How to configure VS to compile only changed code

情到浓时终转凉″ 提交于 2019-12-03 12:23:54
I have very big solution, and it compiling every time I'm tring to debug. So I know that I can to disable building of all projects at all in solution configuration, but is there way to say to Visual Studion to compile only changed code? I sure that is. Thank you for ahead. Oliver As Marnix and Anton already said this is what VS normally does. But if you have a lot of projects within your solution which depend on each other and you make changes to a component which will be used by all or most of the other projects it has to build also the others again to make sure everything works as expected.

why do we need the shared library during compile time

孤者浪人 提交于 2019-12-03 12:21:49
Why we need the presence of the shared library during the compile time of my executable? My reasoning is that since shared library is not included into my executable and is loaded during the runtime, it is not supposed to be needed during compile time. Or Am I missing something? #include<stdio.h> int addNumbers(int, int); //prototype should be enough, no? int main(int argc, char* argv[]){ int sum = addNumbers(1,2); printf("sum is %d\n", sum); return 0; } I had the libfoo.so in my current dir but I changed its name to libfar.so to find that shared lib is needed at compile or it doesn't compile.

Can compile Scala programs but can't run them

问题 I am able to compile scala programs using scalac in terminal but I get the warning. Charless-Macintosh:src Charles$ scalac hello.scala Charless-Macintosh:src Charles$ scala HelloWorld No such file or class on classpath: HelloWorld Is this to do with .profile on scala. I'm pretty confused as to what is happening. Many thanks 回答1: The current directory is typically not in the classpath by default. So you need to give explicitly: $ scala -cp . HelloWorld 回答2: The problem is that you have set the

What is “object” in “object file” and why is it called this way? [duplicate]

问题 This question already has answers here : What's an object file in C? (5 answers) Closed 5 years ago . I was asked a question: "What is an 'object file'?". After looking at Wiki, I only know that it contains objects . But what are those objects and why someone called them that way? 回答1: Object files (or object code) are machine code files generated by a compiler from source code. The difference with an executable is that the object file isn't linked, so references to functions, symbols, etc

Properly compiling modules in subfolders (ocamlbuild)

为君一笑 提交于 2019-12-03 12:07:38
I recently decided to organize the files in my project directory. I moved the parsers I had for a few different file types into their own directory and also decided to use ocamlbuild (the as the project was getting more complicated and the simple shell script was not sufficient any longer). I was able to successfully include external projects by modifying myocamlbuild with some basic rules (calling ocaml_lib , I'll use ocamlfind some other time), but I am stuck on how to include the folder as a module into the project properly. I created a parser.mlpack file and filled it with the proper

Compiling and using Groovy classes from Java at runtime?

淺唱寂寞╮ 提交于 2019-12-03 12:06:27
问题 I have an app which I'd like to make extensible by letting users define classes in Groovy, eventually implementing some interfaces. The key aspect is that it should be interpreted/compiled at runtime. I.e. I need my app to take the .groovy and compile it. Doing it during boot is ok. Then, of course, my app should be able to instantiate that class. I see two solutions: 1) Compile while the app runs, put the classes somewhere on classpath, and then just load the classes, pretending they were

Scala (SBT) compile error: separate output paths (production, tests)

风格不统一 提交于 2019-12-03 11:52:48
问题 I have the same compile error on IntelliJ and Eclipse Scala: "Error:scalac: Output path C:\workspaces\ScalaProgFun\forcomp\bin is shared between: Module 'progfun-forcomp' production, Module 'progfun-forcomp' tests Please configure separate output paths to proceed with the compilation. TIP: you can use Project Artifacts to combine compiled classes if needed." Can someone help me with this, please? I have no idea how SBT works! This error happens on this project: http://spark-public.s3

How is clang able to steer C/C++ code optimization?

倖福魔咒の 提交于 2019-12-03 11:50:59
问题 I was told that clang is a driver that works like gcc to do preprocessing, compilation and linkage work. During the compilation and linkage, as far as I know, it's actually llvm that does the optimization ( "-O1", "-O2", "-O3", "-Os", "-flto" ). But I just cannot understand how llvm is involved . It seems that compiling source code doesn't even need a static library such as libLLVMCore.a , instead for debian clang packages depends on another package called libllvm-3.4 (clang version is 3.4),
