Raw mouse events in the Squeak VM?
by Phil B 24 Apr '19

24 Apr '19

I recall a discussion about this a while back but don't recall if it applied to the Squeak VM or if it was ever implemented. Two things I'm looking for: 1) The ability to get 'uncooked' mouse button events which don't remap modifiers to alternate button events (i.e. ctl-click and alt-click) 2) More generally, the ability to get raw mouse movement/button/scroll wheel events distinct from keyboard events. Are either of these currently possible or would I need to build a custom VM to support? Thanks, Phil

Squeak trunk patch - override hard-coded paths
by K K Subbu 24 Apr '19

24 Apr '19

Hi, The current Makefile.example in squeak trunk uses a hard-coded paths for install which requires sudo permissions. I have attached a SVN patch for this file to override the path for those who don't have sudo permissions. With this patch, one can do the builds in any directory and install in any path. Doing builds in tmpfs is much faster than on SSD or hard disk. $ squeaksvn=`pwd` $ bld=$(mktemp -d /tmp/build.XXX) $ target=$bld/target $ cd $bld $ cp $squeaksvn/platforms/unix/cmake/Makefile.example Makefile $ make O=$target P=$squeaksvn/platforms S=$squeaksvn/src $ make install $ $target/bin/squeak $TESTIMAGE $ rm -rf $bld $target Regards ..

compiling Objective-C++ (.mm) files with clang++ on MacOS
by Eliot Miranda 23 Apr '19

23 Apr '19

Hi All, anyone know if there's a special -x argument for clang++ when compiling .mm files? I'm suffering from a conflict between the boost C++ libraries use of noexcept and Objective-C's use of noexcept as a keyword. It may be that I'm invoking clang++ wrongly. But if I use either clang++ -x objc or clang++ -x objc++ both are rejected "language not recognized". I can't find a list of acceptable language names (the man page just says -x <language> Treat subsequent input files as having type <language> _,,,^..^,,,_ best, Eliot

MacOS Code Signing bundle parts
by Ben Coman 19 Apr '19

19 Apr '19

I just bumped into the following article... https://developer.apple.com/library/archive/documentation/Security/Conceptu… and the section "Ensuring Proper Code Signatures for Nested Code" made me remember some reports of corrupted signatures when installing Pharo/Squeak. Particularly interesting were... * "Starting in macOS 10.9, the code signing tool records nested code." * "Store ...shell... script files and other non-Mach-O executables in your app's Contents/Resources directory. While it's possible to sign such executables and store them in Contents/MacOS, this is not recommended. This is because code signing uses extended attributes to store signatures in non-Mach-O executables such as script files. If the extended attributes are lost, the program's signature will be broken. Many file transfer techniques do not preserve extended attributes, nor are they preserved when uploading to the Mac App Store." I'm not familiar with the bundle arrangement and don't have a Mac running to check this, so pinging those more intimate with the MacOS bundle to advise whether the article may impacts us. cheers -ben

Any experts on using path in app bundles willing to help me?
by Eliot Miranda 19 Apr '19

Hi All, I have a plugin dependent on several support libraries that may be shared with other plugins. So I want the support libraries in a common place (TheVm.app/Contents/Frameworks) while the plugins themselves are bundles in TheVM.app/Contents/Resources. In allowing one to install plugin support libraries in TheVM.app/Contents/Frameworks I have to use the linker's -rpath feature to specify where dlopen may find the search libraries. The question i don't see an answer to in Apple's documentation is whether one uses -rpath when linking the plugin, or when linking the VM into which the plugin will be loaded, or both. Anybody ever done this and know definitively what to do? _,,,^..^,,,_ best, Eliot
