We just got a new developer and I'm trying to set him up with Dev Studio 2005 (The version we all use at this office), and we're running into a weird problem that I've never seen before.
I have some code that works perfectly on my system, and he can't seem to get it compiled. We've tracked the issue down to his copy of dev studio ignoring the preprocessor directives.
For example, in the project properties under C/C++|Preprocessor|Preprocessor Directives, I add DEFINE_ME. Which should translate to a /D"DEFINE_ME" for the compiler. And it does in my development environment, but it doesn't on his.
I verified that when he checks out the code from the source repository, that he has the same version of the code I do. And if I look in his Project Properties, all of the directives are there. For some reason they're just not getting passed down to the compiler.
Any Ideas?
I recently ran into the same symptom with VS2005. Ultimately I was able to resolve it by explicitly adding my preprocessor defines via the Command Line - Additional options dialog:
Configuration Properties -> C/C++ -> Command Line
When I added '/DPROPERTY' there it was recognized at compile time, whereas adding it under 'Preprocessor -> Preprocessor Definitions' did nothing. Oddly the Command Line dialog did show that Visual Studio was adding the property to the command line, albeit in the form '/D "PROPERTY"'.
Unfortunately schedule pressure being what it is I have not been able to dig into the issue deep enough to figure out what the underlying issue was/is, nor why it seems to work out of the box for some of our projects but not others. Nonetheless the workaround above is worth a shot if you're having this symptom.
Also, credit where credit is due: the idea came from this thread.
Make sure that the project configuration which is being built in the selected solution configuration is the same as the one you're configuring the properties for, and/or that you're configuring the properties for all project configurations. A common problem with new VS installations is that the current active solution configuration is system-specific, and may default to something not matching yours (eg: Release vs Debug).
You can see the project config in the build output, and/or check it in the Configuration Manager.

I am new to VS Code and, coming from VS, I'm struggling to understand how to set up different configurations using the Microsoft C/C++ extension. I followed the documentation, but it seems to me that the content in c_cpp_properties.json is only affecting Intellisense and has no correlation to the actual build, which is set up in tasks.json. The configurations I enter are showing up and selectable at the lower right of the editor window: Intellisense reflects this by apparent knowledge about include folders, etc. However, when I build or run, they don't have any effect, I get errors such as "No such file or directory" for included files. As far as I see it, this is not mentioned in the documentation at all.
How can I make use of the actual selected configuration for the build system?
My current preferred C++ environment is the free and largely excellent Microsoft Visual Studio 2005 Express edition. From time to time I have sent release .exe files to other people with pleasing results. However recently I made the disturbing discovery that the pleasing results were based on more luck that I would like. Attempting to run one of these programs on an old (2001 vintage, not scrupulously updated) XP box gave me nothing but a nasty "System cannot run x.exe" (or similar) message.
Some googling revealed that with this toolset, even specifying static linking results in a simple hello-world.exe actually relying on extra .dll files (msvcm80.dll etc.). An incredibly elaborate version scheming system (manifest files anyone?) then will not let the .exe run without exactly the right .dll versions. I don't want or need this stuff, I just want an old fashioned self contained .exe that does nothing but lowest common denominator Win32 operations and runs on any old win32 OS.
Does anyone know if its possible to do what I want to do with my existing toolset ?
Thank you.
For the C-runtime go to the project settings, choose C/C++ then 'Code Generation'. Change the 'runtime library' setting to 'multithreaded' instead of 'multithreaded dll'.
If you are using any other libraries you may need to tell the linker to ignore the dynamically linked CRT explicitly.
My experience in Visual Studio 2010 is that there are two changes needed so as to not need DLL's. From the project property page (right click on the project name in the Solution Explorer window):
Under Configuration Properties --> General, change the "Use of MFC" field to "Use MFC in a Static Library".
Under Configuration Properties --> C/C++ --> Code Generation, change the "Runtime Library" field to "Multi-Threaded (/MT)"
Not sure why both were needed. I used this to remove a dependency on glut32.dll.
Added later: When making these changes to the configurations, you should make them to "All Configurations" --- you can select this at the top of the Properties window. If you make the change to just the Debug configuration, it won't apply to the Release configuration, and vice-versa.
I've had this same dependency problem and I also know that you can include the VS 8.0 DLLs (release only! not debug!---and your program has to be release, too) in a folder of the appropriate name, in the parent folder with your .exe:
How to: Deploy using XCopy (MSDN)
Also note that things are guaranteed to go awry if you need to have C++ and C code in the same statically linked .exe because you will get linker conflicts that can only be resolved by ignoring the correct libXXX.lib and then linking dynamically (DLLs).
Lastly, with a different toolset (VC++ 6.0) things "just work", since Windows 2000 and above have the correct DLLs installed.
In regards Jared's response, having Windows 2000 or better will not necessarily fix the issue at hand. Rob's response does work, however it is possible that this fix introduces security issues, as Windows updates will not be able to patch applications built as such.
In another post, Nick Guerrera suggests packaging the Visual C++ Runtime Redistributable with your applications, which installs quickly, and is independent of Visual Studio.
I'm trying to alter the default property sheet on a new install of Visual Studio 2010 for C++ projects. Just trying to add a few directories (for Boost etc.) and optimisation settings for release builds, basic stuff like that. Obviously there are some settings that I want to be different for different configurations. Problem is that whatever I try from the property manager window of my project, everything I do seems to affect both configurations.
I tried multi-selecting both -> right click -> properties initially, to set up common settings, and that did exactly the same thing as selecting Microsoft.Cpp.Win32.User under either debug or release. So everything affects both configs.
Now, as I understand it, Microsoft.Cpp.Win32... is a single file (at least, a single file for x86 configs, single file for x64 etc.) so the fact that I can't change the configs individually actually makes some degree of sense. But if I can't do it that way, how can I do it?
Appreciate any advice!
Short answer: you can't. See comment discussion under question.
I have a Visual Studio 2008 solution with a number of projects that all define _HAS_ITERATOR_DEBUGGING=0 in the Preprocessor Definitions setting in project files. But this only seems to work on some of the projects, while others still get compiled with iterator debugging enabled.
I have checked every file in the solution, and nowhere is _HAS_ITERATOR_DEBUGGING defined other than the project settings.
Adding #define _HAS_ITERATOR_DEBUGGING 0 to the top of each stdafx.h in the solution works around the issue, but I would like to know why setting this in the project Preprocessor Definitions section is not working some of the time. Any ideas?
One thing that bites me every now and then is that project settings can easily become different between different configurations (Release vs. Debug for example). Make sure the setting is there or the configuration you're building. And of course that the define is spelled correctly...
For the projects that are having the problems, take a look at the build log (BuildLog.htm - a link to it shows up in the Build Output window) and make sure the
-D "_HAS_ITERATOR_DEBUGGING=0"
option shows on the compiler command line (actually in the response file that has the command line options passed to the compiler).
I'm using Eclipse with C++ code via linked resources on Linux. The code analysis index seems to be corrupted (Goto definition lands the cursor close to, but not on, the definition) Refreshing resources doesn't fix it, neither does restarting Eclipse.
Is there a way to flush the index and rebuild it?
Right-click on your project, go under the Index submenu, and choose either "Rebuild," "Update with modified files," or "Freshen all files."
I don't know the difference between those three options, but one of "Update with modified files" or "Freshen all files" usually fixes it for me.
Also, I'm sure you've already done this, but make sure that you're running the latest version of the Eclipse CDT. Current versions seem to have much more reliable indexing than previous versions.
From http://dev.eclipse.org/mhonarc/lists/cdt-dev/msg10390.html, the differences between "Rebuild," "Update with modified files," or "Freshen all files":
Rebuild: Works for entire projects, only. Clears the index and indexes
the files from scratch. When cancelled it leaves you with an empty or
partial index.
Update with Modified Files: Works on a resource
selection. Checks on individual files whether the timestamp or the
scanner-config has been changed and updates the index for the changed
files.
Freshen All Files: Works on a resource selection. Updates the
selected files in the index. The index is not cleared, it is safe to
cancel the operation.
Go to your project properties -> C++ general -> Indexer.
Do this with 'project specific settings',
(or on 'Configure Workspace Settings...').
Deselect 'Enable Indexer' hit Apply.
Select 'Enable Indexer' hit Apply.
This should completely wipe out and rebuild the index.
Neither of the above worked for me (Eclipse Indigo), index still broken and refusing to rebuild properly. Until applied this one:

The crucial bit of the linked post is this:
Eclipse no longer treats your project as a C++ project. Choose menu File/New/Convert to a C/C++ project. It takes a while to index the source code.
I still wonder how Eclipse can uncontrollably shoot itself in the foot like that. I suspect that installing additional packages can trigger it. Perhaps JavaScript support in my case.
delete only the .pdom file under .metadata.plugins\org.eclipse.cdt.core helps, I got the indexer screwed after upgrading Neon.2 to Neon.3 and this seems to solve the problem.
(this comment already exists above but am not allowed to confirm it up there).
I found that I had the global indexer set to 'Use the build configuration specified in the project's indexer settings',
and the project's indexer set to NOT use project specific indexer settings.
Regardless, it was using the same fixed configuration for the indexer regardless of which configuration I had selected.
The fix:
Window-Preferences, C/C++, Indexer. Select "Use active build configuration" in section "Build configuration for the indexer".
Happy days.
Did you try adding -clean to the command line for the eclipse executable?

I started with trying Josh Kelleys and mmmmms answers without any luck, but I finally fixed it by checking my include paths.
One way to see them are in the Project Explorer, expand project and there should be an entry "Includes". Inside that, check for a small yellow warning triangle on each include path. If that triangle is present eclipse most likely doesn't recognize the path.
The include paths are edited through right-clicking on "Your project" in the Project explorer, then choose "Properties" --> C/C++ General --> Paths and Symbols --> Includes.
I see three language options, Assembly, Gnu C, Gnu C++. Choose the correct one before starting to add paths (likely Gnu C++). After adding all the paths, -->Apply --> Ok and rebuild index if you're asked to.
My erroneous workspace paths looked like MyProject/MyProject/folder when it was supposed to be MyProject/folder.
For me the "Problems"-view is always slow to update, even after rebuilding index. To be sure that the error is still there, double-click the problems entry so that eclipse opens/reloads the file in question. This often seems necessary for me to update the "Problems" view.
I don't really know if it was eclipse or my scm that messed it up. Anyway, hope it helps someone!
I use Luna and builds with an external makefile.
