FYI, Spoon simulates on Mac/win32/Linux
by Craig Latta 29 May '11

Hi-- Just FYI, Spoon (VMMaker-dtl.237 plus support for proxies, method reporting/imprinting and stale method removal) runs in the simulator on MacOS, win32 and Linux, although "pluginClass" in VMPluginCodeGenerator>>isTypePointerToStruct: is still undeclared. -C -- Craig Latta www.netjam.org/resume +31 06 2757 7177 + 1 415 287 3547

Stupidifying FFI/library loading mechanism
by Igor Stasenko 27 May '11

27 May '11

Hello, i am fed up seeing the messages like "FFI can't find a library" or "VM can't find my plugin". I think we should trash too clever intrinsic library lookup mechanism and provide a simple primitive, which attempts to load a library by given file name & path and if it fails, give an extended response, why: - library found, but can't be loaded (because it 64bit while you running 32 bit), or it can't be found and so on. It should be up to the user to find and load the library first, and only after you obtained a valid library handle, attempt to do FFI calls. IMO, same should be done to plugin loading mechanism. VM should give you the paths: - what is the current directory - what is the directory where VM located then user code could attempt to load external plugin by specifying one of these paths or any other to the library which representing plugin. And only after he knows that library successfully loaded, he could attempt to use its primitives (or do FFI calls). The approach is simple: - first you making sure that you loaded external module/plugin, then you start using it. And it is your responsibility to make sure you loaded it, not VM's. This could be done at image startup or at code entry point, or even inside a generic code which handling a primitive failure. VM should behave like a stupid idiot: - if module with name, which specified in primitive pragma <primitive: 'foo' module: 'bar' > not registered already in internal list of VM's modules, it should fail unconditionally without even trying to load external library. Even for internal plugins: A user code can handle this error and instruct VM explicitly to load & initialize internal plugin, but not implicitly like currently VM does for internal and external plugins. If we put a module loading mechanism at image side, it will give us much more flexibility, and all future/potential problems with it could be fixed there without touching VM code anymore. I know that it means quite a lot of work (some named primitives even assume that they never fail). But i think it is worth it. Because if it will stay like that, we will always have issues with it, over and over again. -- Best regards, Igor Stasenko AKA sig.

I have no idea. Maybe someone in the VM mailing list can help you.

working directory under Mac OS X
by Eliot Miranda 26 May '11

26 May '11

Hi Andreas, Matthew, John, (Hi All), I'm getting my house in order, merging the Newspeak VM into the OSCog platforms hierarchy. One big difference between trunk vms (and Newspeak) and Qwaq VMs on Mac OS X is that in the Qwaq VM there is an early chdir to the directory containing the .app, whereas in the non-Qwaq VMs the directory is left as is. If you look at http://squeakvm.org/svn/squeak/trunk/platforms/Mac OS/vm/sqMacMain.c you'll see that this chdir has been commented-out, so there was a point when it was in standard VMs. Andreas, Matthew, do you think the Qwaq behavour is important to preserve? John, what's the history of this? Should I even bother trying to maintain the Qwaq behaviour and instead disable it in all builds (Qwaq, OSCog, Newspeak)? best, Eliot

FFI is not finding libraries on Ubuntu 11.04
by Matthew Fulmer 26 May '11

26 May '11

In the 4.4.7 interpreter unix vm, under ubuntu 11.04, I try to run OpenGL like so: OpenGL example It gives an ffi error (Unable to find function address), and strace reveals the following activity: access("/etc/ld.so.nohwcap", F_OK) = -1 ENOENT (No such file or directory) open("/lib/i386-linux-gnu/GL", O_RDONLY) = -1 ENOENT (No such file or directory) open("/usr/lib/i386-linux-gnu/GL", O_RDONLY) = -1 ENOENT (No such file or directory) open("/lib/GL", O_RDONLY) = -1 ENOENT (No such file or directory) open("/usr/lib/sse2/GL", O_RDONLY) = -1 ENOENT (No such file or directory) open("/usr/lib/GL", O_RDONLY) = -1 ENOENT (No such file or directory) The library is actually at /usr/lib/mesa/libGL.so.1. I have no idea why ffi is apparently looking for a file named GL rather than libGL.so* A simpler test is perhaps X11Display new which is included as an example in the FFI Unix Examples package, and calls the external function X11Display class >> XOpenDisplay: displayName "X11Display XOpenDisplay: nil" <cdecl: X11Display* 'XOpenDisplay' (char*) module:'X11'> ^self externalCallFailed It also results in a series of calls to bogus files: access("/etc/ld.so.nohwcap", F_OK) = -1 ENOENT (No such file or directory) open("/lib/i386-linux-gnu/X11", O_RDONLY) = -1 ENOENT (No such file or directory) open("/usr/lib/i386-linux-gnu/X11", O_RDONLY) = -1 ENOENT (No such file or directory) open("/lib/X11", O_RDONLY) = -1 ENOENT (No such file or directory) open("/usr/lib/sse2/X11", O_RDONLY) = -1 ENOENT (No such file or directory) open("/usr/lib/X11", O_RDONLY) = 8 The library is actually at /usr/lib/i386-linux-gnu/libX11.so.6 , which is at least in whatever search path FFI seems to be using. It may have found the library had it been looking for the correct filename My ld config files are as follows: === /etc/ld.so.conf === include /etc/ld.so.conf.d/*.conf === /etc/ld.so.conf.d/GL.conf (symlink to /etc/alternatives/gl_conf) === /usr/lib/mesa === /etc/ld.so.conf.d/i686-linux-gnu.conf === # Multiarch support /lib/i386-linux-gnu /usr/lib/i386-linux-gnu /lib/i686-linux-gnu /usr/lib/i686-linux-gnu === /etc/ld.so.conf.d/libasound2.conf === /usr/lib/alsa-lib === /etc/ld.so.conf.d/libc.conf === # libc default configuration /usr/local/lib There is no such file /etc/ld.so.nohwcap I know this was working in ubuntu 10.04, but I erased that system and reinstalled ubuntu 11.04, so I can't give a working strace example. For now, I worked around the issue by making a symlink from /usr/lib/GL to /usr/lib/mesa/libGL.so.6. This allowed me to run Cobalt For comparison, the same commands give the following strace on cog vm 2378: OpenGL example (Error: External module not found): stat64("./bin-cog/i686-pc-linux-gnu",

the error seems to be different on interpreter (Unable to find function address) vs cog (External module not found)

strange display scaling on iPhone
by Craig Latta 26 May '11

26 May '11

Hi-- When I run the interpreter VM on an iPhone (built from an SVN checkout earlier today), I get a strange display scaling effect, as shown in the attached picture (hopefully the attachment comes through). This is on an iPhone4... is there some hardwired display attributes thing I need to change? Anyone know what's going on? thanks, -C -- Craig Latta www.netjam.org/resume +31 06 2757 7177 + 1 415 287 3547

MacVM and VNC
by Stefan Marr 26 May '11

26 May '11

Hi Esteban: I have another problem with the MacVM. (5.8b12) I get the following error on the command line, and do not get any output in the opened window: 2011-05-26 01:11:02.747 Squeak[2814:903] invalid pixel format 2011-05-26 01:11:02.748 Squeak[2814:903] invalid context 2011-05-26 01:11:02.748 Squeak[2814:903] invalid pixel format Since I have never seen that before, I suspect that it is an interaction with the VNC display. I don't have physical access to the machine and use it via standard OSX remote desktop. This problem exists also for the 5.7.4.1 VM, but Eliot's Cog.app builds do not seem to have that problem.
