Hi, Working on Manjaro Linux, GCC 8, Julia 1.0 installed with the official Manjaro repos. I try to do some work with 1.0… Of course, none of my codes work (has been wrote in 0.5) :frowning: I can fix it, but the problem is I can’t even have a proper working Julia installation anymore :frowning: W…

[image] charlesll: I know it is probably related to this post , but I do not really understand the solution? Should I install Julia from the binary? Do anyone has any suggestion? Yes, if you download the binary from Download Julia it should work.

Building on Arch Linux worked for me following the advice in this comment: https://github.com/JuliaLinearAlgebra/Arpack.jl/issues/5#issuecomment-400522447 ,

Not directly related, but since you mentioned you have to port code from 0.5: [image] PSA: use Julia 0.7 if you are upgrading Announcements A lot of people are posting issues where their old code doesn’t work anymore on 1.0 because some function has been renamed or remove…

Those Manjaro repos are likely just the Arch Linux repos. I’m not sure why they are recompiled, Arch policy should dictate not changing upstream packages unless you have to. Just downloading the default Julia binaries and running them from /opt works for me.

Thanks for the replies!! I’m gonna remove official Julia, and install Julia 0.7 from binaries in this case! This will leave me time to adapt my code to 1.0 also as suggested by @Sukera

Both 0.7 and 1.0 are official and released builds - the difference between the two is that 0.7 has deprecation warnings for removed functions and 1.0 does not. In that respect, 0.7 is intended to be used for your precise usecase - porting old code to the newest version. Once it works on 0.7, it shou…

Makes sense, I will transmit the problem on Manjaro’s forum. @Raf Manjaro does not use Arch repos directly, but their own repo.

Hum, but I still can’t have my code running or my packages installing… They require PyCall that does not build in 0.7 :disappointed_relieved: I can’t spend hours dealing with such issues, I need productivity at this stage… => it was faster for me to re-code everything in Python… :frowning:

What? PyCall builds just fine in 0.7.

Apparently no. I got this error, and I can’t figure what is creating it… Building PyCall → `~/.julia/packages/PyCall/rUul9/deps/build.log` ┌ Error: Error building `PyCall`: │ ┌ Warning: Deprecated syntax `(init === nothing) ? if (dims === nothing) │ │ Base.reduce │ │ op │ │ a │ │ else …

Works fine for me on Arch and 0.7 with “PyCall” => v"1.18.2" Maybe check your package version? that looks like an older version with the depreciation warnings?
