how to run recent gambit with R7RS?
Here's a hello world: https://github.com/gambit/hello
It can be run with:
gsi -:r7rs github.com/gambit/hello
That command will download the module into ~/.gambit_userlib/ (if it isn't there already) and then run it.
There's also a graphical demo that relies on Xlib and pkg-config:
gsi -:r7rs github.com/gambit/xlib/demo
The -:r7rs flag puts Gambit in R7RS mode (instead of the native Gambit mode). It's not required for the above examples; the native mode works too. Try `gsi -:help` (and separately, `gsi -help` and `gsc -help`) for more about the available options.
