cannot copy files larger than 40 MB from CD

cannot copy files larger than 40 MB from CD

[Nerijus Baliunas]

Hello,

Just began to use 2.4.7 instead of 2.2.19. If I copy file larger than 40 MB,
only these 40 MB are copied (40960000 bytes exactly), and then cp
segfaults (the same happens with mc). The same problem is with mkisofs -
only 40 MB of image is created. I get "File size limit exceeded".

Nerijus

Tried vfat, ext2 and reiserfs.

BTW, kernel is compiled with gcc-2.96-85, glibc-2.2.2-10 (RH 7.1) if that matters.

Have you tried compiling your kernel using kgcc?

gcc-2.96.* is known to compile code incorrectly AFAIK, and shouldn't be
used for compiling kernels. (kgcc is egcs-1.1.2, I think.)

No.

As I remember Alan said recent 2.4 kernels should be compiled with gcc 2.95
or 2.96 (preferably?).

Everything that I've seen recommends egcs-1.1.2. The kernel documentation
(linux/Documentation/Changes) recommends that version of egcs, as do some
list messages around 12/00.

Please read message which was posted a few minutes ago (in another thread).
2.4.7 even does not compile with egcs.

Sure it does. You just need a newer binutils. (I know, I've got a RH 6.2
box running with 2.4.7-ac3 and ext3 patches, compiled with egcs 1.1.2 and
the binutils from RH 7.1. It helps to correctly interpret the error
messages...)

Huh?  Might I recommend this (or some variant)?

[x86 hat on]

egcs-1.1.2 aka kgcc wont build 2.4.7 it seems. gcc 2.96 >= 2.96.75 or so is
just fine, gcc 2.95-2/3 is fine, gcc 3.0 seems to be doing the right thing

gcc 2.95.4 seem to be working too.

I've seen no problem running 2.4.7 built with egcs-1.1.2 2.91.66:
which part of it is believed not to build or to build wrongly?
(arch/i386/kernel/traps.c errors were identified as old binutils.)

egcs-1.1.3 *does* build 2.4.7, if you use the right binutils
(2.10.91.0.2 worked for me). I'm running 2.4.7-ac3 with ext3 patches on an
old dual P200. Haven't had a crash yet, been up 2 days and counting.
