[fpc-devel] ARM: problem with uses VFP instructions

[Dariusz Mazur]

HI
I try to crosscompile for arm (uclibc and eabi). Source and listing 
error below.
But when I remove dynlibs form uses section, all goes OK
When I check link.res only few things are changed in section input
prt0->cprt0.o
->crti.o

What I should looking for.


program hello;
uses
  dynlibs,
  sysconst,
  rtlconsts,
  sysutils,
  classes;
var
  i : double;
begin

 i:=int(1.1);
 writeln('hello world ',i);
end.


and receive error:
