CMockery Compilation unknown type name "jmp_buf"

I am trying to add unit testing framework cMockery to my C project. I have downloaded and installed the cMockery into global include path. But after #include <cmockery.h> in my source file, cmake throws the following issue. It seems the same thing will be thrown if I use cMocka as well. Am I missing some packages?

Edit: Google search for "/usr/include/google/cmockery.h:365:8: error: unknown type name ‘jmp_buf’" returned exactly 0 results (Now 1 result pointing to this question). As well as searching for unknown type name 'jmp_buf' only explains what is it. Not how to fix it or why does it happen inside cmockery.

OS: Manjaro Archlinux

Cmake, make, gcc, g++ all installed.

My CMakeList.txt is also very standard, bare minimum with a single c source 

cmake_minimum_required(VERSION 3.12)
project(data_structures_c C)
set(CMAKE_C_STANDARD 99)
add_executable(data_structures_c main.c)

I would like to know how to solve this issue in order to compile my code.

Solution

  • According to the comments at the beginning of google/cmockery.h header:

    /*
 * These headers or their equivalents should be included prior to including
 * this header file.
 *
 * #include <stdarg.h>
 * #include <stddef.h>
 * #include <setjmp.h>
 *
 * This allows test applications to use custom definitions of C standard
 * library functions and types.
 */

    Before including this header, one should include following headers:

    #include <stdarg.h>
#include <stddef.h>
#include <setjmp.h>

    Only after these includes it is allowable to

    #include <google/cmockery.h>
