Failed to install ruby 3.1.0 on M1

[ihomway]

Tried to install ruby 3.1.0 via rbenv, but it returns failed.

It said ld: library not found for -lcapstone, but I can find the capstone library, which was installed via Homebrew.

Output

$ rbenv install 3.1.0

I have solved this issue by export capstone library (I'm using Fish shell).

$ set -gx LDFLAGS "-L/opt/homebrew/opt/capstone/lib"
$ set -gx CPPFLAGS "-I/opt/homebrew/opt/capstone/include"

[sungpeo]

Thanks. I use below environment variables. (I'm using Zsh)

export LDFLAGS="-L/opt/homebrew/opt/capstone/lib"
export CPPFLAGS="-I/opt/homebrew/opt/capstone/include"

[maximecb]

Normally capstone is optional. We use it in YJIT but only when cppflags="-DRUBY_DEBUG" is specified. Are you building in debug mode?

I have the same problem as @ihomway, and I'm not passing any special flags to rbenv install or in my environment. If you're curious, I've attached a build log file. Here's the configuration summary from the log file:

I was able to work around the problem by uninstalling capstone on my system:

❯ brew uninstall capstone
Error: Refusing to uninstall /home/linuxbrew/.linuxbrew/Cellar/capstone/4.0.2
because it is required by bloaty, which is currently installed.
You can override this and force removal with:
  brew uninstall --ignore-dependencies capstone

❯ brew uninstall bloaty
Uninstalling /home/linuxbrew/.linuxbrew/Cellar/bloaty/1.1_6... (8 files, 752.8KB)

❯ brew uninstall capstone
Uninstalling /home/linuxbrew/.linuxbrew/Cellar/capstone/4.0.2... (25 files, 19.1MB)

When I did that, it looks like the ./configure script failed to detect capstone installed on my system, and decided to not compile it. The configuration summary for me changed to this:

I don't know why the configure script was able to find capstone on my system, but gcc was not able to find it when building Ruby file-by-file.

In any case, uninstalling capstone (by also uninstalling bloaty) and then building Ruby allowed me to build Ruby 3.1.0, and I was able to reinstall bloaty afterwards.

Here is the build log from the successful build:
ruby-build.20220324141410.312020.log

[maximecb]

Just to update everybody, we're in the process of porting YJIT to Rust and hoping to upstream that next month. This should fix the capstone issue as the library will only be used when building in dev mode.

[patlux]

I had to remove my ~/.gem folder to make LDFLAGS="-L/opt/homebrew/opt/capstone/lib" CPPFLAGS="-I/opt/homebrew/opt/capstone/include" rtx install to work.

Otherwise I still got:
