This option is unavailable on 85non-Windows platforms. 86 87=back 88 89=head1 HISTORY 90 91In OpenSSL versions prior to 3.4, OpenSSL had a limitation regarding the 92B<OPENSSLDIR>, B<MODULESDIR> and B<ENGINESDIR> build time macros. These macros 93were defined at build time, and represented filesystem paths. This is common 94practice on unix like systems, as there was an expectation that a given build 95would be installed to a pre-determined location. On Windows however, there is 96no such expectation, as libraries can be installed to arbitrary locations. 97B<OSSL_WINCTX> was introduced as a new build time variable to define a set of 98registry keys identified by the name openssl-<version>-<ctx>, in which the 99<version> value is derived from the version string in the openssl source, and 100the <ctx> extension is derived from the B<OSSL_WINCTX> variable. The values of 101B<OPENSSLDIR>, B<ENGINESDIR> and B<MODULESDIR> can be set to various paths 102underneath this key to break the requirement to predict the installation path at 103build time. 104 105=head1 NOTES 106 107The output of C<openssl version -a> would typically be used when sending 108in a bug report. 109 110=head1 COPYRIGHT 111 112Copyright 2000-2024 The OpenSSL Project Authors.
