问题 I've install a program in Centos 6.8, While running the program, I receive error "error while loading shared libraries: libm.so.6: cannot open shared object file: No such file or directory" when I checked the linked library to the program using ldd command, I can see libm.so.6 with correct 64bit "libm.so.6 => /lib64/libm.so.6 (0x0000003a19000000)" That means, library is installed and already added in environment variable, LD_LIBRARY_PATH Another program, which uses libm.so.6, works fine. Can

问题 In Objective-C there is the Alloc/Init metaphor. They've also added a shared convenience method called 'new' that internally just calls both in succession. And if I create a subclass of NSObject called FooClass, FooClass picks up those shared methods, including 'new'. BUT... how the heck is that implemented?? It can't simply delegate to the base class because that would just instantiate an instance of NSObject, not your derived class FooClass, yet it still works! So how would someone write

问题 Please help to write c++ allocator for std::vector< nIcon*> class. All examples i find shows just what methods i need to overwrite, not code examples. I need to implement allocator using shared memory on windows (using CreateFileMapping and MapViewOfFile) 回答1: May I suggest you look at the boost interprocess library? It allows you to create allocators using shared memory. I've seen some examples around, I would say just look a bit more. I agree that none of them do a perfect job, thus I won't

问题 I am pretty a beginner in C++. I have following problem. In the class MevisPatientModel I defined: typedef boost::shared_ptr<egMevisPatientModel> Ptr_t; Then I "defined" the variable: egMevisPatientModel::Ptr_t v_PatientModel; Now when I try to access the getType function of the class MevisPatientModel : v_PatientModel->getType() ...I'm getting following message: Assertion failed! ...shared_ptr.hpp Expression px!= 0 My intention is that the pointer wasn't initialized. Now I know that here are

问题 I wonder why Visual Studio is raising this warning: Access of shared member, constant member, enum member or nested type through an instance My code: Dim a As ApplicationDeployment = deployment.Application.ApplicationDeployment.CurrentDeployment If System.Deployment.Application.ApplicationDeployment.IsNetworkDeployed Then If a.IsNetworkDeployed Then ' do something End If End If What implies "through an instance"? Also, why is this a "warning"? 回答1: Showing a warning is a design option. In C#,

问题 Using Python and openpyxl I have a code that goes into a workbook, adds a bunch of information to some cells every day, and then closes and saves it. My problem is that if this workbook is open the code doesn't work (obviously). By making the workbook shared(multiple users can edit at once) I can overcome this problem, however after the code runs once, python saves and then reverts it back to a closed, unshared workbook. Anyone know if openpyxl can save as shared? I'm not finding anything

问题 I have very limited access to enable extensions etc on my hosting but am looking to generate a PDF from an HTML page (with css/images) through PHP. Any ideas how I can achieve this with next to zero CL access etc? Preferable not a "hack" / relient on a service (as I'll be looking to use this long term). 回答1: When generating HTML to render in to the PDF, create that HTML in single $html variable. This can be used to pass to the any of the pdf rendering api's. Widely used API's are DOM PDF,

问题 All my apps have the same sharedUserId. I would like to start a class of another app using the class of my current app. I want to use intent extras but I do not want to use intent URLs. I also would prefer not to have to change the AndroidManifest of my target activity's app. 回答1: Its pretty easy since you have the sharedUserId set. Intent res = new Intent(); String mPackage = "com.your.package"; String mClass = ".actYouAreLaunching"; res.setComponent(new ComponentName(mPackage,mPackage
