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. | |
