preprocessor

问题 I am fairly new to use Fortran preprocessing statement and have a question which is probably pretty native. Can Fortran preprocessing statement be indented? I tested using Gfortran 4.8.1 on Linux (openSUSE Leap) and it turned out I it can not be indented at all. The following code main.f90 works with gfortran -cpp main.f90 -o main : program main implicit none #ifdef DEBUG print *, "I am in debug mode" #endif print *, "hello world!" end program main But the following throws an error: program

问题 I'm very new at JMeter issues. In a test script i have a BeanShell PreProcessor element that updates some variables previously defined at a "User Defined Variables" element. Latter those variables are used in "Http Requests". However, the value that is used in the http request is the default one. The scripts seems to be working due to some debug print(); My question is if it's necessary to delay the script to be sure that the BeanShell finishes? Thanks a lot for your attention 回答1: There is

问题 I have recently moved from vs 2013 to vs 2017. we have this project that has these preprocessor Definitions: WIN32 DRG_BUILD_DLL WINVER=0x0600 Now in atlwinverapi.h I get this error that InitializeCriticalSectionEx is not a member of global namespace. Any ideas why this problem is happening? #if (NTDDI_VERSION >= NTDDI_VISTA) && !defined(_USING_V110_SDK71_) && !defined(_ATL_XP_TARGETING) // InitializeCriticalSectionEx is available in Vista or later, desktop or store apps return :

问题 Think about a preprocessor which will read the raw text (no significant white space or tokens). There are 3 rules. resolve_para_entry should solve the Argument inside a call. The top-level text is returned as string. resolve_para should resolve the whole Parameter list and put all the top-level Parameter in a string list. resolve is the entry On the way I track the iterator and get the text portion Samples: sometext(para) → expect para in the string list sometext(para1,para2) → expect para1

问题 I was trying to: #define CommonAppData {commonappdata} but it yields: Compiler Error [ISPP] Expression expected but opening brace ("{") found. How to achieve this with Inno Setup PreProcessor? 回答1: {commonappdata} cannot be expanded at compile time, i.e. when the pre-processor runs because it is only known at runtime: It identifies the common application data directory on the machine where the compiled installer is run . Maybe if you could clarify how you intend to use that define we might be

问题 The following preprocessor macros (the usual suspects: testing on empty argument list and counting number of arguments) run without warnings on gcc/clang but fail on Microsoft VisualC: // IS_EMPTY() returns nothing if the parameter list is empty and a single ',' (comma) otherwise. // The parameter list can have up to 32 parameters #define IS_EMPTY(...) IS_EMPTY1(__VA_ARGS__) #define IS_EMPTY1(...) IS_EMPTY2(DROP_PARAMS __VA_ARGS__ (,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,EMPTY)) #define IS_EMPTY2(..

问题 for our project we always used one source file for both platforms: iOS and OS X. Right now I am migrating to swift. Unfortunately there is some files which need import Cocoa and on iOS import UIKit previously we did #ifdef __MAC_OS_X_VERSION_MAX_ALLOWED #import <Cocoa/Cocoa.h> #else #import <UIKit/UIKit.h> #endif Do you know how this can be done in swift? I don't like to write each class twice just because there is no macros anymore. Thanks in advance Jack 回答1: Use: #if os(OSX) import Cocoa

问题 When I add a Preprocessor Macro in XCode 4 to one of my targets, it is used and conditional compilation occurs as I expect it to. However, if I move that setting to the project level and out of one of my targets the preprocessor macro apparently is ignored and not used at all. I verified that the macro is defined at all if I put it in the project's build setting through logging that is only compiled in when that macro is enabled. How can that be? System: OS X Lion, XCode 4.1 build 4B110,

问题 All, I'm trying to use Keras to do image classification on two classes. For one class, I have very limited number of images, say 500. As for the other class, I have almost infinite number of images. So if I want to use keras image preprocessing, how to do that? Ideally, I need something like this. For class one, I feed 500 images and use ImageDataGenerator to get more images. For class two, each time I extract 500 images in sequence from 1000000 image dataset and probably no data augmentation
