Successfully built VM on OS X 10.11.6 (15G18013)
by Tim Johnson 15 Mar '18

15 Mar '18

Hi Eliot, I’ve successfully built the VM on the OS X revision described in the subject line. (Hooray!) It was indeed easy and not scary or intimidating at all. Steps taken: 1. googled "cog blog squeak” 2. visited "compiling the VM" at http://www.mirandabanda.org/cogblog/compiling-the-vm/ (#2 note: http://wiki.squeak.org/squeak/6202 was not immediately helpful as far as compiling the VM -- maybe could contain link to the above) 3. followed instructions from “compiling the VM": % cd ~/src % git clone http://www.github.com/OpenSmalltalk/opensmalltalk-vm oscogvm % cd oscogvm 4. opened & began following README.md (Eliot Miranda / August 2017) misty:src tcj$ cd oscogvm/ misty:oscogvm tcj$ ./scripts/updateSCCSVersions No stash found. misty:oscogvm tcj$ cd build.macos32x86 5. opened & began following HowToBuild 6. followed code-signing instructions in step 1 decided on self-signed certificate created in keychain utility per: https://developer.apple.com/library/content/documentation/Security/Conceptu… added export SIGNING_IDENTITY="tcj Code Signing" to ~/.bash_profile sourced ~/.bash_profile 7. continued to follow instructions: % cd squeak.cog.spur % ./mvm -A entered keychain password for code-signing 3 times, a’la note in README.md #1a dutifully ignored various frightening warnings about deprecations etc. 8. ka-blang! success! open ./Squeak.app Couldn’t have any been clearer. One future direction I may explore: adding older SDKs a’la the instructions in “HowToBuild”. I know that an old way to add SDKs would have involved opening an Xcode project file and adding “frameworks" via the Xcode GUI. It looks like the modern build system seems to not use `xcodebuild` or Xcode project files anymore. I also want to make sure that the Info.plist in the app bundle reflects the lowest SDK used; right now it lists 10.9.0 and I’m not sure if this hard-coded or generated. One place I got curious because I’m on a sort-of holiday, but decided to walk slowly away from: the old (e.g. Squeak Cog 4.0.3248) Mac OS VM’s “Squeak DoIt” entry in OS X’s “Services” menu, which is now gone. It used to live in Info.plist, now it doesn’t. It seemed to be rather clumsy before (launching a new VM rather than communicating with an existing one) and may have involved an extended clipboard plugin so I’ve decided this is a bee’s nest I will refrain from poking. I’ll stop considering how far Squeak can dive into NSPasteboard. It’s not important. Just a whim. On with my day. Thanks, Tim

Linux Travis VM builds not uploading
by Clément Bera 13 Mar '18

13 Mar '18

Hi all, it seems the linux vm builds do not upload the build artifact to the websites due to this error: ./filter-exec.sh: 15: ./filter-exec.sh: [[: not found ./filter-exec.sh: 15: ./filter-exec.sh: [[: not found Based on google, it seems it does execute the file with bash. I added #!/bin/bash <https://github.com/OpenSmalltalk/opensmalltalk-vm/commit/11a899a4e3ef135a43…> at the beginning of the file like the other bash files but it does not solve the problem. Any idea on how to fix this ? First time I get the win build working before the linux build :-) Thanks -- Clément Béra https://clementbera.github.io/ https://clementbera.wordpress.com/ Bâtiment B 40, avenue Halley 59650 Villeneuve d'Ascq

Pharo VM crash in bootstrap with Inconsistency detected by ld.so
by Alistair Grant 13 Mar '18

13 Mar '18

Hi Tobias, Esteban and Fabio, Attempting to bootstrap the image with Pharo 7.0 VMs newer than 30 Jan are failing with: + vm/pharo Pharo7.0-32bit-eabf524.image eval --save "Metacello new baseline: 'Tonel';repository: 'github://pharo-vcs/tonel:v1.0.5';onWarning: [ :e | Error signal: e messageText in: e signalerContext ]; load: 'core'" ... ...finished baselinelinear load : linear load : baseline [BaselineOfTonel] load : MonticelloTonel-Core-cypress.1 load : MonticelloTonel-FileSystem-cypress.1 Inconsistency detected by ld.so: dl-close.c: 811: _dl_close: Assertion `map->l_init_called' failed! VMs prior to this succeed (e.g. the current stable vm70). The error is happening after the image is saved, so it is actually possible to continue and successfully bootstrap the image, but obviously that is not solving the core issue.

Also, soft-fallback for later features such as host name verification is hard. When we statically link, we might lack behind the OS, the binaries are bigger, and the legal situation is less clear. So we now support not linking at all but rather lookup all necessary functions/symbols at runtime. This can be disabled with SQSSL_OPENSSL_LINKED which effectively results in the dynamically-linked behavior. (This is preferable for platform builds, eg, debs and rpms) I'm struggling to figure this one out at the moment and am hoping that one of you might recognise something to help track it down... P.S. I also tried compiling with -DSQSSL_OPENSSL_LINKED, but that produced compiler errors. Help :-) Alistair

For the Cog VMs the Bible (actually the implementation) is StackInterpreter class>>#initializePrimitiveTable in the VMMaker.oscog package in source.squeak.org/VMMaker.

Deconstruction: ```C ((void*(*)())NULL) ``` - `NULL` is the part that evaluates to "not true" in the expression to the if - `(*)` makes it a function pointer - `void*` returning anything (most importantly, something assignable to anything) - `()` not specifiying what kind of arguments will come in. All this should be standard-compliant
