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

2536 %target The OpenSSL config target with all inheritances
2538 %disabled The features that are disabled.
2539 @disablables The list of features that can be disabled.
2540 %withargs All data given through --with-THING options.
