Init Error on Precompilation - Ubuntu 20.04 #79

Closed NicoMandel closed 3 years ago

NicoMandel commented 3 years ago

Hi All

I am trying to use libcxxwrap-julia with CXXWrap to compile wrappers for OpenCV. After following the steps of compiling from source into ~/.julia_ws and creating an Overrides.toml file in .julia/artifacts/, I try to use Pkg.add("CxxWrap") and then using CxxWrap. The package then responds with the following output:

julia> using CxxWrap

System:

The output of strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBC shows me that GLIBXX_3.4.26 is present. Any help would be greatly appreciated.

Hi @NicoMandel ,

Have you tried it with Julia@v1.6.0-rc1?

NicoMandel commented 3 years ago

Hi

no, I haven't. Is this recommended? Is there an option to switch to an older tag of ibcxxwrap-julia? I actually manually symlinked the so file in my julia directory to my system one and that seemed to work

I'm not sure. I just hit the same problem recently and I found it was fixed with Julia@v1.6.0-rc1

I actually manually symlinked the so file in my julia directory to my system one and that seemed to work

Yes, this is also a valid manual solution.

Going to close this, removing /opt/julia-1.5.3/bin/../lib/julia/libstdc++.so.6 or symlinking it is one valid solution, the other solution is to compile Julia from source.
