Trying to build cefpython v66 upstream on windows
using spotify build cef_binary_3.3359.1774.gd49d25f_windows32.tar.bz2
copied src\version\cef_version_linux.h to mac.h and win.h
python ../tools/automate.py --prebuilt-cef
returns warning/error (part of console output)

Currently only Linux builds of v66 were tested and do work fine. You will have to wait a few more days for Windows.

Current master builds and runs fine on Windows. The v66-upstream release was updated with Windows 32-bit prebuilt binaries.
I couldn't reproduce your issue, there might be something wrong with your environment.

I just tried to rebuild from spotify but got the same error.
in the source code I don't find any difference compared to 2 days ago
also the src/version/cef_version_win.h still contains the old #define CEF_VERSION "3.3029.1604.g364cd86"
My build platform is Win 10 64 bit using python 2.7.11

I used the zip / tag.tz on https://github.com/cztomczak/cefpython/releases/tag/v66-upstream
Which was not updated, I will re-build using your recent update on GIT https://github.com/cztomczak/cefpython.git
and let you know the result.

rebuild using git master and spotify cef_binary_3.3359.1774.gd49d25f_windows32.tar.bz2
python ../tools/automate.py --prebuilt-cef seems to build ok
however
python ../tools/build.py 66.0
failed with
Exception: Windows SDK Lib directory not found: C:\\Program Files\\Microsoft SDKs\\Windows\\v7.1\\Lib
[build.py] Cleanup: remove pyx files in build_cefpython/
[build.py] ERROR: failed to build the cefpython module
my windows SDKs v71.A is in c:\Program Files (x86)\Microsoft SDKs\Windows
any suggestion to fix my environment?
Attached build_error.zip complete console output (see at the end)

Follow the build instructions document - requirements. You need either SDK 7.0 or 7.1. You have 7.1A which is different. See https://wiki.python.org/moin/WindowsCompilers

many thanks,
After 'Microsoft Visual C++ 10.0 standalone: Windows SDK 7.1 (x86, x64, ia64)' instructions build succeeded.
Also python ../tools/make_installer.py xx.xx --wheel --universal succeeded
however this contains a python 2.7 only
Any instructions how to create a cefpython_py36.pyd?

You have to run the build.py script with Python 2.7, then run that same script using Python 3.6. After that run the make-installer.py script and it should include both modules.

building cefpython3-66.0-py2.py3-none-win32.whl succeeded ;)
One more question.
I've already rebuild chromiumembedded https://bitbucket.org/chromiumembedded/cef/wiki/MasterBuildQuickStart.md using build=true proprietary_codecs
How to implement these in the cefpython?
Can I just copy dll files?

CEF master branch is not supported, it would likely require modifications to cefpython source codes (which might not be easy).

Find the chromium/src/cef/cef_binary_*/ directory or archive that was created during build. This is the same binary as from the Spotify builds, so the same instructions apply.

It's best to build CEF from sources with cefpython's automate.py tool, as it defines some flags and on Linux applies special patch. However on Windows, I think it should work fine if you followed upstream CEF build instructions.

If have copied my compiled dll, dat, bin, pak and locales and swiftshader\*.dll to build\cef66_3.3359.1774.gd49d25f_win32\bin\
then build again using python ../tools/build.py 66.0
seem to work all fine (except tkinker_.py does hangs when closing in python 2.7, works in 3.6)
mp4 working
Many thanks,
Luc

You shouldn't be copying any files manually, instructions are clear.

OK I will try the cefpython's automate.py tool.
