Re: [gforth] I2C framework

[Dennis Ruffer]

Another interesting unknown, on Fedora 22, I get:

address@hidden Forth]# gforth i2c.fs
sh: --silent: command not found

in file included from *OS command line*:-1
i2c.fs:23: libtool compile failed
>>>end-c-library<<<
Backtrace:
$B68C8B04 throw
$B68EA534 c(abort")

Here's a start, but this one gives:

address@hidden:~/Documents/Forth $ gforth i2c.fs

in file included from *OS command line*:-1
i2c.fs:26: Undefined word
    >>>O_RDWR<<< open throw
Backtrace:
$B68FBEDC throw
$B6908600 no.extensions
$B68FDE10 compiler-notfound1

But when I used r/w, I got:
address@hidden:~/Documents/Forth $ gforth i2c.fs Gforth 0.7.2, Copyright (C)

Gforth comes with ABSOLUTELY NO WARRANTY; for details type `license'

It's been a while since I've gotten this deep, so excuse my ignorance.

But help please. ;)
