[lcd4linux] compile fails with gcc 3.4.1

[Heiko Z. <he...@zu...>]

Hey guys,

just tried to compile lcd4linux v0.9.11 with gcc 3.4.1 (+ glibc 2.3.4 + 
nptl) and ran into an error:

I don't think this is related to gcc, but your header files. system.c 
includes if_ppp.h, which triggers this error. Maybe one needs to inclode 
some other header before if_ppp.... If you take a look at the 
crc-ccitt.h file, at line 6, what is there "before const"? Next, try 
where this symbol gets defined, and try to include this file manually.

btw, you could and should try the CVS version of lcd4linux. The code is 
stable, it just lacks documentation...


bye, Michael

This is the crc-ccit.h file:
--- snip ---
#ifndef _LINUX_CRC_CCITT_H
#define _LINUX_CRC_CCITT_H

#include <linux/types.h>

extern u16 const crc_ccitt_table[256];

extern u16 crc_ccitt(u16 crc, const u8 *buffer, size_t len);

static inline u16 crc_ccitt_byte(u16 crc, const u8 c)
{
        return (crc >> 8) ^ crc_ccitt_table[(crc ^ c) & 0xff];
}

#endif /* _LINUX_CRC_CCITT_H */
--- snap ---

the types u16 and u8 are not defined. I replaced them with __u8 and 
__u16 and everything works fine.

I tried the CVS version, but it had the same problem.
   
Of course I forgott to mention 1 'small' little detail, I'm using Kernel 
2.6.8.1.

Thanks for the help !

Hmmm... modifying some glibc (or kernel) include files just to get 
lcd4linux working... hmmm.... I'd not consider this 'clean' :-)

maybe you could search for where u16 and u8 are defined. Maybe it's 
sufficient to include this file just before if_ppp.h. On the other hand, 
maybe if_ppp.h should include these necessary files itself...

This should be no problem, as I'm using the same kernel here.

Well, I must say that I never tried the latest "official" lcd4linxu 
release 0.9.11 with Kernel 2.6

The upcoming 0.10 release is nearly finished, the code seems stable, but 
it lacks documentation. Maybe you wanna try the CVS version? (but be 
warned: it changed a lot!)

As I already wrote, the CVS versieon (which will be 0.10) has support 
for kernel 2.6, and therefore parses /proc/diskstat.

I have tried the CVS version but i didnt get it to work :( I don't know
why, I have tried my HD44 in 4 and 8 bit mode, and changed the wirings
too, but my HD keeps doing nothing in any Layout - style.
I just choose to change some lines in my downloaded v0.9.11 instead and
that works fine now.

I will provide a diff if anyone needs it.

have a nice day, janK

Strange. Could you please post your (currently working) 0.9 .conf, and 
the (not working) CVS .conf? And an output of "lcd4linux -Fvv" from the 
CVS version?

I really would like to take a look at it!
