Build a static linked, small dmsetup tool
======== Source Code ========
use an old version of dmsetup
http://vault.centos.org/5.3/os/SRPMS/device-mapper-1.02.28-2.el5.src.rpm
https://www.fefe.de/dietlibc/dietlibc-0.34.tar.xz
======== Build Environment ========
build for 32bit, static linked with dietlibc
1. install centos 6.10 i386 with CentOS-6.10-i386-bin-DVD1.iso
2. yum install gcc kernel-devel package
3. install dietc libc (just make && make install)
4. export PATH=$PATH:/opt/diet/bin
======== Build Step ========
1. extract device mapper source code
2. CC="diet gcc" ./configure --disable-nls --disable-selinux --disable-shared
3. modify include/configure.h file
--- delete the line with "#define malloc rpl_malloc"
--- add 2 defines as follow:
#ifndef UINT32_MAX
#define UINT32_MAX (4294967295U)
#endif
#ifndef UINT64_C
#define UINT64_C(c) c ## ULL
#endif
4. make
5. strip dmsetup/dmsetup
6. get dmsetup/dmsetup as the dmsetup32 binary file
======================== Build for 64bit dmsetup =========================
1. extract device mapper source code
2. ./configure --disable-nls --disable-selinux --disable-shared --enable-static_link CC='gcc -specs /usr/local/musl/lib/musl-gcc.specs'
3. touch include/linux/limits.h include/linux/types.h
echo '#include <sys/mount.h>' > include/linux/fs.h
4. make
5. strip --strip-all dmsetup/dmsetup.static
6. get dmsetup/dmsetup.static as the dmsetup64 binary file
======================== Build for arm64 dmsetup =========================
1. extract device mapper source code
2. ./configure CC=aarch64-linux-gcc --target=arm --host=x86_64-linux-gnu --disable-nls --disable-selinux --disable-shared --enable-static_link
3. modify include/configure.h file
--- delete the line with "#define malloc rpl_malloc"
4. make
5. aarch64-linux-strip dmsetup/dmsetup.static
6. get dmsetup/dmsetup.static as the dmsetupaa64 binary file
======================== Build for mips64 dmsetup =========================
1. extract device mapper source code
2. ./configure CC="mips64el-linux-musl-gcc -mips64r2 -mabi=64" --target=mips --host=x86_64-linux-gnu --disable-nls --disable-selinux --disable-shared --enable-static_link
3. modify include/configure.h file
--- delete the line with "#define malloc rpl_malloc"
4. make
5. mips64el-linux-musl-strip dmsetup/dmsetup.static
6. get dmsetup/dmsetup.static as the dmsetupm64e binary file
