  • Moving directory after compilation of R

    - by CravingSpirit
    I compiled R in /tmp/R-3.0.0 and then moved it to /home/user/opt/R-3.0.0, then I got an error when executing R: /home/kaiyin/opt/R-3.0.0/bin/R: line 236: /tmp/R-3.0.0/etc/ldpaths: No such file or directory ERROR: R_HOME ('/tmp/R-3.0.0') not found If I export R_HOME='/home/kaiyin/opt/R-3.0.0', it still gives almost the same error: WARNING: ignoring environment value of R_HOME /home/kaiyin/opt/R-3.0.0/bin/R: line 236: /tmp/R-3.0.0/etc/ldpaths: No such file or directory ERROR: R_HOME ('/tmp/R-3.0.0') not found Is there a way to solve this, or do I have to recompile it?

  • c++ compilation error

    - by clamp
    hello, i got a compile error which i do not understand. i have a h/cpp file combination that does not contain a class but just defines some utility functions. when i try to use a struct that is defined in another class i get the error: error C2027: use of undefined type so, stripped down to the problem, the h file looks like this namespace A { void foo(B::C::SStruct const & Var); } the definition of SStruct is in a class which is in another h-file, that is of course included. namespace B { Class C { struct SStruct { }; } } what am i missing here? thanks!

  • Hudson.. another Continuous Integration tool

    - by Narendra Tiwari
    In my previous posts I discussed about Cruisecontrol.net and its legacy support to .Net development. Hudson  is yet another continuous integration tool. Hudson is also free like CCNet and built in java. - CCNet has its legacy support to .Net applications where as Hudson can be easily configured on both the environments (.Net and Java). - One of the major differences in CCNet and Hudson is the richer GUI of Hudson provide user interactive screens for project configuration where as in CCNet we have to play with a few xml configuration files. Both the tools are capable of providing basic features of continuous integration e.g.:- - Source Control configuration - Code Compilation/Build - Ad hoc plugin tools to be configured along with compilation Support for adhoc tools seems to be bigger with CCNet e.g. There are almost every source control plugin available with CCNet where as Hudson has support for limited source control servers. Basically there is an interseting point to see is that there are 2 major partsof whole CI system one performed by build tool and rest. Build tool takes care of all adhoc plugin tools  so no matter if CI tool does not have plugin for that tool if thet tools provides command line support that can be configured in build tool and that build tool is then configured with CI tool inturn. For example if I have a build script configured in MSBuild and CCNet can be easily switched to Hudson. Here we need not to change anything in build script we just need to configure MSBuild on Hudson and pass the path of script file and thats it... all is same.

  • VS 11 Beta merge tool is awesome, except for resovling conflicts

    - by deadlydog
    If you've downloaded the new VS 11 Beta and done any merging, then you've probably seen the new diff and merge tools built into VS 11.  They are awesome, and by far a vast improvement over the ones included in VS 2010.  There is one problem with the merge tool though, and in my opinion it is huge.Basically the problem with the new VS 11 Beta merge tool is that when you are resolving conflicts after performing a merge, you cannot tell what changes were made in each file where the code is conflicting.  Was the conflicting code added, deleted, or modified in the source and target branches?  I don't know (without explicitly opening up the history of both the source and target files), and the merge tool doesn't tell me.  In my opinion this is a huge fail on the part of the designers/developers of the merge tool, as it actually forces me to either spend an extra minute for every conflict to view the source and target file history, or to go back to use the merge tool in VS 2010 to properly assess which changes I should take.I submitted this as a bug to Microsoft, but they say that this is intentional by design. WHAT?! So they purposely crippled their tool in order to make it pretty and keep the look consistent with the new diff tool?  That's like purposely putting a little hole in the bottom of your cup for design reasons to make it look cool.  Sure, the cup looks cool, but I'm not going to use it if it leaks all over the place and doesn't do the job that it is intended for. Bah! but I digress.Because this bug is apparently a feature, they asked me to open up a "feature request" to have the problem fixed. Please go vote up both my bug submission and the feature request so that this tool will actually be useful by the time the final VS 11 product is released.

  • What is the best aproach for coding in a slow compilation environment

    - by Andrew
    I used to coding in C# in a TDD style - write/or change a small chunk of code, re-compile in 10 seconds the whole solution, re-run the tests and again. Easy... That development methodology worked very well for me for a few years, until a last year when I had to go back to C++ coding and it really feels that my productivity has dramatically decreased since. The C++ as a language is not a problem - I had quite a lot fo C++ dev experience... but in the past. My productivity is still OK for a small projects, but it gets worse when with the increase of the project size and once compilation time hits 10+ minutes it gets really bad. And if I find the error I have to start compilation again, etc. That is just purely frustrating. Thus I concluded that in a small chunks (as before) is not acceptable - any recommendations how can I get myself into the old gone habit of coding for an hour or so, when reviewing the code manually (without relying on a fast C# compiler), and only recompiling/re-running unit tests once in a couple of hours. With a C# and TDD it was very easy to write a code in a evolutionary way - after a dozen of iterations whatever crap I started with was ending up in a good code, but it just does not work for me anymore (in a slow compilation environment). Would really appreciate your inputs and recos. p.s. not sure how to tag the question - anyone is welcome to re-tag the question appropriately. Cheers.

  • Low-level GPU code and Shader Compilation

    - by ktodisco
    Bear with me, because I will raise several questions at once. I still feel, though, that overall this can be treated as one question that may be answered succinctly. I recently dove into solidifying my understanding of the assembly language, low-level memory operations, CPU structure, and program optimizations. This also sparked my interest in how higher-level shading languages, GLSL and HLSL in particular, are compiled and optimized, as well as what formats they are reduced to before machine code is generated (assuming they are not converted directly into machine code). After a bit of research into this, the best resource I've found is this presentation from ATI about the compilation of and optimizations for HLSL. I also found sample ARB assembly code. This sort of addressed my original curiosity, but it raised several other questions. The assembler code in the ATI presentation seems like it contains instructions specifically targeted for the GPU, but is this merely a hypothetical example created for the purpose of conceptual understanding, or is this code really generated during shader compilation? If so, is it possible to inspect it, or even write it in place of the higher-level syntax? My initial searches for an answer to the last question tell me that this may be disallowed, but I have not dug too deep yet. Also, along the same lines, are GLSL shader programs compiled into ARB assembly code before machine code is generated, and is it possible to write direct ARB assembly? Lastly, and perhaps what I am most interested in finding out: are there comprehensive resources on shader compilation and low-level GPU code? I have been unable to find any thus far. I ask simply because I am curious :)

  • Classes as a compilation unit

    - by Yannbane
    If "compilation unit" is unclear, please refer to this. However, what I mean by it will be clear from the context. Edit: my language allows for multiple inheritance, unlike Java. I've started designing+developing my own programming language for educational, recreational, and potentially useful purposes. At first, I've decided to base it off Java. This implied that I would have all the code be written inside classes, and that code compiles to classes, which are loaded by the VM. However, I've excluded features such as interfaces and abstract classes, because I found no need for them. They seemed to be enforcing a paradigm, and I'd like my language not to do that. I wanted to keep the classes as the compilation unit though, because it seemed convenient to implement, familiar, and I just liked the idea. Then I noticed that I'm basically left with a glorified module system, where classes could be used either as "namespaces", providing constants and functions using the static directive, or as templates for objects that need to be instantiated ("actual" purpose of classes in other languages). Now I'm left wondering: what are the benefits of having classes as compilation units? (Also, any general commentary on my design would be much appreciated.)

  • command line tool text output

    - by Martin
    I have a small command line tool and after running it, I'd like to display the text output in a way that's easy for someone to copy/paste and save it or email it to someone else. Copy/pasting from a command prompt is not done in the standard way, so I don't want people to have to copy/paste from there. Saving the file to disk is possible, but the folder where the tool is located may not have access rights so the user would have to configure the output file location (this may be too tricky for some users). I was thinking of launching notepad with some text in it, generated from the command line tool. Is this possible? Any other suggestions?

  • XCode iPhone OS Deployment Target Tool

    - by Trah Divad
    Problem I'm currently stuck trying to figure out what "iPhone OS Deployment Target" setting to use. I do not want to write conditional code right now, so I'd like the lowest version that runs my application fine. At first I thought it would be 2.0 as I wasn't using any 3.0 features, but then i realized that AVAudioRecorder is a 3.0 API. I don't want to be manually checking EVERY function I use in the documentation. Question Is there a tool that will check the OS availability of each functions you call in your code to figure out what the Deployment Target should be? That tool could be a good old compiler, but the latest version of the iPhone SDK does not come with the PRE-3.0 SDKs.

  • A testing feedback/report tool?

    - by Mert
    I'm thinking of developing a pluggable test and assessment module. This tool will be used especially for desktop application projects to report and log errors, bugs, missing features and suggestions from testers. The tool will be plugged to the application by putting a small icon to the application itself. When pressed the tool will be visible where user can create entries about the application. Is there already a tool like that? I am not speaking about UI testing btw. For example, this tool might have a form consisting of Page name Environment information Entry type (can be bug, feature request, suggestion) Message User Info (name, contact etc) Date I think such a tool can greatly help testers prepare reports. Developers can understand the issue better and track all the reports.

  • Http Request Monitoring Tool

    - by noli
    Hi! I would like to know if anybody can recommend an Http Request Monitoring Tool aside from HttpWatch and Firebug. What I want from the tool is for it to show me the time it took the request to arrive at the web server. HttpWatch can show me the network latency and the server times in one result but i want them separately. My goal is to isolate the network latency from the server processing times. Thanks.

  • OpenGl ES Eraser Tool

    - by Erika
    Hi Everyone, I am trying to implement an OpenGL eraser tool. I am struggling with this. I was thinking of painting somehow over the previous changes to "clear" out the changes. I can't use the background color because it is not a pattern, not one solid color. Can you point me to the right direction on how to implement an eraser tool ? This is for the iPhone OS but that shouldn't matter. Thanks

  • Kernel module compilation fails when installing vmware tools

    - by nekooee
    When I install WMWare tools, I get this error for vmhgfs: /tmp/vmware-root/modules/vmhgfs-only/filesystem.c:47:28: fatal error: linux/smp_lock.h: No such file or directory compilation terminated. compilation terminated. make[2]: *** [/tmp/vmware-root/modules/vmhgfs-only/filesystem.o] Error 1 make[1]: *** [_module_/tmp/vmware-root/modules/vmhgfs-only] Error 2 make[1]: Leaving directory `/usr/src/linux-headers-3.0.0-12-generic' make: *** [vmhgfs.ko] Error 2 make: Leaving directory `/tmp/vmware-root/modules/vmhgfs-only' If you wish to have the shared folders feature, you can install the driver by running vmware-config-tools.pl again after making sure that gcc, binutils, make and the kernel sources for your running kernel are installed on your machine. These packages are available on your distribution's installation CD. And /mnt/hgfs is empty when sharing. If I run vmware-hgfsclient in a terminal, I get the list of shared folders but /mnt/hgfs is empty.

  • Tales from the Coal Face - Speeding up a C# compilation

    - by TATWORTH
    At one place, I was faced with a C# solution which when XML documentation was turned on, the compilation time increased from 45 seconds to over 8 minutes. This slowdown was unacceptable, however some digging revealed an excellent suggestion by Eric Woodruff at http://social.msdn.microsoft.com/Forums/en-US/devdocs/thread/9bbad4cc-e229-49da-a6f7-3cdf470ac53a/ where he suggested "just suppress the warning by entering it's number (1591 for C#) in the Suppress Warnings field on the Build tab of the project properties". I followed Eric's suggestion and the compilation time went back down to 45 seconds. Now that CS1591 is suppressed how was missing documentation to be found? All that was necessary was to run StyleCop!

  • Software Engineering Component Repository Tool

    - by user320480
    Hello, I'm working as a software engineer for a company. We are going to apply some software engineering standards in our development process. We need a tool which provides a repository for our peripheral products (functions, classes, libraries, ...) which is created during software development process for later use. The tool should provide some functionalities (e.g Name of the component, it's functionality, withing which projects it is used?, author, publication date, list of known bugs, user rating, comment, ...) and it's better to have a web-based interface. Does anybody know such a software?
