$NetBSD: README,v 1.13 2018/09/09 19:17:21 palle Exp $
Special notes for cross-hosting a NetBSD build on certain platforms.
Only those platforms which have been tested to complete a "build.sh" run
are listed.
All hosts must have a POSIX compatible sh. /bin/sh is assumed unless
otherwise set. This can be overridden by setting HOST_SH in the environment.
In addition all hosts must provide the following local tools:
gzip
=====
NetBSD:
* _NETBSD_SOURCE is *not* to be defined/pulled in during compat/tools builds.
compat_defs.h will error out if it finds it defined.
HP-UX:
* zlib must be available.
This will be fixed in the future to include zlib in libnbcompat.
=====
LINUX:
* Tested on RedHat Linux 7.1 (i386).
Tested on RedHat Linux 7.3 (i686) on 16 Sep 2002. Requires "LANG=C"
in the environment.
* Tested on Redhat Linux 8.0 (i686) in Fall 2003. Requires no special settings.
* Tested on Redhat ES3 and AS3 in spring of 2004. Requires no special settings.
* The gcc (and libstdc++, if needed) package must be installed, along
with the typical system development packages (glibc-devel, etc.).
* The ncurses-devel package must be installed (for nbinfo).
* The zlib and zlib-devel packages must be installed. This will be
fixed in the future to include zlib in libnbcompat.
=====
MACOS
Requires a case sensitive filesystem such as UFS
* Tested on 10.2.8 with Dec 2002 Developer Tools
- may require a fix to /usr/bin/join, netbsd's join should work fine
* Tested on 10.3 with xcode 1.5
- compiles fine out of the box
=====
NETBSD (earlier releases):
* Tested on NetBSD 1.5.2 (machine-independently).
* Should need no special setup.
=====
SOLARIS:
(updated instruction for Solaris 11 further below)
* Tested on Solaris/x86 8 (5.8) with gcc 2.95.2 and Solaris/sparc 8 (5.8)
with gcc 3.2 (not yet tested with SUNWspro).
* $HOST_CC needs to be set properly (for gcc, it should be set to "gcc",
otherwise the improper /usr/ucb/cc may be invoked by accident).
* The SUNWzlib package (or a built version of zlib visible to $HOST_CC,
such as SMCzlib from sunfreeware.com) must be installed. This will be
fixed in the future to include zlib in libnbcompat.
* Needs the following paths, in this order, in $PATH:
/usr/xpg4/bin
/usr/ccs/bin
<path to host C and C++ compilers>
/usr/bin
/usr/ucb may optionally be placed before /usr/bin, per your preference,
but /usr/ucb *MUST NOT* be before /usr/ccs/bin or before the path to
the host C and C++ compilers.
Solaris 11:
* Solaris 11.3
* Set PATH to /usr/xpg6/bin:/usr/xpg4/bin:/usr/bin
* Set HOST_CC to /usr/bin/gcc
* Solaris 11.4
* Install gcc-5 since the default installed gcc-7 has issues when compiling
toolchain version of groff (hypot())
* Set PATH to /usr/xpg7/bin:/usr/xpg6/bin:/usr/xpg4/bin:/usr/bin
* set HOST_CC to /usr/gcc/5/bin/gcc
* set HOST_CXX to /usr/gcc/5/bin/g++
