There is an issue with building Qt 5.12.4 (32 bit) with enable proprietary codecs. Linked against OpenSSL 1.1.1 installed from Qt online installer. Platform Windows 10 x64, used Visual Studio 2017 Community Edition. Additionally installed git, flex, bison, gperf, Strawberry Perl. Configured with commands:
call "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvarsall.bat" amd64_x86
SET _ROOT=C:\Qt-build\qt5
SET PATH=%_ROOT%\qtbase;%_ROOT%\qtbase\bin;%_ROOT%\gnuwin32\bin;C:\Qt\Tools\QtCreator\bin;%PATH%;C:\Program Files\Git\usr\bin
SET PATH=%_ROOT%\qtrepotools\bin;%PATH%
SET _ROOT=
SET PATH=C:\Python27;%PATH%
C:\Qt-build\qt5\configure -webengine-proprietary-codecs -shared -opensource -platform win32-msvc -nomake tests -nomake examples -confirm-license -prefix C:\Qt\5.12.4\msvc2017_32 -openssl-linked -I c:\Qt\Tools\OpenSSL\Win_x86\include -L c:\Qt\Tools\OpenSSL\Win_x86\lib OPENSSL_LIBS="libssl.lib libcrypto.lib"
After run build
nmake
Build started. And after finish run install:
nmake install
cd qtwebengine
nmake install
All build and installation without visible errors.
When I build example simplebrowseragainst Qt from C:\Qt\5.12.4\msvc2017_32 (copied SSL libs from c:\Qt\Tools\OpenSSL\Win_x86 to executable directory) it fails on start (any opening or refresh page) with message box
Any help is appreciated.
