Hi, Working on Julia packages, see [1], I note that the Julia build system is not reproducible. It is probably linked to this issue:
<http://issues.guix.gnu.org/issue/22304> Concretely, let pick the package ’julia-adapt’: --8<---------------cut here---------------start------------->8--- $ diff -r --no-dereference /gnu/store/3rvnp4q49k32yrv9iaxpyj2xpk8x3bi7-julia-adapt-3.1.1{,-check} Binary files /gnu/store/3rvnp4q49k32yrv9iaxpyj2xpk8x3bi7-julia-adapt-3.1.1/share/julia/compiled/v1.5/Adapt/rUIgN_JghfZ.ji and /gnu/store/3rvnp4q49k32yrv9iaxpyj2xpk8x3bi7-julia-adapt-3.1.1-check/share/julia/compiled/v1.5/Adapt/rUIgN_JghfZ.ji differ --8<---------------cut here---------------end--------------->8--- I do not know if it is fixed by upstream with the recent release julia@1.6. Probably not. Any help to remove this unreproducibility is welcome. :-) Cheers, simon 1: <http://issues.guix.gnu.org/issue/47350>
