When I try to batch build my project, I encounter this error while I have enabled the clr runtime support.
My project can run with no problem and I only receive this error when I try to make a batch build.
I have made a lot of searched in google but most results are about enabling the clr option.
I'd like to know how I can fix this problem.
This is the kind of problem you'll run into when you make project setting changes while you are debugging your project. Settings are stored per configuration. A common mistake is to make the change for the Debug configuration but forgetting to make the same change for the Release configuration. Kaboom when you then try to get the Release configuration built, as would happen when you use Batch Build.
Go slower. Project + Properties, Configuration Properties, General. Note the combobox labeled "Configuration" in the upper left corner. It probably now says "Active (Debug)". Change it to "Release". And note how the "Common Language Runtime support" setting changes as you flip back and forth. Make them the same, /clr. Use Build + Configuration Manager to make the Release build the default configuration and use Build + Build to build it. Test it.
There might be other settings you've changed that need to be corrected for the Release build as well.

Motivation
PreBuild to disable compilation of redundant projects for faster compilation cycle.
Background
I have a VS15 ALL solution that contains many projects.
I have a single project, PreBuild, that all the other projects are dependent on, meaning, this PreBuild compiles first.
In addition, we also have a PostBuild project that do some more work once binaries are ready.
All projects are configured to build in Release mode (which is desired).
When a team member wants to release some binaries, he hits F7, Build Solution.
Now, the PreBuild, activates a separate dedicated process that calculates which projects should be released. The nature of the calculation is irrelevant to this discussion.
Problem
Out of the many many projects, it is often the case that only a few projects needs to be released. However, once the PreBuild process is done, ALL the projects are will compile which is very time consuming.
Question
Is it possible, after a solution build had started, to change the released projects?
Suggested unwanted approaches
A developer handpicks only the relevant projects and only build those.
PreBuild Kill & Revive. Once desired projects are calculated, PreBuild kills the VS15 process and activate a cmd compiling only the relevant projects.
Suggested approach
Change file ALL.sln and remove the the unwanted projects.
This would work had I changed that file prior to the process start but I'm not sure it would work if this change occurs during the process.
The simplest way I can think of, while still keeping most of the current infrastructure in place: have a dedicated project which invokes the release build (by calculating dependencies and invoking msbuild) and configure VS so it can be select just that project for a build. All from within your ALL.sln so the rest of the features remain. Steps:
Get rid of the PreBuild/PostBuild projects. I assume the PostBuild you mention is also meant for the actual release builds; if not just leave it there. Note by not requiring all projects to depend on the PreBuild project you already got rid of one maintainance burden.
Add one single project which will do the release building, say ReleaseBuild. Such name is also better than having PreBuild/PostBuild projects since it clearly states the intent of the project. A Makefile project is suitable, though technically it could be as simple as an msbuild file with just one Build target. Configure the build command line to do whatever is needed, i.e. figuring out what to build then build. For the sake of an example: say you use Powershell to do this you would configure the build commandline to be
Powershell -NoProfile -File BuildRelease.ps1 $(Platform)
and BuildRelease.ps1 contains something like
$projectsToRelease = CalculateMyProjectsForRelease()
$platform = $Args[0]
$projectsToRelease | %{& msbuild $_ "/p:Configuration=Release;Platform=$platform"}
In Configuration Manager add an extra Configuration called Deploy or so. This will be used to select what to build: you probably have Debug and Release configurations now already. Those stay in place, and are simply used to build everything. The idea is this extra configuration will take care of building the actual release. This is fairly consistent with the standard way of working in VS and easy to discover and understand for newcomers. Using the checkboxes, make it so that when the Deploy configuration is selected only the ReleaseBuild is built and none of the others whereas when Debug or Release is selected the ReleaseBuild project is not built. Looks like this:
To build a release, select Deploy from the configuration drop down menu in the VS toolbar and hit F7 (or whatever way you use to invoke Build Solution). Any build errors/warnings will be parsed and shown as usual in the Error List.
This is also easy to extend: suppose you only have a couple of release build versions just add more configurations like DeployA DeployB DeployC and adjust the build command line for them.
I have a set of environment variables I use in all my projects, as well as custom make targets that I use for my builds in Eclipse (Mars 4.5.0). In order not to have to set these every time, I made a new configuration from a configured project under Project->Properties->C/C++ Build. However, when I now select that configuration in a new project and hit apply or OK, I find the changes haven't taken effect, and if I open up Project->Properties again, I see it has reverted to the default.
What am I doing wrong?
This isn't quite satisfactory, but in case others have the same issue, I found that one way to deal with the issue is to simply delete the default configuration, so that your custom configuration is the only option. I'm curious whether this is a bug or whether I'm going about this the wrong way...
Why do you have to build under release configuration, followed by another build of same project in debug configuration in VS2010 C++ to be able to have the debug see updated code?
You don't have to. You only have to build the configurations which you want updated. That is, if you change your code and want to have Debug "see" the updated code, just build Debug. You don't have to build Release.
Of course, then your Release build will not "see" the new code until you build it again.
If you're asking why they have to be built separately - because the code generated by each of these settings is fundamentally different, so there's now way to "reuse" it somehow.
Because each build links to different core libraries, uses different compiler/linker settings, creates different assembly code, and hence different executables, the release one probably more optimized. Btw there is a Batch Build menu item under the Build menu allowing to build everything with one click.
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.
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.
