3 Special notes for cross-hosting a NetBSD build on certain platforms.
4 Only those platforms which have been tested to complete a "build.sh" run
5 are listed.
6
7 All hosts must have a POSIX compatible sh. /bin/sh is assumed unless
8 otherwise set. This can be overridden by setting HOST_SH in the environment.
9
10 In addition all hosts must provide the following local tools:
11 gzip
12 gcc
13 g++
14 zlib and headers (this requirement may be dropped in future)
15
16 FreeBSD
17 -------
18
19 build.sh was recently tested on:
20 * FreeBSD 13 (amd64, aarch64)
21 * FreeBSD 12.2 (amd64, aarch64)
22 * FreeBSD 11.4 (amd64)
23 * FreeBSD 10.4 (amd64)
24
25 Linux
26 -----
27
28 build.sh has been tested on:
29 * Amazon Linux 2 (x86)
30 * Debian 10 (x86, aarch64)
31 * Red Hat Enterprise Linux 8 (x86, aarch64)
32 * SUSE Enterprise Server 15 (x86)
33 * Ubuntu Server 20.04 (x86, aarch64)
34 * Ubuntu Server 18.04 (x86)
35
36 * The gcc and g++ package must be installed, along with the typical system
37 development packages (glibc-devel, etc.). The g++ package is sometimes
38 called gcc-c++.
39
40 * The ncurses-devel package must be installed (for nbinfo).
41
42 * The zlib and zlib-devel packages must be installed (these are
43 called zlib1g and zlib1g-dev on Debian and Ubuntu Linux)
44
45 * There is a known build problem on Linux/aarch64 with glibc <2.28
46
47 macOS/Darwin
48 ------------
49
50 build.sh was recently tested on:
51 * macOS Big Sur (x86)
52 * macOS Catalina
53 * macOS High Sierra
54
55 with up to date Xcode command line tools and APFS filesystems.
56 Previously, there have been issues building on case-insensitive
57 HFS filesystems. build.sh is not working yet on M1-based Macs.
58
59 HP-UX
60 -----
61
62 * zlib must be available.
63
64 OpenBSD
65 -------
66
67 As of -current 20210629, ./build.sh will build src on OpenBSD 6.9
68 for all targets except MIPS-based ones.
69
70 For builds requiring the LLVM RT library (including X on amd64,
71 i386 and evbarm64-el), the build user's limits needs to be setup
72 for higher memory usage, otherwise the build will fail. This can
73 be achieved by either building as root (not recommended) or
74 by changing the datasize attribute to infinity for the relevant
75 groups and users in /etc/login.conf.
76
77 NetBSD (earlier releases)
78 -------------------------
79
80 * Tested on NetBSD 1.5.2 (machine-independently).
81 * Should need no special setup.
82 * _NETBSD_SOURCE is *not* to be defined/pulled in during compat/tools builds.
83 compat_defs.h will error out if it finds it defined.
84
85 Solaris
86 -------
87
88 (updated instruction for Solaris 11 further below)
89
90 * Tested on Solaris/x86 8 (5.8) with gcc 2.95.2 and Solaris/sparc 8 (5.8)
91 with gcc 3.2 (not yet tested with SUNWspro).
92
93 * $HOST_CC needs to be set properly (for gcc, it should be set to "gcc",
94 otherwise the improper /usr/ucb/cc may be invoked by accident).
95
96 * The SUNWzlib package (or a built version of zlib visible to $HOST_CC,
97 such as SMCzlib from sunfreeware.com) must be installed. This will be
98 fixed in the future to include zlib in libnbcompat.
99
100 * Needs the following paths, in this order, in $PATH:
101
102 /usr/xpg4/bin
103 /usr/ccs/bin
104 <path to host C and C++ compilers>
105 /usr/bin
106
107 /usr/ucb may optionally be placed before /usr/bin, per your preference,
108 but /usr/ucb *MUST NOT* be before /usr/ccs/bin or before the path to
109 the host C and C++ compilers.
110
111 Solaris 11:
112
113 * Solaris 11.3
114 * Set PATH to /usr/xpg6/bin:/usr/xpg4/bin:/usr/bin
115 * Set HOST_CC to /usr/bin/gcc
116
117 * Solaris 11.4
118 * Install gcc-5 since the default installed gcc-7 has issues when compiling
119 toolchain version of groff (hypot())
120 * Set PATH to /usr/xpg7/bin:/usr/xpg6/bin:/usr/xpg4/bin:/usr/bin
121 * set HOST_CC to /usr/gcc/5/bin/gcc
122 * set HOST_CXX to /usr/gcc/5/bin/g++
