1 $NetBSD: README,v 1.17 2021/06/28 07:16:46 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 NetBSD (earlier releases) 65 ========================= 66 67 * Tested on NetBSD 1.5.2 (machine-independently). 68 * Should need no special setup. 69 * _NETBSD_SOURCE is *not* to be defined/pulled in during compat/tools builds. 70 compat_defs.h will error out if it finds it defined. 71 72 Solaris 73 ======= 74 75 (updated instruction for Solaris 11 further below) 76 77 * Tested on Solaris/x86 8 (5.8) with gcc 2.95.2 and Solaris/sparc 8 (5.8) 78 with gcc 3.2 (not yet tested with SUNWspro). 79 80 * $HOST_CC needs to be set properly (for gcc, it should be set to "gcc", 81 otherwise the improper /usr/ucb/cc may be invoked by accident). 82 83 * The SUNWzlib package (or a built version of zlib visible to $HOST_CC, 84 such as SMCzlib from sunfreeware.com) must be installed. This will be 85 fixed in the future to include zlib in libnbcompat. 86 87 * Needs the following paths, in this order, in $PATH: 88 89 /usr/xpg4/bin 90 /usr/ccs/bin 91 <path to host C and C++ compilers> 92 /usr/bin 93 94 /usr/ucb may optionally be placed before /usr/bin, per your preference, 95 but /usr/ucb *MUST NOT* be before /usr/ccs/bin or before the path to 96 the host C and C++ compilers. 97 98 Solaris 11: 99 100 * Solaris 11.3 101 * Set PATH to /usr/xpg6/bin:/usr/xpg4/bin:/usr/bin 102 * Set HOST_CC to /usr/bin/gcc 103 104 * Solaris 11.4 105 * Install gcc-5 since the default installed gcc-7 has issues when compiling 106 toolchain version of groff (hypot()) 107 * Set PATH to /usr/xpg7/bin:/usr/xpg6/bin:/usr/xpg4/bin:/usr/bin 108 * set HOST_CC to /usr/gcc/5/bin/gcc 109 * set HOST_CXX to /usr/gcc/5/bin/g++ 110
