RE: Linux vm default plugins directory
by Schwab,Wilhelm K 01 Sep '10

01 Sep '10

Bert, Eliot, FWIW, I have had terrible results with LD_LIBRARY_PATH on Ubuntu - maybe I'm just missing something. I probably should let the squeak script handle it, but it seems silly to use a script to call a script, so I've typically gone straight to the vm; that appears to be getting harder to do with time. About plugins not loading, my big point is that we should not have to guess about what is or is not happening. The vm does not provide enough information to reliably fix problems.

Here's the script I use at Teleplace The current "squeak" script fills in the plugins path, so there is no need to fiddle with LD_LIBRARY_PATH. http://squeakvm.org/svn/squeak/trunk/platforms/unix/cmake/squeak.in However, I occasionally too see a plugin that inexplicably does not want to load. - Bert -

Serial ports on Linux
by Schwab,Wilhelm K 01 Sep '10

01 Sep '10

I have been able to do serial I/O on Windows, but not Linux. Running in a terminal to capture output yields "Error while saving old state" while trying to open just about any number or name I can think of (including 0 and /dev/ttyS0), but the open method gives no indication that there is a problem; it returns a perfectly valid looking serial port with the #port set to whatever it was given. Subsequent reads fail, and are probably a bit more honest about what is happening: "Error while reading: serial port is not open." I am not sure whether that is always the case, but it certainly is on this machine when I try /dev/ttyUSB0, which does not exist here. Any ideas? Bill
