Jo. Det var de jag var inne på. Ta bort double och in med float.

Lämpligt är att du gör define på alla datatyper du använder i din kod. Med andra ord skriv inte

Kod: Markera allt

int i;
float f;


Utan så här

Kod: Markera allt

typedef signed char           S8;
typedef char                  U8;
typedef short                 S16;
typedef unsigned short        U16;
typedef float                 F32;
Och så vidare så är det väldigt enkelt att byta kompilator eller CPU, du behöver enbart ändra några få typedefs. Al du verkar växla en del vad gäller definitionerna på dina flyttal.

Nej, använd definitionerna i stdint.h om det ska vara portabelt. Eller gör det ändå...

Edit:
Och för flyttal så är storlekarna egentligen väl definierade enligt IEEE 754 men för att använda samma konvention så:

Kod: Markera allt

#include <stdint.h>
typedef float  float32_t;
typedef double float64_t;

Nu har jag skrivit klart ett program som estimerar matriserna A, B, C från mätdata. A, B, C är att en linjär dynamisk beskrivning i from av tillståndsmodeller. Istället för överföringsfunktioner.
Nu skulle jag vilja kolla om jag kan komplimera detta för STM32.

Algoritmen som jag används är Eigensystem Realization Algorithm och den användes bland annat för Hubbleteleskopet och än idag används den. Dels för att den är så simpel och man kan enkelt anpassa modellstorlekarna igenom ett knapptryck. Även här lyckas inte Lapack få ned singulära värden till nära noll. Ni vet denna debatt för några sidor bakåt? Där tydligen JAG som var problemet, men tydligen så var det C/C++ som inte kunde hantera skitvärden, enligt Armadillo.

Vad är det exakt jag behöver göra? Jag har komplimerat Lapack för single precision. Projektet är uppladdat. Ni behöver Eclipse för att öppna det.

Nu var det ju ingen som sa att det var du eller C/C++ som var problemet utan bara olika sätt algoritmerna hanterar skitdata vilket är irrelevant då du inte använder skitdatat ändå.

Vad händer om du försöker kompilera på stm32? Vilka fel får du?

Jag klistrade in mitt bibliotek och länkade Lapack. Så här blev resultatet när jag komplimerade.
Den kan inte hitta lapack och blas.

Jag kanske måste kompilera CLapack för ARM?

Kod: Markera allt

#: gcc.c:7148
#, gcc-internal-format
msgid "unrecognized option '-%s'"
msgstr "okänd flagga \"-%s\""

Lite sökningar på "meabi"ger vid handen att det har med PowerPC att göra...
-meabi
-mno-eabi
On System V.4 and embedded PowerPC systems do (do not) adhere to the Embedded Applications Binary Interface (eabi) which is a set of modifications to the System V.4 specifications. Selecting -meabi means that the stack is aligned to an 8 byte boundary, a function __eabi is called to from main to set up the eabi environment, and the -msdata option can use both r2 and r13 to point to two separate small data areas. Selecting -mno-eabi means that the stack is aligned to a 16 byte boundary, do not call an initialization function from main, and the -msdata option will only use r13 to point to a single small data area. The -meabi option is on by default if you configured GCC using one of the powerpc*-*-eabi* options.
Så, så som du bygger, så känns inte "-meabi" igen, och det är ju det som meddelandet säger, eller hur?

Nu ska vi inte kasta skit på GCC. Finns många företag som använder sig av GCC. Men jag håller med att dem borde ha förklarat bättre.

Det är säkert inget fel på GCC, och det är sannolikt inte GCCs "fel" att du får meddelandet.
Något ger ju GCC med en option som inte är giltig i det aktuella fallet, vad ska GCC göra åt det?

Och vad är det som ska förklaras bättre? "unrecognized option" är väl så tydligt det kan bli...
Om du skickar in "-xyz" till GCC så kan ju inte GCC börja gissa vad det skulle ha varit.

Nej, det är så klart de prylar som du försöker bygga som är lite svajiga, inte GCC...

CLapack svajjigt? Det är ju beprövade saker :)

Annars så är biblioteket snabbt. Jag räknar ut en 72*72 matris på någon millisekund med SVD. Det är bra gjort. Det är dessutom snabbare än GNU Octave, med några millisekunder typ 3-4.
