BUILDING LVM2 FOR USE ON ANDROID

This is a lvm2-2_20_102 version built for android. First thanks in advance for steven676's instruction (Address at https://github.com/steven676/android-lvm-mod/blob/master/HOWTO-BUILD).

Here is my pc info:

1.Ubunto info Distributor ID: Ubuntu Description: Ubuntu 12.04 LTS Release: 12.04 Codename: precise

2.arm gcc info arm-linux-gcc-4.3.2

3.lvm version lvm2-2_20_102

Set up cross compilation enviroment

The package contains the codes and build results and could be achieved in the following way:

1. Download arm gcc to your build enviroment, and decompress it at anyplace you'like. Here i use arm-linux-gcc-4.3.2 and uncompresses it to /armlinux

2. Install standard c enviroment. apt-get install build-essential libncurses5-dev

3. Add to PATH at the end of the file. gedit ~/.profile Content as follows:

   if [ "$BASH" ]; then if [ -f ~/.bashrc ]; then . ~/.bashrc fi fi

   mesg n

   TZ='Asia/Shanghai'; export TZ; export PATH=$PATH:/armlinux/usr/local/arm/4.3.2/bin

4. Make it become effect source ~/.profile

Build lvm

1. Download Lvm2 codes from the Home Page (https://git.fedorahosted.org/git/lvm2.git). I choose lvm2-2_20_102.

2. Then follow the instruction according to steven676's guide. Here i made a shell file named build.sh: export CC=arm-linux-gcc-4.3.2 ./configure --host=arm-linux-gnueabi --prefix=/lvm --enable-static_link
   --disable-readline --disable-selinux
   --with-pool=none --with-cluster=none
   --with-confdir=/lvm/etc --with-default-run-dir=/data/lvm/run
   --with-default-system-dir=/lvm/etc --with-default-locking-dir=/data/lvm/lock
   --with-optimisation="-Os -march=armv5te -mtune=cortex-a8 -mthumb"
   make For more information can visit(https://github.com/steven676/android-lvm-mod/blob/master/HOWTO-BUILD).

Special Instructions:

To solve the build erro with rpl_malloc: ../libdm/libdevmapper.so: undefined reference to `rpl_malloc' collect2: ld returned 1 exit status make[1]: *** [dmsetup] Error 1 I modified config.h.in file
#undef malloc -> //#undef malloc #undef realloc -> //#undef realloc

The resulting statically linked unstripped LVM binary will be located in tools/lvm.static in the LVM source tree, and an example configuration file is located in doc/example.conf.
