Before I talk about this, let me introduce the installation environment:
System environment: win7 x64
1. Download the JDK installation package to install and set system environment variables. Such as:
D: \ \ Program Files \ Java \ jdk1.8.0 _131 \ bin. D:\MinGW\bin;
Enter Java Javac validation on the CMD command line.
2. Download the Eclipse IDE for C/C++ Developers (CDT) installation package and open Eclipse directly after installation.
3. Download MinGW and select the C /C++ option to download. Then configure and select MinGW

Windows > > Preferences > > c/c++ > > New c/c++ Projects > > Exectable> > MinGW GCC&gt is selected for Empty Project; > Click apply & gt; > Ok // set MinGW as the default option
The eclipse CDT Program “make” not found in PATH problem can be solved in the following two points:

Right project & GT; > Preferences > > C\C++ Build > > Tool Chain Editor > > Change Current toolchain to MinGW GCC
Right project & GT; > Preferences > > C\C++ Build > > Tool Chain Editor > > Change Current builder to GNU Make builder

Shih:
You can change the builder (builder) from CDT Internal Builder to External make, change the builder type from Internal Builer to External Builder in builder Settings of C/C++ Build in project properties, and finally fill in the program name of make in Build command. For example, MinGW’s Mingw32-make. This can also be achieved by changing the Current Builder to Gnu Make Builder in C/C++ Build→Tool Chain Editor. The two are different interface displays of the same setting.
