openSSL in QT

[saeid0034]

@SGaist yes by adding dll in exe folder im able to post data
but there is anyway to include openssl static?

Not without building Qt by yourself as normal Qt builds load OpenSSL libs at runtime.

@jsulm can anyone tell me i need to pass what in ./configure to build qt with openssl statically
i use this for build qt static for now

configure -opensource -confirm-license -static -platform win32-g++ -optimize-size -opengl desktop -prefix "C:\Qt\static" -skip webengine -nomake tests -nomake examples -qt-zlib -qt-libjpeg -qt-libpng -qt-freetype -qt-pcre -qt-harfbuzz -qt-tiff

i need to add what to build qt static + openssl?

edit: i see this page in wiki
based of this page i need to build qt like this

OPENSSL_LIBS='-L/d/build/ssl/lib -lssl -lcrypto' && configure -opensource -confirm-license -static -platform win32-g++ -openssl-linked -optimize-size -opengl desktop -prefix "C:\Qt\static" -skip webengine -nomake tests -nomake examples -qt-zlib -qt-libjpeg -qt-libpng -qt-freetype -qt-pcre -qt-harfbuzz -qt-tiff

in this configure OPENSSL_LIBS is Location of openssl-1.1.1g i compiled before (with mingw)

its all ok?

OPENSSL_LIBS='-L/d/build/ssl/lib -lssl -lcrypto

This looks like linking against shared OpenSSL libs.

@jsulm you say i do not need to set OPENSSL_LIBS?
and by the way i think this 2 lib use for shared version libssl.dll.a & libcrypto.dll.a

and also i use mingw to build openssl and Qt

You don't need to rebuild Qt. Just select OpenSSL in the installer, and do what is suggested here:

@Markus43 thanks for reply, but i need openssl for static build

Then the question is: Does OpenSSL need to be static, too?

If you can live with using OpenSSL dlls while using static Qt, you can just add the following to your configure line (also with OpenSSL from the installer) and you're done.
e.g. for x86 builds:

-openssl -I C:\Qt\Tools\OpenSSL\Win_x86\include -L C:\Qt\Tools\OpenSSL\Win_x86\lib

for using openssl static too i need to build Qt static with openssl again?

Yes. Think about it: when linking against dlls, the linker only links the OpenSSL function calls in a way that they call the dll. When linking against static OpenSSL, the linker copies the called functions' code into the executable being built.

Anyhow, I never did a static build of OpenSSL, so I'm not sure if the line above works for static builds, too.
