 Posted: Sat Aug 09, 2003 12:34 pm Post subject: Can't compile any kernel |
 |
|
Hi guys,
as the Subject says: I can't get my kernel (actually I tried linux-2.4.20-gaming-r3 and linux-2.4.20-gentoo-r5) to compile  . This is the error I get:
| Code: |
super.c: In function `read_super_block':
super.c:869: Warnung: int format, long unsigned int arg (arg 2)
super.c:944:14: missing terminating " character
super.c: In function `reread_meta_blocks':
super.c:945: error: stray '\' in program
super.c:945: error: `ld' undeclared (first use in this function)
super.c:945: error: (Each undeclared identifier is reported only once
super.c:945: error: for each function it appears in.)
super.c:945: error: parse error before "n"
super.c:945:12: missing terminating " character

I'm using gcc-3.3 and have glibc-2.3.2-r2 installed.
Would be glad for any help, 'cos I have to recompile the kernel for Promise Ultra100 controller support...
EDIT: OK I see that its not necessary for controller support - but still I want to be able to compile my kernel, wouldn't you?
Thx,
tragor |

Interesting - it looks like you've stumbled across a minor bug in the kernel code. If you cd to /usr/src/linux-2.4.20-gentoo-r5/fs/reiserfs and edit super.c, you'll see that lines 944-945 in reread_meta_blocks() look like this:
printk("reread_meta_blocks, error reading bitmap block number %d at
%ld\n", i, SB_AP_BITMAP(s)[i].bh->b_blocknr) ;
The bug here is in the line break between at and %ld. The newest versions of gcc spit out an error if there's an unmarked line break within a string. To fix it, just add a \ at the end of the first line, so gcc knows the string continues on to the next line. Or use a newer kernel - this problem seems to be fixed in 2.4.21. |

I will try out a newer version if its stable, I think ... I can't recall, what error I got from compiling the gaming source. But it's strange that there was a bug too, no?

So I could not find the 2.4.21 - is there a ebuild for it?
So I tried to fix the bug myself as suggested. Now I get another error further down the compilation:
| Code: |
In file included from ide-cd.c:320:
ide-cd.h:440: error: long, short, signed or unsigned used invalidly for `slot_tablelen'
make[2]: *** [ide-cd.o] Fehler 1
make[2]: Leaving directory `/usr/src/linux-2.4.20-gentoo-r6/drivers/ide'
make[1]: *** [_modsubdir_ide] Fehler 2
make[1]: Leaving directory `/usr/src/linux-2.4.20-gentoo-r6/drivers'
make: *** [_mod_drivers] Fehler 2
|
So why is that? Another simple error that can be fixed? Or may I have a more serious problem?
Thanks for help,

emerge vanilla-sources
If you're still getting 2.4.20 from that, you need to run `emerge rsync' to update your copy of the Portage database.

2.4.21 changes that line from `__u8 short slot_tablelen;' to `__u16 slot_tablelen;', which is presumably the right fix.
