Masayuki Yamamoto added the comment: I found -L option addition at Lib/distutils/command/build_ext.py:222. This place is a process that finalize options for the build_ext command. Comment in there: for extensions under Cygwin and AtheOS Python's library directory must be appended to library_dirs
After that I searched Makefile rule for installing $(LDLIBRARY) into "$(prefix)/lib/python3.5/config-3.5m" to look for way of simplifying code. And I came across the $(LIBPL) configuration variable that is used by installation of the configuration for building library. Hence I made a patch that adds to library_dirs the $(LIBPL) configuration variable instead of the "$(prefix)/lib/python$(VERSION)/config". I succeeded to build '_speedups' C extension module of simplejson using new python that is applied this patch. Erik, Would you be able to verify this patch?
