compilation

问题 How come code written in Java needs to be compiled in byte-code that is interpreted by the JVM, but code written in a language like JavaScript does not need to be compiled and can run directly in a browser? Is there an easy way to understand this? What is the fundamental difference between the way these two languages are written, that may help to understand this behavior? I am not a CS student, so please excuse the naivete of the question. 回答1: Historically, JavaScript was an interpreted

问题 I have a makefile and all I want to do is to make my executable go to the folder created in the one I have all the files in. So let's say I have a folder in which there are some .cpp files, I create a folder in this folder called OUTPUT (during compilation) and I want my exec made out of those cpp files to go into this folder. How do i do that? Thanks in advance! 回答1: OUTPUT/exec: foo.cpp bar.cpp baz.cpp g++ $^ -o $@ Refinements are possible, but this will get you started. 来源： https:/

问题 I'm using Roslyn to emit a CSharpCompilation object in Visual Studio to a file. The DLL that is generated does not contain any assembly info other than the assembly metadata, and I'd like to add the version and sign it if possible. How can these be done with Roslyn? 回答1: You need to include source code which sets the Assembly* attributes just like in the VS C# project templates. If you have done that, the .NET version info is set. You can read that information with Reflection or tools like

问题 I'm trying to understand how works the option -classpath when compiling from command line. I try from parent of mydirectory : javac -cp mydirectory/subdir Hello.java But compiler says: javac: no sources files How does -cp ( -classpath ) work?? What am I doing wrong? If I make it from subdir directory: javac Hello.java then compiles properly. 回答1: javac TestProgram1.java TestProgram2.java TestProgram3.java You can use a wildcard to compile all the files in a folder, like this: javac *.java If

问题 I have a c++ project having two src folders. Source file in folder 1 may need to include header file in src folder 2. Is it possible? or how should I write my Makefiles? thanks 回答1: Depending on how closely the two folders are related (eg, if they're the same project), then it can be as easy as: #include "../otherfolder/header.h" If they're separate projects, then it's customary to simply add the other project's header directory to your project's header search path, and include the header

问题 I would like to compile a python3 package into a distributable binary form (without sourcecode) from within the x64 Native Tools Command Prompt for VS 2019 using python 3.6 (64bit). However, i have problems specifying the correct paths to the files the package should contain. The produced folder structure in the site-packages directory is all wrong and not what i expect from my source folder structure and my setup.py . It seems for me that the modules from the top level package are treated

问题 My Makefile compiles all the files everytime I run it though the files have not been changed. I know that this question has been asked several times but none of the provided solutions seem to work for me. I am new to Makefile and most of the times I do not understand the jargon used in the solution. Also, I want to save all the generated .o files under the folder 'obj' Here is my folder structure project (-) gen (-) display (-) .c and .h files logic (-) .c and .h files lib (-) include (-) .h
