  114. # argued that the only reason to produce statically linked
  115. # binaries (and in context it means executables linked with
  116. # -static flag, and not just executables linked with static
  117. # libcrypto.a) is to eliminate dependency on specific run-time,
  118. # a.k.a. libc version. The mentioned config options are meant
  119. # to achieve just that. Unfortunately on Linux it's impossible
  120. # to eliminate the dependency completely for openssl executable
  121. # because of getaddrinfo and gethostbyname calls, which can
  122. # invoke dynamically loadable library facility anyway to meet
  123. # the lookup requests. For this reason on Linux statically
  124. # linked openssl executable has rather debugging value than
  125. # production quality.
