[Slackbuilds-users] Missing "lld" on x86 Slackware-15.0

[Shahab Vahedi]

I need to pick your brain on something. There is this program
called Bear that recently moved their code base from C++ to Rust.
When building it, I noticed that the build fails on i586 version
of Slackware-15.0 [1], but is fine on x86_64 variant.

I have narrowed down the problem to missing "lld" binary on x86
Slackware (llvm-13) [2]. Indeed, Slackware64-15.0's llvm package
(llvm-13 again) provides the "lld" linker.

At first I thought maybe I could get away with having a link
from "lld" to "ld", but that was not a success [3]. The linking
phase really needs the "lld" tool.

I finally managed to have "lld" on x86 Slackware-15.0 by installing
llvm-22.1 package from the "extra" repository. That package does
provide the "lld" binary. Moreover, I was not in the mood for
compiling "llvm-opt", so I did not try that, but I'm going to
_assume_ that it also provides the "lld" tool.

After having "lld" on the system, the build went just fine.

To summarise the situation:

1. Bear builds fine on Slackware64-15.0 because there is lld
2. Bear faild to build on Slackware-15.0 since there's no lld
3. The linking process does really need lld (cannot be bypassed)

Now, what should I do with this?

- Shall I add "llvm-opt", to the "REQUIRES" field and explain
in the README that is only needed for x86 variants? Please keep
in mind that I actually haven't tried "llvm-opt" but the pre-built
package of llvm-22.1 from the "extra" repository.

- Should I create two separate packages (Bear vs Bear32)?
I'm not in favour of this option.

- Or maybe something else?

the problem manifests itself during the linking phase as
note: collect2: fatal error: cannot find 'ld'
          compilation terminated.
what actually is not found is "lld" and not "ld".

[3]
If "ld" is used instead of "lld", the "ld" will return an error
  /usr/bin/ld: anonymous version tag cannot be combined with other version tags
               collect2: error: ld returned 1 exit status
