CogVM source as per VMMaker.oscog-eem.274.
Fix PC-mapping for NewspeakV4. Absent receiver sends must not be maped twice, once for IsNSSend and once for IsSend. So introduce class vars that state whether instructioon set uses PushImplicitReceiver (NSSendIsPCAnnotated is true) or SendAbsentImplicit (NSSendIsPCAnnotated is false). More info on optimizations to defeat for gcc 4.x compilation. git-svn-id: http://squeakvm.org/svn/squeak/branches/Cog@2704 fa1542d4-bde8-0310-ad64-8ed1123d492a

12+
13+
Checking out sources
14+
-------------------------------
15+
To generate a VM check-out http://www.squeakvm.org/svn/squeak/branches/Cog/image
16+
which contains
17+
http://www.squeakvm.org/svn/squeak/branches/Cog/image/VMMaker-Squeak4.1.changes
18+
http://www.squeakvm.org/svn/squeak/branches/Cog/image/VMMaker-Squeak4.1.image
19+
Start up VMMaker-Squeak4.1.image. In it is a workspace containing a doit that
20+
uses something like generate:and:to:platformDir:excluding:. Doit.
21+
22+
23+
How to build the Cog Croquet VM on Unix
24+
-------------------------------
25+
1. Install the tools (gcc, X11-devel, etc (e.g. libpng, libX11 & libxt source))
26+
2. Check out the following sources from svn (if you haven't already - if you're
27+
reading this in unixbuild its likely you've already got the sources)
28+
svn co http://www.squeakvm.org/svn/squeak/branches/Cog/platforms
29+
svn co http://www.squeakvm.org/svn/squeak/branches/Cog/src
30+
svn co http://www.squeakvm.org/svn/squeak/branches/Cog/unixbuild
31+
3. Open a shell, cd into the unixbuild/bld directory and execute
32+
../../platforms/unix/config/configure --without-npsqueak CFLAGS="-g -O2 -msse2 -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -DNDEBUG -DITIMER_HEARTBEAT=1 -DNO_VM_PROFILE=1 -DCOGMTVM=0 -DDEBUGVM=0" LIBS=-lpthread
33+
make install prefix=WhereYouWantTheVmToGo
34+
35+
N.B. If you're on a 64-bit linux read 3e below!!
36+
N.B. On Ubuntu *do not* supply "LIBS=-lpthread", i.e. use
37+
../../platforms/unix/config/configure --without-npsqueak CFLAGS="-g -O2 -msse2 -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -DNDEBUG -DITIMER_HEARTBEAT=1 -DNO_VM_PROFILE=1 -DCOGMTVM=0 -DDEBUGVM=0"
38+
39+
4. At the end of it you'll get a new VM in the path provided via -prefix
40+
41+
N.B. The plugin set is defined by plugins.ext and plugins.int in the build dir.
42+
43+
44+
3a. For an assert-enabled VM do
45+
../../platforms/unix/config/configure --without-npsqueak CFLAGS="-g -O1 -msse2 -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -DITIMER_HEARTBEAT=1 -DNO_VM_PROFILE=1 -DCOGMTVM=0 -DDEBUGVM=0" LIBS=-lpthread
46+
47+
3b. For a full debug VM do
48+
../../platforms/unix/config/configure --without-npsqueak CFLAGS="-g3 -msse2 -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -DITIMER_HEARTBEAT=1 -DNO_VM_PROFILE=1 -DCOGMTVM=0 -DDEBUGVM=1" LIBS=-lpthread
49+
50+
3c. For a multi-threaded VM open a shell and cd to the mtbld directory. Then
51+
execute
52+
../../platforms/unix/config/configure INTERP=cointerpmt --without-npsqueak CFLAGS="-g -O2 -msse2 -DNDEBUG -DCOGMTVM=1 -DDEBUGVM=0 -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -DITIMER_HEARTBEAT=1 -DNO_VM_PROFILE=1" LIBS=-lpthread
53+
make squeakmt
54+
make installmt prefix=WhereYouWantTheVmToGo
55+
56+
N.B. As of early 2010 the linux pthreads implementation doesn't appear to
57+
provide a way of setting priorities for the default thread scheduling policy
58+
SCHED_OTHER (unlike e.g. Mac OS X) and doesn't appear to allow changing the
59+
policy to one that does (e.g. SCHED_RR). So for now we use the itimer
60+
scheme. See platforms/unix/vm/sqUnixHeartbeat.c
61+
62+
3d. If you want to get the Cog VM simulator working you'll need to build the
63+
BochsIA32Plugin/BochsIA32Plugin.xcodeproj project and to build that you'll
64+
need to first build bochs. First check-out the processor simulator source tree
65+
containing Bochs:
66+
svn co http://www.squeakvm.org/svn/squeak/branches/Cog/processors
67+
Then build libraries linuxbochs/{cpu/libcpu.a,disasm/libdisasm.a,fpu/libfpu.a}
68+
$ cd ROOT/processors/IA32/linuxbochs
69+
$ ./conf.COG
70+
$ ../bochs/makeem
71+
and build the plugin via
72+
$ cd ROOT/unixbuild/bld/BochsIA32Plugin
73+
$ make
74+
75+
3e. (see Compiling in 32-bit mode on a 64-bit linux below)
76+
If you're building the VM on a 64-bit OS, you'll need a compiler which can
77+
compile and link to 32-bit binaries. On most Linuxes the gcc-multilib package
78+
provides the 32-bit compiler and the ia32-libs provides the 32-bit libraries.
79+
You'll also have to add the -m32 switch to all gcc & g++ invocations. The
80+
easiest way to do this is to add CC="gcc -m32" & CXX="g++ -m32" to the configure
81+
script:
82+
../../platforms/unix/config/configure CC="gcc -m32" CXX="g++ -m32" --without-npsqueak CFLAGS="-g -O2 -msse2 -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -DNDEBUG -DITIMER_HEARTBEAT=1 -DNO_VM_PROFILE=1 -DCOGMTVM=0 -DDEBUGVM=0" LIBS=-lpthread
83+
To run a 32-bit VM on a 64-bit OS, you'll also need the 32-bit libraries
84+
provided by the ia32-libs package.
85+
86+
Compiling in 32-bit mode on a 64-bit linux
87+
-------------------------------
88+
Follow 3e. above. Also note that according to Paul DeBruicker the following
89+
packages need to be installed to compile in 32-bt mode on 64-bit ubuntu. YMMV.
90+
91+
build-essential
92+
lib32asound2-dev
93+
libgl1-mesa-dev
94+
libglu1-mesa-dev
95+
ia32-libs
96+
gcc-multilib
97+
g++multilib
98+
99+
In addition [email protected] installed libc6dev-i386.
100+
101+
This in itself may not be enough, but persistence will pay off. See for example
102+
http://permalink.gmane.org/gmane.comp.lang.smalltalk.pharo.devel/75198.
103+
104+
105+
Testing an external plugin has completely linked
106+
-------------------------------
107+
You may find that an external plugin compiles and links but does not load.
108+
This is usually because it contans undefined symbols. To find undefined
109+
symbols, remake the plugin, capturing the link step and then supply
110+
-Wl,--warn-unresolved-symbols -Wl,--no-allow-shlib-undefined
111+
when manually repeating the link command
112+
113+
114+
Optimization level and gcc version
115+
----------------------------------
116+
There are issues with gcc version > 4.2.1. Any of the following flags may break the build at -O2:
117+
-ftree-pre
118+
-fpartial-inlining
119+
