compilation

问题 I'm developing a small web frontend in Grails. It is basically a "ultra light-weight" client app that is connected async through JMS. I have two dependencies in the project that I would like to pull from a Maven repository. They is activemq and acme-adapter-api , a in-house dependency, not available at the remote repository. I set up my BuildConfig.groovy ( Grails 1.2M4 ) file like this, in order to access my dependencies: repositories { grailsPlugins() grailsHome() mavenCentral() mavenRepo(

问题 I originally asked this question on ServerFault and haven't got any response and I figure it's programming related so, here goes... A while ago a large client of ours moved to a single hosting provider who spec'd out a software environment which would be consistent accross all the live servers. Amongs other things this includes Apache 2.2.8 and PHP 5.1.6. We had an ubuntu 8.04 server for development and these versions of Apache and PHP are not the default installed. So I had to compile them

问题 I am writing some unit tests in which I need a fake xml file. I can create that file and require it to be deployed with the unit tests, but experience shows that at my office it's a lot of headache. So I decided that the file will be created by UT's. StreamWriter sw = new StreamWriter(testFileName); sw.Write(contents); sw.Close(); Now the problem is the contents string. It is virtually a long xml, something like this: string contents = @"<?xml version="1.0" encoding="windows-1251"?> <blah>

问题 I've read through quite some documentation and questions but I'm still confused about this. In the Profiling section of the documentation it's suggested to first run the target function in the REPL once, so that it's already compiled before being profiled. However, what if the script is fairly complicated and is inteded to be run in the command line, taking arguments? When the julia process finishes and I run the script the second time, is the compilation performed again? Posts like https:/

问题 I've gotten myself into having to maintain some C project which should also compile on older platforms. At the moment, for some platforms, the macro _POSIX_C_SOURCE is defined. I was wondering - if it's acceptable to have it defined, should I not just define it always, on all platforms? And perhaps with the highest relevant value? To generalize, I suppose I'm asking: When and under what conditions should _POSIX_C_SOURCE be used? 回答1: _POSIX_C_SOURCE makes different functionality available.

问题 I know that we can compile program as C++ using g++ compiler. But g++ compiler defaults to 98 version. To run it as C++ 14, we need to add -std=c++14 in terminal. Sublime Text is considered a valuable editor for competitive programming due to its light weight and features. In these competitions time is important and thus the time is wasted in copying in text file and then running from terminal. C++ 14 features a rich library and other important features in comparison to 98. Thus one would

问题 When compiling OpenSSL you can add 2 options (from INSTALL in the OpenSSL sources): Configuration Options --------------------- There are several options to ./config (or ./Configure) to customize the build: --prefix=DIR Install in DIR/bin, DIR/lib, DIR/include/openssl. Configuration files used by OpenSSL will be in DIR/ssl or the directory specified by --openssldir. --openssldir=DIR Directory for OpenSSL files. If no prefix is specified, the library files and binaries are also installed there

问题 I'm not an expert C++ programmer, and i have been recently doing a trick thing in C++ which is causing me the below issue. Objective of my task: Specific non system thread (cooperative threading actually) safe module is duplicated to create a system thread safe version to support different needs in the system. But instead of creating sys_XXX functions to keep the compatibility, we have decided to create a namespace to protect the system thread version in a C++ header file. I can actually

问题 Although I found many answers and discussions about this question, I am unable to find a solution particular to my situation. Here it is: I have a main program written in FORTRAN. I have been given a set of python scripts that are very useful. My goal is to access these python scripts from my main FORTRAN program. Currently, I simply call the scripts from FORTRAN as such: CALL SYSTEM ('python pyexample.py') Data is read from .dat files and written to .dat files. This is how the python scripts

问题 In the preferences for IntelliJ 2018.1 (Build, Execution, Deployment > Compiler > Java Compiler) is an checkbox labeled: Use '--release' option for cross-compilation (Java 9 and later) I found for information when doing an internet search. The "?" help icon give a 404 error when clicked. What is the purpose/function of this option? 回答1: The help section can be found here: By default, this option is selected. IntelliJ IDEA deduces from project settings when the cross-compilation is needed and
