[OpenSmalltalk/opensmalltalk-vm] libgit build fails because of libssl and libcrypto (#210)
by Javier Pimas 04 Dec '19

04 Dec '19

on /build.linux32x86/pharo.cog.spur/build I run ./mvm and get make[3]: *** No rule to make target '/usr/lib/i386-linux-gnu/libssl.so', needed by 'libgit2.so.0.25.1'. Stop. I worked around it by running sudo ln -s /lib/i386-linux-gnu/libssl.so.1.0.0 /usr/lib/i386-linux-gnu/libssl.so but shouldn't be necessary as libssl is downloaded and built by the script. The same happens with libcrypto -- You are receiving this because you are subscribed to this thread.

[OpenSmalltalk/opensmalltalk-vm] Crash in interpret (?) (#402)

[OpenSmalltalk/opensmalltalk-vm] 32-bit libB3DAcceleratorPlugin.dylib fails to link; 32-bit Squeak B3DAcceleratorPlugin links against metal. (#385)
by Eliot Miranda 22 Nov '19

Seems to be something strange with the B3DAcceleratorPlugin on 32-bit macos. The pharo libB3DAcceleratorPlugin.dylib fails to link missing: createOpenGLTextureLayerHandle destroyOpenGLTextureLayerHandle getMainWindowOpenGLContext setOpenGLTextureLayerContent The Squeak one links, but apparently against Metal, which isn't going to work since Metal is 64-bit only (or so I've been told). -- You are receiving this because you are subscribed to this thread.

[OpenSmalltalk/opensmalltalk-vm] Image buffer corruption when running build.macos64x64 targets (#392)
by Gene Ragan 22 Nov '19

Building from the latest sources on the Cog branch, I see the attached image when loading various images using various OSX builds. I have tried the 64-bit Pharo, Squeak and newspeak builds with their associated images. I see some variation of the attached image below. If I rollback the source to the 201901172323 tag, I am able to build and load an image and see the window as expected. <img width="811" alt="Screen Shot 2019-04-23 at 6 47 51 PM" src="https://user-images.githubusercontent.com/32800969/56627814-3fea6280-65fc-1…"> -- You are receiving this because you are subscribed to this thread.

It seems that after ba7bb9557 a seqfault was introduced to the 64bit Linux VM. With no image file the VM happily produces output. When providing an image file it immediately segfaults regardless of whether a display is provided or whether it runs headless. -- You are receiving this because you are subscribed to this thread.

Problem in newspeak cogit code generation
by Nicolas Cellier 09 Nov '19

09 Nov '19

Hi all, I see what looks like a big problem in those files: https://raw.githubusercontent.com/OpenSmalltalk/opensmalltalk-vm/Cog/nsspur… https://raw.githubusercontent.com/OpenSmalltalk/opensmalltalk-vm/Cog/nsspur… The generated code for genSendDirectedSuper:numArgs: is bogus. the 3 instance variables - directedSendUsesBinding - directedSuperSendTrampolines - directedSuperBindingSendTrampolines have been translated into local (thus uninitialized) variables... How can this possibly work? Is it related to the CI failures?

[OpenSmalltalk/opensmalltalk-vm] Remove macRoman translation of keyboard keyValue in Win32 VM (#401)
by Nicolas Cellier 04 Nov '19

04 Nov '19

There is code that transforms the presumably latin-1 key value into approximately MacRoman encoding in platforms/win32/vm/sqWin32Window.c I let the archeologists debate if this code dates from Jurassic period or more distant paleozoic era, all I know is that we pay for what we don't buy... Thus I propose to entirely remove that piece of code and disentangle a bit the spaghetti keyboard handling. We indeed do not need this extra level of complexity anymore, images do not use macRoman encoding for a long time On the contrary, images have to undo the translation by sending `macToSqueak` message in various subclasses of `KeyboardInputInterpreter`. For the transition period, old images running on new VMs, or new images running on old VMs, might encounter a few hickups while interpreting non ASCII characters in case of exotic `KeyboardInputInterpreter`. That won't be the case of main `UTF32InputInterpreter` since it mostly uses the utf32 code passed through `eventBuffer sixth` position rather than keyValue passed thru `eventBuffer third`, except for some CTRL+key for which the keyValue is more-than-often < 128, and thus unaffcted by the proposed change. -- You are receiving this because you are subscribed to this thread.
