INSTALL for procps version 2.0.1
================================
Please read the NEWS and BUGS files, also.
==========================================
Re-compiling the package
========================
You want to examine the first 30 or so lines of the Makefile (up to the
configurability note). The destinations of various things attempt FSSTND
compliance, and are pretty standard. The CC/LD flags and which libraries you
use for curses/termcap are here also. It is all annotated there and in a
readily understood format: directories, program to installdir mapping,
sub-packages to build, and compilation options. A few extra points worth
mentioning are:
o The SUBDIRS variable is essentially just a list of subdirectories to
perform a recursive make or make install in. Right now that's just
ps; the old xproc has been removed because it was entirely redundant.
o There is also an option to build and link against a libproc.so which
reduces 'ps' and 'top' sizes by a large fraction. It is on by default,
so change the value of SHARED if you want.
o 'make libinstall' will install the library and header files into standard
system directories for developers of /proc utilities. There are no
library man pages yet, but the headers are fairly well documented.
o You may need to change the INCDIRS definition if your system is
not very standard. The current definition has been tested to work
on several different systems, though.
Once you are satisfied with the top-level Makefile options (and possibly those
in subdirectories) you compile and install the package like so:
(ignore innocuous `rcsid' defined-but-not-used warnings.)
make distclean # clean-out everything to re-make from scratch
make # takes about 0.75 minutes on a PPro 200 with SCSI
su # for write/chown-perms on sys dirs
make install
ldconfig -v # update ld.so to use new libproc if SHARED=1
exit
make distclean # remove anything that can be rebuilt
Miscellaneous Notes
===================
COMPATIBILITY
This code is intended for use with Linux 2.0.xx and 2.2.xx.
Both libc 5 and libc 6 should work.
PS/TOP WCHAN FIELD
In past releases, in order to get WCHAN output for ps, you had to
have a psdatabase for each zImage kernel that you generated from
the vmlinux unstripped binary with /sbin/psupdate. With this release,
you should use the System.map automatically generated by Linus' makefile.
'ps' and 'top' will first use the contents of an environment variable
"PS_SYSTEM_MAP" and then look for System.map files along
the followin search path:
/boot/System.map-V, /boot/System.map, /lib/modules/V/System.map,
Here 'V' is the output of "uname -r" and looks like "2.2.0".
Don't forget the dash! In those same locations, remove psdatabase* files.
PARTIAL INSTALLATION
If you just want to install one program use the targets
install_progname and install_progname.X (where X is the man section)
instead. E.g.
make install_ps install_ps.1
Likewise for component packages, e.g.
make install_psmisc
