My setup: Windows XP, R-2.6.0, Cygwin (not the Rtools version) When I tried to build a package, I was given this message: tar: c\:/X/Rpkgs/Drydown_1.41.tar: Cannot open: Input/Output error
Even manually typing the following caused the same error: tar chf 'c:/X/Rpkgs/Drydown_1.41.tar' Drydown I looked at the 2.5.1 and 2.6.0 build scripts. After restoring this section to the 2.6.0 build script: ## workaround for paths in Cygwin tar $filepath =~ s+^([A-Za-z]):+/cygdrive/\1+; } then $filepath evaluates to /cygdrive/c/X/Rpkgs/Drydown_1.41.tar and I was able to build packages again. (Posted in case someone else has the same problem and/or finds this useful.)
