Subject: Re: extending ruby with c++ on windows

Thank you for answers. it was good idea.
but i still have problems.
i installed ruby in folder without spaces. relaunched "ruby extconf.rb" 
and "make" than, as in tutorial. executing "make" with version 3.80 i 
got the same error as before (makefile:145: *** target pattern contains 
no `%'.  Stop.). building with "make" with version 3.81 i got next 
message:
mingw32-make: *** No rule to make target 
`/C/Ruby19/include/ruby-1.9.1/ruby.h',
needed by `Welcomer.o'.  Stop.
i fixed in makefile row with path (corrected "/C/" to "C:/") and got 
this response:
C:\temp\c2r>mingw32-make
process_begin: CreateProcess(NULL, rm -f Welcomer.so, ...) failed.
make (e=2): ═х єфрхЄё  эрщЄш єърчрээ√щ Їрщы.
mingw32-make: [Welcomer.so] Error 2 (ignored)
g++ -shared -s -o Welcomer.so Welcomer.o -L. -LC:/Ruby19/lib -L. 
-Wl,--enable-a
uto-image-base,--enable-auto-import   -lmsvcrt-ruby191  -lshell32 
-lws2_32

As i understand, error 2 means "The system cannot find the file 
specified".

This command generates two files: "Welcomer.o" and "Welcomer.so". One 
more question is "is it normal that make generates .so file? maybe .dll 
will be more suitable".
