I tried to build 2.4.18-3 kernel for kgdb 1.5 setup using instructions
below. And #make bzImage failed. I wonder someone who had built
kernel for kgdb before could tell what I went wrong. Here is what I did
compare with instructions:
>On developement machine:
>1. Extract a kernel source
>$ cd /mnt/work/build/old-pc
>$ bunzip2 -c ~/linux-2.4.6.tar.bz2 | tar xvf -
>$ mv linux linux-2.4.6-kgdb
I did:
Becuase kernel-source package is in /usr/src/linux-2.4.18-3, I simply
#cp -R linux-2.4.18-3 linux-2.4.18-3-kgdb
I don't know why need to rename the source directory as instructions
suggested.
>2. Apply kgdb patch
>$ cd linux-2.4.6-kgdb
>$ patch -p1 < ~/linux-2.4.6-kgdb.patch
I did:
#cd linux-2.4.18-3-kgdb
#patch -p1 < ~/download/kgdb/linux-2.4.18-kgdb-1.5.patch
at this stage, it went smoothly.
>3. Configure the kernel
>$ make xconfig or make menuconfig
>$ make dep
I did:
#make menuconfig
#make dep
these two steps went through smoothly
#make bzImage

Your help will be appreciated,
