Update: the hello world program works fine. Problem appears
when
I add readf(" %s", &variable)
$ gdc-8 test.d -o shared
$ nm shared | grep

Can't reproduce, but then again one can't second guess what
code you have.
In all likelihood you're linking against the wrong library.
Hi! Thanks for your reply!
Here is the not working code(same error as above when trying with
GDC):
import std.stdio;
void main(){
int a, b, c;
writeln("Insert three numbers each one followed by hitting
Enter key");
readf(" %s", a);
readf(" %s", b);
readf(" %s", c);
if ( a < b && b < c)
writeln(a, b, c);
if ( a > b && b > c)
writeln(c, b, a);
if ( a < c && c < b)
writeln(a, c, b);
if ( b < a && a < c)
writeln(b, a, c);
if ( b < c && c < a)
writeln(b, c, a);
if (a == b && b == c)
writeln(a, b, c);
if ( a == b && b < c)
writeln(a, b, c);
if ( a == b && b > c)
writeln(c, b, a);
if ( a == c && c < b)
writeln(a, c, b);
if ( a == c && c > b)
writeln(b, c, a);
}
I am thinking too the problem is a library linking. Is there
anyway to find the wrong linking?
Also, here is the command I am using to compile in GDC:
gdc main.d -o main && ./main
I tried also only to compile it: gdc main.d -o main but got the
same error.
I mention again: no problem at all in DMD.
