1 $NetBSD: README,v 1.19 2021/06/29 10:02:34 cjep Exp $ 2 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 some platforms. Known problems: 69 * MIPS targets do not currently build. 70 * The LLVM RT library will not build and consequently nor will X on 71 amd64 and i386. 72 73 NetBSD (earlier releases) 74 ------------------------- 75 76 * Tested on NetBSD 1.5.2 (machine-independently). 77 * Should need no special setup. 78 * _NETBSD_SOURCE is *not* to be defined/pulled in during compat/tools builds. 79 compat_defs.h will error out if it finds it defined. 80 81 Solaris 82 ------- 83 84 (updated instruction for Solaris 11 further below) 85 86 * Tested on Solaris/x86 8 (5.8) with gcc 2.95.2 and Solaris/sparc 8 (5.8) 87 with gcc 3.2 (not yet tested with SUNWspro). 88 89 * $HOST_CC needs to be set properly (for gcc, it should be set to "gcc", 90 otherwise the improper /usr/ucb/cc may be invoked by accident). 91 92 * The SUNWzlib package (or a built version of zlib visible to $HOST_CC, 93 such as SMCzlib from sunfreeware.com) must be installed. This will be 94 fixed in the future to include zlib in libnbcompat. 95 96 * Needs the following paths, in this order, in $PATH: 97 98 /usr/xpg4/bin 99 /usr/ccs/bin 100 <path to host C and C++ compilers> 101 /usr/bin 102 103 /usr/ucb may optionally be placed before /usr/bin, per your preference, 104 but /usr/ucb *MUST NOT* be before /usr/ccs/bin or before the path to 105 the host C and C++ compilers. 106 107 Solaris 11: 108 109 * Solaris 11.3 110 * Set PATH to /usr/xpg6/bin:/usr/xpg4/bin:/usr/bin 111 * Set HOST_CC to /usr/bin/gcc 112 113 * Solaris 11.4 114 * Install gcc-5 since the default installed gcc-7 has issues when compiling 115 toolchain version of groff (hypot()) 116 * Set PATH to /usr/xpg7/bin:/usr/xpg6/bin:/usr/xpg4/bin:/usr/bin 117 * set HOST_CC to /usr/gcc/5/bin/gcc 118 * set HOST_CXX to /usr/gcc/5/bin/g++ 119
