Don't Panic! The writer of this README is an even bigger 9 fool than you could be (even if old Ben wonders if those who follow fools are 10 more foolish). 11 12 So here's where you get started building illumos on ARM. 13 14 Step 1) You need to get a build environment set up. There's the easy way and the 15 fun way. 16 17 Easy way: 18 19 cd $HOME 20 curl -O https://fingolfin.org/illumos/arm/armtc.tar.gz 21 pfexec tar xvzf armtc.tar.gz -C / 22 find /opt/armtc 23 24 Fun way: 25 26 Using a normal i386 on i386 build: 27 cd usr/src 28 dmake setup 29 cd cmd/sgs 30 dmake install 31 32 mkdir -p /opt/armtc/lib/amd64 /opt/armtc/usr/bin/amd64 33 cd /opt/armtc/lib/ 34 ln -s amd64 64 35 cd ../usr/bin 36 ln -s amd64 64 37 38 Then from your proto area, install the following: 39 o /usr/bin/ld 40 o /usr/bin/amd64/ld 41 o /lib/libld.so.4 42 o /lib/amd64/libld.so.4 43 o /lib/liblddbg.so.4 44 o /lib/amd64/liblddb.so.4 45 o /lib/libelf.so.1 46 o /lib/amd64/libelf.so.1 47 48 Now that's all set go grab illumos-arm-extra (git clone 49 gitosis@zelgadis.fingolfin.org:illumos-arm-extra.git) and build that. You'll 50 need something like: 51 52 gmake ARCH=arm STRAP=strap LD_ALTEXEC=/opt/armtc/usr/bin/ld install 53 54 Once that's done, you'll need to fix up the rpath there. so from the root of 55 that workspace run: 56 57 ./tools/setrpath proto-arm/usr/ /opt/armtc/usr/lib:/opt/gcc/4.4.4/lib:/lib:/usr/lib 58 59 Finally, you can copy all of that into your arm compiler toolchain directory 60 (use pfexec / sudo as appropriate): 61 62 cp -r proto-arm/usr /opt/armtc/ 63 64 Step 2) Set up illumos.sh 65 66 In a fresh workspace, you're going to want to set up your illumos.sh with the 67 following: 68 69 # Enable GCC 4 default 70 export __GNUC=""; 71 export CW_NO_SHADOW=1 72 export MACH=arm; 73 export NATIVE_MACH=i386; 74 export BUILD64="#" 75 76 # Re-set all this MACH-based crud 77 REF_PROTO_LIST=$PARENT_WS/usr/src/proto_list_${MACH}; export REF_PROTO_LIST 78 ROOT="$CODEMGR_WS/proto/root_${MACH}"; export ROOT 79 PARENT_ROOT=$PARENT_WS/proto/root_$MACH; export PARENT_ROOT 80 PKGARCHIVE="${CODEMGR_WS}/packages/${MACH}/nightly"; export PKGARCHIVE 81 unset GCC_ROOT GNU_ROOT CW_GCC_DIR 82 export i386_GCC_ROOT=/opt/gcc/4.4.4 83 export arm_GCC_ROOT=/opt/armtc/usr 84 export i386_GNU_ROOT=/usr/sfw 85 export arm_GNU_ROOT=/opt/armtc/usr/gnu 86 87 # 88 # XXX our gcc isn't called ./usr/bin/gcc fix it up via CW env vars for now. 89 # 90 export CW_arm_GCC=/opt/armtc/usr/bin/arm-pc-solaris2.11-gcc-4.6.3 91 92 # 93 # XXX We need to set CPP to our specific cpp, not the generic /usr/ccs/lib/cpp 94 # as that's rather, well, x86. 95 # 96 export CPP=/opt/armtc/usr/lib/cpp 97 export AW_CPP=/opt/armtc/usr/lib/cpp 98 export LD_ALTEXEC=/opt/armtc/usr/bin/ld 99 100 Step 3) Start your build engines 101 102 Once you've done that, you're doing to need to need to use the *new* bldenv to 103 get started building. For the first time you can go ahead and do something like: 104 105 cd usr/src 106 ksh93 ./tools/scripts/bldenv.sh ../../illumos.sh 107 108 This is really just a bit of a bootstrapping weirdness. Once that's done you can 109 go ahead and continue on. 110 111 As a part of this you should see an important two lines: 112 113 Cross-building enabled 114 Targeting arm on i386 115 116 If you don't, stop. illumos.sh is not configured correctly. 117 118 119 Once you have that you can get going. Start off with a resounding: 120 121 dmake setup 122 123 Following this, you can build the kernel as far as we have it for ARM 124 125 cd uts; dmake install 126 127 You now have a lovely unix and boot_archive pair in bcm2835/unix (raspberry 128 pi) and qvpb/unix (qemu versatilepb). These should be booted with a kernel 129 command line mimicing that of the boot_archive (regardless of the path of the 130 unix you actually provide). For example: kernel /platform/bcm2835/kernel/unix 131 -Bconsole=text 132
