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