Comment #8 on issue 3436 by stephane.ducasse: #copyFrom: is broken http://code.google.com/p/pharo/issues/detail?id=3436 Not really but when you have copyFrom:to: copyFrom: is natural. To my eyes this looks like a missing method in the collection API.

Re: [Pharo-project] new Cog VMs

Hi All, looks like there are issues running Cog on 64-bit linux. I only have a 32-bit one to hand so it'll be a while before I can look at this. BTW, it would really help if when people post bugs they give - a URL to the image and changes, not just a name like Pharo 1.1.1. A pointer to the exact bits eliminates any possibility that I will fetch the wrong image and not be able to reproduce - the exact directory something is installed in, not just the name but the full path, and whether it is remote ounted or not. I just fixed a crash on windows for Torsten that didn't show on a remote-mounted drive but caused a hard crash if installed as c:\pharo. So saying "its in coglinux/" isn;t being precise enough.

Re: [Pharo-project] new Cog VMs

Hi Martin, crashing immediately on startup could be to do with the UUIDPlugin and libuuid. Try removing coglinux/lib/squeak/3.9-7/UUIDPlugin and see if it makes a difference. If it does I believe the fix is to ensure that there's a 32-bit libuuid.so.1 installed. e.g. [eliot@mcqfes bld]$ ldd coglinux/lib/squeak/3.9-7/UUIDPlugin linux-gate.so.1 => (0x00e2e000) libuuid.so.1 => /lib/libuuid.so.1 (0x0067e000) libc.so.6 => /lib/libc.so.6 (0x008d6000) /lib/ld-linux.so.2 (0x0045a000) [eliot@mcqfes bld]$ file /lib/libuuid.so.1 /lib/libuuid.so.1: symbolic link to `libuuid.so.1.2' [eliot@mcqfes bld]$ file /lib/libuuid.so.1.2 /lib/libuuid.so.1.2: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), stripped Search the Squeak, vm-dev and Pharo archives for info on how to install a 32-bit version. I think it was mentioned within the last month. If your problem is nothing to do with libuuid then I need info like exact OS version, what directories you've installed things in and a gdb backtrace for the crash.
