http://bugzilla.opensuse.org/show_bug.cgi?id=1206107 Bug ID: 1206107 Summary: i686-w64-mingw32-g++ and x86_64-w64-mingw32-g++ reporting incorrect default include paths for C++ Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Major Priority: P5 - None Component: Development Assignee: screening-team-bugs@suse.de Reporter: spartanj@gmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/108.0.0.0 Safari/537.36 Build Identifier: Hi. I usually cross-build an application with mingw32 and mingw64 and have no problems, but since a couple of weeks ago I'm not able to build the application because any standard library include in my C++ code will produce errors. The error seems to be that the compiler is looking in the wrong places to build the code. I always get a similar error like: x86_64-w64-mingw32-g++ -O2 -g -pipe -Wall -fexceptions --param=ssp-buffer-size=4 -mms-bitfields -MD -MP -DDEBUG -DEE_DEBUG -DEE_MEMORY_MANAGER -m64 -g -B /usr/bin/x86_64-w64-mingw32- -Wall -o "../../obj/windows/x86_64/debug/pugixml-static/pugixml.o" -MF "../../obj/windows/x86_64/debug/pugixml-static/pugixml.d" -c "../../src/thirdparty/pugixml/pugixml.cpp" In file included from /usr/include/c++/12/exception:37, from ../../src/thirdparty/pugixml/pugixml.hpp:31, from ../../src/thirdparty/pugixml/pugixml.cpp:17: /usr/include/c++/12/x86_64-suse-linux/bits/c++config.h:3:10: fatal error: bits/wordsize.h: No such file or directory 3 | #include | ^~~~~~~~~~~~~~~~~ compilation terminated.

This was not the case a few months ago. Reproducible: Always Steps to Reproduce: 1. Try to cross-compile any C++ file with mingw32 or mingw64 Actual Results: Include file error Expected Results: Successful compilation -- You are receiving this mail because: You are on the CC list for the bug.
