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

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

2671 perform build related tasks. The databanks are:
2673 %config Configured things.
2674 %target The OpenSSL config target with all inheritances
2676 %disabled The features that are disabled.
2677 @disablables The list of features that can be disabled.
2678 %withargs All data given through --with-THING options.
2679 %unified_info All information that was computed from the build.info
2688 Print a brief help message and exit.

2719 Print the main make variables generated in the current configuration
2721 =item B<--build-parameters> | B<-b>
