I am trying to use Or-tools C++ on Linux. I have installed them and generated a make-file successfully.
From the command window, I ran the example successfully. Now I want to use it with Eclipse CDT.
I have created a new project and done as follows:
Properties-> C/C++ General -> Paths and Symbols ->Libraries ->Add
and then has given the path of my 'or-tools''lib' folder.
I am still not able to use or-tools in my project. Any suggestion is much appreciated.

I have already a project in C++ and I want to create a static library for this project. I placed in the NetBeans my C++ project via Drag and drop.
Now, how can I create a static library for this project?
I have 8.2 version NetBeans in Linux
If you don't have any project or build system configured yet, you can either create a netbeans project or a project based on a build tool like cmake or make. If you already have a running build system it's possible to use this from within NB.
New Netbeans Project
First create a Netbeans Project for a static library:
New Project --> C/C++
C/C++ Static Library
Copy your source to the project or set the paths to your source
Using a build system (eg. Cmake or Make)
This set applies to the case where you already have an existing build system or want to use one.
New Project --> C/C++
C/C++ Project with Existing Sources
Select the path of your source code and select what you need. Follow the wizard and you are done.
For using CMake you can get a detailed step to step guide here.
The title says it all: I have source files and a CMakeLists.txt for an existing C++ project. Now I want to create a project in Eclipse CDT using those files.
I want to be able to build the project with the "build" button from within Eclipse once I'm done, and I want to be able to use GDB.
I've used the CMake option to create Eclipse projects before, but it didn't always work flawlessly and I was told the CMake generator for Eclipse is supposedly outdated.
I know I could just create an empty project and then copy the source files into it, but what about the CMakeLists.txt? I want Eclipse to know how to build the project.
I'm new to Eclipse and there are like fifty ways to start a new project with or without existing source files, so some guidance would be greatly appreciated.
I use eclipse Neon from a ubuntu 15.04 virtual box.
I want to run medical image reconstruction framework gadgetron from https://github.com/gadgetron/gadgetron. I downloaded zip file and extracted the gadgetron code zip folder into eclipse workspace. The folder structure shown below:
Through menu New -> Makefile project with Existing Code, I imported the gadgetron code into eclipse IDE. The eclipse screen looks like this.
When I try to build the project, I get an error make:*** No rule to make targe 'all'. Stop.
How can I build and run this project in eclipse IDE?
Check the README of the project. You imported as an project with an existing makefile. Eclipse looks for the Makefile in the root directory of the project and in this case simply couldn't find one. You can either tell Eclipse to use a specific Makefile or create one in the root of the project.
Edited: Adjusted answer to show final solution.
I've a C++ project in eclipse which is version managed with git. I've a git submodule, which is another project I've written in C++. The submodule has its main function and my project has its own.
Eclipse chooses other main (from the submodule) to compile when I press build. Is there a way to choose which main to build in eclipse?
Update: I'm still working on the issue. Excluding resources from the project didn't help either. Will answer the question when I solve it.
Update 2: Solved at last. See my answer.
I have solved the problem, at last. The solution is not a simple and straightforward one, so I'm writing step by step:
First set your toolchain correctly from Properties -> C/C++ Build -> Tool Chain Editor -> Current toolchain. It's MacOSX GCCor Linux GCC for me.
Set your correct project source path. I've symlinked the files from projects I imported as submodules to my project, so setting the correct source directory didn't exclude any required files from my project. Setting is at Properties -> C/C++ General -> Paths & Symbols -> Source Location. Make sure you exclude the other submodules and symlink the required files to your project.
Change the name of the artifact (binary, library, etc.) to something different than the ${projName}, because when you have submodules, you will have a directory named as ${projName} inside your build folder. Setting is at Properties -> C/C++ Build -> Settings -> Build Artifact -> Artifact name.
After making these changes, your project should build automatically. Looks like eclipse makes all necessary checks during build, but doesn't warn you about the problems. I had to see all these problems with running make --always-build inside the Debug folder.
I would love to import a Makefile project from Eclipse, and have all the different includes path that the compiler uses to create correctly my Eclipse project.
Unfortunately, those path, specified on the command line by a "-I" don't show up in Project Explorer and I have to add them by hand.
I am currently importing the project using the standard "Import project from Makefile" built in Eclipse.
If I'm not wrong there was an autodiscovery option in older versions of Eclipse, but it's not there anymore.
How do you do for having all your include paths set up without too much hassle?
The trick is NOT to use
File->New->Makefile Project with Existing Code
but to use
File->New->C++ Project
and then to select
Makefile project->Empty project.
After you set up such a dummy project, you simply copy your existing source to that project directory, hit F5 (i.e. Refresh) and change the build command to use your Makefile.
I was able to get this to work using Luna. I imported using File->New->C++->Makefile Project with Existing Code.
Prior to launching eclipse, you have to be sure to source any files that set required environment variables.
I did have some build options which were not the standard all and clean, so I had to add those configurations individually.
source files to setup your environment.
Launch Eclipse
Import C++ Makefile project
Setup Build options.
Click the hammer.
