  • Simple and efficient distribution of C++/Boost source code (amalgamation)

    - by Arrieta
    Hello: My job mostly consists of engineering analysis, but I find myself distributing code more and more frequently among my colleagues. A big pain is that not every user is proficient in the intricacies of compiling source code, and I cannot distribute executables. I've been working with C++ using Boost, and the problem is that I cannot request every sysadmin of every network to install the libraries. Instead, I want to distribute a single source file (or as few as possible) so that the user can g++ source.c -o program. So, the question is: can you pack the Boost libraries with your code, and end up with a single file? I am talking about the Boost libraries which are "headers only" or "templates only". As an inspiration, please look at the distribution of SQlite or the Lemon Parser Generator; the author amalgamates the stuff into a single source file which is trivial to compile. Thank you.

  • Does .NET have a linker?

    - by Water Cooler v2
    From Jon Skeet's blog: What does the following comment mean? // The line below only works when linked rather than // referenced, as otherwise you need a cast. // The compiler treats it as if it both takes and // returns a dynamic value. string value = com.MakeMeDynamic(10); I understand what referencing an assembly is. You may reference it when compiling the program files either using the /ref: switch at the command line or you may add a statically reference to the assembly in Visual Studio. But how do you link to an assembly in .NET? Does he mean, load the assembly using Reflection (Assembly.LoadFile())? Or, the Win32 API LoadLibrary()? Or, does .NET have a linker that I have never heard of?

  • iPhone c++ development / compiler on a non-Mac PC? (Windows? Linux?)

    - by Ehrann Mehdan
    According to the (in)famous iPhone Developer Program License Agreement change 3.3.1 — Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs. Applications must be originally written in Objective-C, C, C++, or JavaScript as executed by the iPhone OS WebKit engine, and only code written in C, C++, and Objective-C may compile and directly link against the Documented APIs (e.g., Applications that link to Documented APIs through an intermediary translation or compatibility layer or tool are prohibited). So it is allowed to develop iPhone apps using C++ My questions Is there a compiler / IDE for developing iPhone apps using C++? Is that compiler / IDE available on non Mac environments? (Windows? Linux?) If not, why? I mean an eclipse C++ plugin for iPhone development will be quite popular, or is there already any serious attempt to do that?

  • Opinions regarding C++ programming practice

    - by Sagar
    I have a program that I am writing, not too big. Apart from the main function, it has about 15 other functions that called for various tasks at various times. The code works just fine all in one file, and as it is right now. However, I was wondering if anyone had any advice on whether it is smarter/more efficient/better programming to put those functions in a separate file different from where main is, or whether it even matters at all. If yes, why? If no, why not? I am not new at C++, but definitely not an expert either, so if you think this question is stupid, feel free to tell me so. Thanks for your time!

  • Calling Stored Procedure from VB.net timeout error

    - by Jim
    When calling a stored procedure from vb.net is there a default SQL timeout time if no timeout is specified in the connection string? I am unsure if there is a CommandTimeout specified in the connection string but am going through all the possibilites. Example if no results after 30 seconds (or more) throw: `System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.` SQL Profiler says that the script runs and ends in 30 seconds when the program timesout.. Tthe script runs without error in about 1 minute 45 seconds by itself in SQL server.

  • Breaking the loop in Jython

    - by kdev
    Hi everyone, I have a written a loop for and if condition and I want to break to loop completely when if gets satisfied. while count: i=0 for line in read_record: #print str.strip(count[1:28]) #print str.strip(read_record[i]) if string.find(str.strip(read_record[i]),str.strip(count[1:28]))>0: code=str.strip(read_record[i+19])+str.strip(read_record[i+20]) print code[25:] break i=i+1 So here if the if string.find condition gets satisfied I want to go to while loop flow. Please tell me what will be the best place to break and how should I modify the program so that once the if condition is satisfied I am out of the loop and start again with while loop.

  • C++ conditional compilation

    - by Shaown
    I have the following code snippet #ifdef DO_LOG #define log(p) record(p) #else #define log(p) #endif void record(char *data){ ..... ..... } Now if I call log("hello world") in my code and DO_LOG isn't defined, will the line be compiled, in other words will it eat up the memory for the string "hello world"? P.S. There are a lot of record calls in the program and it is memory sensitive, so is there any other way to conditionally compile so that it only depends on the #define DO_LOG? Thanks in advance.

  • Deciphering Encoding: Packet Analyzation Tools

    - by Zombies
    I am looking for better tools than wireshark for this. The problem with wireshark is that it does not format the data layer (which is the only part I am looking at) cleanly for me to compare the different packets and attempt to understand the third party encoding (which is closed source). Specifically, what are some good tools for viewing data, and not tcp/udp header information? Particularly, a tool that formats the data for comparison. To be very specific: I would like a program that compares multiple (not just 2) files in hex.

  • Find overdrawn accounts in SQL

    - by mazzzzz
    Hey guys, I have a program that allows me to run queries against a large database. I have two tables that are important right now, Deposits and withdraws. Each contains a history of every user. I need to take each table, add up every deposit and withdraws (per user), then subtract the withdraws from the deposits. I then need to return every user whos result is negative (aka they withdrew more then they deposited). Is this possible in one query? Example: Deposit Table: |ID|UserName|Amount| |1 | Use1 |100.00| |2 | Use1 |50.00 | |3 | Use2 |25.00 | |4 | Use1 | 5.00 | WithDraw Table: |ID|UserName|Amount| |2 | Use2 | 5.00 | |1 | Use1 |100.00| |4 | Use1 | 5.00 | |3 | Use2 |25.00 | So then the result would output: |OverWithdrawers| | Use2 | Is this possible (I sure don't know how to do it)? Thanks for any help, Max

  • Java respawn process

    - by Bart van Heukelom
    I'm making an editor-like program. If the user chooses File-Open in the main window I want to start a new copy of the editor process with the chosen filename as an argument. However, for that I need to know what command was used to start the first process: java -jar myapp.jar blabalsomearguments // --- need this information Open File (fileUrl) exec("java -jar myapp.jar blabalsomearguments fileUrl"); I'm not looking for an in-process solution, I've already implemented that. I'd like to have the benefits that seperate processes bring.

  • what the java command's -jar option really does

    - by JBoy
    Does the -jar option of the java command also compile the sources before running the main method? I believe so but i would like to have a better understanding of the internal process, from the man page you can clearly see a small workflow sequence: -jar Execute a program encapsulated in a JAR file. The first argument is the name of a JAR file instead of a startup class name. In order for this option to work, the manifest of the JAR file must contain a line of the form Main-Class: classname. Here, classname identifies the class having the public static void main(String[] args) method that serves as your application's starting point. See the Jar tool reference page and the Jar trail of the Java Tutorial @ But it does not mention that it compiles the sources.

  • Copying a 2D non-space array to another

    - by Jay
    I'm a total programming newb who started learning java programming this sem at uni. I'm up to a step where i need to copy some elements from one method to another. This program i'm creating is called an L_Game. The question I'm stuck is: the project(Slide other) method should take another slide as a parameter, and copy each non-space cell from this slide into the other slide (i.e. like a projector projecting slides onto a screen. I previously made a constructor with the parameter cells in it and believe i copied it to the project(Slide other) method. But i'm not sure what to do to copy each "non-space cell" With the "for" method or the "if" method? If my question isn't typed correctly or have information missing, please let me know. Any help will be appreciated. (I obviously have no idea with what i'm doing...)

  • python function that returns a function from list of functions

    - by thkang
    I want to make following function: 1)input is a number. 2)functions are indexed, return a function whose index matches given number here's what I came up with: def foo_selector(whatfoo): def foo1(): return def foo2(): return def foo3(): return ... def foo999(): return #something like return foo[whatfoo] the problem is, how can I index the functions (foo#)? I can see functions foo1 to foo999 by dir(). however, dir() returns name of such functions, not the functions themselves. In the example, those foo-functions aren't doing anything. However in my program they perform different tasks and I can't automatically generate them. I write them myself, and have to return them by their name.

  • Self Modifying Code

    - by Betamoo
    I am recently thinking about writing self-modifying programs, I think it may be powerful and fun... So I am currently looking for a language that allow modifying program own code easily.. I read about C# and the ability to compile -and execute- code in runtime, but that is too hurting.. I am also thinking about assembly... it is easier there to change running code but it is not very powerful... Can you suggest me a powerful language -or a feature- that support modifying code in runtime..? Hint: That what I mean by modifying code in runtime Start: a=10,b=20,c=0 label1: c=a+b .... label1= c=a*b goto label1 Thanks

  • Error 500 on template.render() with jinja2

    - by Asperitas
    I am working on playing with some Python to create a webapp. At first I put the HTML in a string, using %s to fill certain elements. That all worked perfectly. Now I want to put the HTML in a template, so I followed this tutorial. My code looks like this (I deleted irrelevant code for this error): import codecs import cgi import os import jinja2 jinja_environment = jinja2.Environment(loader=jinja2.FileSystemLoader(os.path.join(os.path.dirname(__file__)))) class Rot13Handler(webapp2.RequestHandler): def get(self): template = jinja_environment.get_template('rot13.html') self.response.out.write(template.render({'text': ''})) When I replace just template.render({'text': ''}) a random string, the program works fine. I did add the latest jinja2 library to my app.yaml, and naturally my rot13.html does exist with the {{ text }} added. So could anyone please help me in the right direction? I don't know why it's going wrong.

  • How to run AWS sample JAVA code on an EC2

    - by SeaPlusPlus
    I just started with Amazon web services, and I have an EC2 instance. I downloaded the JAVA SDK and the Eclipse toolbox. I am able to run a sample program locally on my PC and connect to the Amazon databases, etc. My question is, what do I need to do to get this working on my EC2 instance? This may not even be specific to AWS. On Eclipse, I can just "Run as Application" and run any code. On the server side, what do I need to do? Should I ftp over my .java files? Should I export it to a jar and upload that? Do I need to install anything special to actually run it? I'm just trying to run the basic DynamoDB example that connects to the database and adds a new table and row

  • Dynamic CCK fields population

    - by boogie
    Hi, How can I create two CCK fields where the latter has values based on the first selection? In my case I have a few programs which can be selected and then projects that are related to programs. I need to have two separate fields for them. Example: Programs: Program1 Program2 Projects: Project1 (related to Program1) Project2 (related to Program2) Project3 (related to Program2) If program "Program1" is selected, then the user should only be able to select "Project1" and in case of "Program2" is selected, the options should be "Project2" or "Project3". I'm using Drupal 6.20 and I've already tried using Conditional Fields and Computed Fields modules, but they don't really solve my problem. Any help is much appreciated!

  • Disambiguating Named Entities in Java

    - by Alterscape
    I have a list of strings (company names, in this case), and a Java program that extracts a list of things that look like company names out of mostly-unstructured text. I need to match each element of extracted text to a string in the list. Caveat: the unstructured text has typos, things like "Blah, Inc." referred to as "Blah," etc. I've tried Levenshtein Edit Distance, but that fails for predictable reasons. Are there known best-practices ways of tackling this problem? Or am I back to manual data-entry?

  • WPF: Reset the positions of scatterviewitems?

    - by sofri
    Hi, I have a scatterview with some items in it which I place with Orientation und Center. Now I want to have the possibility to reset the positions of the scatterviewitems after scaling, rotating and moving them, while the program is running. At the moment I do it this way: private void Reset_ContactTapGesture(object sender, Microsoft.Surface.Presentation.ContactEventArgs e) { item1.Center = new Point(150,150); item1.Orientation = 15; item1.Width = 100; item1.Height = 150; } Is there a better way to do it?

  • Forcing a templated object to construct from a pointer

    I have a fictional class: template<typename T> class demonstration { public: demonstration(){} ... T *m_data; } At some point in the program's execution, I want to set m_data to a big block of allocated memory and construct an object T there. At the moment, I've been using this code: void construct() { *m_data = T(); } Which I've now realised is probably not the best idea... wont work under certain cirumstances, if T has a private assignment operator for example. Is there a normal/better way to do what I'm attempting here?

  • Linux Kernel - Adding field to task_struct

    - by Drex
    I'm playing around with the linux kernel and added a struct field to the task_struct in sched.h. I know that can be costly but my struct is very small. I then initialize the new struct in INIT_TASK() and also re-initialize in fork.c copy_process() function so that when the INIT task or any other task creates a new process the process gets the init values. What then happens is when I try to run the kernel I get a SEGFAULT. The gdb error is: Locating the bottom of the address space ... Program received signal SIGSEGV, Segmentation fault. 0x08066ad7 in page_ok (page=) at arch/um/os-Linux/sys-i386/task_size.c:31 31 n = *address; It looks like it fails out in task_size. Is there anything else I need to do to add a field to task_struct?
