Problems compiling Ruby extension in MSVC

Ruby
1

I am trying to compile my ruby extension under Windows with the MSVC
compiler shipped with Visual Studio 2003. I have followed the steps
outlined here:

http://www.koontzfamily.org/david/blog/?p=230

However on doing nmake I get the following errors:

cl : Command line warning D4024 : unrecognized source file type
‘files/ruby/lib/ruby/1.8/i386-mswin3
2’, object file assumed
cl : Command line warning D4027 : source file
‘files/ruby/lib/ruby/1.8/i386-mswin32’ ignored
cl : Command line warning D4024 : unrecognized source file type
‘files/ruby/lib/ruby/1.8/i386-mswin3
2’, object file assumed
cl : Command line warning D4027 : source file
‘files/ruby/lib/ruby/1.8/i386-mswin32’ ignored
Test.c
Test.c(1) : fatal error C1083: Cannot open include file: ‘ruby.h’: No
such file or directory
NMAKE : fatal error U1077: ‘cl’ : return code ‘0x2’
Stop.

It seems that the compiler does not like spaces in the include path (My
ruby install directory is D:\Program files\ruby). Is there any better
way of getting extensions to work under windows?

The ruby.h file is present at D:/Program
files/ruby/lib/ruby/1.8/i386-mswin32.

thanks,

It seems that the compiler does not like spaces in
the include path (My ruby install directory is
D:\Program files\ruby).

Try wrapping the path in quotes for example:

“D:\Program files\ruby”

It seems that the compiler does not like spaces in the include path (My
ruby install directory is D:\Program files\ruby).

I too have spaces in my include path, and it works ok. I thought I had
to
surround the path with "-signs, but for the SET commands they created
trouble.

So I run:

ruby extconf.rb -with-ruby-include=“C:\ruby\src\ruby-1.8.2;C:\Program
Files\Microsoft Visual Studio .NET 2003\Vc7\include;C:\Program
Files\Microsoft Platform SDK\Include;”

set INCLUDE=C:\Program Files\Microsoft Visual Studio .NET
2003\Vc7\include;C:\Program Files\Microsoft Platform SDK\Include;
set LIB=C:\Program Files\Microsoft Visual Studio .NET
2003\Vc7\lib;C:\Program Files\Microsoft Platform SDK\Lib
