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

047d97af AP |
111 | # argued that the only reason to produce statically linked |
112 | # binaries (and in context it means executables linked with | |
113 | # -static flag, and not just executables linked with static | |
114 | # libcrypto.a) is to eliminate dependency on specific run-time, | |
115 | # a.k.a. libc version. The mentioned config options are meant | |
116 | # to achieve just that. Unfortunately on Linux it's impossible | |
117 | # to eliminate the dependency completely for openssl executable | |
118 | # because of getaddrinfo and gethostbyname calls, which can | |
119 | # invoke dynamically loadable library facility anyway to meet | |
120 | # the lookup requests. For this reason on Linux statically | |
121 | # linked openssl executable has rather debugging value than | |
122 | # production quality. | |
