cannot install brotli bindings on Python 2.7 anymore

[jjnurminen]

Hi,

I cannot install brotli from PyPi any more, though seemingly it should still support Python 2.7. I can reproduce by creating a conda environment:

conda create -n py27 python=2.7

Saying pip install brotli first tells me to install Visual C++ from http://aka.ms/vcpython27. However, after installing that and trying again, I get the following during compilation:

 _brotli.obj : warning LNK4197: export 'init_brotli' specified multiple times; using first specification
       Creating library bin\temp.win-amd64-2.7\Release\c/common\_brotli.lib and object bin\temp.win-amd64-2.7\Release\c/common\_brotli.exp
    encode.obj : error LNK2001: unresolved external symbol _tzcnt_u64
    static_dict.obj : error LNK2001: unresolved external symbol _tzcnt_u64
    backward_references.obj : error LNK2019: unresolved external symbol _tzcnt_u64 referenced in function FindMatchLengthWithLimit

I'm on Windows 10, 64-bit Python. Any hints are appreciated.

Seems to be related to the fact that the Windows Python 2.7/AMD64 binary wheel is not on PyPi any more, so pip tries to build it from source (and fails).

The problem has been recently fixed. Soon I will make 1.0.10 release to fix this problem in PyPi

@eustas sounds good, thanks.

Hi,

I have the same problem by setting up esp-idf.
How did you fix the problem ? Which version of brotli ?

[jjnurminen]

@Antoine-Sc if you install brotli 1.0.7, you will still get the binary wheel.

Ok. It did not work for me. I'm trying to find out why

brotli 1.1 is out so this may be closed-fixed; if this issue is unexpectedly not fixed by this I'd suggest to close-not-planned as Python2 is much less relevant in 2024 than it was in 2020 and it would possibly useful to drop anything that is explicit done to support Python2.
