在CentOS 5环境编译libvirt的困扰

在CentOS 5编译lbivirt软件包时候遇到如下报错

+ aclocal -I /usr/share/aclocal -I ./gnulib/m4/
aclocal:configure.ac:36: warning: macro `AM_SILENT_RULES' not found in library
aclocal:configure.ac:141: warning: macro `AM_PROG_LIBTOOL' not found in library
aclocal:configure.ac:146: warning: macro `AM_PROG_LD' not found in library
aclocal:configure.ac:2146: warning: macro `AM_GNU_GETTEXT_VERSION' not found in library
...

参考 Yubico/yubico-c: Unable to build #2 上述报错是因为CentOS 5 automake 版本只有1.9.6，实际对于AM_SILENT_RULES需要automake版本1.11。所以考虑升级操作系统的automake和autoconf版本。

此外，要支持编译libvirt还需要以下软件包

sudo yum install pkgconfig gettext dnsmasq radvd iptables ebtables  libpcap-devel libattr-devel libpciaccess-devel cyrus-sasl-devel libselinux-devel python-devel readline-devel libgcrypt-devel gnutls avahi-devel dbus-devel numactl-devel audit-libs-devel cmake

cmake是为了编译libvirtd编译时依赖的yajl

升级编译工具链

• （这步跳过）CentOS 5的默认gcc版本太低，可能会导致编译无法通过，改为系统提供的gcc44

sudo yum install gcc44 gcc44-c++
sudo rpm -e gcc-4.1.2-55.el5 gcc-c++-4.1.2-55.el5
cd /usr/bin
sudo ln -s gcc44 gcc
sudo ln -s gcc44 cc
sudo ln -s g++44 g++

• 升级编译以下编译工具

wget http://ftp.gnu.org/gnu/autoconf/autoconf-2.69.tar.gz
tar xfz autoconf-2.69.tar.gz
cd autoconf-2.69
./configure --prefix=/usr
make
sudo make install

wget http://ftp.gnu.org/gnu/automake/automake-1.15.1.tar.gz
tar xfz automake-1.15.1.tar.gz
cd automake-1.15.1
./configure --prefix=/usr
make
sudo make install

http://invisible-island.net/byacc/byacc.html 提供了最新的byacc版本信息

wget http://invisible-island.net/datafiles/release/byacc.tar.gz
cd byacc-20170709
./configure --prefix=/usr
make
sudo make install

wget http://ftp.gnu.org/gnu/binutils/binutils-2.29.tar.gz
tar xfz binutils-2.29.tar.gz
cd binutils-2.29
./configure --prefix=/usr
make
sudo make install

这里./configure --prefix=/usr是为了覆盖发行版自带的autoconf和automake版本，既然CentOS 5已经终止更新，不如用自己编译的版本覆盖以避免编译问题。
