When I try to build PyPy with MinGW, I get the following: [translation:info] Translating target as defined by targetpypystandalone Traceback (most recent call last): File "../../rpython/bin/rpython", line 20, in <module> main() File "D:\eclipse-php-2022-06-R-win32-x86_64\Projects\pypy-release-pypy3.10-v7.x\rpython\translator \goal\translate.py", line 219, in main targetspec_dic, translateconfig, config, args = parse_options_and_load_target() File "D:\eclipse-php-2022-06-R-win32-x86_64\Projects\pypy-release-pypy3.10-v7.x\rpython\translator \goal\translate.py", line 155, in parse_options_and_load_target targetspec_dic = load_target(targetspec) File "D:\eclipse-php-2022-06-R-win32-x86_64\Projects\pypy-release-pypy3.10-v7.x\rpython\translator \goal\translate.py", line 97, in load_target mod = __import__(specname) File "targetpypystandalone.py", line 7, in <module> from pypy.interpreter import gateway File "D:\eclipse-php-2022-06-R-win32-x86_64\Projects\pypy-release-pypy3.10-v7.x\pypy\interpreter\g ateway.py", line 19, in <module> from pypy.interpreter.eval import Code File "D:\eclipse-php-2022-06-R-win32-x86_64\Projects\pypy-release-pypy3.10-v7.x\pypy\interpreter\e val.py", line 6, in <module> from pypy.interpreter.baseobjspace import W_Root File "D:\eclipse-php-2022-06-R-win32-x86_64\Projects\pypy-release-pypy3.10-v7.x\pypy\interpreter\b aseobjspace.py", line 6, in <module> from rpython.rlib import jit, types, rutf8 File "D:\eclipse-php-2022-06-R-win32-x86_64\Projects\pypy-release-pypy3.10-v7.x\rpython\rlib\rutf8 .py", line 26, in <module> from rpython.rlib.unicodedata import unicodedb File "D:\eclipse-php-2022-06-R-win32-x86_64\Projects\pypy-release-pypy3.10-v7.x\rpython\rlib\unico dedata\__init__.py", line 4, in <module> from rpython.rlib.unicodedata import unicodedb_5_2_0 as unicodedb File "D:\eclipse-php-2022-06-R-win32-x86_64\Projects\pypy-release-pypy3.10-v7.x\rpython\rlib\unico dedata\unicodedb_5_2_0.py", line 6, in <module> from rpython.rlib.unicodedata.supportcode import (signed_ord, _all_short, File "D:\eclipse-php-2022-06-R-win32-x86_64\Projects\pypy-release-pypy3.10-v7.x\rpython\rlib\unico dedata\supportcode.py", line 2, in <module> from rpython.rtyper.lltypesystem.rffi import r_ushort, r_short File "D:\eclipse-php-2022-06-R-win32-x86_64\Projects\pypy-release-pypy3.10-v7.x\rpython\rtyper\llt ypesystem\rffi.py", line 515, in <module> sizeof_c_type('__int128_t', ignore_errors=True) File "D:\eclipse-php-2022-06-R-win32-x86_64\Projects\pypy-release-pypy3.10-v7.x\rpython\rtyper\too l\rfficache.py", line 38, in sizeof_c_type return sizeof_c_types([c_typename], **kwds)[0] File "D:\eclipse-php-2022-06-R-win32-x86_64\Projects\pypy-release-pypy3.10-v7.x\rpython\rtyper\too l\rfficache.py", line 47, in sizeof_c_types assert len(lines) == len(typenames_c) AssertionError It seems as if the ask_gcc function is broken for MinGW, and I can't tell why at a first glance. Is a fix possible?
