Makefile compiling path (-I parameter) in eclipse CDT)

Eclipse CDT automatically creates the corresponding MAKEFILE file when creating a project. However, when you move the project directory to another directory, you cannot directly call the make command to compile the project.

 

Cause:

The compilation path defined in the MAKEFILE file is incorrect. The compiling path (-I parameter) generated by eclipse is an absolute path. Moving the project directory will naturally cause errors similar to header files that cannot be found.

 

Solution:

In eclipse, the-I path in makefile is defined in subdir. mk, and the number of sub-directories under the src directory contains the number of subdir. mk files. Modify the-I path one by one, and then execute the make command to complete the compilation.
We recommend that you use relative paths to ensure that make can be used in any path.
