[Snowball-discuss] Building of PyStemmer module failed (fix included)

[Marijn van Vliet]

When trying to install the Python wrapper (PyStemmer), the install process  
fails on windows with a slew of messages:

build\temp.win32-2.7\Release\libstemmer_c\libstemmer\libstemmer_utf8.o:libstemmer_utf8.c:(.text+0x18e):  
undefined reference to `SN_set_current'
build\temp.win32-2.7\Release\libstemmer_c\libstemmer\libstemmer_utf8.o:libstemmer_utf8.c:(.data+0x8):  
undefined reference to `danish_UTF_8_create_env'
build\temp.win32-2.7\Release\libstemmer_c\libstemmer\libstemmer_utf8.o:libstemmer_utf8.c:(.data+0xc):

build\temp.win32-2.7\Release\libstemmer_c\libstemmer\libstemmer_utf8.o:libstemmer_utf8.c:(.data+0x10):

<snip>

This is caused by a bug in setup.py, which fails to find all required .c  
files. A possible fix would be to change line 24 from:

     and os.path.split(line.strip())[0] in library_core_dirs]

to:

     and os.path.split(line.strip().replace(' \\', ''))[0] in  
library_core_dirs]

regards,
Marijn.
