In my project,Login window is created as a Dialog box.So when i tried to call the constructor of Login from Main it was generating an error regarding the arguments passed.I have not used any arguments when i called. when i looked at the code, the function was declared as public Login(java.awt.Frame parent,boolean modal)so when i call it from main(),what am i supposed to do ?
View 3 RepliesHow does a C program start in linux? Is main() the first function called in the a c application by kernel. I understand it is the first called function written by the application programmer, but the question is to understand the what all kernel does and what all functions it calls before calling main()

When we are externally overloading the copy constructor is there any optimization strategies when we are using several copy constructors.
My setup is Ubuntu 10.04, eclipse 3.5.2 I have created the source for a shared object and a test program to test it. The program executes dlopen() and I get back a valid library handle. I can use that handle and dlsym() to get the address of my C exported functions just as I expect. I recently added a change to have the so instantiate an object at load time by using a __attribute__ ((constructor)) function named so_init(). I also added a main() function (one wasn't required before). Adding a bunch of printf()s and using the debugger in eclipse I watch the code run and the so_init() and main() functions are never called. As far as I can tell, eclipse has -shared, -fPIC and -Wl setup and specified correctly. Am I missing a compile/link flag? Is there some magic I need in the so_main.cpp to get this working. I have this written as dual source code. The same code works quite nicely in Windows which calls dllMain() as expected.

View 5 Replies View RelatedI recently upgraded from Ubuntu 10.04 to 10.10. All was going well until netbeans started throwing up errors about not being able to find the "stddef.h" header being called from the stdio and stdlib headers. Now I am unable to even initialize variables without failing.
I was using 6.9.1 from the netbeans website, but then I installed 6.9 from the repos alongside, and I still get the same error. Do I need to remove 6.9.1 ( I would rather remove it and keep the repo version), and if so, how do I do it?
where the stddef.h file is located so that I can replace it, or know of any work around?

View 3 Replies View RelatedI have found a weird behaviour on a linux application. A tty seems to get closed without calling close. The program is (very simplified) as follows:
Process 1:
configure_signals()
read_config_files()
create_threads()
wait(forever)
Thread 1:
fd=open(/dev/ttyXX)
usleep(a while)
config(fd)
I have spent quite a lot of time on this problem. It seems like the file is sometimes closed when reaching config(fd), but removing the usleep(a while) seems to remove the problem.

I'm trying to call a system command in perl and am having an issue with it.
Here's an example of a command i'd like to call: Code: sed -i '4 c192.168.1.4 www.something.com' hosts this is the section in my perl script where I create the variable and call it: Code: $doit = `sed -i '$line c$ip $host hosts'`system($doit); The $line, $ip, and $host variables are working fine becasue I can replace that section with "prints" and they come out fine. I imagine the problem is where I am creating the $doit variable.

I feel like there should be a cleaner way of doing this. I have one file, for example "a.cpp", calling a function from another file, "b.cpp". Currently I have it set up so that header for "b", "b.h", has the declaration of its functions. And then I'm just including "b.h" in "a.cpp". Do I have to include the "b" header file in "a" to be able to call a function from "b"? Or is there a better way I could be doing this? Like doing something different at compile?

I'm trying to call some kernel functions from userspace, but I'm not sure if I'm doing it right. The functions control a pulse width modulator on an embedded platform. To pick one at random, the function:
Code:
struct pwm_device *pwm_request(int pwm_id, const char *label);
is defined in linux/pwm.h, and the implementation uses the macro EXPORT_SYMBOL(pwm_request), so I should be able to call this from user-space... right?
Anyway, I've got linux/pwm.h to #include in my source so the compiler knows what it's doing, but what do I link against? The only place in by kernel build tree where I can see a symbol pwm_request defined is in object files like vmlinux.o, built-in.o in the directory, etc. which I don't think I should be linking against.
I have written FORTRAN code to calculate density profile. This code will open two files ( topology and x,y,z trajectory). The trajectory file contains XYZ data coordinates for multiple frames (about 20 or 100 frames for instance). One frame contains 20736 data.
Previously this code was written to open ONLY one input XYZ data file and do the calculation and would dump the results in separate file and it was running without problem. Recently my data file get bigger in size, so I decided to break the single XYZ data file into few small parts.
Now I have modified the code so that it calls the parts of the XYZ data files ( eg: maltoTHERMO_10Frames.traj, maltoTHERMO_20Frames.traj,... and so on) and do the calculation and dump the results in the same result output file. I have tested this code just with openning the XYZ coordinates and printing into another file to see wheather it collecting the data sequently and it was working fine.
This code supposedly read the x coordinate data and calculate distance and put a count accoding the criteria in the approperiate bins. But when I let the code to do the calculation it stop and shows error. (I have indicated as !** in the code). If I enable this line, it shows error but if I disable this line, than the code do collect only the XYZ coordinates.
The code is as below:
Code:
module all_parameter
integer,parameter :: MAXATOM=20736!CHANGE
integer,parameter :: midwater=1500
