“Failed to clean up temporary path” on exit

[essandess]

I’m the julia maintainer for MacPorts.

Version 1.12.1 throws the error below on exit, and goes into an infinite loop that I’m unable to kill unless I delete the binary (!). This is on a macOS 25 arm64 box.

The install is compiled from source using a clean make && make install sequence.

I confirm that setting make JULIA_PRECOMPILE=0 builds a binary without this issue.

[essandess]

@deroulers, @vtjnash, @Keno, would you please chime in on the advisability of setting the build flag JULIA_PRECOMPILE=0 now that this issue is resolved?

[deroulers]

@essandess I would go for it (I mean, coming back to the previous state of the Portfile of Julia in MacPorts, without the flag). I had indeed experienced this issue while installing Julia with MacPorts. But then the Portfile needs to reference a commit in the GitHub repository, or one has to wait for the commit to make its way to a version.

[vtjnash]

It is generally ill advised to set any of the optional build options when making production builds of Julia, since the resulting binary will not be officially supported and may give users a bad experience
