[New-bugs-announce] [issue25250] AttributeError: 'MSVCCompiler' object has no attribute '_MSVCCompiler__version'

[Matt Hickford]

New submission from Matt Hickford:

Hi distutils. I wrote a setup.py that conditions on compiler type, following the guide at [1]. I needed to add an extra include when the compiler is an msvc version older than 9.0 (infamously missing stdint.h [2])

Anyway the code I wrote to do this was:

if self.compiler.compiler_type == "msvc" and int(self.compiler._MSVCCompiler__version) <= 9:

Which worked fine on all Python versions (tested 2.7 through 3.4) UNTIL the recent release of Python 3.5. On Python 3.5 I get the error:

AttributeError: 'MSVCCompiler' object has no attribute '_MSVCCompiler__version'

Oh no. My fault I suppose for relying on a private variable. Can you suggest a more reliable way to test "compiler is msvc <= 9.0"? The test should be compatible all Python versions 2.7 through 3.5 so it can safely go in a setup.py

Can you help?
