[Interest] Qt6 - Fails to compile when openssl-linked enabled

[Mårten Nordheim]

Ah, I don’t think OPENSSL_LIBS is in use anymore!
I think it was still left printed at the end of configure, I’m not sure the change removing it was merged into 6.4.
Please use the FindOpenSSL cmake find-module variables: https://cmake.org/cmake/help/latest/module/FindOpenSSL.html
In your case, passing -DOPENSSL_ROOT_DIR="/Users/nsantos/Qt-Utils/openssl"
at the end of your configure line, something like this:

./configure -prefix …. -openssl-linked -- -DOPENSSL_ROOT_DIR="…"

Marten,

Thank you for your reply.

Yes the patch required? My configure line was:

./configure -prefix /Users/nsantos/Qt/6.4.2/macos -static -debug-and-release -nomake examples -nomake tests -nomake benchmarks -nomake manual-tests -nomake minimal-static-tests -openssl-linked -I/Users/nsantos/Qt-Utils/openssl/include OPENSSL_LIBS="/Users/nsantos/Qt-Utils/openssl/lib/libssl.a /Users/nsantos/Qt-Utils/openssl/lib/libcrypto.a”

Best,

Nuno

Marten,

Thanks for your reply.

I’m on branch 6.4.2 and before any configure I always call:

git submodule foreach --recursive "git clean -dfx" && git clean -dfx

Should I try with another branch?

No, it shouldn't be needed. I just configured 6.4 branch locally and it
works fine. With only
https://codereview.qt-project.org/c/qt/qtbase/+/446542
as the extra patch.
I think this might indicate that the openssl compile test fails, which
could disable the feature. But just to make sure; do you call configure
like `../qt5/configure ... -openssl-linked` ?



Regards,

Nuno

Hey,

If this is a clean build I need to know which branch you are building.
If not then you could try deleting CMakeCache.txt and reconfiguring,
there were some changes around configuration of openssl recently
which may be conflicting with values in the cache.

Hi,

I’m trying to compile Qt 6 with openssl-linked but I’m having this error and
I’m not being able to interpret it.

What is failing? Can you please help me here?

Thanks in advance!

Regards,

Nuno
