🐛 Failed to compile on arch caused by onig_sys error

Run commandyay -S git-delta, compilation process failed:

Same error occurs when running makepkg on latest commit 3423f36f144f29fbed68f1679b from master.

Installing git-delta-bin works well

[Kr1ss-XD]

The git-delta package builds fine in a clean (Arch) chroot, which points to some kind of non-default setup on your end.
Just a guess, but could you please check if $LLVM_CONFIG_PATH is set in you build environment ?
If that's the case, please try to build with

LLVM_CONFIG_PATH= makepkg -csr

in a clean build folder.

Thx

Hi @Kr1ss-XD,

I checked in my terminal and I don't have any environment set as LLVM_CONFIG_PATH.

LLVM_CONFIG_PATH= makepkg -csr runs in a clean build folder, unfortunately, the same error occurs.

[Kr1ss-XD]

Well thx for checking nevertheless; I'm out of ideas then unfortunately. Hope you are okay with using the -bin package.

[KevCui]

@Kr1ss-XD No worry, all good, binary works well :) thx

Also can't build onig_sys:

Same without this env variable:

I think you're suffering from this: rust-onig/rust-onig#109. I see that it has affected several projects, but I'm afraid I don't have any technical insight into it.

I'm also sorry to say that I investigated downgrading onig_sys and found I was unable to due to the dependency graph (syntect requires the recent onig_sys, and delta requires a recent syntect).

So that's information but I'm not sure it helped!

[dandavison]

Is this still a problem? There has not been a new release of delta since 0.1.1 but for people who were having this problem when building from source I'd be interested to know if it is fixed in master.

[Yanpas]

I've built delta, guess may be closed

[MarcoIeni]

Today I installed this project on arch with yay -S git-delta. It worked fine :)

[dandavison]

OK, thanks everyone. I'll close for now.
