Subject: [PATCH] Fix building against LibreSSL
|
|
|
|
LibreSSL declares OPENSSL_VERSION_NUMBER == 2.0 but does not include most
|
|
changes from OpenSSL >= 1.1.
|
|
|
|
To work around this:
|
|
|
|
- Check to see if LIBRESSL_VERSION_NUMBER is defined.
|
|
- If so, define MODSSL_USE_OPENSSL_PRE_1_1_API.
|
|
- Change all checks for OPENSSL_VERSION_NUMBER < 0x10100000L to
|
|
'#if MODSSL_USE_OPENSSL_PRE_1_1_API'
|
|
|
|
