Error building SpiderMonkey: llvm-objdump

[Seleucids]

I'm trying to compile A28 on Ubuntu 24.04 and I encounter this error while building the libraries.

 0:04.37 DEBUG: llvm_objdump: Looking for llvm-objdump
 0:04.37 ERROR: Cannot find llvm-objdump

I searched through apt but couldn't find such a package. The same error occurs on Debian 12

My command was 

./build-source-libs.sh -j28

 

On a separate note, the wiki on BuildInstructions should include curl, git-lfs and wget to the list of dependencies

This error does not occur on other Linux distributions. Only Debian based.

Do you have llvm installed ?

llvm

System says so when I do apt list --installed, but the build doesn't see it. 

(I'm nub at Debian based distros)

@Seleucids, "llvm" is a binary package in Debian.

What you need to check for is
llvm-dev

https://packages.debian.org/search?keywords=llvm-dev

"-dev" packages are for building stuff from source.

I installed this package and replaced llvm and it worked! Thank you so much!

 

For later people who encounter similar problems: install llvm-dev and remove the other llvm packages.

The list of build dependencies should include git-lfs curl llvm-dev
