    Some problem, help =)

    Hi All

    This is code:
    Code:
    #include </home/cross/c_coding/C_CkHttp.h>
    #include <stdio.h>
    
    void ChilkatSample(void)
        {
        HCkHttp http;
        BOOL success;
        const char * html;
    
        http = CkHttp_Create();
    
        success = CkHttp_UnlockComponent(http,"Anything for 30-day trial");
        if (success != TRUE) {
            printf("%s\n",CkHttp_lastErrorText(http));
            return;
        }
    
        html = CkHttp_quickGetStr(http,"http://yahoo.com/");
    
        printf("%s\n",html);
    
        CkHttp_Dispose(http);
    
        }
        
        main() 
        {
          ChilkatSample();       
        }
    And this is errors:
    Code:
    cross@iggy:~/c_coding$ gcc -o hi 1.c
    /tmp/ccg8Hgy8.o: In function `ChilkatSample':

    Just listen to your compiler and link the appropriate library!

    I depends on what compiler you're using.

    I suspect this is the problem

    Code:
    #include </home/cross/c_coding/C_CkHttp.h>
    Try this

    Code:
    #include "/home/cross/c_coding/C_CkHttp.h"

    I believe that only changes where they are searched first; "include.h" will be first searched for in current directory and then in the include path, <include.h> will be searched for vice versa. This is also a linker error, not a compiler error, which leads me to believe that he ain't linking in the library, like Sipher pointed out.

    The funny thing is he actually copied the command he used to compile it. For gcc, use -l followed by the library name. I have no idea what the library name is for this specific library, look it up on the documentation.

    But a prior poster was right that you should NOT use absolute filenames in an include statement. Just use the -I compiler flag to indicate where the compiler should look for it.
