$NetBSD: README,v 1.21 2021/07/11 06:15:42 cjep 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
|
|
gcc
|
|
g++
|
|
zlib and headers (this requirement may be dropped in future)
|
|
|
|
FreeBSD
|
|
-------
|
|
|
|
build.sh was recently tested on:
|
|
* FreeBSD 13 (amd64, aarch64)
|
|
* FreeBSD 12.2 (amd64, aarch64)
|
|
* FreeBSD 11.4 (amd64)
|
|
* FreeBSD 10.4 (amd64)
|
|
|
|
Linux
|
|
-----
|
|
|
|
build.sh has been tested on:
|
|
* Amazon Linux 2 (x86)
|
|
* Debian 10 (x86, aarch64)
|
|
* Red Hat Enterprise Linux 8 (x86, aarch64)
|
|
* SUSE Enterprise Server 15 (x86)
|
|
* Ubuntu Server 20.04 (x86, aarch64)
|
|
* Ubuntu Server 18.04 (x86)
|
|
|
|
* The gcc and g++ package must be installed, along with the typical system
|
|
development packages (glibc-devel, etc.). The g++ package is sometimes
|
|
called gcc-c++.
|
|
|
|
* The ncurses-devel package must be installed (for nbinfo).
|
|
|
|
* The zlib and zlib-devel packages must be installed (these are
|
|
called zlib1g and zlib1g-dev on Debian and Ubuntu Linux)
|
|
|
|
* There is a known build problem on Linux/aarch64 with glibc <2.28
|
|
|
|
macOS/Darwin
|
|
------------
|
|
|
|
build.sh was recently tested on:
|
|
* macOS Big Sur (x86)
|
|
* macOS Catalina
|
|
* macOS High Sierra
|
|
|
|
with up to date Xcode command line tools and APFS filesystems.
|
|
Previously, there have been issues building on case-insensitive
|
|
HFS filesystems. build.sh is not working yet on M1-based Macs.
|
|
|
|
HP-UX
|
|
-----
|
|
|
|
* zlib must be available.
|
|
|
|
OpenBSD
|
|
-------
|
|
|
|
As of -current 20210629, ./build.sh will build src on OpenBSD 6.9
|
|
for all platforms.
|
|
|
|
Due to the default limits placed on user accounts, the host may experience
|
|
memory exhaustion on builds requiring the LLVM RT library (including
|
|
X on amd64, i386 and evbarm64-el) and for MIPS targets.
|
|
|
|
This can be avoided by building as root (not ideal) or by asking your
|
|
administrator to increase your limits in login.conf. These two variables
|
|
seem to be sufficient:
|
|
:datasize=infinity:\
|
|
:stacksize-cur=8M:\
|
|
|
|
NetBSD (earlier releases)
|
|
-------------------------
|
|
|
|
* Tested on NetBSD 1.5.2 (machine-independently).
|
|
* Should need no special setup.
|
|
* _NETBSD_SOURCE is *not* to be defined/pulled in during compat/tools builds.
|
|
compat_defs.h will error out if it finds it defined.
|
|
|
|
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++
