Marten,
I’m now trying to do the same in Windows but having problems.
I’m using vcpkg to build openssl and the only different in the configure line is the path to the installed vcpkgs
..\configure.bat -prefix C:\Qt\6.4.1\msvc2019_static -static -debug-and-release -nomake examples -nomake tests -nomake benchmarks -nomake manual-tests -nomake minimal-static-tests -openssl-linked -qtnamespace com_imaginando_qt_6_4_1 -- -DOPENSSL_ROOT_DIR="C:\vcpkg\installed\x64-windows-static\" -DOPENSSL_USE_STATIC_LIBS=TRUE
Inside C:\vcpkg\installed\x64-windows-static\include there is the openssl folder
And inside the C:\vcpkg\installed\x64-windows-static\lib there is:
libcrypto.lib
libeay32.lib
libssl.lib
However, the result is:
CMake Error at qtbase/cmake/QtBuildInformation.cmake:490 (message):
Feature "openssl": Forcing to "ON" breaks its condition: QT_FEATURE_openssl_runtime OR QT_FEATURE_openssl_linked Condition values dump: QT_FEATURE_openssl_runtime = "OFF"
QT_FEATURE_openssl_linked = "OFF"Call Stack (most recent call first):
qtbase/cmake/QtFeature.cmake:281 (qt_configure_add_report_error)
qtbase/cmake/QtFeature.cmake:403 (qt_feature_check_and_save_internal_value)
qtbase/cmake/QtFeature.cmake:155 (qt_evaluate_feature)
qtbase/cmake/QtFeature.cmake:349 (qt_evaluate_config_expression)
qtbase/cmake/QtFeature.cmake:606 (qt_evaluate_feature)
qtbase/cmake/QtFeature.cmake:575 (qt_feature_module_end)
qtbase/src/CMakeLists.txt:9 (qt_feature_evaluate_features)
Trying to build without this, worked perfectly.
What am I missing here?
Thanks!
Nuno
