Of itself, this is not an explanation for a missing cyglz4-1.dll, as it is contained in both versions of the package (even if the package version has changed, the soversion doesn't change) (compare the package contents seen at [1]) [1] https://cygwin.com/packages/x86_64/liblz4_1/ setup thinks liblz4_1 is already installed, so doesn't install it again. >> 2017/12/02 14:06:47 Adding required dependency liblz4_1: Selecting already-installed version . This is weird, since it seems to indicate that PrereqChecker::isMet() noted it as needing to be installed, but that PrereqChecker::selectMissing() thinks it is already installed. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
