Julia 1.7 does not start on macOS Monterey

[matthieugomez]

I have just updated my Mac to Monterey and Julia 1.7 won’t start anymore. Calling it in the terminal gives

fatal: error thrown and no exception handler available.

Julia 1.6 still works without problem.

original issue on discourse: https://discourse.julialang.org/t/cannot-start-julia-1-7-rc2/70629

another issue discussing the same problem:
https://discourse.julialang.org/t/is-julia-compatible-with-mac-os-monterey/70588/12

Just for reference, I have Xcode version 13.1 and Perl version 5.30.3, and Intel x86

Can you confirm with

$ DYLD_PRINT_LIBRARIES=YES julia -e0 2>&1 | grep pcre

which PCRE library gets loaded? Just in case the root cause is similar to that fixed by #42721 (namely that dyld under Monterey loads the system library instead of the one packaged with Julia).

[matthieugomez]

Thanks for your help. I get ``` →DYLD_PRINT_LIBRARIES=YES /Applications/Julia-1.7.app/Contents/Resources/julia/bin/julia -e0 2>&1 | grep pcre 15:03 dyld[44331]: <33D0E13B-557D-3C47-A894-BC062F3BF6EA> /usr/local/Cellar/pcre2/10.33/lib/libpcre2-8.0.dylib compile at ./pcre.jl:155 ``` With Julia 1.6 I get ``` →DYLD_PRINT_LIBRARIES=YES /Applications/Julia-1.6.app/Contents/Resources/julia/bin/julia -e0 2>&1 | grep pcre 15:03 dyld[44251]: <20CE2416-6B33-313F-8B31-1956C0289A2D> /Applications/Julia-1.6.app/Contents/Resources/julia/lib/julia/libpcre2-8.0.dylib ```

[mgkuhn]

This looks indeed much like the problem that #42721 is meant to fix, which has already been merged into master and has been back-ported to 1.7-rc3. Does the current "Nightly" build still have this problem?

[matthieugomez]

I just downloaded the nightly build but it still does not work. I get the same message as with 1.7. Moreover, your command returns the same thing too: ``` →DYLD_PRINT_LIBRARIES=YES /Applications/Julia-1.8.app/Contents/Resources/julia/bin/julia -e0 2>&1 | grep pcre 15:04 dyld[45168]: <33D0E13B-557D-3C47-A894-BC062F3BF6EA> /usr/local/Cellar/pcre2/10.33/lib/libpcre2-8.0.dylib compile at ./pcre.jl:155 ```

[KristofferC]

What commit is that build on?

[matthieugomez]

The release called “nightly release” currently on the Julia webpage. Not sure which commit it corresponds to since Julia never display the startup message.

You could try

/Applications/Julia-1.8.app/Contents/Resources/julia/bin/julia -e "println(Base.GIT_VERSION_INFO.commit_short)"

or

/Applications/Julia-1.8.app/Contents/Resources/julia/bin/julia -e "println(VERSION)"

[vchuravy]

Or cat /Applications/Julia-1.8.app/Contents/Resources/julia/share/julia/base/version_git.jl

[matthieugomez]

Thanks, I get ``` →cat /Applications/Julia-1.8.app/Contents/Resources/julia/share/julia/base/version_git.jl 19:05 const GIT_VERSION_INFO = GitVersionInfo( "86f656d414463ed20b28aa6138dc3e3917b77a84", "86f656d414", "master", 849, "2021-10-31 12:23 UTC", false, 0, 1635682986. ) ```

[IanButterworth]

Looks like that includes #42721

For the record I'm on Monterey (x86) and 1.6.3 1.7.0-rc2 and master all work

[mgkuhn]

@IanButterworth You may not have done a brew install pcre2 (or installed something with that dependency), and therefore wouldn't have a file /usr/local/Cellar/pcre2/10.*/lib/libpcre2-8.0.dylib in place, which appears to be accidentally loaded here.

Also: in any report about macOS Big Sur or newer, please always state now the architecture (Intel or ARM), as these can behave quite differently, and almost certainly involve many different OS code paths and bugs^Wundocumented behaviours.

[ararslan]

As a data point, the official Julia v1.7.0-rc2 binary starts for me on macOS Monterey with an Intel processor but it loads a bunch of stuff from Homebrew, not limited to PCRE:
