Hi guys,
Alex want me to share my experience with pil21 on macOS to this list, and he
says this is the first version of pil21 in the Apple world. Though I didn’t do
much, I’ll just describe what I did:
On my MacBook Pro (Retina, 15-inch, Mid 2014) running macOS Catalina (Version
10.15.3) with up-to-date homebrew,
(1) Simply grabbed his archive and untarred it somewhere:
$ wget https://software-lab.de/pil21.tgz
(2) Installed clang, llvm, pkg-config
$ brew install clang llvm pkg-config
(3) Installed libffi from its source code, because my brew doesn’t seem to know
about it:
$ git clone https://github.com/libffi/libffi.git
$ cd libffi
$ ./autogen.sh
$ ./configure
$ make
$ sudo make install
Note: I tried,
$ brew install libffi
later again, and it seems to work. I don’t know why...
(4) Follwing his advice, I modified pil21/src/Makefile to avoid build error on
exp.so:
all: $(BIN)/picolisp # $(LIB)/ext.so
According to Alex, this shared library is used only when called from
applications.
(5) Then just built pil21:
$ cd pil21/src
$ make
(6) Tested bin/picolisp:
$ ../bin/picolisp
: (+ 1 2 3)
-> 6
: (de fib (n) (if (>= n 2) (+ (fib (- n 1)) (fib (- n 2))) 1))
-> fib
: (fib 22)
-> 28657
FYI, I tried two different clangs and both seem to produce working picolisp:
(1) clang installed by homebrew (brew install clang)
clang version 9.0.1
Target: x86_64-apple-darwin19.3.0
Thread model: posix
InstalledDir: /usr/local/opt/llvm/bin
(2) clang bundled with Xcode Version 11.3.1 (11C504)
Apple clang version 11.0.0 (clang-1100.0.33.17)
Target: x86_64-apple-darwin19.3.0
Thread model: posix
InstalledDir:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
That’s almost all I did.
I might try pil21 on iOS, though it’s a whole different story.
Cheers,
__Mak
