Christoph Gohlke added the comment: This change broke all my builds that link statically against 3rd party libraries built with the `/MD` flag. `/MD` was used at least since Python 2.3 and is the default for static libraries in Visual Studio 2015. Some of the broken builds: lxml, pillow, matplotlib, pygame, pycuda, pymssql, netcdf4, GDAL, psycopg2, pycurl, gmpy, and pyopenssl. All of these packages built OK with Python 3.5.0b4.
The build errors are of this kind: `error LNK2001: unresolved external symbol __imp_memchr` `error LNK2001: unresolved external symbol __imp_strstr` The linker throws the following warning: `LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library` ---------- nosy: +cgohlke _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue24798> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
