@jsulm
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.

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,

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:

As I am cross-compiling qt in my ubuntu-desktop, does it need to cross-compile openssl before cross compiling qt.
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
