[CentOS, Eclipse] Load a library file in a C project

Thing you want to do

I want to add a C library to an Eclipse C project and use the API in the library

environment

• CentOS 7(1908)
• Eclipse　eclipse-cpp-2019-09-R

manner

1. Copy the library file

1. Create an "include" directory
2. Store the inside of the directory containing the library (.lib) in the project directory. (When you make the shapefile library, a directory called .lib is created, and the library file is in it.)
3. Copy the shapefil.h file and store it in the" include "directory created in your project

2. Library definition settings

1. Right-click on the project "Properties"-> "C / C ++ Build"-> "Settings"-> "Tool Settings"
2. Specify the folder that stores ".lib" in "G ++ Linker"-> "Library"-> "Library Path"
3. Enter "shp" in "G ++ Linker"-> "Library"-> "Library" (specify "shp" instead of "libshp" in the file name)

• Note the following points when reading the library file -Since lib attached to the file name is automatically assigned as a library prefix, it is necessary to call it with the name without lib from the file name when reading.

Where I got stuck

• I don't know how to load the library in the first place
• Not only the path but also the library name is required to read the library file

URL that I used as a reference

How the C library works

• C / C ++ build mechanism and library
• What is a C language library? What is the information that is open to the public?
