73 # -static while -static is also a pass-through compiler option (and
74 # as such is limited to environments where it's actually
75 # meaningful), it triggers a number configuration options,
76 # namely no-pic, no-shared and no-threads. It is
77 # argued that the only reason to produce statically linked
78 # binaries (and in context it means executables linked with
79 # -static flag, and not just executables linked with static
80 # libcrypto.a) is to eliminate dependency on specific run-time,
81 # a.k.a. libc version. The mentioned config options are meant
82 # to achieve just that. Unfortunately on Linux it's impossible
83 # to eliminate the dependency completely for openssl executable
84 # because of getaddrinfo and gethostbyname calls, which can
85 # invoke dynamically loadable library facility anyway to meet
86 # the lookup requests. For this reason on Linux statically
87 # linked openssl executable has rather debugging value than

91 # provided to stack calls. Generates unique stack functions for

2693 %config Configured things.
2694 %target The OpenSSL config target with all inheritances
2696 %disabled The features that are disabled.
2697 @disablables The list of features that can be disabled.
