In a recent question on stubbing, many answers suggested C# interfaces or delegates for implementing stubs, but one answer suggested using conditional compilation, retaining static binding in the production code. This answer was modded -2 at the time of reading, so at least 2 people really thought this was a wrong answer. Perhaps misus...
I am writing a (very small) framework for checking pre- and postconditions of methods. Entry points are (they could be easily be methods; that doesn't matter): public static class Ensures { public static Validation That { get { ... } } } public static class Requires { public static Validation That { get { .....
Are there any preprocessor symbols which allow something like #if CLR_AT_LEAST_3.5 // use ReaderWriterLockSlim #else // use ReaderWriterLock #endif or some other way to do this? ...
Delphi 2007/2009 odd question here: It's possible, based on a component property defined in design-time, to include files in linking or leave them ? Example: If I leave SomeProperty true, when compiling, the unit SomeUnit will be included into my project. Otherwise it will not be included. My second approach to this problem is to depl...
How to do conditional compilation in Python ? Is it using DEF ? ...
Hi, depending on a compile switch (values are COMPILE_A or COMPILE_B), which is set in the form of an envorinment variable, I want to compile my application with different settings, like application name and splash screen. I got this far: In "Project / Settings / C/C++ / Preprocessor Definitions" I added $(COMPILESWITCH) (results in...
What is an alternative to autotools in Haskell world? I want to be able to choose between different configurations of the same source code. For example, there are at least two implementations of MD5 in Haskell: Data.Digest.OpenSSL.MD5 and Data.Digest.Pure.MD5. I'd like to write code in such a way that it can figure out which library is ...
We are developing two versions of an application. Not in the sense of a lite vs standard version of the application, where one version will have limited functionality etc. We will actually be displaying different types of information in the application, depending on the version (that's the best way I can describe it without going into to...
Currently our .net code is not processor specific, but it depends on libraries (Oracle/ODP.Net) which are. We've found a solution where we edit the csproj file directly, and put the references in to item groups with a Condition clause based on our selected build configuration. We have 32 bit debug/release and 64bit debug/release, and t...
I would like to write a cross-platform function in C++ that contains system calls. What conditional compilation flags can I check to determine which operating system the code is being compiled for? I'm interested mostly in Windows and Linux, using Visual Studio and GCC. I think it should look something like this: void SomeClass::SomeFu...
HI I want to know what's the difference between Release and Debug modes in Visual Studio while building a project? Thanks in Advance. ...
Hi can anybody please explain for me how and why /clr is incompatible with /mtd ? What is the alternative for this? What happens internally if I use /md or /mdd ? As far as I know we don't combinedly use /clr and /mtd. Can someone explain if there is a way to do this? And please explain me how and why /clr is incompatible with /mt and ...
Hi i hav solution explorer contains 2 proj.for one project i enable /clr with /mdd. for parent project i hav /mtd and no clr support.when i compiling this i am getting two linker errors including the below one Link warning link 4098:Default lib can conflict with other lib use /NODEFAULTLIBS library so my question how to use /NOD...

Windows provides only GetTickCount up to Windows Vista and starting from that OS also GetTickCount64. How can I make a C program compile with calls to different functions? How can I make a C compiler check whether a function is declared in the included header files and compile different portions of code depending on whether that particu...
How can I specify a Condition for a COMReference in my *.csproj file? The following does not appear to work: <COMReference Include="SomeComLib" Condition=" '$(Configuration)' == 'Debug' "> ... </COMReference> I have some COM references in a C# project in Visual Studio 2008. I would like them to automatically use non-isolation mode...
We need to define a conditional compilation symbol in a class library project. This should not be checked in the source control (it doesn't apply to all developers), so it should be defined in someplace other than the .csproj or the app.config file. How can this be achieved? ...
I am working on a VC++ project under VS2008. My resource files contain some pre-processor directives for conditional compilation. Some of the symbols controlling the conditional compilation are defined in stdafx.h. I need these symbols to be visible to the resource compiler as well. How do I make this happen? ...
We have the following in our codebase, in a component file: {$IFDEF ADO} FDatabase : TADODatabase; {$ELSE} FDatabase : TODBCDatabase; {$ENDIF} The reason is that for various legacy applications, one or the other type of database connection and set of classes is to be used. However, while configuring a new machine, it seems that our c...
I know that I can check the current state of Delphi's switch directives using this construct: {$IFOPT R+} Writeln('Compiled with range-checking'); {$ENDIF} Since I'm lacking of in-depth sources on how the Delphi backend compiler works, I'm not sure wether there is a way of changing the behaviour of a function depending on the st...
