I cannot compile docs

[0xFF1E071F]

What did you do?

I am creating a linux package for PisiLinux of pillow 7.1.1. I can compile pillow with no problems. I cannot compile docs.

What did you expect to happen?

Creating html documentation.

What actually happened?

Building of documentation finished with problems, 7 warnings, then stop.

What are your OS, Python and Pillow versions?

• OS: PisiLinux 2.1.2
• Python: 3.8.2
• Pillow: 7.1.1
• Sphinx: 3.0.0

def build():
    # suppress warnings
    pisitools.cflags.add("-Wno-sign-compare -Wno-pointer-sign")
    # fix unused direct dependency analysis
    shelltools.export("LDSHARED", "x86_64-pc-linux-gnu-gcc -Wl,-O1,--as-needed -shared -lpthread")
    pythonmodules.compile(pyVer="3")
    
    # build documentation
    shelltools.export("PYTHONPATH", "%s/Pillow-%s/build/lib.linux-x86_64-3.8" % (get.workDIR(), get.srcVERSION()))
    shelltools.system("make -C docs html")

And This was the error:

Looks like #4528 (comment).

You could try Sphinx < 3, or patch using f1f177c, or we may have a 7.1.2 out soonish with the fix: #4354 (comment).
