qt4-mac fails to build with libressl 2.3.3

[bK4gYuRo]

After upgrading libressl to 2.3.3 I cannot build qt4-mac 4.8.7 on Yosemite 10.10.5

These are the errors in the log:

I wonder if patch similar to ​https://issues.asterisk.org/jira/browse/ASTERISK-24799 can be used?

[bK4gYuRo]

or maybe this approach ​https://wiki.freebsd.org/LibreSSL/PatchingPorts

Resolution

Sometimes you will find an example for OPENSSL_NO_SSL2 in the code, do something similar for SSLv3. This tends to use #ifdef guards around the SSLv2 or SSLv3 code.

Example SSLv3_server_method code

ctx = SSL_CTX_new (server ? SSLv3_server_method() : SSLv3_client_method ());
Becomes

#ifndef OPENSSL_NO_SSL3
ctx = SSL_CTX_new (server ? SSLv3_server_method() : SSLv3_client_method ());
#else
ctx = SSL_CTX_new (server ? SSLv23_server_method() : SSLv23_client_method ());
SSL_CTX_set_options(ctx, SSL_OP_NO_TLSv1|SSL_OP_NO_SSLv2);
#endif
This retains compatibility with !OpenSSL 0.9.8, 1.0.0 and 1.0.1

You can use SSLv23 methods, these have been retained in LibreSSL but negotiate TLSv1, TLSv1.1 or TLSv1.2. What it will negotiate is controlled using the SSL_CTX_set_options. You will actually improve ports that you modify!

patch allowing qt4-mac to build against libressl by wrapping SSLv3_* function calls in macro checks using '#ifndef OPENSSL_NO_SSLV3'

I ran into this issue as well and have attached the patch I put together along with the Portfile I used to apply the patch.

See these two attachments:

Looks like this issue was fixed in ​https://github.com/macports/macports-ports/commit/e60744bf4b2421b8065e51631bab67f852a01e47 as patch (a). Closing
