compilation

问题 I downloaded Rebol/View (vesion 2.7.8) Linux x86 libc6 2.3 version from http://www.rebol.com/downloads.html and it is working all right as an interpreter on Linux (Debian Stable 9). Is it possible to compile the code to executables? I tried checking the options, and compile to executable option does not seem to be there: $ rebol -v --help The command line usage is: REBOL <options> <script> <arguments> All fields are optional. Supported options are: --cgi (-c) Check for CGI input --do expr

问题 I am using the gcc compiler. My project source tree looks like somewhat like this test$~: tree . . |-- folder | |-- hello.cpp | `-- hello.h `-- main.cpp 1 directory, 3 files test$~: The file main.cpp contains the main() function and all the functions invoked by main.cpp lie in the directory named folder So far in all my little projects I never had to put some source code under a sub-directory. What I am looking for, in short, is some gcc command for recursive compilation in sub-directories

问题 I've learned that a process has the following structure in memory: (Image from Operating System Concepts, page 82) However, it is not clear to me what decides that a process looks like this. I guess processes could (and do?) look different if you have a look at non-standard OS / architectures. Is this structure decided by the OS? By the compiler of the program? By the computer architecture? A combination of those? 回答1: Related and possible duplicate: Why do stacks typically grow downwards?.

问题 Pretend I have a table with 2 columns. _id and name. _id is the primary key and I do not want to set this value manually. I want to perform an insert of name="john," and let the program create my own _id. I am unclear what "index" to use when inserting and how many question marks to use. Does this code do the job? Should the index for john be 1 or 2? String TABLENAME = "table"; SQLiteStatement statement = db.compileStatement("INSERT INTO "+TABLENAME+" VALUES(?);"); statement.bindString(1,

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 8 years ago . Here is the deal... I want to make a program (exe) that will take the user defined settings and make a custom (exe) file for the user inside of the previously mentioned program (exe). Wanted to know if there was

问题 So basically what I need isn't a specific code (of course that would be great), but just an idea and methods on how to achieve my goal. 1) I have to create a program in C++ , which generates a little example of C++ code, that is each time a bit different. (This causes no problems for me, I will use a template and randomize some variables in the code, which will make it unique every time.) 2) I will display the generated code and the user will have to type in, what he thinks the code prints

问题 I am currently trying to compile and build QT for Embedded Linux on an Ubuntu box for ARM architecture. So far, I have run into MANY errors while trying to MAKE. The biggest one being a 2000 line C++ function which caused a compiler error. What are other peoples experiences with this and how did you fix it? 回答1: My experience has always been favorable, given: You must follow every single instruction in the installation instructions for Qt, without exception. Every time I've run into

问题 In short, what are the steps that one needs to take in order to modify the source of the connector and install it in Windows? I have the MySQL Connector/.NET Version 6.1.2 installed on my machine, but I'm getting an exception for every DateTime with a value of '0000-00-00'. This exception breaks my application. As I solution, I downloaded the source code for the connector and changed the exception so that instead of throwing an exception, it returns the date '0001-01-01 00:00:00'. Although I

问题 I have been using tsc, but see that angular.io emphasizes ngc. I am wondering if there are advantages to either or if I should choose one over the other. Thanks in advance. 回答1: tsc and ngc have different purposes and it's not about selecting one over the other. tsc is a TypeScript compiler, and you need it to generate JavaScript if your app is written in TypeScript. ngc is an Angular-specific compiler. It doesn't turn the TypeScript code into JavaScript. It does a "finishing touch" to make

问题 i use ifort and gfortran to compile my Fortran program. However i also use a coworkers source and he has got a lot of unused variables. How can i suppress these for the compile, seeing as they are not really an error? However i dont want to disable -pedantic and -stan in the compiler options and thus want all the other warnings. cheers and thanks for the help 回答1: With ifort try -warn [no]unused . And, while I'm here, I suggest you remove unused variables. The compiler may not regard them as
