how to compile qt static with open ssl

SGaist

Hi,

The config log is not readable.

In any case, you should check the test logs to see why the OpenSSL related tests failed.

SherifOmran

I am running win7 and I noticed the following :
giving this command runs

configure.bat -release -opensource -confirm-license -opengl dynamic -platform win32-msvc2015 -openssl -I C:\OpenSSL\include -L c:\OpenSSL\lib -nomake examples -nomake tests -no-direct2d -skip qt3d -skip qtactiveqt -skip qtandroidextras -skip qtcanvas3d -skip qtconnectivity -skip qtdoc -skip qtgamepad -skip qtgraphicaleffects -skip qtlocation -skip qtmacextras -skip qtmultimedia -skip qtquickcontrols -skip qtquickcontrols2 -skip qtscript -skip qtscxml -skip qtsensors -skip qtserialbus -skip qtserialport -skip qtspeech -skip qtsvg -skip qtvirtualkeyboard -skip qtwayland -skip qtwebchannel -skip qtwebengine -skip qtwebview -skip qtwinextras -skip qtx11extras -skip qtxmlpatterns -static -static-runtime  -openssl-linked

but when i add the following , i get the error message above

OPENSSL_LIBS="-LC:\OpenSSL\lib -lssl -lcrypto"

what is this? some threads state we should use this OPENSSL_LIBS="-llibeay32 -lssleay32" but i am lost and i get the same error with both.

SherifOmran

I pasted the config log file here
https://pastebin.com/mNPmbGAz

when i tried to compile an empty file, i get this
mingw32-make[1]: *** No rule to make target 'C:/Qt/Qt-5.12.4/lib/libQt5Widgets.a', needed by 'release/ssl.exe'. Stop

knowing that open ssl was compiled using vs 2017 nmake. I had to compile it as lib and then as static. the parameter i gave in -i and -l was the path to the static library.
should i start from the beginning?

SGaist

What version of OpenSSL are you trying to use ?

SherifOmran

1.1.1 and current master

SherifOmran

i started over again and downloaded qt 5.13.0.
I can compile it with

..\configure.bat -static -platform win32-g++ -release -prefix "c:\Qt\qt5.13.0_static" -opengl desktop -plugin-sql-sqlite -sql-sqlite -strip

but i want to add openssl support. how should i do it? QT 5.13.0 online installer had a check box to download openssl and it downloaded a library in C:\QT\qt5.13.0\Tools\OpenSSL\Win_x86\lib
should i use this library?
what should i add to the command line?

what is the equivalent to these libraries in windows
SET OPENSSL_LIBS="/usr/${_arch}/lib/libssl.a /usr/${_arch}/lib/libcrypto.a -lws2_32 -lgdi32 -lcrypt32 -ldnsapi -liphlpapi"

hi
https://stackoverflow.com/questions/20843180/is-there-any-way-to-building-static-qt-with-static-openssl

i think you also need
-openssl-linked

SherifOmran

i tried the following

..\configure.bat -static -platform win32-g++ -release -prefix "c:\Qt\qt5.13.0_static" -opengl desktop -plugin-sql-sqlite -sql-sqlite -strip  -openssl-linked -I "C:\QT\qt5.13.0\Tools\OpenSSL\src\include" -L "C:\QT\qt5.13.0\Tools\OpenSSL\Win_x86\lib" OPENSSL_LIBS="-libcrypto -libssl"

and

..\configure.bat -static -platform win32-g++ -release -prefix "c:\Qt\qt5.13.0_static" -opengl desktop -plugin-sql-sqlite -sql-sqlite -strip  -openssl-linked -I "C:\QT\qt5.13.0\Tools\OpenSSL\src\include" OPENSSL_LIBS="C:\QT\qt5.13.0\Tools\OpenSSL\Win_x86\lib\libcrypto C:\QT\qt5.13.0\Tools\OpenSSL\Win_x86\lib\libssl"

but they both fail
The sql library included here is the one downloaded from the qt online installer 1.1.1 b

I also tried with static libraries produced from compiling ssl as dll for release and then with no-shared (static) but also failed at config

SGaist

One thing I'm not sure but don't you have an option to tell which version of OpenSSL you are using ?

SherifOmran

i don't have this option. The packaged version of openssl from QT Installer is 1.1.1b and gets installed under Qt\tools path. The version i was trying to install is 1.1.1c and the master branch after being compiled.

The build works without openssl linked and without the I and I parameters and OPENSSL_LIBS parameter.
I am getting puzzled. The simple question is what is -I and -L parameters and were is Qt expecting to find the header files and which libraries should i link against?

SGaist

Are you trying to build a 32 or 64 bit version of Qt ? If the later, you are using the wrong architecture for OpenSSL.

SherifOmran

ooops, this could be. how can i tell make to compile the 32 bit version of qt?
i used this -platform win32-g++
how can we make sure that openssl is 32 bits and not 64?

SherifOmran

i compiled openssl as follows

perl configure VC-WIN64A --release --prefix=T:\openssl\dll\x64\release -openssldir=T:\openssl\ssl
nmake
nmake test
nmake install_sw //this will copy to the dll folder and to program files/openssl/include / headers
nmake clean


perl configure VC-WIN64A --debug --prefix=T:\openssl\dll\x64\debug -openssldir=T:\openssl\ssl
nmake
nmake install_sw
nmake clean

//release static
perl configure VC-WIN64A no-shared --release --prefix=T:\openssl\lib\x64\release -openssldir=T:\openssl\ssl
nmake
nmake install_sw
nmake clean


perl configure VC-WIN64A no-shared --debug --prefix=T:\openssl\lib\x64\debug -openssldir=T:\openssl\ssl
nmake
nmake install_sw
nmake clean

and compile Qt with nmake using visual studio 2019

SGaist

How are you compiling Qt ?
What setup do you do in the terminal you use for the build ?

SherifOmran

I downloaded Openssl 32 from the following link
and compiled qt with the following configure

set OPENSSL_HOME=C:\OpenSSL-Win32

..\configure -static -debug-and-release -platform win32-msvc2019 -static-runtime -ssl -openssl -openssl-linked -I %OPENSSL_HOME%\include -L %OPENSSL_HOME%\lib -opensource -confirm-license -opengl desktop -release -sql-sqlite -strip -qt-zlib -static-runtime -plugin-sql-sqlite -sql-sqlite -make tools -make libs -qt-pcre -qt-libpng -qt-libjpeg -qt-freetype -optimize-size -no-feature-d3d12

Notice that i did not use OPENSSL_LIBS because it keeps failing. I tried OPENSSL_LIBS="-LC:\OpenSSL-Win32\lib -lssl -lcrypto" but it failed. May be i am making it wrong !
I used Qt 5.13. The content of my make file and the contents of my config log is here

now i created a simple qml application with hello label. When i run the application i get "can not find libssl-1_1.dll, same for crypto-1_1.dll". This means it is linked dynamically. When i copy those files beside the binary it works, but i want to link it statically.

I tried many combinations. I am compiling with vs 2019 compiler ? does it make a difference if i compile the application with MinGW although Qt is compiled with nmake?

SGaist

You either have to copy the dlls in the same folder as your application or modify the PATH environment in the Run part of the Project panel of Qt Creator and add the folder where they are.

SherifOmran

but i don't want to deliver these files to the user? my try was to create a simple file that can be delivered to the user and that i uses TLS

SGaist

Then you have to also build OpenSSL statically.

If you want to have a 100% fully static application, you have to build all your libraries and their dependencies as static. Note that this is nothing Qt specific.

SherifOmran

As far as i understand, the file i downloaded from this link has a folder called lib inside it there is static where libcrypto.lib and libssl.lib and ossl_static.pdb exist. There is also another folder called engines-3.

Assume that these libraries are statically built. how can we link it to qt to compile it using these libraries.
This command failed

OPENSSL_LIBS="-LC:\OpenSSL-Win32\lib -lssl -lcrypto"

please download the file to see its content.
could you please correct it?

SherifOmran

Here is a solution and feedback to the people searching in future for same issue using openssl 1.1.1+ and at

guys the problem is as follows:
1- to compile it as static, you must use -openssl-linked parameter
2- but we think normally because we use the following parameters config will find the libraries.
-I %OPENSSL_HOME%\include -L %OPENSSL_HOME%\lib
but although these parameters are configured but config does not find the libraries and prints out the following error. It seems that these parameters are necessary only to find the header files and not to find the libraries

None of [libssl.dll.a libssl.a ssl.dll.a ssl.a ssl.lib] found in [] and global paths.
None of [libcrypto.dll.a libcrypto.a crypto.dll.a crypto.a crypto.lib] found in [] and global paths.

The solution to this is to add the path of these static libraries and openssl binary into your global PATH variable, this way it will find the .a libraries. I used Openssl 1.1.1

do the following for a quick test
where libssl.a
where openssl

if you get an output, so you can be sure it will work.
