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 Envrioment ======== 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 ========================= https://www.uclibc.org/downloads/binaries/0.9.30.1/mini-native-x86_64.tar.bz2 1. extract device mapper source code 2. extract mini-native-x86_64.tar.bz2 3. chroot to mini-native-x86_64 3. ./configure --disable-nls --disable-selinux --disable-shared --enable-static_link 4. make 5. strip dmsetup/dmsetup.static 6. get dmsetup/dmsetup.static as the dmsetup64 binary file
