, and it is able to allocate right up to the 4GB before it fails. I don't understand why this one seems to be able to allocate more.
The only difference between the two apps (besides malloc vs std::vector:ush_back), is that the 3GB crashing application attaches to 512mb of shared memory.Anyone have any ideas why this application would be crashing at 3GB? Is there any more diagnostics I should be doing? I would ultimately like to port this to 64-bit for a number of reasons, but it is a big undertaking for my organization, and I'd like to better understand what's going on here.
