Compile Qt 5.13.2 with QtWebEngine issue

[Cobra91151]

@Christian-Ehrlicher

Hello!

Actually, there is no error it just skips to build the QtWebEngine when building Qt (all modules). When building QtWebEngine separately it displays only these issues, which I have added in the previous post and in the bug report.

ninja: build stopped: subcommand failed.
jom: C:\QtBuild\QtWebEngine\src\core\Makefile.gn_run.Release [run_ninja] Error 1
jom: C:\QtBuild\QtWebEngine\src\core\Makefile.gn_run [release] Error 2
jom: C:\QtBuild\QtWebEngine\src\core\Makefile [sub-gn_run-pro-make_first] Error 2
jom: C:\QtBuild\QtWebEngine\src\Makefile [sub-core-make_first] Error 2
jom: C:\QtBuild\QtWebEngine\Makefile [sub-src-make_first] Error 2

For x64 everything compiles well, I think the problem is with ninja path when using x64_x86 Cross Tools Command Prompt for VS. I will try to use the system ninja from VS 2019. Thanks.

I have added the ninja path from VS 2019 to environment variable, but it still skips QtWebEngine build and no error is printed:

In the config.log file I found the following errors:

Qt 5.13.2 compiles successfully, but for some reason it automatically skips the QtWebEngine build.

[Cobra91151]

I have checked the config.log from x64 compilation and it displays the same errors but QtWebEngine compiles successfully. I think, something is missing for x86.

I think, it could be the issue with the latest Windows 10 version 1909 build 18363.476, because it uses Win Dev Kit 18362.1, Qt 5.13.2 was released: October 31, 2019. So, I think, it was built on previous Win 10 version 1903. I will try tomorrow to build it on VM.

Could you share how build qt with mysql?
You have a topic about how to build qt with mysql , but it need separately build Openssl and mysql libs .
Now QT5.13.2 has include OPENSSL , do you have simply build steps for qt with mysql? (or mariadb)

Hello!

Currently, I am busy. I am working to fix the Qt 5.13.2 QtWebEngine build issue for x86 architecture.

I want to combine mysql-5.7.28 with the latest openssl-1.1.1d and QtWebEngine. Qt 5.13.2 has older OpenSSL included. You can contact me in the chat, so we can discuss it.

[Cobra91151]

I have checked it on VM on Windows 10 version 1903, but it still skips to build QtWebEngine when building Qt 5.13.2. I think, there is a bug. I will try to build Qt 5.12.X LTS and check if it compiles or not.

[Cobra91151]

I have tried to build Qt 5.12.6 LTS with QtWebEngine but the same issue is present for x86 architecture using x64_x86 Cross Tools Command Prompt for VS. It compiles Qt and skips the QtWebEngine build. I will switch back to Qt 5.9.8 LTS.

[Cobra91151]

Ok. The problem was that older Qt 5.9.8 mixed up with Qt 5.13.2 because I had added paths for Qt 5.9.8 in the PATH environment variable. I have removed these paths and built Qt and then built QtWebEngine module separately, because it still skips QtWebEngine module when building all Qt modules. Anyway, I have figured it out and now it is all working except for the windeployqt.exe utility, it is missing. Any ideas where to get or how to build the windeployqt.exe? Thanks.

[Cobra91151]

So, I have found that windeployqt.exe utility is actually built (it is exists in the ..qttools\bin directory) but for some reason it does not copy to the appropriate directory when I run jom install command.

[Cobra91151]

Ok. I have compiled Qt 5.13.2 for x86 successfully. I have built some tools separately, because it skips them or just do not copy to the appropriate directory using jom install command. It is strange, because when building for x64 architecture all tools are built and copied correctly. Anyway, now I have Qt 5.13.2 for msvc2017, msvc2017_64, msvc2019, msvc2019_64.
