New issue 2455: pypy3.3: building tests: environment variables CC etc - not honored
So I've finally successfully built pypy3.3 in Guix. Yay.
However, when I run the tests I get some failures. Turns out some of them are because ./ctypes_configure/cbuild.py and ./lib_pypy/_pypy_testcapi.py call [distutils.ccompiler.]new_compiler directly and nobody calls customize_compiler.
./ctypes_configure/cbuild.py: compiler = new_compiler(force=1)
./lib_pypy/_pypy_testcapi.py: from distutils.ccompiler import new_compiler
./lib_pypy/_pypy_testcapi.py: compiler = new_compiler()
After each of these new_compiler calls one should call distutils.sysconfig.customize_compiler. Otherwise the environment variables are not picked up.
What's more, _pypy_testcapi has a comment that this builds an extension. So why doesn't it build the extension using distutils build_ext ? If it did, all would work normally without having to call funny distutils internals.
What's more, ctypes_configure/cbuild.py has a homegrown compiler_command function which seems to do the same as customize_compiler would do, just with a weird name for the environment variable (PYPY_CC) and with less customizability. The file also contains another CCompiler class (in addition to distutils.CCompiler). Weird... is that left over from when there was no distutils in pypy?
