How to compile Qt webengine (5.11) on Windows with proprietary codecs
I had all of those problems for the last 5 days.
I'm doing a step by step instruction if you don't know how to begin with compiling Qt webengine (with or without proprietary codecs). If you have already done some of the steps, you can freely skip them.
Please if you see any error, if have one by doing this or if some instruction is not clear, tell me so I can update
1. Install Visual Studio 2017
Go to https://www.visualstudio.com/fr/downloads/ and download Visual Studio 2017.
When this window comes, check Desktop Development for C++ and be sure that VC++ toolset 2015.3v v14.00 (v140) and SDK Windows 10 (10.0.xxxxx.x) are checked.
Install and wait until it finishes.
2. Install Qt sources qt webengine
Open MaintenanceTool.exe present into the Qt folder
Add or delete module
Be sure to check at least: MSVC 2015 32-bit, MSVC 2015 64-bit, MSVC 2017 64-bit, Sources, Qt WebEngine
Install and wait until it finishes.
3. Install Qt webengine compile prerequisities
(Original instructions copied from Sébastien Bémelmans on this thread and a bit modified)
Download:
- Python 2 (2.7.15 actually, Python 3 is not supported) from https://www.python.org/downloads/windows/
- Perl (Strawberry vesion) from http://strawberryperl.com/
- Bison and flex from https://sourceforge.net/projects/winflexbison/ (Rename win-bison.exe to bison.exe and win-flex.exe to flex.exe)
- Gperf from http://gnuwin32.sourceforge.net/packages/gperf.htm
Be sure to add every .exe to System path, and restart the computer.
4. Compile Qt webengine with proprietary-codecs (or without)
Open cmd.exe (with administrator rights).
type cd + Path to the Microsoft Visual Studio folder where vcvarsall.bat is located:
cd "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build"
For compilation into 32-bits:
Type vcvars32.bat into command line
For compilation into 64-bits:
Type vcvars64.bat into command line
Go to the path where Sources of Qt are and enter qtwebengine subdirectory:
cd "C:\Qt\5.11.0\Src\qtwebengine"
For compilation into 32-bits:
Type "C:\Qt\5.11.0\msvc2015\bin\qmake.exe" -- -webengine-proprietary-codecs into command line (note the link is going to msvc 2015 32 bit)
For compilation into 64-bits:
Type "C:\Qt\5.11.0\msvc2017_64\bin\qmake.exe" -- -webengine-proprietary-codecs into command line (note the link is going to msvc 2017 64 bit)
Your console should look like this (32 bit):
And the result:
Now you need to call nmake. Type "Path to nmake.exe for version 32 bit or 64 bit" like this:
For compilation into 32-bits:
"C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.14.26428\bin\Hostx86\x86\nmake.exe" into command line (note the x86 into the path)
For compilation into 64-bits:
"C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.14.26428\bin\Hostx64\x64\nmake.exe" into command line (note the x64 into the path)
Your command line should now output a lot of things. Compiling qt webengine requires lot of memory and space (around 90 Go on my computer and 60% of my 8 GO of RAM). Be sure to have place and free memory. It is long processing too
