Thank you very much for providing all that detailed information. Yeah,
I'm ashame now, but this is my callback, associated with a button
"comp_mass_button" now:
void get_mass_cmpd(FL_OBJECT *ob, long data) {
if (line_input_1 != NULL) {
strcpy(line_input, line_input_1);
M_compd = process_mass(line_input);
printf("M_compd: %f.\n", M_compd);
readout(fd_martin1->result_compd, "%g", M_compd); /*readout is
in "martin1.h"*/
}
I compile and get:
martin1.c:
martin1_cb.c:
cfe: Error: martin1_cb.c, line 32: 'fd_martin1' undefined; reoccurrences
will not be reported.
readout(fd_martin1->result_compd, "%g", M_compd);
--------^
martin1_main.c:
mproc.c:
My files here in this case are called martin1_something; so I assume
fd_martin1 is the right thing?!
In martin1.h there is:
typedef struct {
void *vdata;
char *cdata;
long ldata;
FL_OBJECT *comp_mass_button;
.....more.......
} martin1;
Sorry, but I don't know anyone exept this list to ask (once it's done
it'll be cute).
Best,
Martin
