compilation

问题 Let’s say the runtime environment (version 1.6.0_01-b06) is already in place, but since I lack administrative privileges in this particular PC, the JDK can’t be installed. So, is there any portable JDK or standalone Java compiler for Windows that doesn’t require installation? 回答1: You might try taking the tools.jar file from the JDK (you would have to copy it over from another machine) and see if that worked. javac is essentially a small exe that starts the VM with the specific class for the

问题 I have in Android Studio a complex project establish by five modules. Four of them act as independent apps, but one of them is the base code for the rest. This way, I can have a big common core and four separates codes for every app (these apps share the shame model data and api connection). My question is if it is possible rebuilding, cleaning or syncing just for one module, non the entire project in Android Studio. Thanks! 回答1: Nowadays with Android Studio you can use build -> make module

问题 I was wondering if there is a way to conditionally compile entire namespaces in C#. Or am I left with having to explicitly decorate each source file within the namespace with the preprocessor directives to exclude it? In sub-versions of my application the code in various namespace is simply not required and I would like it excluded. Thanks in advance! 回答1: If your namespace is in a separate assembly which doesn't contain anything else you can use the Configuration Manager for your specific

问题 I'm performing some source processing between C preprocessing and C compilation. At the moment I: gcc -E file.c > preprocessed_file.c . Do more stuff to preprocessed_file.c . Continue the compilation with preprocessed_file.c . If you attempt to compile preprocessed_file.c as you would if it was normal C (step 3) you get lots of the following: /usr/include/stdio.h:257: error: redefinition of parameter ‘restrict’ /usr/include/stdio.h:257: error: previous definition of ‘restrict’ was here /usr

问题 I'm trying to change the port this server runs on via eclipse but no matter what I do it doesn't seem to autocompile/autocomplete my java file? Any ideas? 回答1: For auto-build, go to Project->Build Automatically . Build automatically should be checked for auto build to happen. For auto-complete(content assist) go to Windows->Preferneces . In there follow Java->Editor->Content Assist int he left tree and configure as you feel like. 来源： https://stackoverflow.com/questions/5373993/eclipse-wont

问题 I have to compile a C++ project and make it run as 64bit application to avoid the 32bit memory limitation. My IDE is Visual Studio 2013 Express for Windows Desktop I couldn't find a clear answer on how to do this, anybody has a solution ? 回答1: From command line, load the cross-compiler : call %VSDIR%\VC\vcvarsall.bat x86_amd64 Open solution %VSDIR%\Common7\IDE\WDExpress.exe solution.sln and that's it. The x86_amd64 switch to a compiler (which happens to be a 32bit program) that produces 64bit

问题 Helo, i have a strange behavior in Visual Studio.

问题 I have doubt. I know that it is possible to call from a cpp file an R function. But it is possible to compile that cpp file (that has an R function inside -from a package, for example caret -) into a .so or dll ? If it is possible. How does having a chuck of R code inside works. Does the compiled code calls the R interpreter before it compiles or it does not need to? Thanks in advance 回答1: Yes, you can embed R inside of C or C++ application. The API is old, stable, somewhat documented and a
