Programming :: Test App That Scans For Plugins In A Directory?

Aug 27, 2010

I wrote a test app that scans for plugins in a directory, calls their getWidget() method (implemented in my interface), and adds that widget to a layout.

The problem is that when I added a QTimer to my plugin class, it didn't work! Why?

And will it be easier to write the thing in Python and not use QPlugin? I just want to define a QWidget and have it added to the app.

General :: Dynamically Create/delete Device Nodes By Driver?

Apr 15, 2010

I'm a starter here in linux, I have written a driver code and in that, I register my character devices by passing 0 for the major number.

To set up I used to use mknod command from terminal to create node,

Is there any method to create node dynamically from driver code during initialization and delete them at cleanup time?

Programming :: Dynamically Loading Libraries In GNU?

Oct 22, 2010

This post isn't really asking for a tutorial, but rather asking for some ideas. I've come up with a few ideas, but they seem cumbersome and unnecessary, so I was wondering if someone with more experience than me could out. Also, my explanations suck, but I'll try to do my best. So say I have an executable called X. At some point during its execution, X loads and uses (using dlopen and dlsym) a library called Y. In Y, there a bunch of functions that call the function called, for example, void *special_malloc (size_t). These functions come from another linked library (linked during compilation) called Z. Problem is, special_malloc contains some static variables within its scope, and when those variables are reset midway through a program, an invalid free occurs (special_malloc uses garbage collection). Now, what I want to happen is that whenever lib Z calls special_malloc, it instead calls the special_malloc defined in the executable X, so that these static variables are retained. Keep in mind that I have control of the Z library, meaning I can edit the source to fit my needs.

Programming :: Java : Use Dynamically Loaded Classes?

May 15, 2010

I'm new to Java.
I'm trying to use some dynamically loaded classes in my application.
The application doesn't know those classes , Just it try to load a class by name that its name came from input.
It doesn't know class (So I can't use casting) but just needs to call some methods of that class (every class should have that methods).
I thought about interfaces but I don't know how.
How can I call those methods?

Programming :: Link One Library Statically Others Dynamically - Gcc - G++

Jul 6, 2011

I would like to make gcc to link one lib (pthread in the example) statically, and the rest dynamically.

(See the example .c file at the end of this post.)

compiles fine, but every lib is linked dynamically.

Now every lib is linked statically

Not a dynamic executable

I would like to link the libpthread statically and the rest dynamically. Is it possible?

[url]says if I give the full path to the .a lib then it will be linked statically:

So for me it does not work.

On other sites I found that I should use -Wl,-Bstatic -lpthread -Wl,-Bdynamic, but it also doesn't work:

So, how can I do that?

Machine: Linux #1 SMP Mon Jul 28 13:06:32 UTC 2008 i686 i686 i386 GNU/Linux SLED 10

As an example I used a little demo program from [url]

Programming :: Dynamically Supply Input To Netcat In A Script?

Mar 5, 2010

I am trying to write an irc bot to run interactive fiction games in a channel. I am connecting to the channel using nc. I'm having a hell of a time trying to supply input stdin for nc after the connection is established. Here's what's going on. I've got lines of plain text in a file with the irc commands required to identify the bot's ID and join the channel. I can connect easily using any of the following commands

cat inputfile | nc 6667 -i 1
nc 6667 -i 1 < inputfile
Named_Pipe | nc 6667 -i 1
cat inputfile > Named_Pipe

With the first two commands nc connects, reads the file with some time between each line allowing the irc server to respond, bringing me into the channel. It then begins to receive stdin from the command line allowing me to do things like "privmsg #channelname :Hello World!!!" sending messages to the room. This is not the desired behavior. I require nc to take additional stdin from the inputfile if I cat additional text to the end of it.

The last set of commands using the named pipe seem like it does the same, but it doesn't actually send anything to the room, which indicates to me that perhaps nc is continuing to take stdin from the named pipe (this is the desired behavior) rather than dropping to the console for stdin. If I try to cat more plain text data to the end of the named pipe, however, either with something like "echo 'privmsg #channelname :Hello World!!!' > Named_Pipe" (or >> instead of >) or with a filename in place of the "echo" command the whole command simply seems to hang until I press ctrl-C.

I don't understand what I'm doing wrong. With anonymous and named pipes, and with redirection, the problem seems to be the same. nc seems to take it's stdin from the file until it hits the end of file, at which point I can no longer introduce new lines of plain text as stdin for the running nc process.

Programming :: Local Dynamically Allocated Array In Fortran?

Oct 19, 2009

I (my friend) have a fortran program with the code along the following lines:


REAL, DIMENSION(4000,4000) :: a, b, c

The problem is that the huge matrices are retained in memory even after the subroutine ends. Is there an easy way to declare the arrays in a sort of dynamic way, like they were in the following C example?


void ny(void) {
double a[4000,4000];

I mean in the C example the memory is released as soon ny() exits.

Programming :: Unable To Dynamically Create An Array Of Params For Execv In C

Jan 6, 2011

I haven't programmed in C for a while, so I am trying to remember certain aspects of syntax. I have a program that will fork and exec other programs. Those programs will be specified on the command line as follows:

./main "prog1 arg arg ..." "prog2 arg arg ..."

Here is the main snippet:

int countChar(char* s, char c)
{ int cnt = 0;
int len = strlen(s);
for(int i = 0; i < len; i++)


The highlighted line is the problem. I get this error:

dualstarter.cpp:58: error: initializer fails to determine size of 'params'.

Right now I am thinking of creating an array with the specified size and simply copying the required string into it, but it just seems like there is an easier way.

Programming :: Read Any Given Maze.txt Into An Internal Dynamically Allocated Array Of Strings?

Apr 26, 2011

I am looking for an easy way to convert any given maze.txt of any size to a internal array of strings(dynamically allocated). Important is that dimensions of the maze (row, col) shouldn't be written by the user instead they have to be somehow read from the file. This is not my homework assignment! It is a small part of a project that i never dealt with. I never read files to C string.... I made it for specific maze dimensions, but want it to work with any given .txt file.

Programming :: Save / Load Data Segment Of Dynamically Loaded Shared Object Library?

Aug 25, 2010

Our application uses a dynamically loaded shared object library (codec library) to compress and decompress audio streams.

There happens to be several static and global variables in this shared object library. Hence it is not possible to process two interleaved unrelated media streams using this shared object codec library because each stream corrupts/changes the contents of these static/global variables.

Is there a way through which a context save (save contents of data segment of shared object) and a context load (load previously saved contents of data segment of shared object)operation can be performed on the shared object library. This way the context for each media stream can be saved and loaded before and after processing the "other" media stream respectively.

Hardware :: Flash EEPROM Intel Integrated Ethernet?

May 10, 2010

I have an ethernet card that used to work with Linux, but it had its firmware corrutped. (not as a result of the kernel its a different model) I think it had something to do with the thunderstorm I was using the computer in. Anyway, it is an Intel 82562EZ 10/100 Ethernet Controller (rev 01). The device manager in windows xp calls it an Intel PRO/100 VE card, which I think is the same thing. The card works in windows but not in linux. Upon firing up the intel proset software, and running hardware diagnostics the test says the eeprom test failed. Is there any way I can flash the eeprom so I can have a working card?

EDIT: Card fixed after leaving unplugged. It is important to also unplug the power supply connectors from the motherboard as well as capacitors may not discharge otherwise. Also be sure to remove the cmos battery. Oh, yeah don't try to use that intel utility on integrated networking devices. "IBAUTIL is not intended as a utility for LAN-On-Motherboard (LOM) [integrated] implementations."

Fedora Hardware :: Ultimate-N 6300 Does Not Work Under F13 - Unsupported - Too Old - EEPROM

Nov 11, 2010

I replaced the old WIFI card (Intel PRO 3945ABG) in my Dell D620 with the new Intel Ultimate-N 6300.

According to intel's website the driver is integrated in the current kernel (mine is 61.fc13.i686.PAE) and I have the latest firmware installed as well (iwl6000-firmware- 1.fc13.noarch) however it does not work.

I tested the card with Windows XP and it works perfect.

The output from "dmesg" is:



But with my previous card "lspic -v" will show the driver in use but the new card does not:


So it detect the card for some reason does not assign it a driver!

And i googled this "Unsupported (too old) EEPROM" and found some results related to Ubuntu but were not useful.

So am I missing something? what does that message mean "Unsupported (too old) EEPROM"?

Fedora :: Way To Easily Manipulate Photos And Scans

Jul 17, 2010

I own Fedora Core 12 and an HP scanner. I want to make digital copies of all the pictures I took a few years ago. I have a lot so I tried scanning five at a time thinking I could cut and paste into smaller images like with MS Paint on Windows. HPLIP 3.9.12 wouldn't let me modify the scans so I tried GIMP 2.6.10. GIMP 2.6.10 is a nightmare! When I opened my scan of five pictures I had trouble opening a new image. Then I had to specify the size of the new image. The when I cut and pasted I couldn't rotate. Then when I figured out how to rotate my image was too small.

Then I tried scanning just one picture but HPLIP left a lot of blank space. I tried cropping out the blank space with GIMP but the image size was the same with the blank space. I don't want to post photos to Flickr that are mostly empty space.I wish I could show you examples but the forum won't let me post them.Any ideas or suggestions for a program for Fedora Core 12 that's got the functions and features of MS Paint?
