Qt 5.9.7 compilation with support for OpenSSL3.x

Vibhu

Hi all,

As we know Qt5.9.7 is not defaultly compatible with OpenSSL3.x, but for our requirements we are trying to version up from OpenSSL1.x to OpenSSL3.x. Is there any Qt patch available which we can incorporate into our Qt source to make support for OpenSSL3.x feasible?

@Vibhu You can search for the commits which introduced OpenSSL3 support in Qt.
It will be probably easier to upgrade Qt version than patching and building old Qt version.

Vibhu

We cannot upgrade Qt version to higher than 5.9.7 since we are limited to use GCC 4.9.2, all higher version of Qt will require GCC5 and up.

@Vibhu Then you will have to back port the OpenSSL3 patches to Qt 5.9.7 if you really need that OpenSSL version.

Vibhu

Could you guide me to the link of the patch which supported OpenSSL3 in Qt?

Hi,

This bug report to a gist that explains what to do.

Note that this is for 5.15 further ajustements might be needed since your are on 5.9.
