[SOLVED] mozjs91 build fail on Slackware 15.0

lancsuk · 03-29-2022, 04:29 PM

Hiya guys,

I would like to build mozjs91 for Slackware 15.0, because mozjs78 is too old for Gnome 42.

I just customized the SlackBuild script and updated all Fedora patches.

Code:

warning: unnecessary `unsafe` block
    --> /tmp/firefox-91.7.0/third_party/rust/encoding_rs/src/mem.rs:1658:8
     |

Try with the configure option: --disable-warnings-as-errors

With the configure option --disable-warnings-as-errors I got error below.

Do you build it with this command?

Code:

SHELL=/bin/sh ./*.SlackBuild

The SHELL=/bin/sh is compulsory.

Yes

Which Rust compiler did you use? You might try the one in /extra and see if that helps. That's what I'm currently using for all Mozilla related code.

mozjs91 build failed with configure option --disable-optimize, with --enable-optimize the build works.

At the moment I am working on current ( Rust 1.59 ), but I will try the one in /extra as well.
