That implies OPENSSL_NO_ENGINE isn't defined while the engine header is missing, which isn't really a workable combination. Which version of OpenSSL is this?
I needed to install
Name : openssl-devel-engine Epoch : 1 Version : 3.2.2 Release : 5.fc41 Architecture : x86_64 Download size : 44.0 KiB Installed size : 52.8 KiB Source : openssl-3.2.2-5.fc41.src.rpm Repository : fedora Summary : Files for development of applications which will use OpenSSL and use deprecated ENGINE API. URL : http://www.openssl.org/ License : Apache-2.0 Description : OpenSSL is a toolkit for supporting cryptography. The openssl-devel-engine : package contains include files needed to develop applications which : use deprecated OpenSSL ENGINE functionality. Vendor : Fedora Project pavel@nemesis:~$ sudo dnf install openssl-devel-engine Updating and loading repositories: Repositories loaded. Package
Today I upgraded from FC40 to FC41, and only this library was installed to make the build.
The question is why the missing header was not detected by configure?
The description of this package says so the OpenSSL ENGINE is deprecated?
