I simply want to include a C++ header file in KDevelop by writing
#include <file.h>
However, KDevelop automatically corrects the above statement to
# include <file.h>
I have not been able to figure out where I can change this. I want the first version, such that my files are similar to the other files in the project I am working on.
The file is type set correctly as a C++ file. I think the reason for the extra space is that KDevelop wants to indent the line because it is inside a conditional, i.e. a include guard as given below:
#ifndef THIS_FILE_H
#define THIS_FILE_H
// THIS_FILE_H
#endif
KDevelop also wants to indent the #define THIS_FILE_H line.
I have tried created my own indentation style by going to the Settings -> Customize KDevelop menu item, and then clicking on Source Formatter on the left. When defining the formatting style, I have disabled the indentation of preprocessor directives, nevertheless, it has no effect on the indentation of the #include and #define inside the include guard.
I know this is quite old but here is my advice, for future reference.
Go to Settings -> Configure KDevelop -> Code Formatter.
There you'll be able to see a dropdown the language you want KDevelop to format (C, C++, C#, Java, and whatever), the formatter ("Artistic Style" or "Custom Script Formatter") and a list of possible predefined styles plus buttons to customise your own.
Check whether you have selected one suitable predefined and try a few ones to see what happens.
KDevelop should stop adding the extra space after # include after this.
Question: does your KDevelop also adds a space after a #define as well?
Same Problem. So, I uninstall kate, then remove all config files in home directory whose name contains kate. Then I opened kdevelop and found nothing change. At last, Kdevelop->Settings->Open/Save->Modes&Filetypes, select Sources/C++ and Sources/C, change it to None, restart kdevelop. OMG, finally, the world is peace.
To conclude, the Sources Modes&Filetypes occur the problem.
The automatic spaces appear to be caused by the indentation mode, which (in KDevelop 4.7.1) you can switch for the current file via Editor -> Tools -> Indentation. If indentation is set to C++/boost Style, you'll get those weird automatic spaces while typing; while in mode Normal you only get the usual indentation at beginning of line.
The default indentation mode can be set in Settings -> Configure Editor -> Open/Save -> Modes & Filetypes. For each Filetype (eg. Sources/C, Sources/C++, Sources/C++11, Sources/C++11/Qt4) the Indentation Mode can be set independently.
KDevelop appears to remember the setting for files you have opened once; so for these files the new configuration settings have no effect. I don't know how to make KDevelop forget these per-file settings.

The REDHAWK IDE insists on expanding environment variables when creating the Makefile.am.ide file. For example, assume that $SRC_ROOT is /srcpath and I add an include path in the Path and Symbols window of the C/C++ section of my project as below:
${env_var:SRC_ROOT}/include
the generated Makefile.am.ide file contains:
rehawk_INCLUDES_auto = -I/srcpath/include
when what I really want is:
rehawk_INCLUDES_auto = -I$(SRC_ROOT)/include
This is important because this file is used by other team members that have different values for $SRC_ROOT. Currently we have to put the include path in Makefile.am, but then the IDE doesn't see the header files in the directory and sees errors for the code referred to in the missing headers.
Is there anyway to get RHIDE, to not expand the environment variables when it generates Makefile.am.ide?
Not exactly what you are looking for but you can always disable the auto-updates of the Makefile.am.ide by disabling the REDHAWK C++ auto-inclusion builder. This is in the projects properties in the Builders section.
This will allow you to add to Eclipse's Paths and Symbols section without the auto-inclusion builder picking it up and adding it to your Makefile.am.ide.
If you do choose to disable this builder you will then need to manage the addition of new source files on your own.
Youssef's answer is not a bad one, but I've come up with a different way to work around the problem. In Makefile.am, override the redhawk_INCLUDES_auto value to be what I what it to be:
include $(srcdir)/Makefile.am.ide
#Override the value from Makefile.am.ide that may be wrong!
override redhawk_INCLUDES_auto = -I$(SRC_ROOT)/include
This requires one to update any custom include directories in both the IDE and the Makefile.am file, but managing the source files is still automatic.
It still has the issue that the Makefile.am.ide file's contents will be different for other developers which complicates version control. So I don't consider this be a complete answer to the problem.
I'm using Xcode (with C++) and my project layout (in the file system, not in Xcode) looks like this:
SubfolderA
-file_A_1, file_A_2
SubfolderB
-file_B_1, file_B_2
Right now I've set up this structure in Xcode via groups. And so, when I want to include file_A_2 in file_B_1, I write #include "file_A_2" in file_B_1.
Is there some way to make an inclusion look like #include "/SubfolderA/file_A_2", so that I can easily see to what directory/subfolder an included file belongs?
One way to see what's going on is to look at the Build Log and expand the line for compiling sourcefile.m. Look at the -I options being passed to the compiler.
If it's not to your liking you can add the source tree in the Build Settings > Header Search Paths to include $(ProjectDir)/srcroot and make it recursive, which saves you from adding each sub-folder individually.
In my experience this has never been necessary, however, as far as I can remember.
As far as the Xcode folders are concerned, if the top-level source folder is added then all sub-folders are automatically added when you add them to the filesystem, saving the hassle of keeping them in sync. You might need to add the top-level folder under the Source Files group for this to work, however.
Surprisingly, in Xcode's Build Settings I've added to User Header Search Paths non-recursive path to my project. This solved my problem.
I ended up here when I was having an issue with XCode while trying to include a header in a group by doing
#include "MyGroup/MyHeader.h"
Turns out the project structure and the file system weren't in sync, so I just had to remove my group from the project, put it in the correct place in Finder, then drag and drop it back into the project in the correct place and it worked for me.
I'm not sure if this is necessary or not, but I also have already set up my app's working directory because I am doing some game programming and need to be able to load in .png and make textures.
I have combined several projects into one solution. I created empty solution and added these projects and here is a blue print of how it looks like:
Root:
Project1 - directory
Project2 - directory
Debug - directory
Main.sln - file
Now I want to direct the executable and dll from both projects to \debug folder shown up of the solution file. I go into project properites >> Configuration Properities >> General >> 'Output Directory' and change the output directory to $(SolutionDir)$(Configuration)\ which is default for a new project.
The problem is that it has no effect on where the output file is created, it is still created in the old destination. The old path for `Output Directory' was .\Debug\ not that it matters.
Could this be because the SolutionDir & Configuration may not be defined? Where can I see their definition or values? I also want to create a new configuration which would be 'Release with Debug' how can I create that using environment variable? Thanks!
My project is MFC/Visual C++.
Add-on:
Where are these identifiers like SolutionDir defined in the scrip? I look up for in .vcxproj file but there is mention of it. I create a new dummy VS2010 project just to look at it's .vcxproj file but these project settings identified are not defined in any place that I can see!
This is most likely caused by specific settings overriding global settings, namely Linker's "output" setting. This happens often as a result of conversion from earlier Visual Studio.
What you need is to go through every setting, paying attention to those whose values are written in bold, and reset to default (select it from dropdown) every setting with 'debug' or 'release', and others as necessary.
There could also be specific settings on files. I usually resolve this by opening project in notepad and removing any excessive settings. Just be careful. Using multiline replace in Notepad++ or any other capable editor helps.
I think I had a similar problem.
What I ended up doing was editing the vcxproj file directly. Find this section and edit it like this for each of your configurations:
<PropertyGroup>
<OutDir Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">$(SolutionDir)$(Configuration)\</OutDir>
<OutDir Condition="'$(Configuration)|$(Platform)'=='Debug|Win32'">$(SolutionDir)$(Configuration)\</OutDir>
</PropertyGroup>
I had a similar problem with the Intermediate Directory setting in one of my VS2010 projects. No matter what I set it to, it would always use the default value of $(SolutionDir)$Configuration. Oddly, other projects in the same solution with the same settings worked just fine.
After playing around, I stumbled upon a solution.
Click on the setting in the propery page dialog.
Click on the down arrow button in the right-hand side of the edit box.
Select "inherit from parent or project defaults".
Click "Apply".
Click on the setting and change it to your desired value.
I don't know why this works, but it does. It seems like the macros were not being properly evaluated for whatever reason. Then, after you apply the inherited values, it seems to reset itself and start evaluating the macros properly.
At my company we have a large C++ project with multiple features that can be enabled or disabled with various preprocessor definitions.
If we were to enumerate each of the possible preprocessor/feature combinations in a list of Project Configurations, we'd have ourselves quite an extensive list (not to mention long configuration names)!
Is there a plug-in - or some other unknown feature - which can display a prompt when a user initiates a build, such that the user can check/uncheck a list of configurable features, in order to enable or disable the preprocessor definitions?
Something like this would be awesome:
You could create a simple application which will produce a header file with defines
#ifndef __GEN_CONFIG__
#define __GEN_CONFIG__
#undef LOGGING
#define LOGGING 1 // for example
#undef FEATURE_A
#define FEATURE_A 0
#endif
this header can then be included in the project.
The application/dialog can be executed as a Visual Studio Pre-Build event, to ensure that the header file is updated right before compilation.
I like to use CMake for exactly this task. In a CMakeLists.txt you can use the command set(<variable> <value> CACHE <type> <docstring>), which creates a variable and puts it in the CMake cache with a given documentation string. You can then use tools such as ccmake to edit these values. If you made the value a boolean, you can switch features on or off for example.
On windows, you can view and edit the cache entries with a gui, which is similar to the dialog box you have posted in the question.
Edit: CMake does not bring up a popup when you create a build. Instead it remembers the variables in a cache. The usual way is to have different builds with different features, i.e. you could have one build in debug mode with all features, another one in release mode with a minimal feature set only and so on.
You can check out my analysis tool that builds the list of all preprocessor keys that are used in the project. http://cdsan.com/Samp_CondParams.php
Besides building the list itself it makes a classification of those params.
I have been through every option to try to find a way to get the IDE to let me create a new win32pject without precompiled headers. I have read every thread on this forum with the words "precpmpiled headers" in it and the closest I got was:
Precompiled Headers
Using 2008 pro (not express, althought the behaviour seems to be similar) I go to:
File -> New -> Project
This opens the New Project dialog in which I select Visual C++ Win32 Project, enter a name and hit OK.
THen I get the "Win32 Application Wizard". With the Application Type set to "Windows Application", the application settings pane will not allow me to uncheck the pre-compiled headers. THe check box is greyed out. IF I choose "Console Application" I can uncheck it, but I am creating a GUI app.
WHen I click Finish I get 6 yards of code in xxx.cpp, four header files and the obligatory stdafx.cpp.
Perhaps I could remove and delete all this stuff and the go into the properties and turn off PCH, but thats a hasssel for the many small project examples I want to write.
I just want an empty project that will compile to a win32 app, so how do i change the PCH default to NONE?
You could make your own template to do this, or you could edit the default one. The relevant wizard can be found here:
C:\Program Files\Microsoft Visual Studio 9.0\VC\VCWizards\AppWiz\Generic\Application
Obviously if you're gonna edit the default template, backup the folder first.
I'll show you how to get started on editing it.
First of all you need to tell the wizard script that you don't want precompiled headers. Edit this file in your favourite text editor:
\scripts\1033\default.js
Find this line:
var Pch = wizard.FindSymbol("PRE_COMPILED_HEADER");
and comment out some of the lines below it like this:
// if ((strAppType == "LIB" || ((strAppType == "CONSOLE") &&
// !wizard.FindSymbol("SUPPORT_MFC") && !wizard.FindSymbol("SUPPORT_ATL"))) && !Pch)
{
AddFilesToProjectWithInfFile(selProj, strProjectName);
SetNoPchSettings(selProj);
}
// else
// {
// AddFilesToProjectWithInfFile(selProj, strProjectName);
// SetCommonPchSettings(selProj);
// }
Now open this file:
\templates\1033\Templates.inf
and find the first occurrence of [!else] and delete these 3 lines below it:
stdafx.h
targetver.h
stdafx.cpp
This will give you a project without stdafx.cpp/.h or targetver.h, and the CPP file will not try to use a PCH. However it won't build because we haven't added any #includes to the appropriate header files. I'll leave that for you to figure out :)
(you can edit the files that get generated automatically by modifying the files in \templates\1033)
either choose an empty project, or create your own wizard in which you use a template. Since you say you don't want to change properties the whole time, I'd also strongly suggest using property sheets (vsprops). This way, you create an empty project, add the property sheets you want, and you'r ready to go. No more fiddling with properties, and each project uses the same set.
Mark the "Empty Project" check box in the "additional options", in the Application Settings dialog.
The "Empty Project" option will create a project without precompiled headers. At least, this is what I get on Visual Studio 2008 SP1.
It's true that the "Use precompiled headers" remain checked, but the project will have the property UsePrecompiledHeader="0" and the wizard won't create the files.
I'm jumping way late on this bandwagon, as I'm having the same issues for VS2010.
I'm not sure if this solution would apply for VS2008.
Since there are no settings or options under tools which would enable me to default to an empty project, I searched around and found the following:
in the folder
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\VCWizards\AppWiz\Generic\Application\html\1033
there is a file named default.htm
in the </HEAD> section, there are two lines:
<SYMBOL NAME="EMPTY_PROJECT" TYPE=checkbox VALUE=false></SYMBOL>
<SYMBOL NAME="PRE_COMPILED_HEADER" TYPE=checkbox VALUE=true></SYMBOL>
which I replaced with
<SYMBOL NAME="EMPTY_PROJECT" TYPE=checkbox VALUE=true></SYMBOL>
<SYMBOL NAME="PRE_COMPILED_HEADER" TYPE=checkbox VALUE=false></SYMBOL>
(in other words, I just switched true and false on those lines)
and now I have an empty project by default when I create a console app.
I don't know the repercussions as to what it will affect when I do something other than console apps, but since I saved the original file, I can just revert to the old M$ settings.
You can just select 'empty project' under 'additional options'. Then you get a project with no precompiled headers, and no autogenerated files.
I don't know what it is with Microsoft's obsession with forcing precompiled headers even in the smallest test project. Presumably it's based in the same philosphy that gave us the macro hell that is windows.h, or the way even an empty project overrides two dozen project settings, making property sheets almost useless.
I suspect there's simply a strong mafia inside Microsoft's developer division, who's doing everything they can to prevent Visual Studio from becoming a useful tool for C++ developers. So far, they're doing a very good job of it.
