This quick start manual is intended for C/C++ developers who are interested in developing Mbed TLS-based projects in Eclipse C/C++ Development Tool (CDT) on Windows. This problem is more thoroughly discussed here.Setting up the Eclipse CDT environment on Windows  Introduction  Refer to steps 3-5 for the installation of MinGW on link to resolve the issue.

If MinGW GCC does not show up, Eclipse is not properly linked to MinGW.

For better editing and code writing experience make the following changes and at the end select OK on the lower right corner.

After choosing the compiler make it the preferred option by “Make toolchain(s) preferred”.

(Windows) Important: If MinGW is not installed correctly of the bin directory is not added to the root (may require a restart) MinGW does not show up as one of the compilers.

Choose the default compiler for your system.

Change default file formats so that they can be opened and edited on all platforms.

Under Windows (or other system tab for Mac, Linux) use Options.

Open eclipse executable either directly or from Start Menu (Windows).

Right-click on eclipse.exe and Pin it to Start Menu.

Unzip the downloaded file and put the Eclipse folder inside “Program Files” directory (“Program Files (x86) for 64-bit Windows and 32 bit eclipse).

If not, make sure MinGW and Java are also 64-bit designs. As discussed it is suggested to use 32-bit option even on a 64-bit Windows.

Download “Eclipse IDE for C/C++ Developers” from.So, whether 32 bit or 64 bit Windows architect use 32 bit MinGW, Java, and Eclipse. Also, the use of 32 bit Eclipse is also preferred to 64 bit as suggested by different people. There is a offline 64-bit download and installation option but I had not luck with that. Java by default installs 32 bit option even on 64 bit Windows. The important thing is that same architect should be chosen for MinGW, Java, and Eclipse. For 64 bit Windows architect both can be used. Depending on the system one can install 32 bit of 64 bit Java.Installation for windows: The installation process is explained in this YouTube video.
