SBCL supports multi-threading on OS X and linux, but unfortunately it doesn’t enable by default on mac. I had a hard time to identify this after I changed to linux to play with hunchentoot. To solve this, I need to enable threads when compile it from the source.
1. Download and unarchive the source.
2. In the root of directory of the source, create a file named
customize-target-features.lisp with content
(lambda (features) (flet ((enable (x) (pushnew x features)) (disable (x) (setf features (remove x features)))) ;; Threading support, available only on x86/x86-64 Linux, x86Solaris ;; and x86 Mac OS X (experimental). (enable :sb-thread)))
3. Then, compile and install SBCL from its source.
sh make.sh && sudo sh install.sh
- Donwload and unarchive the source. Then, compile and install with option
sh make.sh --with-sb-thread && sudo sh install.sh
