=head1 HISTORY
|
|
|
|
In OpenSSL versions prior to 3.4, OpenSSL had a limitation regarding the
|
|
B<OPENSSLDIR>, B<MODULESDIR> and B<ENGINESDIR> build time macros. These macros
|
|
were defined at build time, and represented filesystem paths. This is common
|
|
practice on unix like systems, as there was an expectation that a given build
|
|
would be installed to a pre-determined location. On Windows however, there is
|
|
no such expectation, as libraries can be installed to arbitrary locations.
|
|
B<OSSL_WINCTX> was introduced as a new build time variable to define a set of
|
|
registry keys identified by the name openssl-<version>-<ctx>, in which the
|
|
<version> value is derived from the version string in the openssl source, and
|
|
the <ctx> extension is derived from the B<OSSL_WINCTX> variable. The values of
|
|
B<OPENSSLDIR>, B<ENGINESDIR> and B<MODULESDIR> can be set to various paths
|
|
underneath this key to break the requirement to predict the installation path at
|
|
build time.
|
|
|
|
=head1 NOTES
|
|
|
|
The output of C<openssl version -a> would typically be used when sending
|
|
in a bug report.
