Add warning to readme about dated libraries #4

Closed mabarnett0 closed 10 years ago

mabarnett0 commented 11 years ago

Gerbv versions from the Ubuntu repository contain a dated libgerbv with a bug that severely impacts gerber2graphtec's function. This issue is already resolved in the main source branch as of 2.3.0. If a pad's width or height falls below a certain amount relative to the total size of the board, the pad is no longer rendered in gerbv's pdf export.

Bug produced on Ubuntu 12.04 LTS, 3.2.0-40-generic-pae i686 with gerbv 2.5.0-1 using the following file (http://gist.github.com/mabarnett0/5523393). Apertures D13, D14, D20, D21, D24, and D25 are no longer rendered in the pdf output.

This issue can be mitigated by specifying a large "--window" argument but this may lead to further complications, suggest recommending Ubuntu and possibly Debian users compile from latest sources.

Hopefully this will keep others from wasting Kapton on bad cuts.

Thanks for reporting this---I've added a note to the README. Hopefully Ubuntu will update to the latest gerbv sometime soon.
