-----------------------INSTALL CORE --- OK OK
Fedora 23:
dnf install bash bridge-utils ebtables iproute libev python procps-ng net-tools tcl tk tkimg autoconf automake make libev-devel python-devel ImageMagick help2man
//重要，在CORE中，执行 /root/.core/configs/m-MPE-manet.imn，不能正常初始化。需要执行如下命令。
dnf install kernel-modules-extra-`uname -r`
CentOS 7:
yum install bash bridge-utils ebtables iproute libev python procps-ng net-tools tcl tk tkimg autoconf automake make libev-devel python-devel ImageMagick help2man
You can obtain the CORE source from the CORE source page. Choose either a stable release version orthe development snapshot available in thenightly_snapshots directory.The-j8 argument tomake will run eight simultaneous
jobs, to speed upbuilds on multi-core systems. Notice theconfigure flag to tell the buildsystem that a systemd service file should be installed under Fedora.
[root@localhost core-4.8]# ./bootstrap.sh
[root@localhost core-4.8]# ./configure --with-startup=systemd
[root@localhost core-4.8]# make -j4
[root@localhost core-4.8]# make install
Note that the Linux RPM and Debian packages do not use the/usr/local prefix, and files are instead installed to/usr/sbin, and /usr/lib. This difference is a result of aligning with the directorystructure of Linux packaging systems and FreeBSD ports packaging.
Another note is that the Python distutils in Fedora Linux will install the COREPython modules to/usr/lib/python2.7/site-packages/core, instead ofusing thedist-packages directory.
The CORE Manual documentation is built separately from thedoc/ sub-directory in the source. It requires Sphinx:
sudo yum install python-sphinx
cd core-4.8/doc
make html
make latexpdf
