Error while building qt 5.9 with openssl statically using VS2015

[Antiver]

I ran configure successfully using the following command:

configure -static -debug-and-release -prefix “C:\Qt\Qt5.9.2\static_with_openssl” -platform win32-msvc2015 -qt-zlib -qt-pcre -qt-libpng -qt-libjpeg -qt-freetype -opengl desktop -sql-sqlite -sql-odbc -openssl-linked OPENSSL_PREFIX=C:\QtOpenSSL -I "C:\QtOpenSSL\include\openssl" -L "C:\QtOpenSSL\lib" -opensource -confirm-license -make libs -nomake tools -nomake examples -nomake tests

it shows

  OpenSSL ................................ yes
    Qt directly linked to OpenSSL ........ yes

but when I ran nmake, it shows:

Could you please tell me how to solve this problem?
Thanks!

Hi and welcome to devnet,

What version of OpenSSL did you download ?

[flouwet]

Same issue, we used openSSL 1.0.2L

[SGaist]

Are you linking against a version of OpenSSL that is from the correct architecture ? And built using the same compiler ?

[flouwet]

Yes, but i think the following commit is breaking my build.
https://code.qt.io/cgit/qt/qtbase.git/commit/src/network/ssl/ssl.pri?id=5e2367aaa5137f27c722cd7f8474696b0fbaa099

[SGaist]

Can you confirm that reverting it allows to build Qt statically with OpenSSL again ?

[flouwet]

I've got the build working with following patch.

@flouwet @SGaist how do I apply this patch?

[mcpp]

@flouwet I'm getting error: corrupt patch at line 33 when I save this patch in notepad++ and apply using git

[SGaist]

@mcpp
There are several patches here, which one didn't apply correctly ?

[mcpp]

@SGaist I copied the patch from the window. Here is what I brought to the editor. Its says corrupt patch at line 33. I assume I'm just doing something wrong. Any advice?

[SGaist]

You didn't do something wrong. The files the original patches were applied to changed in between.

You can also simply compare the content of the files with the modifications and apply them by hand.

[mcpp]

@SGaist Okay I'll try that. Thanks for your help and amazing contribution to this source.

@SGaist Okay It seems to be getting a bit further, however I am getting this error now:

Any ideas? I'm building with VS2015.

[SGaist]

Might be a silly question but: are you sure you are building in 64 bit mode ?

[mcpp]

I am. I think its a version compatibility issue with ssl. It should be built with vs2015. Even though those say 32MT, I think the problem is that they are built with vs2013. I built these with vs2015 and tried again, and got these:

Qt5Network.lib(qsslsocket_openssl_symbols.obj) : error LNK2019: unresolved external symbol sk_num referenced in function "int __cdecl q_sk_num(struct stack_st *)" (?q_sk_num@@YAHPEAUstack_st@@@Z)

And about 500 others.

What libs should I be building using vs2015 for openssl?

[SGaist]

Well, OpenSSL itself.

You can't mix and match C++ libraries built with different compilers on Windows. The only exception currently is VS2017 which is backward compatible with VS2015.

[LSIDev]

Had the same unresolved errors by using Visual2017, Qt5.9.8, having an own compiled static OpenSSL-libs, so this could not be the mentioned compatibility problem.
Lately I found out that the unresolved was not caused by linking the Qt5Network.lib, because this was already created on the disk. The lib that caused the error was the xmlpatters-lib, and when I removed it from compiling by using -skip xmlpatterns in the config command, everythign went fine!
So my final command was

C:\Qt\Qt5.9.8\5.9.8\Src\configure.bat -release -static -static-runtime -prefix C:\Qt\Qt5.9.8_static_ssl −opengl desktop -skip webengine -skip xmlpatterns -nomake tests -nomake examples -openssl -openssl-linked -I C:\OpenSSL\include -L C:\OpenSSL\lib

by having the three environment variables OPENSSL_LIBS, OPENSSL_LIBS_DEBUG and OPENSSL_LIBS_RELEASE already set via windows system settings. Setting them directly in the command line caused syntax errors (probably only supported by earlier Configure-versions?)
