问题 I am trying to experiment with the inline library. I tried the first example given at http://adv-r.had.co.nz/C-interface.html library(inline) add <- cfunction(signature(a = "integer", b = "integer"), " SEXP result; PROTECT(result = allocVector(REALSXP, 1)); REAL(result)[0] = asReal(a) + asReal(b); UNPROTECT(1); return(result); ") I get the following error: Warning message: running command 'make -f "C:/PROGRA~1/R/R-30~1.3/etc/x64/Makeconf" -f "C:/PROGRA~1/R/R-30~1.3/share/make/winshlib.mk"

问题 I want to give a friend of mine a release build of a little project. It works perfectly fine when started from inside qtcreator, but doesn't open when double-clicked on the .exe file. It doesn't even give me an error message. Now when I tried to copy a few Qt .dll files (like Qt5Core.dll, Qt5Gui.dll, Qt5Widgets.dll) next to my exe file, it didn't change anything. How can I know what dependencies my project has? The .pro file doesn't tell me so much QT += core gui greaterThan(QT_MAJOR_VERSION,

问题 I observe a strange behavior of wildcard expansion behavior for Java7 on Windows. For centuries there was a clean difference between "*" versus *. Seems this it not longer true for Java7 (at least on Windows7). I noticed the problem when using a wildcard classpath. In despite of quoting the wildcard-classpath it gets expanded. Thus it seems not possible any more to pass a wildcard to the java application. So using java -cp "somewhere/*" will fail (as does "somewhere\*" ). A workaround seems

问题 How can my C# code run git commands when it detects changes in tracked file? I am writing a VisualStudio/C# console project for this purpose. I am new to the the .NET environment and currently working on integrating automated GIT commits to a folder. I need to automatically commit any change/add/delete on a known folder and push that to a git remote. Any guidance appreciated. Thank you. Here is what I have and the last one is the one I need some guidance with: Git repository initially set up

问题 I'm encountering an odd issue on a sampling profiler in Windows 7 (no such issues AFAICT on previous Windows OSes, be they 32 or 64 bit). The profiler works by periodically suspending a thread with SuspendThread, then looks at the context with GetThreadContext, before invoking ResumeThread to restart the process. All this is done from the context of the thread of a multimedia timer (for accuracy, at about 1kHZ, which on pre-Windows 7 OSes usually incurs a negligible performance penalty).

问题 I'm using Windows 7 and running XAMPP MySQL SVC service. I'm seeing the following error: Windows could not start the Mysql service on Local Computer. Error 1067: The process terminated unexpectedly. What does this mean, and how can I fix it? 回答1: Examine error log (start eventvwr.msc). MySQL typically writes something to the Application log. In very rare cases it does not write anything (I'm only aware of one particular bug http://bugs.mysql.com/bug.php?id=56821, where services did not work

问题 i have some problems installing Laravel 4.1 in Windows 7 via the first method explained in the Laravel documentation ( http://laravel.com/docs/installation#install-laravel ). So I downloaded the laravel.phar file and put it in my path ( System32 ). Which would be the equivalent of /usr/bin in linux based systems? ( I also added .PHAR in the PATHEXT system variable ). When i ran the laravel command from the command line it didn't know how to open it, so i chose to open it with php.exe. Now,
