Thank you so much.
After Installing OpenSSL development package, should I install Qt again?

You should do a clean Qt rebuild without old build artefacts.

@jsulm
Thank you. It works.

@chris_rookie

Can you help me on how you have installed the OpenSSL development package?

I already have installed in my desktop still i am getting error :

/home/huayu/qt-everywhere-opensource-src-5.9.2/qtbase/config.tests/openssl/openssl.cpp:40:30: fatal error: openssl/opensslv.h: No such file or directory
compilation terminated.

Thank you,

@Jignesh-Patel hi,

Which version of OpenSSL did you install ?
Did you install the development package ?

[Jignesh Patel]

@SGaist ,

Thank you for reply,

I have installed openssl "OpenSSL 1.1.0f 25 May 2017" on ubuntu 16.04 LTS and also libssl-dev revision is 1.0.2g-1ubuntu4.20.
I am trying to cross compile qt 5.7.1 using following configuration:
"./configure -v -opensource -confirm-license -no-pch -no-xcb -no-opengl -openssl -make libs -device imx6 -compile-examples -device-option CROSS_COMPILE=/home/jignesh/var_mx6ul_dart_debian_stretch93/toolchain/gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf- -sysroot <rootfs> -no-gcc-sysroot -prefix <installdir>"

Best Regards,
Jignesh Patel

Then that's the issue, the Qt version you want to use is too old to support OpenSSL 1.1. Either update it or install OpenSSL 1.0. There was a huge incompatible jump between the 1.0 and 1.1 versions.

OpenSSL 1.0
Thank you for your support.

I have installed OpenSSL version "OpenSSL 1.0.2g 1 Mar 2016" but getting same error.
I have some questions about this:

1. As I am cross-compiling qt in my ubuntu-desktop, does it need to cross-compile openssl before cross compiling qt.
2. Does it required to add the path of OpenSSL in the ./config command line argument?

Best Regards,
Jignesh Patel

[SGaist]

You need all dependencies of the right architecture when cross-compiling.

Depending on the distribution you use on your target, you can install the required development packages and sync them back to your main machine as sysroot to use when cross-compiling.

[Jignesh Patel]

@SGaist
Thank you for your reply.

Successfully cross-compiled source of 5.7.1:
the issue has been resolved by adding the following:
After downloading the source and compiling OpenSSL 1.0.2 stable.

./config --prefix=/opt/openssl_build_stable -shared
make
make test
sudo make install

Link open ssl in qt config:

-openssl -I /opt/openssl_build_stable/include -L /opt/openssl_build_stable/lib
