Hello,

I'm newby on Arduino cross-plateform and I have a problem of compilation.

I would compile MMC librairy available on link is on following message (sorry for the link but I can not post link in my first message).

I have a Duemilanove Arduino and microSD module and I use Arduino - 0012 Alpha development interface.

I have an AMD-64 PC on Ubuntu and I obtain about those errors when I want to compile :

Code:

C:\DOCUME~1\...\LOCALS~1\Temp\build62924.tmp\/mmc.h:48: error: 'byte' does not name a type


C:\DOCUME~1\...\LOCALS~1\Temp\build62924.tmp\/mmc.h:49: error: 'byte' does not name a type


C:\DOCUME~1\...\LOCALS~1\Temp\build62924.tmp\/mmc.h:50: error: 'byte' does not name a type


C:\DOCUME~1\...\LOCALS~1\Temp\build62924.tmp\/mmc.h:125: error: 'byte' does not name a type


C:\DOCUME~1\...\LOCALS~1\Temp\build62924.tmp\/mmc.h:140: error: 'byte' does not name a type


C:\DOCUME~1\...\LOCALS~1\Temp\build62924.tmp\/mmc.h:157: error: 'byte' does not name a type


C:\DOCUME~1\...\LOCALS~1\Temp\build62924.tmp\/mmc.h:169: error: expected ',' or '...' before 'command'


C:\DOCUME~1\...\LOCALS~1\Temp\build62924.tmp\/mmc.h:169: error: ISO C++ forbids declaration of 'uint8_t' with no type


 In function 'void loop()':

This is the result of compilation on my office PC (Core 2 Duo, Windows XP) and I obtain about the same errors on my personnal PC on Ubuntu.

A friend compile without problems on Arduino - 0011 Alpha but this software version does not support AMD-64 architecture.


Someone already have this problem ?

What I must change to compile on 0012 software ?

Please help me to solve this problem.

Thanks.

I can compile code mmc1_v2 with Arduino - 0011 Alpha on my office PC (Core 2 Duo, Windows XP).

What the differences between 0012 and 0011 compiler ?

Apparently the problem comes to byte type. Is there any problems with byte definition with C++ ?

[Reply #3 on:]

The problem is solved (partialy) !

For an Arduino - 0012 Alpha, byte does not a type, it must be replace by unsigned char on all librairy files (mmc.h, mmc.cpp, etc).

uint8_t, uint16_t and uint32_t does not defined by default, we can defined them manually :

Code:

typedef unsigned char uint8_t;
typedef unsigned int uint16_t;
typedef unsigned long uint32_t;

Or include stdint.h in mmc.h for example :

Code:

#include <stdint.h>

It's necessary to compile microfat librairies : http://arduinonut.blogspot.com/2008/04/ufat.html

The code compile on my office PC on Windows and on my PC on Ubuntu-64 but I don't check it because I don't receive my microSD reader and file must be created on the begining of SD card to use this librairy.

[Reply #4 on:]

Rather than changing the code, you may be able to compile it by including "WProgram.h" in the header and cpp files.

[Reply #5 on:]

WProgram.h define stdint.h but byte could be always a problem, no ?

[Reply #6 on:]

WPprogram.h includes wiring.h which is where the arduino typedef for byte is found. Note that including wiring.h directly causes problems in version 0012. Did you try to include WProgram.h ?

[Reply #7 on:]

I can't compile with WProgram.h inclusion.

The problem is difficult to solve, I don't succeed to obtain compilation without errors when I try simply to include WProgram.h in differents headers.

[Reply #8 on:]

Hi,

Sorry to hear you're having compilation problems - the move to version 0012 broke quite a few of my sketches

Are you still having the problem?

[Reply #9 on:]

I was able to get mmc1_v2 to compile by:

a) adding #include <WProgram.h> at the top of mmc.h
b) deleting the wprogram.h tab in the project.

(I'm using 0013, but I bet it works for 0012 also.)

I had this same problem with a library I'm writing. (A reference to the byte type in the library header generates a compilation error.) The Morse tutorial example is out of date and talks about #including "WConstants.h" in your header. But as noted by mikalhart substituting #include <WProgram.h> works like a charm. Thanks for the solution.

I'm using 0013 on Windows.
