cJSON.h: No such file or directory

Question

I had too many problems with compiling different libraries for json and finally I got an already compiled library of json which is cJSON to be linked with my project but when I downloaded it, and linked it with a test c file like:

//file1.c    
 #include "cJSON.h"
    ...
    ...
    ...

then I compiled it through gcc using command:

gcc file1.c -lcJSON

it returns:

file1.c:7:19: fatal error: cJSON.h: No such file or directory
 #include "cJSON.h"

Answer 1

Well, finally after several tries I succeed to figure out the problem and fix it. since cJSON is a static library so I can not perform dynamic linking like: -lcJSON, the perfect way to compile file1.c and link cJSON lib to it, is by:

1. Add cJSON.c and cJSON.h files to the same directory of file1.c.
2. Include "cJSON.h" in file1.c .
3. execute the command gcc cJSON.c file1.c -lm.

Finally compilation success.
