87 # -static while -static is also a pass-through compiler option (and

91 # argued that the only reason to produce statically linked
92 # binaries (and in context it means executables linked with
93 # -static flag, and not just executables linked with static
94 # libcrypto.a) is to eliminate dependency on specific run-time,
95 # a.k.a. libc version. The mentioned config options are meant
96 # to achieve just that. Unfortunately on Linux it's impossible
97 # to eliminate the dependency completely for openssl executable
98 # because of getaddrinfo and gethostbyname calls, which can
99 # invoke dynamically loadable library facility anyway to meet
100 # the lookup requests. For this reason on Linux statically
101 # linked openssl executable has rather debugging value than
102 # production quality.
