Cannot precompile in Julia 1.11.0-DEV.868 (2023-11-08) Commit f31cd8ad2f

[laurentbartholdi]

I updated Julia a few days ago from its github source; and BAM CxxWrap doesn't work anymore. The message, after updating CxxWrap to #main or to the latest release:

The same error can be seen in the GitHub CI on master: https://github.com/JuliaInterop/CxxWrap.jl/actions/runs/6724789547/job/18277808733#step:6:119
The linux error is slightly more helpful:

julia: symbol lookup error: libcxxwrap_julia.so: undefined symbol: jl_arrayset, version JL_LIBJULIA_1.11

This should get fixed by JuliaInterop/libcxxwrap-julia#137 although I have not tested this on macOS.

TADA, it works now with a home compile!

FWIW:

• macOS has changed all the debugging infos; DYLD_PRINT_LIBRARIES=1 julia -e 'using CxxWrap' was useful to find out which library was loaded
• I couldn't get CxxWrap to use the "override" libraries as indicated in the documentation; so I just put a quick-and-dirty "cd override; ln -sf pwd ~/.julia/artifacts/1f21436ed601f5e0111b57dfae2407890f4bbc4b"

I have merged JuliaInterop/libcxxwrap-julia#137, so I think the current libcxxwrap-julia main branch is a good candidate for a release and rebuild of the JLL. I guess this will break JLL linked against older versions of libcxxwrap-julia?

I tried this locally with julia 1.9 and it seems to work fine without a rebuild:
I used the jl_array branch to locally build a new jll for x86_64-linux-gnu-cxx11-julia_version+1.9.0 and the Polymake.jl tests run fine with the previously released version of libpolymake_julia_jll (I tried CxxWrap.jl release and main branch).
Edit: Same for julia 1.6.

But for julia-nightly we do seem to need rebuilds of dependent jlls, otherwise I get crashes.
