Error building Cxx #483

Closed hb2hb closed 3 years ago

I try to use Cxx

Version 1.4.2 (2020-05-23) 
Fedora 32 build 

julia> using Pkg

I created /usr/lib64/julia/libLLVM-8.0.1.s0 as symbolic link to /usr/lib64/julia/libLLVM-8jl.so 

[henry@devpc julia]$ ls -la /usr/lib64/julia/*LLVM* 
lrwxrwxrwx 1 root root       31 сен 30 16:50 /usr/lib64/julia/libLLVM-8.0.0.s0 -> /usr/lib64/julia/libLLVM-8jl.so

lrwxrwxrwx 1 root root       14 июн 14 23:21 /usr/lib64/julia/libLLVM.so -> /usr/lib64/julia/libLLVM-8jl.so

Where to put the symbolic link to libLLVM-8jl.so as libLLVM-8.0.1.s0 so that it will be visible by julia builder ?

Thanks a lot in advance!

In case you'd like to do a source build with Julia 1.4, there is an unfinished PR for that.
