build beta on OpenBSD 7.4 seems to be broken ATM #24

Closed dhuseby closed 1 month ago

I got the following error message while trying to build beta and haven't had the time to debug it yet:

It looks like that solution is to just add the file_set_times feature to the opener dependency to make this error go away.

it isn't the better moment to build beta currently. it requires a 1.77.0 (stable) compiler which was commited in openbsd ports tree only few hours ago.

could you ensure that you are using (and building) the expected versions ?

at the beginning of the build, you should have something like:

Fri Mar 22 11:38:27 CET 2024: info: building: 1.78.0-beta.1 (efd9d2df1 2024-03-18)
Fri Mar 22 11:38:27 CET 2024: info: required stage0:
  "compiler": {
    "date": "2024-02-04",
    "version": "beta"
  },
Fri Mar 22 11:38:27 CET 2024: info: rustc -vV
        rustc 1.77.0 (aedd173a2 2024-03-17) (built from a source tarball)

You mean OpenBSD 7.4?

Oops. Yes. Fixed.

I just checked out the current ports and sources and I'm building the 1.77 rust right now.

dhuseby commented 5 months ago

I just did a fresh install of 7.4 i386, used cvs to pull down the current ports, src, and xeoncara trees. Tried building 1.77 but it fails. This is on an old 32-bit laptop from 2008 so I'm not sure if it is because of the i386/32-bit build is broken or if I didn't something wrong setting up my test box. Do I need to build and run the current kernel/sys/ports for this to work?

semarie commented 5 months ago

using -current ports tree on 7.4 system isn't a supported configuration. for example, for building lang/rust, it is using binary bootstrap build for -current, and the binaries isn't necessary compatible with 7.4.

it is preferable to install a -current system (mostly 7.5 currently) using snapshots.

@dhuseby If I remember, rustc can't compile itself on 32-bits platforms.

I've build 1.73, 1.74, 1.75, 1.76 & 1.77 on OpenBSD 7.4 x86_64 during the weekend. 1.77 can be downloaded there for those who don't want to build it manually, and its SHA256 hash is 66c4952e1e5ed91f0cb5e0714b4e379c61d3583f88968eeda32838df9d17a58b

It works well. I am building all bootstraps natively, and it is also how OpenBSD is producing the package on i386.

My bad, it was an old problem which has been fixed.

semarie commented 1 month ago

closing. building is expected to be done on OpenBSD -current version.
