Hi!

I am trying to compile linux-2.4.18 with gcc-3.2.3. Running make
bzImage creates a file bzImage of size 19152 bytes only. This is the
output of ls -l in arch/i386/boot directory:

The size of vmlinux is over 2.5Mb: ls -l vmlinux

-rwxr-xr-x 1 vrihad users 2595279 Jul 31 16:52 vmlinux

Following is the output of make bzImage from the point where vmlinux
is built:

bzImage
Root device is (3, 8)
Boot sector 512 bytes.
Setup is 4759 bytes.
System is 13 kB

Only one warning is issued by the assembler; i.e.
bsetup.s:1596: Warning: indirect lcall without `*'

What could be the problem?

Thanks in advance
vrihad
