Wondering about VM sizes

Hi Guys -

Looking at download sizes for Croquet today I was somewhat astonished by
the size differences in the various VMs. Looking at the VMs in Croquet I
find that the sizes for the platforms are:

Win32: 1,090,259 bytes
Unix: 4,174,760 bytes
Mac: 7,332,608 bytes

I haven't looked at the details but I'm surprised to see such
differences. Do you have any ideas why the Unix and Mac VM are *that*
much larger than the Win32 VM? I can understand some of it given that
the Mac VM is a "universal" binary (probably including PPC as well as
Intel binaries) but that still leaves a factor of 3-4 which simply
amazes me.

Any explanations? Are there plugins built with either the Unix or Mac VM
which take that space and that I'm simply not building for Windows? Any
other causes?

Curious,
- Andreas

Ah! That explains it. So is the Mac VM 2x VM+Symbols?

Cheers,

I'm not sure which VM you are looking at?

5,786,040 is the size of 3.8.12b2u VM

There is 488K for pretty icons.

The VM is 2,368,008 bytes

[otter:Squeak 3.8.12beta2U.app/Contents/MacOS] johnmci% lipo -
detailed_info Squeak\ VM\ Opt
Fat header in: Squeak VM Opt
fat_magic 0xcafebabe
nfat_arch 2
architecture i386
cputype CPU_TYPE_I386
cpusubtype CPU_SUBTYPE_I386_ALL
offset 4096
size 1190512

architecture ppc
cputype CPU_TYPE_POWERPC
cpusubtype CPU_SUBTYPE_POWERPC_ALL
offset 1196032
size 1171976

Croquet plugin is 108k
floatmath is 140k
mpe3plugin is 564k
printjob plugin is 164k
FFI prims is 136k

Likely you don't have any of the following plugins

FT2plugin (for Type Type support) is 1.3MB since it includes the
FreeType2 library statically linked
localeplugin is 100k
quicktime plugin is 100k
services plugin is 100k
spelling plugin is 168k
TestOSAplugin (applescript) is 108k
