  • Compiling program that uses libpcap on Mac OSX using iPhone 3.1.1 SDK for use on iPhone

    - by Alan
    Hey SOV users, I have a question that I'm hoping some iPhone Developers may be able to help with. I had a look at statically compiling a binary on my Mac and moving it over to the iPhone for execution. I have managed to get this bit of it working by installing the iPhone 3.1.3 SDK on my Mac and setting the architecture to the iPhone in the gcc line as follows; /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc -I ~/Downloads/libpcap-1.1.1/pcap-compiled/ -arch armv6 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.1.sdk -o test test.c I have managed to successfully compile a "Hello World" C program and executed it on the iPhone with success. e.g. include int main() { printf("Hello, World!\n"); return(0); } This worked a charm. I am also using 'ldid' to sign the application (but only if necessary). Anyways, I have been trying to get a program to compile which uses libpcap (http://www.tcpdump.org/) but with little success. I have downloaded and installed libpcap-1.1.1 on my mac and set the configure --prefix to /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.1.sdk/usr/local and build the application. I then saw that the includes actually reside in Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.1.sdk/usr/includes and so moved the Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.1.sdk/usr/local/include files (which contained only the pcap stuff) to the correct location. I then attempted to compile the test program using; /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc -I /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.3.sdk/usr/include/ -arch armv6 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.1.sdk -o pcap pcap.c -lpcap This worked a lot better than other tests but produces an error; i.e. ld: library not found for -lcrt1.o collect2: ld returned 1 exit status Do you have any ideas as to how I can do this successfully? I've tried a load of different things but none seem to be successful. Basically, I just want to install (or add) some headers to the existing iPhoneOS SDK for use in compiling programs. Any ideas? Cheers, A

  • about buffer overflow

    - by Abed
    hello guys, I am new to the ethical hacking world, and one of the most important things is the stack overflow, anyway I coded a vulnerable C program which has a char name [400] statement, and when I try to run the program with 401A's it doesn't overflow, but the book which I am following says it must overflow and the logic sense says so, so what's wrong???

  • Embed custom font in Actionscript 3 project

    - by Jan
    I want to display "Hello World" with calibri.ttf using only AC3. How would I do that? Found two solutions on the web but I cannot use any of them - The Adobe documentation site requires the use of Flash CS4. (Don't know how to use this in Flex Builder) - The embed tag method requires FLEX SDK Is it possible to embed font with purely Actionscript 3 in an actionscript project using Flex Builder?

  • WPF Debugging AvalonEdit binding to Document property.

    - by kubal5003
    Hello, all day long I am sitting and trying to find out why binding to AvalonEdits Document property isn't working. AvalonEdit is an advanced WPF text editor - part of the SharpDevelop project.(it's going to be used in SharpDevelop v4 Mirador). So when I set up a simple project - one TextEditor (that's the AvalonEdits real name in the library) and made a simple class that has one property - Document and it returns a dummy object with some static text the binding is working perfectly. However in real life solution I'm binding a collection of SomeEditor objects to TabControl. TabControl has DataTemplate for SomeEditor and there's the TextEditor object. <TabControl Grid.Column="1" x:Name="tabControlFiles" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" > <TabControl.Resources> <DataTemplate DataType="{x:Type m:SomeEditor}"> <a:TextEditor Document="{Binding Path=Document, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, Converter={StaticResource NoopConverter}, IsAsync=True}" x:Name="avalonEdit"></a:TextEditor> </DataTemplate> </TabControl.Resources> <TabControl.ItemContainerStyle> <Style BasedOn="{StaticResource TabItemStyle}" TargetType="{x:Type TabItem}"> <Setter Property="IsSelected" Value="{Binding IsSelected}"></Setter> </Style> </TabControl.ItemContainerStyle> </TabControl> This doesn't work. What I've investigated so far: DataContext of TextEditor is set to the proper instance of SomeEditor TextEditors Document property is set to some other instance than SomeEditor.Document property when I set breakpoint to no-op converter that is attached to that binding it shows me the correct value for Document (the converter is used!) I also dug through the VisualTree to obtain reference to TextEditor and called GetBindingExpression(TextEditor.DocumentProperty) and this did return nothing WPF produces the following information: System.Windows.Data Information: 10 : Cannot retrieve value using the binding and no valid fallback value exists; using default instead. BindingExpression:Path=Document; DataItem='SomeEditor' (HashCode=26280264); target element is 'TextEditor' (Name='avalonEdit'); target property is 'Document' (type 'TextDocument') SomeEditor instance that is bound to already has a created and cached copy of Document before the binding occurs. The getter is never called. Anyone can tell me what might be wrong? Why BindingExpression isn't set ? Why property getter is never called?

    Trying to convert const wchar_t * to NSString. The following code only produces the first character. I've tried the different CFAllocator options as well but with no success. Can anyone help me or point to how I can convert wchar_t * to NSString const wchar_t *data = L"Hello World"; int l = wcslen(data); CFStringRef c = CFStringCreateWithCharacters(kCFAllocatorSystemDefault, (const UniChar *) data,l); NSString *nStr = (NSString *)c; //This always gives me 'H'

    - by Ali Nadalizadeh
    I'm working on an OpenGL ES1 app which displays a 2D grid and allows user to navigate and scale/rotate it. I need to know the exact translation of View Touch coordinates into my opengl world and grid cell. Are there any helpers to do the reverse of last few transforms which I do for navigation ? or I should calculate and do the matrix stuff by hand ?

  • Java HashSet key/value pair

    - by harley
    Why does Java not provide functions to get at the key/value pairs in a HashSet like in Hashtable? It seems like a real pain to have to iterate over it every time you need to get at something. Or am I just a newb missing something?

  • Alternative to System.Web.HttpUtility.HtmlEncode/Decode?

    - by Jörg Battermann
    Is there any 'slimmer' alternative to the System.Web.HttpUtility.HtmlEncode/.Decode functions in .net 3.5 (sp1)? A separate library is fine.. or even 'wanted', at least something that does not pull in a 'whole new world' of dependencies that System.Web requires. I only want to convert a normal string into its xml/xhtml compliant equivalent (& back).

I use floyd to find the shortest path and I'll draw the path in the image ( by coordinates I think ) . This is the first time I write a real program in C# so how should I implement this one ;) Thanks so much for reading !

    Are there any generally-accepted coding standards (naming, casting etc) that apply specifically to iPhone/Cocoa/Objective-C? I know Microsoft has published similar standards as they relate to .Net and C# but haven't run across anything related to the iPhone world.

  • Stop lazy loading or skip loading a property in NHibernate? Proxy cannot be serialized through WCF

    - by HelloSam
    Consider I have a parent, child relationship class and mapping. I am using NHibernate to read the object from the database, and intended to use WCF to send the object across the wire. Goal For reading the parent object, I want to selectively, at different execution path, decide when I would want to load the child object. Because I don't want to read more than what I needed. Those partially loaded object must be able to sent through WCF. When I mean I don't load it, neither side will access such property. Problem When such partially loaded object is being sent through WCF, as those property is marked as [DataContract], it cannot be serialized as the property is lazy load proxy instead of real known type. What I want to archive, or solution that I can think of lazy=false or lazy=true doesn't work. Former will eagerly fetch all the relationships, latter will create a proxy. But I want nothing instead - a null would be the best. I don't need lazy load. I hope to get a null for those references that I don't want to fetch. A null, but not just a proxy. This will makes WCF happy, and waste less time to have a lazy-load proxy constructed. Like could I have a null proxy factory? -OR- Or making WCF ignoring those property that's a proxy instead of real. I tried the IDataContractSurrogate solution, but only parent is passed to GetObjectToSerialize, I never observe an proxy being passed through GetObjectToSerialize, leaving no chance to un-proxy it. Edit After reading the comments, more surfing on the Internet... It seems to me that DTO would shift major part of the computation to the server side. But for the project I am working on, 50% of time the client is "smarter" than the server and the server is more like a data store with validation and verification. Though I agree the server is not exactly dumb - I have to decide when to fetch the extra references already, and DTO will make this very explicit. Maybe I should just take the pain. I didn't know http://automapper.codeplex.com/ before, this motivates me a little more to take the pain. On the other hand, I found http://trentacular.com/2009/08/how-to-use-nhibernate-lazy-initializing-proxies-with-web-services-or-wcf/, which seems to be working with IDataContractSurrogate.GetObjectToSerialize.

  • Trimming GIT Checkins

    - by yar
    I check my code into a GIT branch every few minutes or so, and the comments end up being things like "Everything broken starting again" and other absurdities. Then every few minutes/hours/days I do a serious checkin with a real comment like, "Fixed bug #22.55, 3rd time." How can I separate these two concepts? I would like to be able to remove all my frequent-checkins and just leave the serious ones.

    I think that this question already questioned, and probably the answer is here: http://wiki.developers.facebook.com/index.php/Notifications.send but the real problem is that facebook says: Facebook discontinued support for this method March 1, 2010. Calling this method returns error code 3 -- Unknown method. while, I couldn't find any other JS-api for the invitation, anyone know how we can invite users, using the JS api or the .net api? thanks.

    I'm trying to load up the estimated world population from http://www.census.gov/ipc/www/popclockworld.html using AJAX, and so far, failing miserably. There's a DIV with the ID "worldnumber" on that page which contains the estimated population, so that's the only text I want to grab from the page. Here's what I've tried: $(document).ready(function(){ $("#population").load('http://www.census.gov/ipc/www/popclockworld.html #worldnumber *'); });

    Hi I've been trying out NDepend, been reading a few blogposts about it and even heard a podcast. I think that NDepend might be a really useful tool, but I still don't see where I would use it. How do you use it? Do you use it, why? why not? I would like to hear about some down to earth real world examples.
