makedumpfile's README
=======================
* REQUIREMENTS
Please download the following library file and install it exactly as below;
do NOT use "make install".
- elfutils-0.125.tar.gz
The "make install" of elfutils installs some commands (ld, readelf, etc.),
and compiling problems sometimes happen due to using the installed
commands. To install only the library & header files, use the following
method:
# tar -zxvf elfutils-0.125.tar.gz
# cd elfutils-0.125
# ./configure
# make
#
# mkdir /usr/local/include/elfutils/
# cp ./libdw/libdw.h /usr/local/include/elfutils/libdw.h
# cp ./libdw/dwarf.h /usr/local/include/dwarf.h
# cp ./libelf/libelf.h /usr/local/include/libelf.h
# cp ./libelf/gelf.h /usr/local/include/gelf.h
#
# cp ./libelf/libelf.a /usr/local/lib/libelf.a
# cp ./libdw/libdw.a /usr/local/lib/libdw.a
# cp ./libasm/libasm.a /usr/local/lib/libasm.a
# cp ./libebl/libebl.a /usr/local/lib/libebl.a
#
* BUILD & INSTALL
1.Get the latest makedumpfile from the following site:
https://sourceforge.net/projects/makedumpfile/
2.Uncompress the tar file:
# tar -zxvf makedumpfile-x.y.z.tar.gz
3.Enter the makedumpfile subdirectory:
# cd makedumpfile-x.y.z
4.Build, and install:
# make; make install
* SUPPORTED KERNELS
This makedumpfile supports the following kernels.
| FLATMEM | DISCONTIGMEM | SPARSEMEM

OK : Support.
-- : Not support.
Empty : Not test yet.
TODO : TODO.
#1 : Both kexec/kdump does not work with PPC64 2.6.20 kernels.
This is a known problem fixed with later kernels.
#2 : kdump does not work with i386 sparsemem 2.6.27 kernels.
This is a known problem fixed with later kernels.
** : The deleted memory model.
On x86_64, both FLATMEM and DISCONTIGMEM have been deleted since
linux-2.6.25.
* USAGE
Please see "man makedumpfile" or "makedumpfile -h".
* TODO
1. Supporting more kernels.
2. Fixing the report message.
(Now, it sometimes counts the number of free_pages duplicating zero-pages
if creating an ELF dumpfile.)
* NOTE
1. A vmcoreinfo file should be generated by the makedumpfile which is used
for dump filtering. If installing the latest makedumpfile, the vmcoreinfo
file should be regenerated by it. Actually, makedumpfile v1.2.0 or later
cannot work by vmcoreinfo file which is generated by v1.1.9 or before.
2. If using linux-2.6.24 and kexec-tools-testing-20061214, /proc/vmcore
contains vmcoreinfo data. So it is possible to create a dumpfile without
-x option (or -i option) like the following:
# makedumpfile -d 31 /proc/vmcore dumpfile
3. On makedumpfile-1.2.5 or before, both '--xen-syms' and '--xen-vmcoreinfo'
excluded Xen user domain pages. Since makedumpfile-1.2.6, '-X' option
have been added for excluding Xen user domain pages, and these options
does not exclude Xen user domain pages. So user should specify '-X'
option for excluding Xen user domain pages.
* FAQ
001: It cannot be compiled with the following messages:
# make
gcc -g -O2 -Wall -D__x86_64__ -c -o ./x86.o ./x86.c
gcc -g -O2 -Wall -D__x86_64__ -c -o ./x86_64.o ./x86_64.c
gcc -g -O2 -Wall -D__x86_64__ -c -o ./ia64.o ./ia64.c

/tmp/ccYv3cGF.o: In function `get_debug_info':
/tmp/makedumpfile/makedumpfile.c:1341: undefined reference to
`elf_getshstrndx'
collect2: ld returned 1 exit status
make: *** [makedumpfile] Error 1
#
The compiler cannot find elf_getshstrndx() because it tries
searching for it only from /usr/lib/libelf.a though elf_getshstrndx()
is archived in /usr/local/lib/libelf.a.
To solve the problem, add the option (-L/usr/local/lib/) to CFLAGS
of Makefile like the following:
CFLAGS = -g -O2 -Wall -D_FILE_OFFSET_BITS=64 -L/usr/local/lib/ \
-DVERSION='"$(VERSION)"' -DRELEASE_DATE='"$(DATE)"'
