Large Files

In order to be able to work with large (>2Gb) files under Linux any program needs the following:

1. The Linux kernel 2.4.x.
2. The C system library glibc 2.x.

In principle, having the above kernel and glibc should allow C programs to work with LFS.

Before recompiling any C programs make sure that:

1. the program #includes <stdio.h> and <unistd.h>
2. any variables used to hold the file offset values are of the type off_t or fpos_t (neither int nor long)
3. the program uses fseeko and ftello instead of fseek and ftell
4. the program is compiled with gcc -D_GNU_SOURCE -DLARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64

For example the default unzip program supplied with Red Hat 3 & 4 and CentOS 3 & 4 do not seem to be compiled with these flags
