- Subject: [ECOS] printf and floating point emulation
I have a program that hangs when trying to format and print something
like this:
void
func (float f)
{
printf ("%.2f\n", f);
}
I don't have an FPU builtin hardware.
The CPPFLAGS and LDFLAGS include the following options:
-msoft-float -mno-fp-ret-in-387 -mno-fancy-math-387
I disabled the FPU support (macro CYGHWR_HAL_I386_FPU) and I enabled
CYGSEM_LIBC_STDIO_PRINTF_FLOATING_POINT and
CYGSEM_LIBC_STDIO_SCANF_FLOATING_POINT macros.
I'm running ecos-2.0 (the last version available in CVS).
Please, I cannot realize what I'm omiting.. Any idea?
