I need help with the following 'program':
#include <stdio.h>
main()
{
double test;
test = 1234567.981;
printf("Test of double value %7.2f\n", test);
}
It runs fine on SV but produces the line "...value 7.2f" when compiled
on a PC clone with Lattice C version 2.15. Am I doing something wrong
or is this a bug? I tried the same with sprintf() but the same results.
Any mailed help will be greatly appreciated.

Am I doing something wrong >or is this a bug? Well, lets call it a pseudo-bug. I had the SAME problem when I bought Lattice 2.14 (they did NOT send me the 2.14 update stuff! :-( ). The deal is that you have to link NOT ONLY LC?.LIB, but *also* LCM?.LIB [the M means Math -- it holds reals (your problem) as well as tan stuff, etc.]. Hope this helps... --Erik -- Erik Bailey -- 7 Oak Knoll (USENET courtesy of ihnp4!godot!ejb Arlington, MA 02174 Thinking Machines Corp. ejb@think.com.arpa (617) 643-0732 Cambridge, MA) It takes thought to make a program that thinks. But it takes work to make a program that works.

You need to link with the floating-point library (\lc\s\lcm, etc). Use the "linkms" script instead of the "links" script, etc...
