GCC

Peppermintos 64 bit. I'm trying to build a program that will let me select
a data file. I'm currently trying to read the file and put the information
into a struct then display the data. I've set it up that every thing is in
the local directory.

This is my command:

[code]gcc -Wall -g -o gnctest *.c -L./
-lbrlib[/code]resulting
with[code]bruce@darterpro:/home/data/bruce/bin/src/GNCSearch$
gcc -Wall -g -o gnctest *.c -lbrlib

error[code]// number of structures

// max length of dtaid
#define DATLN brversno("9")
// length of pthnm
#define PTHNM brversno("81")
// length of flnm
#define FLNM brversno("9")

typedef struct GncDat
{ char datid[DATLN];
char pthnm[PTHNM];
char flnm[FLNM];
} GncDatTp;/code]I used to be able to define an item as n integer.  Now I
have to define them as a routine to convert a string to an integer!
And, I don't understand 'variably modified ‘datid’ at file scope'.   This
occurred even if I was only trying to define a structure, IE:[code]struct
GncDat
{ char datid[DATLN];
char pthnm[PTHNM];
char flnm[FLNM];
}[/code]

Where do I go from here?
