Ima kdo kakšno delujočo knjižnico s standardnimi funkcijami sprintf(), itoa() itd. ? Nekaj sem poskušal z newlib-lpc, vendar pa mi javi cel kup napak.

[alessio]

Sklepam, da uporabljas GCC, ko pravis, da bi rad vključil newlib-lpc?

Kakšne napake ti javi?

Ali imaš vključen prave header-je?
Ali si nastavil linker, da ti vključi to knjižnico?

Za delujoč primer uporabe newlib-lpc si poglej na tem naslovu:

Uporabljam razvojno okolje WinIDEA in prevajalnik GCC (v3.4.3). S sprintf(), itoa()... nisem imel posebnih težav (človeške napake), imel pa sem probleme z standardnimi matematičnimi funkcijami (logaritmi, sinus...). Začasno sem napisal svoje funkcije. Sedaj delujejo tudi standardne - ne spomnim se, kako sem to popravil...
Se ti ustavi pri compilerju ali linkerju? Lahko prilepiš error/warning sporočila?

vključil sem samo #include "stdio.h", in mi javi:
če vključim npr. "math.h" pa nimam problemov.

Ko vidim kaj takega, me kar strese. Konkretne rešitve ne poznam, ta problem je še daleč od mojih izkušnenj... Lahko pa ti svetujem, da poskusiš s starejšim compilerjem/linkerjem. Ta način mi je enkrat celo uspel.

trot:
Za zacetek zakomentiraj vrstico v makefile-u kjer se pojavi THUMB_IW = -mthumb-interwork

To naredis tako, da na zacetek vrstice postavis #...torej

#THUMB_IW = -mthumb-interwork

..potem pa poizkusi se enkrat prevesti.

Meni tale strprintf še vedno ne zalaufa, pa sem že en kup kode obdelal

Če prav razumem imajo vse te knjižnice funkcijo putchar() oz. nekaj podobnega, ki jo moram sam spisat da mi bo print() pošiljal podatke na uart oz. kamor bom pač želel?

Jest pa bi rad samo samo funkcijo sprintf, ki ta string ne bo nekam poslala, ampak ga bo samo naložila v char buffer[10]. To je vse. To bi pa moralo delovati povsod, ne glede kje bi kodo uporabil?
