That patch should merge my accidentally written INSTALL file with that
already present in the git tree.
It adds following items:
- static compilation
- cross compilation
And updates the instructions to build the auto-generated files to use the
"bootstrap" script already present.

Installation
|
|
============
|
|
|
|
|
|
Checkout from git
|
|
-----------------
|
|
|
|
If you use the tarball, you can just skip that section. If you checked out the
|
|
kexec-tools from git repository, you have to build the Autoconf-generated
|
|
file yourself with running
|
|
|
|
./bootstrap
|
|
|
|
You have to install "autoconf" for that. After that, you should have a file
|
|
called "configure" in the top-level directory of kexec-tools, and you can
|
|
continue with the next step.
|
|
|
|
|
|
General
|
|
-------
|
|
|
|
You should check first if your favourite Linux distribution doesn't offer a
|
|
package. If that package is recent enough, you should consider using that
|
|
package instead.
|
|
|
|
However, if you want to install kexec-tools from sources
|
|
|
|
(1) Run ./configure [--prefix=/usr/local] [options]...
|
|
e.g.
|
|
|
|
./configure --prefix=/usr/local
|
|
|
|
For a full list of options run
|
|
|
|
./configure --help
|
|
|
|
(2) Run make
|
|
|
|
make
|
|
|
|
(3) To install kexec-tools
|
|
After following the above instructions to build-kexec tools, run
|
|
|
|
make install
|
|
|
|
|
|
Static compilation
|
|
------------------
|
|
|
|
To compile kexec-tools statically (i.e., independent of libraries that are
|
|
present on the system), use
|
|
|
|
LDFLAGS=-static ./configure <options>
|
|
|
|
instead.
|
|
|
|
|
|
Cross compilation
|
|
-----------------
|
|
|
|
Because kexec is also used in the embedded world, cross-compilation is
|
|
supported. You cannot only set "CC", "LD", "CCFLAGS" and "LDFLAGS" environment
|
|
variables for the ./configure call as usual, you can also set
|
|
|
|
TARGET_CC -- the C compiler used for files that should run on the
|
|
target
|
|
TARGET_CCFLAGS -- compilation flags for $TARGET_CC
|
|
TARGET_LD -- linker used for files that should run on the
|
|
target
|
|
|
|
Because the build process also requires files that must be executed during the
|
|
build, you also need a host compiler, only the target compiler is not enough.
|
|
|
|
BUILD_CC -- the C compiler used for files that should run on the
|
|
host (the system that builds the kexec-tools)
|
|
BUILD_CFLAGS -- compilation flags for $BUILD_CC
|
|
