Problem with multi-threads

[zhaoli-IHEP]

We found that the default version of SymEngine.jl in Julia1.3.1 does not support multi-thread programming. And we found #166 claims SymEngineBuilder could help. However, it can be seen in build_tarballs.jl that it downloads SymEngine.jl v0.5.0 to build. Does it mean the multi-threads is only available for v0.5.0? And even though we confront the error to use build_tarballs.jl

Do we have different solution in the current version?

Can you try #186 ?

Can you try #186 ?

Do you mean that I have to manually change Project.toml in SymEngine.jl source code and build again? Then it will support multi-threads?

Try doing pkg> add SymEngine#master in Julia 1.3

Try doing pkg> add SymEngine#master in Julia 1.3

Thank you for this interesting information. However, it seems version conflict appears.

(v1.3) pkg> add SymEngine#master

Can you try again? I just merged a PR to master.

Thank you so much. Now it works perfectly.
So just for understanding, this will use the github version of SymEngine instead of the release version, is it right?
And in the future for update, is it just to use pkg> update SymEngine to fetch latest github version?
Also can we just use pkg> add SymEngine to switch back to release version?

0.8.0 version has this now
