Hi list, after having tried to update with the new upload, ConTEXt doesn't run anymore. According to the output the new version requires a more recent system. I still use macOS 10.13.6 (High Sierra). This is what I get: ================= context TestCode.tex dyld: lazy symbol binding failed: Symbol not found: ____chkstk_darwin Referenced from: /Applications/TeX/context-osx-64/tex/texmf-osx-64/bin/context (which was built for Mac OS X 12.7) Expected in: /usr/lib/libSystem.B.dylib dyld: Symbol not found: ____chkstk_darwin Referenced from: /Applications/TeX/context-osx-64/tex/texmf-osx-64/bin/context (which was built for Mac OS X 12.7) Expected in: /usr/lib/libSystem.B.dylib /bin/bash: line 2: 1569 Abort trap: 6 context TestCode.tex context TestCode.tex dyld: lazy symbol binding failed: Symbol not found: ____chkstk_darwin Referenced from: /Applications/TeX/context-osx-64/tex/texmf-osx-64/bin/context (which was built for Mac OS X 12.7) Expected in: /usr/lib/libSystem.B.dylib dyld: Symbol not found: ____chkstk_darwin Referenced from: /Applications/TeX/context-osx-64/tex/texmf-osx-64/bin/context (which was built for Mac OS X 12.7) Expected in: /usr/lib/libSystem.B.dylib /bin/bash: line 4: 1579 Abort trap: 6 context TestCode.tex =================== Trying to install again, I get: ==================== sh install.sh dyld: lazy symbol binding failed: Symbol not found: ____chkstk_darwin Referenced from: /Applications/TeX/context-osx-64/bin/mtxrun (which was built for Mac OS X 12.7) Expected in: /usr/lib/libSystem.B.dylib dyld: Symbol not found: ____chkstk_darwin Referenced from: /Applications/TeX/context-osx-64/bin/mtxrun (which was built for Mac OS X 12.7) Expected in: /usr/lib/libSystem.B.dylib install.sh: line 105: 1693 Abort trap: 6 $PWD/bin/mtxrun --script ./bin/mtx-install.lua --update --server="$LMTXSERVER" --instance="$LMTXINSTANCE" --platform="$PLATFORM" --erase --extras="$LMTXEXTRAS" ====================== What can I do?
