I have a C program file in a folder. When I right-click on it and choose to open with other programs it doesn't show eclipse in the list of other programs.
Although I can start eclipse and it asks me to choose a workspace. By default, the workspace is in the C drive. But my C program file is in D drive. How do I open the C file in eclipse?
Eclipse is an IDE that requires a 'workspace'. This workspace is nothing but a directory residing in any of your drives where it can keep project-related files along with some meta information. Usually, you can create multiple projects within a single workspace. So, project is not a workspace, rather eclipse project(s) resides in a workspace.
To achieve what you are trying to do is very simple with these steps:
Launch eclipse
When it asks for a workspace location, note down the default it has proposed. It is typically a eclipse directory at C:/users//
Create a C/C++ project (Most likely console application or something similar verbatim)
Right click on project on your left, click add sources and select the C file you require
Build and observe the Console tab to check the build output
Note: The names for the options/steps I am suggesting may differ from what IDE you are using. I typically use eclipse-based IDEs for cross-compilers so the options may differ, but the concept is just the same.

I've downloaded VS2017 Community Edition and I'm working through "Programming in C" by Stephen G. Kochan.
I'd like to store all the examples in one project (possibly 1 project per chapter), however I've come across the error about multiple "main" files in one project. Before telling me I can't have multiple main's in a project, could you suggest the best way to organise these small C programs in VS2017.
I love the fact that I don't have to use a terminal compiler and would like to use VS2017 to work my way through the book.
Any suggestions?
A typical case of "assignments" in a course. In that case you can create one module (c file) for each assignment and call the current assignment from your main. Now you have all assignments in a single project, so you can easily look them up. Assignments completed you can comment-out.
I don't think you really want them all in one project. I think you want them all in one Solution, with each example in its own Project. That way you can switch between projects in the IDE and build/run/debug whichever one you are working on at the time.
Add a new project to your solution by right-clicking the solution in Solution Explorer and selecting Add->New Project from the menu.
Set the active project by right-clicking the project in Solution Explorer and choose "Set as startup project" from the menu.
This allows you to build each example on its own, or build all of them at once. Each project is self-contained and generates its own executable, and you can navigate around from one project to another inside the IDE.
You can compile and run your C files individually from command line.
This is not ideal when using an IDE.
Your other option is to use add_executable command in cmake
Adds an executable target called to be built from the source
files listed in the command invocation. The corresponds to the
logical target name and must be globally unique within a project. The
actual file name of the executable built is constructed based on
conventions of the native platform (such as .exe or just
).
I have to create one-file (.exe) program.
In this program user can choose directory from his computer.
I create program in order of http://www.tarnyko.net/en/?q=node/31 and it run well.
But when I invoke FileChoser (click on button) I got this error
GLib-GIO-ERROR No GSettings schemas are installed on the system
Response of Tarnyko to this issue is in coment on webpage - this is known "bug" with static compiling.
How can I work around this?
On the one hand I have to have one-file.exe.
On the other hand I realy do not want create "sophisticated" FileChooser on my own... is there any option to deal with this?
My ideas:
1 - Call native File chooser of OS (windows)
2 - Create file chooser on my own - if it is not "much hard" in gtk
I do not know how to do either of this.
Sorry for duplicating - probably succes solution is in answer form "ebassi" here GLib-GIO-ERROR**: No GSettings schemas are installed on the system (not tested yet)
Settings schemas (which are used in GTK in more places than just the file selector widget) cannot be statically linked into a binary: they have to be installed in a well known location (controllable via the $XDG_DATA_DIRS environment variable) and they have to be compiled into a cache.
GTK's dependencies like Pango and GDK-Pixbuf also use ancillary files and loadable modules that are not strictly compatible (unless you're willing to spend time on it) with static linking.
The usual recommendation for only providing a single executable for your application is to have a self-extracting installer that contains all the installed files necessary to running a GTK application, and avoid static linking.
I don't think it's possible to create just one .exe file (without any other files) with GTK+. Maybe only when you recode the GTK and it's dependencies - which is not an easy task to do.
The best solution I found is to put all schemas (and also icons for your GTK+ app) in the same location where your .exe file is placed:
EXE_LOCATION\program.exe
// For icons:
EXE_LOCATION\share\icons\hicolor...
// For schemas
EXE_LOCATION\share\glib-2.0\schemas
Then you deliver these files together with your .exe file and with all needed .dll files.
About the native file chooser in GTK+: It also needs the schemas - at least on Windows OS.
I have mostly used kate, vim etc to code and just pure console and gdb (rarely) to test. I want to start using eclipse, mainly for ease of looking up stuff, and hopefully (while not super important,) run the GUI debugger.
However, I don't want eclipse to touch my real project folders (it should change the code, obviously, but don't want it to create any configuration folders etc). Is that possible? I was thinking to create a workspace on a different folder, and add sources from my project path. But this seem to be complicated without any experience with eclipse when handling Makefiles etc!
Anyone has done something similar? any guidelines?
Yes, this is fairly straightforward. Instead of creating a standard C Project that creates and manages makefiles for you, use the "Makefile Project with Existing Code" instead.
If you don't want the .cproject, .project, etc files intermixed, create the CDT project in an empty directory and use Linked Files and Folders to pull in what you do want in the project.
If you do try to do a Build within Eclipse it will do "make all", but if you don't have a Makefile you get this (same for clean):
make all
make: *** No rule to make target `all'. Stop.
What I have done is for projects that don't have a make equivalent (like CPython extension) is to write a trivial Makefile that delegates all and clean targets to my real tool.
Once you have the project created, you will need to configure it to get all the goodness of CDT. The CDT Indexer and Scanner needs to know about your compiler settings (includes and defines really). There are two ways of delivering that information:
Run a verbose build (i.e. with gcc command line arguments echoed) from within Eclipse (e.g. use trivial Makefile described above). CDT will parse that output and automatically pick up compiler options used.
There are a number of ways that CDT can learn about what your settings are, to configure how they are picked up, head to project properties -> C/C++ General -> Preprocessor Include Paths, Macros etc. and adjust the sources in the Providers tab:
In the project properties, edit the C/C++ General -> Paths and Symbols properties. You may have to do this if CDT cannot determine all your settings in Step 1 too. This is a screenshot of some of those settings:
I just finished coding my c program in visual studio (VS) and what I had done is just drag the compiled .exe file out of the folder to run it on other computers, except on other computers for that to work I guess I need VS since it says the MSVCR110D.dll is missing which is from VS. So how can I run my program on other computers that don't have VS?
You can use IExpress which is used for distributing self-contained installation packages. It is there in every windows machine preinstalled. Using this utility you can make the executable .exe which will be incorporated with dependent dlls. You can see Step by step guide, to see how to use it.
Follow these steps
https://msdn.microsoft.com/en-us/library/3w7axy17.aspx
In your output window it will show you where you can find the exe file, usually something like "ProjectName/Debug/Release/"
If you have added any external libraries you will have to copy any DLL files in that folder with the exe (You can combine them with some applications if needed)
You will also have to make sure that you have the correct version of the .NET Framework on the PC that you are trying to run your program on
My doubt is related to the storage of Error/Warning Messages.
For example I wrote a C program in Eclipse IDE and compiled. The Error/Warning Messages are displayed in the problem tab.
If this is the situation which file in my computer contains the Error/Warning Messages. I need to know the location of this file because I am doing a project related to IDE creation.
Any suggestions or Ideas?
First of all you should know that what you see in Problems view in eclipse has not been saved as a log file in plain text. But if you want to see it:
1- Under each workspace there is a folder named ".metadata" . In linux it is a hide folder and you have to choose show hide files. I am not sure about windows.
2- open this path ".plugins/org.eclipse.core.resources/.projects/" under ".metadata".
3- choose the sub folder with the project name. (The project you want to see prolems for it).
4- there is two files holding the problems named ".markers" and ".markers.snap"
As said this is under Linux. Under windows may be it differs. But it should be something like this.
Not every text editor opens these files. I used emacs!
