Hi All, I try to compile v1.4.0 using gcc 6.4.0, get following error:

error during bootstrap:  
LoadError(“sysimg.jl”, 3, LoadError(“Base.jl”, 198, LoadError(“version.jl”, 240, ArgumentError("invalid version string: "))))  
VersionNumber at ./version.jl:111

Can someone help me to find out the reason? thanks!

The error seems to be from [https://github.com/JuliaLang/julia/blob/b8e9a9ecc62ab49003bd4f1834771bdeb8cb1aa2/base/version.jl#L240-L246](https://github.com/JuliaLang/julia/blob/b8e9a9ecc62ab49003bd4f1834771bdeb8cb1aa2/base/version.jl#L240-L246). Can you check the `libllvm_version_string` entry in `base/build_h.jl`?

Hi fredrikekre, thanks for your reply. I checked `libllvm_version_string` entry in `base/build_h.jl` it empty: libllvm\_version\_string = “” How to fix it? Thanks!

I guess something goes wrong [here](https://github.com/JuliaLang/julia/blob/b0f3403f0607f5666ea5cc432a1db83849a08975/Make.inc#L910-L924) then? What does

```julia
$ make print-LLVM_CONFIG_HOST
LLVM_CONFIG_HOST=/home/fredrik/julia-master/usr/tools/llvm-config

$ /home/fredrik/julia-master/usr/tools/llvm-config --version
9.0.1jl

```

return for you?  
Have you made any settings w.r.t. LLVM?

It shows: /lib64/libstdc++.so.6: version `GLIBCXX\_3.4.22’ not found. I have to upgrade libstdc++.so
