Re: Squeak 1.3 Solaris link problem

Mike, > It looks as if the solaris VM used to always hard-code the path to > libXext.so.0 > but the 1.3 VM's (both ordinary and JIT) now have to use the search > path somewhere. I don't know what changed (except maybe the build host at my end) -- all the link options are the same as with 1.23. I do, however, have a copy of libXext.so.0 in /usr/lib, which is maybe getting screwed into the binary. Does it still fail if you recompile the Solaris version on your machine? One workaround is to manually screw /usr/openwin/lib into the binary's list of dirs to search at runtime. In GNUmakefile.conf change LIBDIRS= -L/usr/openwin/lib to LIBDIRS= -R/usr/openwin/lib -L/usr/openwin/lib in the sparc-solaris section. If this turns out to be a common problem with the precompiled binary then I'll recompile my copy with the above flag and/or with openwin earlier on my LD_LIBRARY_PATH. (I've _never_ managed to make Solaris "behave" w.r.t. dynamic linking 100% of the time unless I explicitly set LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib:/usr/openwin/lib in my .profile). Hope something in the above helps... Regards, Ian

It looks as if the solaris VM used to always hard-code the path to libXext.so.0 but the 1.3 VM's (both ordinary and JIT) now have to use the search path somewhere. Notice that the first invocation of ldd (on 12% below) shows two entries for the library, one which resolves to /usr/openwin/lib/libXext.so.0 and the other is not found. Doing setenv LD_LIBRARY_PATH /usr/openwin/lib seems to work-around the problem. ____________________________________________ 11% SqueakVM-1.30-sparc-solaris-2.5.1 ld.so.1: SqueakVM-1.30-sparc-solaris-2.5.1: fatal: libXext.so.0: can't open file: errno=2 Killed 12% ldd SqueakVM-1.30-sparc-solaris-2.5.1 libX11.so.4 => /usr/lib/libX11.so.4 libXext.so.0 => (not found) libm.so.1 => /usr/lib/libm.so.1 libsocket.so.1 => /usr/lib/libsocket.so.1 libnsl.so.1 => /usr/lib/libnsl.so.1 libc.so.1 => /usr/lib/libc.so.1 libXext.so.0 => /usr/openwin/lib/libXext.so.0 libdl.so.1 => /usr/lib/libdl.so.1 libw.so.1 => /usr/lib/libw.so.1 libintl.so.1 => /usr/lib/libintl.so.1 libmp.so.1 => /usr/lib/libmp.so.1 13% setenv LD_LIBRARY_PATH /usr/openwin/lib 14% ldd SqueakVM-1.30-sparc-solaris-2.5.1 libX11.so.4 => /usr/openwin/lib/libX11.so.4 libXext.so.0 => /usr/openwin/lib/libXext.so.0 libm.so.1 => /usr/lib/libm.so.1 libsocket.so.1 => /usr/lib/libsocket.so.1 libnsl.so.1 => /usr/lib/libnsl.so.1 libc.so.1 => /usr/lib/libc.so.1 libdl.so.1 => /usr/lib/libdl.so.1 libw.so.1 => /usr/lib/libw.so.1 libintl.so.1 => /usr/lib/libintl.so.1 libmp.so.1 => /usr/lib/libmp.so.1 15% SqueakVM-1.30-sparc-solaris-2.5.1 Could not open the Squeak image file 'squeak.image'.

Re: Squeak... No Sound

> I don't seem to be very lucky with Squeak 1.3, on both Windows 95 > (several ones) and Linux. The Unix ports don't support sound at all. There are so many different ways of doing it on Unix boxes that implementing it would be a nightmare. I once tried to do it using NetAudio, but after failing to make the server run reliably on Linux (and seeing similar reports all over the relevant newgroups) I gave up. If anyone wants to volunteer to implement _portable_ sound for Unix, please press the "reply" button now... ;) Ian

Squeak-1.3 on NetBSD1.3
by Greg Oster 23 Jan '98

23 Jan '98

Hi folks Just letting you know that I've got Squeak v1.3 running on a NetBSD-1.3/i386 box. The changes to the GNUmakefile.conf and sqConfig.h files were pretty minor, and I've included them (the changes) at the end of this message. I'm certainly no Squeak expert, and I've only lightly tested things, but it does look like it's working. All I need now is some time to learn more about it... :-) Later...

Re: various bugs in Windoze ScrollBar Junta
by Sam Adams 23 Jan '98

23 Jan '98

Its sooooo wonderful to have users! John, All of these are problems that crop up when you try to encapsulate another object entirely. One way to fix it is to create a pass thru method of each possible method understood by the encapsulated object. The other way is the powerful but sometimes abused doesNotUnderstand: hack. At OOPSLA'96, Kent Beck had a wonderful button with the caption: Will hack doesNotUnderstand: for Food I don't even need to be very hungry.

Serious Compiler Bug when using to:do:

Squeakers, Steve Burbeck and I have started having problems in methods where we use to:do:.

Sound errors on 68K Macs
by guzdial＠cc.gatech.edu 23 Jan '98

23 Jan '98

Whenever I play a MIDI file on a 68K Mac with Squeak 1.3 (I've tried a Quadra 800 and a PB 190cs), it works for awhile, but near the end (at the end?), I get dumped into Macsbug with "Bus Error at 004E384a signalSemaphoreWithIndex+0042". The disassembly indicates that it's at a "_DisposePtr" I also tried recording a sound on the 190cs. This used to crash 1.23, and it also crashes 1.3. When I click on the Record button in the RecordingControlsMorph there is a long pause, then I get dumped into MacsBug with "Bus Error at 018BA85E FLIPRECORDBUFFERS+0036" -- looks like a MOVEM.L instruction.

The Windoze Junta - StandardSystemView revisited
by Andreas Raab 23 Jan '98

23 Jan '98

Sam, I put a couple of hours into modifying StandardSystemView to display more like something we all love ;-) Below is the result. The new system views have a close box at the upper right, a separate grow and shrink box, and a system menu button which can also be used for closing the view by double clicking ;-) Note that you can turn on and off the new look by executing "NiceSystemView install" or "NiceSystemView unInstall", but this is still a hack - you cannot open new projects after installing. The remaining stuff should work though. If you want to integrate this into your PowerTools please feel free to do so. BTW, I like the combined look of the scroll bars and the system views - now we have to go for the 3d border look on views in general ;-))) Regards, Andreas ---------------------------------------------------------------------------- 'From Squeak 1.3 of Jan 16, 1998 on 22 January 1998 at 11:37:14 pm'!

Squeak 1.3 Release
by Dan Ingalls 23 Jan '98

23 Jan '98

Folks - I wanted to let you all know that the Squeak team is aware of the various problems in the 1.3 release, and that it is our intention, as usual after a major release, to put out a set of fixes or, in this case, more likely to release a follow-up image. In addition to the bugs that have already been posted to this list (and which we plan to address), you should know that there is a bug in BitBlt mode 26, and modes 27-29 are no-ops in the 1.3 VM. We have already fixed these in an internal VM that we are testing. My guess is that we should have this out to you toward the end of next week. In the meantime, we have also implemented a multi-tap reverb instrument, so the music output will be better than ever. We are not certain what causes the problems with Windows sound output, but we'll try to get to the bottom of it before the follow-up release. Also Project windows now show a cleaner thumbnail image of their contents, thus making a very nice iconic organizer for large projects or presentations. Thanks to everyone for their tolerance and especially to those who have posted constructive solutions to the bugs that have shown up in these first few days. - Dan
