85 # -static while -static is also a pass-through compiler option (and
86 # as such is limited to environments where it's actually
87 # meaningful), it triggers a number configuration options,

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