  • Porting a project to OpenGL3

    - by Decapsuleur
    Hi everyone, I'm working on a C++ cross-platform OpenGL application (Windows, Linux and MacOS) and I am wondering if some of you could share some advices on porting a large application to OpenGL 3. The reason I am looking into OpenGL 3 is because I think we could benefit a lot from using the new "Sync objects". Nvidia has supported such an extension since the Geforce 256 days (gl_nv_fences) but there seems to be no equivalent functionality on ATI hardware before OpenGL 3.0+... Our code makes quite heavy use of glut/freeglut, glu functions, OpenGL 2 extensions and CUDA (on supported hardware). The problem I am now facing is that "gl3.h" and "gl.h" are mutually incompatible (as stated in gl3.h). Do you guys know if there is a GL3 glut equivalent ? Also, looking at the CUDA-toolkit header files, it seems that GL-CUDA interoperability is only available when using older versions of OpenGL... (cuda_gl_interop.h includes gl.h...). Am I missing something ? Thanks a lot for your help.

  • Adding libraries to a project in xcode - symbols not found

    - by kudorgyozo
    I am trying to make an iphone app in xcode that uses pjsip. The problem is I don't know how to link the libraries. I have the ARM version of the libraries in this folder in mac os x. /Users/kudorgyozo/pjsip_iphone In Xcode: I have specified the library and header search paths like this: for includes: /Users/kudorgyozo/pjsip_iphone/pjlib/include /Users/kudorgyozo/pjsip_iphone/pjlib-util/include /Users/kudorgyozo/pjsip_iphone/pjmedia/include /Users/kudorgyozo/pjsip_iphone/pjnath/include /Users/kudorgyozo/pjsip_iphone/pjsip/include for libraries: /Users/kudorgyozo/pjsip_iphone/pjlib/lib /Users/kudorgyozo/pjsip_iphone/pjlib-util/lib /Users/kudorgyozo/pjsip_iphone/pjmedia/lib /Users/kudorgyozo/pjsip_iphone/pjnath/lib /Users/kudorgyozo/pjsip_iphone/pjsip/lib and then using the "Other linker flags" : -lpj-arm-apple-darwin9 -lpjlib-util-arm-apple-darwin9 -lpjmedia-arm-apple-darwin9 -lpjmedia-audiodev-arm-apple-darwin9 -lpjmedia-codec-arm-apple-darwin9 -lpjsdp-arm-apple-darwin9 -lpjnath-arm-apple-darwin9 -lpjsip-arm-apple-darwin9 -lpjsip-simple-arm-apple-darwin9 -lpjsip-ua-arm-apple-darwin9 -lpjsua-arm-apple-darwin9 Is this OK like this? Because it gives me symbol(s) not found errors. I think no symbol is found from the "included" libraries. I don't know what is wrong i'm just beginning to understand how building an app works under linux based systems i've only done programming in C# before.

  • Change Visual Studio Default Browser in an ASP.NET MVC project

    - by Kirschstein
    FireFox is set to my Windows default browser. I want to change the default browser used by Visual Studio for debugging. Normally the route I'd take to do this is right clicking on an .aspx file and setting the default from the Browse With... dialog. Unfortunately, ASP.NET MVC Views don't have the Browse With... option. What other ways can you set the default browser for ASP.NET MVC projects? Related, but NOT ASP.NET MVC Specific: Visual Studio opens default browser instead of IE

  • Help to choose NoSQL database for project

    - by potapuff
    There is a table: doc_id(integer)-value(integer) Approximate 100k doc_id and 27?? rows. Majority query on this table - searching documents similar to current document: select 10 documents with maximum of (count common to current document value)/(count ov values in document). Nowadays we use PostgreSQL. Table weight (with index) ~1,5 GB. Average query time ~0.5s. Should I transfer all this to NoSQL base, if so, what?

  • Database hosting options for a PosgreSQL project

    - by AJ
    PostgreSQL has announced an Android app [contest] (http://wiki.postgresql.org/wiki/AndroidAppContest). I wanted to try out something but the only hosting I have does not provide PostgreSQL. Do I have any economical (read cheap :D ) options? Is there a free hosting that anyone knows of? Thanks in advance. --AJ

  • Use same project to create multiple applications on same device

    - by Mark.Prof
    I am deploying a reader application with it's document packaged in the asset folder. Any branding is done by dynamically generating xml and resources as appropriate. The application name itself is also generated. Since it is the tag's "package" property that needs to be unique, I nevertheless have a problem installing more than one instance of this app. I would like to dynamically edit the manifest package attribute's value to reflect the document and brand that I am building. But this causes build problems, specifically the location of R.java is no longer available to the component package under which the code resides. Originally, the component package is the same as the application manifest package. But precisely this manifest package name is the part that needs to be variable. How should I best proceed?

  • How to wrap a thirdparty library COM class for notifications in a C++ project

    - by geocoin
    A thirdparty vendor has provided a COM interface as an external API to their product, and for sending instructions to it, it's fine with the mechanism of generating class wrappers with visual studio by importing from the dll, then creating instances of the created classes, calling their CreateDispatch(), using the access functions and releasing when done. For return notifications, I'd normally create an EventsListener class derived from IDispatch using the Invoke function to handle events returning from the interface. This vendor has created an Events lass which I have to wrap and expose, then explicitly tell the installation where to look. all the example are given is C# where it's really easy, but I'm struggling on how to do it in C++ in the C# example, the interop dll provided is simply added as a reference and derived into a class like so: using System; using System.Runtime.InteropServices; using System.Windows.Forms; using System.Text; using <THIER INTEROP LIB> namespace some.example.namespace { [ComVisible(true)] public class EventViewer : IEvents //where IEvents is their events class { public void OnEvent(EventID EventID, object pData) //overridden function { //event handled here } } } In broad terms I assume that I must create a COM interface, since they require a ProgID from me to instantiate, but how do I derive that's been wrapped by the import and then expose the created class to COM I'm just not sure where to even start, as all the tutorials I've seen so far talk in terms of creating brand new classes not wrapping a third party one

  • Compiling a c++ project using blas (Fortran) in Matlab mex

    - by Yin Zhu
    I am trying to use a package here. I have no problem compiling it under 64-bit Linux as all the Makefiles are already provides. Only minor changes are needed, which I can handle. However, I have a problem compiling it under 64-bit Windows. I have installed gfortran and also compiled BLAS and CBLAS to their static libraries. The problem is that Matlab mex does not support GCC in windows, so I need to use VC 2008 instead. I found in the Makefile this line is to get the final klr_train.mexw64: klr_train.$(MEX_EXT): klr_train.cpp $(MEX) $(MEX_OPTION) klr_train.cpp ../libklr/libklr.cpp $(CBLASDIR)/lib/LINUX/cblas_LINUX.a $(BLASDIR)/blas_LINUX.a -lgfortran I don't know how to execute this line using VC 2008's command line tool cl. As cl obviously does not support -lgfortran, which I think is used to link some library in gfortran to support BLAS.

  • How do I organise my libraries in sub-directories in a web application project

    - by Ravish Bhagdev
    I am working on a huge web-application with hundreds of dependencies (jar files). I want to organise the jars in sensible way as each piece of software comes with its bunch of jar files and when I want to remove or upgrade version of that software it will be easier to do if kept in sub directories. Problem is that when using a web-server (I'm using tomcat), all libs need to be under WEB-INF/lib folder, you cannot create subdirectories otherwise it doesn't load the jars in subdirectories. Thanks.

  • resource-ref at application scope in EJB 2.1 Project

    - by Mike Deck
    Is it possible to define resource references that are applicable to all EJBs in an application? Currently I have an ejb-jar.xml that looks something like this: <ejb-jar> <enterprise-beans> <session id="foo"> <!-- snip --> <resource-ref> <res-ref-name>jdbc/myDatasource</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> </session> <session id="bar"> <!-- snip --> <resource-ref> <res-ref-name>jdbc/myDatasource</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> </session> </enterprise-beans> </ejb-jar> You'll notice that both EJBs have the same resource-ref defined for both of them. Is there a way to factor this duplication out within a J2EE 1.4 application? Ideally I should be able to define the jdbc/myDatasource resource once within the application and have anything running inside that container be able to access it by doing a JNDI lookup for "java:comp/env/jdbc/myDatasource". Is there any way to accomplish this?

  • Creating/Maintaining a large project-agnostic code library

    - by bufferz
    In order to reduce repetition and streamline testing/debugging, I'm trying to find the best way to develop a group of libraries that many projects can utilize. I'd like to keep individual executable relatively small, and have shared libraries for math, database, collections, graphics, etc. that were previously scattered among several projects and in many cases duplicated (bad!). This library is to be in an SVN repo and several programmers will be working on it. This library will be in constant development along with the executables that utilize it. For example, I want a code file in ProjectA to look something like the following: using MyCompany.Math.2D; //static 2D math methods using MyCompany.Math.3D; //static #D math methods using MyCompany.Comms.SQL; //static methods for doing simple SQLDB I/O using MyCompany.Graphics.BitmapOperations; //static methods that play with bitmaps So in my ProjectA solution file in VisualStudio, in order to develop/debug the MyCompany library I have to add several projects (Math, Comms, Graphics). Things get pretty cluttered and Solution files get out of date quickly between programmer SVN commits. I'm just looking for a high level approach to maintaining a large, shared code base in an SCN repository. I am fully willing to radically redesign my approach. I'm looking for that warm fuzzy feeling you get when you're design approach is spot on and development is fluid and natural. And ideas? Thanks!!

  • project organization between x86 and x64

    - by Steve
    I have a mixed language solution in VS2008. I would like to structure the bin such that I have bin\x86\Release and bin\x64\Release among the other options. I can do something like this if I have all C# or all C++, but as the platform names don't overlap (x86 vs. Win32) between C++ and C#, I can't seem to do this with the macros (and have an easy solution). I've tried to add a new platform and it won't let me. Is there an easy way to do this?

  • Looking for *small*, open source, c# project with extensive Unit Testing

    - by Gern Blandston
    (I asked this question but did not receive much response. It was recommended that I ask the same question with regards to C#. ) I am a VB.NET developer with little C# experience (yes, I know I need to write more in C#), looking for small open source projects that demonstrate high unit testing coverage from which to learn. I'm looking for small projects because I don't want to have to wade through a ton of code to get a better understanding of how to apply unit testing in my own situation, in which I write mostly IT business apps used internally by my company. UPDATE: Original question that got me asking about this is here

  • VS2010 always relinks the project

    - by Rob Walker
    I am migrating a complex mixed C++/.NET solution from VS2008 to VS2010. The upgraded solution works in VS2010, but the build system is always refereshing one C++/CLI assembly. It doesn't recompile anything, but the linker touches the file. The causes a ripple effect downstream in the build as a whole bunch of dependent then get rebuilt. Any ideas on how to find out why it thinks it needs to relink the file? I've turned on verbose build logging, but nothing stands out.
