compilation

问题 I have a basic sbt project. I want to package two jars with the same source files, but compilation with different options. So one project, 2 compilations but with different options (scalacOptions) and 2 jars as output. I don't want to execute sbt twice, changing the options. Does anybody have an idea? 回答1: With something like this in build.sbt, you can run sbt compile2:package and produce both a jar from the compile config and compile2 config: val Compile2 = config("compile2") extend Compile

问题 Goal Detecting where comparisons between and copies of variables are made Inject code near the line where the operation has happened The purpose of the code: everytime the class is ran make a counter increase General purpose: count the amount of comparisons and copies made after execution with certain parameters 2 options Note: I always have a .java file to begin with 1) Edit java file Find comparisons with regex and inject pieces of code near the line And then compile the class (My

问题 I was writing a library for myself to help automate some really common tasks I've been doing in D for scripting from the command line. For reference, here is the code in its entirety: module libs.script; import std.stdio: readln; import std.array: split; import std.string: chomp; import std.file: File; //Library code for boring input processing and process invocation for command-line scripting. export: //Takes the args given to the program and an expected number of arguments. //If args is

问题 I am trying to deploy my Qt application and have run into a fatal error. The program works fine in the Qt editor, I can build and run it. After building my project in release mode and using windeployqt.exe to get the correct .dll's in the folder, I am treated to this error message. I get one for 5 different Qt .dll's. I found a way to remove this error by using the .dll's from Qt tools instead of the ones found in the compiler's bin directory. But, I am left with a remaining error like this.

问题 Hi i am a beginner learning objective c. i am finding an error "hello.m:1:34: Foundation/Foundation.h: No such file or directory" i came to know that i need to make a make file may i know how to make the make file please 回答1: No need to create a makefile. If you start MinGW from "All Programs -> GNUstep -> Shell" as Pax indicates above, you can just compile your .m file. My GNUstep installation is in c:\GNUstep\GNUstep\System. If yours is different, you should change the import of Foundation

问题 I'm running Ubuntu to compile a set of code which requires python 2.4. How can I setup a terminal launcher so that when I open that launcher all python related commands will use python 2.4 instead of the python 2.6 that is defaulted in Ubuntu? 回答1: Set a bash alias in that shell session: alias python=python2.4 (assuming python2.4 is in your $PATH of course). This way you won't have to remember to explicitly type the 2.4 a zillion times in that terminal -- which is what bash aliases are for!-)

问题 My work has over 24 pages in Latex. I need only the abstract and introduction in pdf. How can you compile only the first two pages? 回答1: I'd just make a new file with only the abstract and introduction and compile that. Actually, if this is not just a one-time thing, I'd use three files: absintro.tex : \begin{abstract} ... \end{abstract} ...introduction... onlyabsintro.tex : ... \begin{document} \include{absintro.tex} \end{document} fullreport.tex : ... \begin{document} \include{absintro.tex}

问题 I am building a Boost Python module (.so shared library file) which depends on another external library (STXXL) While I can build and import the example Boost Python modules, I run into problems when STXXL is thrown into the mix. Specifically when running import fast_parts in python I get ImportError: ./fast_parts.so: undefined symbol: _ZN5stxxl10ran32StateE This says to me that the STXXL library isn't being linked, but I am not sure how that could be as I am linking against it and the linker
