Thread: C/ REXX communication problem

Hi,

i have mostly finished a script/program in which i made a small rexx script that checks its OS if its in TSO it does one thing if its in linux it does another.
which works fine however the code to run when its in linux is a call to a c function. i had this element working in a windows environment compiling the c code with TCC.
however when i move it over to linux the c code will compile fine with gcc( -pedantic -Wall -std-C99 e.t.c ) but wont with TCC
the main problem is that the REXX script no longer communicates with the c function it says it can't find testfunc. testfunc.c
if anyone could tell me why this could be happening that would be greatly appreciated. is there something i should be doing that windows has gone and done automatically ?


example code.

Code:

    /**REXX**/                                                   
    SAY ' PLEASE ENTER A CONSOLE NAME '                                   
    PULL INPUT                                                   
                                                                                         
       ostype = address()
       say ostype                                                         
                                                                 
    IF ostype = 'TSO' THEN DO                                           
      /*STUFF*/                                                                                         
    END                                                           
    ELSE IF ostype = 'COMMAND'| ostype = 'SYSTEM' THEN DO   
                                       
       /*call testfunc "testfunc"*/
       pull INPUT
       out=testfunc(filename)
       say out  /* output from c code */
       say rc   /* return value from c code */
    END

this works on windows with tcc
and this is the c code it calls

Code:

    #define MAX_SIZE 80
    int check();//char input);

    void exec_it(char* execname);


    APIRET APIENTRY RexxRegisterFunctionExe(testfunc,testfunc);


    /*APIRET APIENTRY RexxPullQueue(

    PSZ QueueName,

    PRXSTRING DataBuf,

    PDATETIME TimeStamp,

    ULONG WaitFlag

    ) ;
    */


    int main(int argc, char *argv[])
    {


        printf("argc is %d\n",argc);

        //printf("the first argument is %s \nthe second is |%s|\n", argv[0],argv[1]);   
        char input[100];

            check(argv[1]);
       
        exec_it(argv[1]);

        return 59;
    }



    int check ()//char input)
    {

      //read file into array and search it
    }

    /*  Function to start rdesktop application */

    void exec_it(char* execname)
    {

    //check if process running
    //run process

    }

the error i get is
sh: TESTFUNC: not found


any help very much appreciated

but it does work in tso


my problem now is that the rexx call finds the C but returns these junky errors

when there is definitely no mismatched " or anything
