Package: libserialport-ruby1.8 Version: 0.7.0-1 Severity: normal Tags: upstream patch
Hi,
Reading the CTS and setting the DTR line state is broken:
$ irb1.8
irb(main):001:0> require 'serialport'
=> true
irb(main):002:0> s = SerialPort.new('/dev/ttyUSB0', 19200)
=> #<SerialPort:0xb74eaf7c>
irb(main):003:0> s.dtr = 0
irb: symbol lookup error: /usr/lib/ruby/1.8/i486-linux/serialport.so:
undefined symbol: set_signal
zsh: exit 127
$ irb1.8
irb(main):001:0> require 'serialport'
=> true
irb(main):002:0> s = SerialPort.new('/dev/ttyUSB0', 19200)
=> #<SerialPort:0xb74c8a30>
irb(main):003:0> s.cts
irb: symbol lookup error: /usr/lib/ruby/1.8/i486-linux/serialport.so:
undefined symbol: get_line_signals_helper
zsh: exit 127
The attached patch fixes this problem. The version is very old, there is a
new upstream version (0.7.2) available:
http://github.com/toholio/ruby-serialport
And even a forked version 1.0.1 (since the original hasn't been modified since
2008) at http://github.com/toholio/ruby-serialport
If you need help, just contact me. If you aren't interested in maintaining
this package any more, I would gladly take it over.
Cheers,
- Alexander
