portability

问题 I hop from computer to computer, and want to be able to code on all of them, so i have this usb-drive... And i installed eclipse-portable on it, and then installed PyDev, which for some reason refuses to work, have any of you got a idear? This is the error it gives me: Plug-in org.python.pydev was unable to load class org.python.pydev.editor.PyEdit. And the detailed version is: org.eclipse.core.runtime.CoreException: Plug-in org.python.pydev was unable to load class org.python.pydev.editor

问题 I am using several P/Invokes under .NET. However, I want my library to work both in Windows and Linux, preferably with the same binaries. Since the native library I depend on is available on multiple platforms, I was hoping to just have them along with my managed library's binaries. Right now I'm using something like this: [DllImport("/usr/lib/libMYLIBNAME.so.1")] But this obviously only works for Linux. I was considering that I could possibly copy that binary from /usr/lib and distribute

问题 Sometimes, I want to write an simple application which will works on any Windows machine, without installing any programs or components (ex. .NET Framework), in a C# or Java like programming language. How can I do this? Thanks. EDIT: Added the 'like', sorry... 回答1: Both c# and Java require runtime libraries that have to be installed separately from the application. You could write a standalone application using Delphi for example. 回答2: Yes, If you use c++ you can use more core API's like

问题 I have two tables. CREATE TABLE profile_table ( profile_id NUMBER(10,0) PRIMARY KEY, creator_manager_id NUMBER(10,0), lastupdate DATE, description VARCHAR2(255 BYTE), profile_name VARCHAR2(255 BYTE), creatorname VARCHAR2(255 BYTE) ); CREATE TABLE profile_basket_table ( profile_id NUMBER(10,0), from_id NUMBER(10,0), action NUMBER(10,0), constraint pbt_pk_constraint PRIMARY KEY(profile_id, from_id), constraint pbt_fk_constraint FOREIGN KEY(profile_id) REFERENCES profile_table(profile_id) ); I

问题 I am using signed to unsigned byte(int8_t) cast to pack byts. uint32_t(uint8_t(byte)) << n This works using GCC on Intel Linux. Is that portable for other platforms/compilers, for example PowerPC? is there a better way to do it? using bitset is not possible in my case. I am using stdint via boost 回答1: If you are using boost/cstdint.hpp from the Boost Integer library, then yes, the typedefs are portable (cross-platform.) The boost/cstdint.hpp header is meant to implement C99 stdint.h

问题 I'm thinking about using PhysicsFS in my game engine project, but I'd like to first make sure it's entirely platform-independent. That's because I'd like to port my engine to some rather obscure platforms after I'm done with the Windows code (Wii Homebrew, for example). 回答1: In accordance with the official specs the developers provide on their site it: Compiles/runs on GNU/Linux (x86, PPC, MIPS, Sparc, Alpha, Itanium, and x86-64 tested; gcc). Compiles/runs on Windows, Win95 and later (x86

问题 Let's say I have a text file, it contains batch commands. How can I run that text file as a batch file from within one, without renaming it. I want too keep a portable aspect too it, so no registry keys or such. The reason for no renaming is too prevent leftover unrenamed files upon unexpected closure. 回答1: type some.txt>temp.bat call temp.bat del /q /f temp.bat Is creating a temp file cheating?It's not mentioned as restriction in the question.Though you can loose the %ERRORLEVEL% because of

问题 I created a portable class library and then targeted it at .NETStandard 1.5 from the project properties. I then created a second project with the exact same project settings, but added code to use for invoking and testing the code in the first project. But I have been unable to add MSTest to use for triggering execution. I tried using the guidance at stack overflow # 41350323 but ran into problems. Wondering if anyone out there has been able to use MSTest for unit testing portable

问题 I have not worked with static libraries before, but now I need to. Scenario: I am writing a console app in Unix. I freely use std::string everywhere because it's easy to do so. However, I recently found out that I have to support it in Windows and a third party application would need API's to my code (I will not be sharing source, just the DLL). With this in mind, can I still use std::string everywhere in my code but then provide them with char * when I code the API's? Would that work? 回答1:

问题 The dllmap configuration file entry is used in Mono to map requests for windows DLLs to Linux (.so) libraries. But it seems that if Microsoft's .NET framework tries to parse a configuration file with such an entry, an error occurs because it doesn't understand "dllmap". I think everything else in my distribution can be distributed unchanged on both Linux and Windows XP. Of all the portability involved in this, is this configuration entry really the downfall -- the one non-portable piece? Isn
