Package: ghostscript
Version: 8.71~dfsg-2
Severity: normal
When building freefem++ I encoutered the following problem
epstopdf figures/mesh_sample.eps --outfile=cpfigs/mesh_sample.pdf
GPL Ghostscript 8.71: ./psi/iscan.c(333): Can't refill scanner input buffer!GPL
Ghostscript 8.71: Unrecoverable error, exit code 255
After some googling I found that this problem has been reported in Ubuntu
with a patch by Till Kamppeter. See
http://www.mail-archive.com/[email protected]/msg06544.html
I had to slightly modify the patch to solve the problem.
Proposed patch is attached
