81 # libcrypto.a) is to eliminate dependency on specific run-time,

83 # to achieve just that. Unfortunately on Linux it's impossible
84 # to eliminate the dependency completely for openssl executable
85 # because of getaddrinfo and gethostbyname calls, which can
86 # invoke dynamically loadable library facility anyway to meet
87 # the lookup requests. For this reason on Linux statically
88 # linked openssl executable has rather debugging value than

2752 %target The OpenSSL config target with all inheritances
2754 %disabled The features that are disabled.
2755 @disablables The list of features that can be disabled.
2756 %withargs All data given through --with-THING options.
2757 %unified_info All information that was computed from the build.info
2766 Print a brief help message and exit.
2770 Print the manual page and exit.
