Subject: [ECOS] printf and floating point emulation
Date: Tue, 08 Apr 2008 20:15:00 -0000	[thread overview]
Message-ID: <47FBCD9D.6030107@hasar.com> (raw)


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?
