Want to compile the rmagick-1.9.3 on win32 to get the latest version  
intstead of the pre-compiled gem :).

after run,  
ruby extconf.rb --with-rmagic-dir=path to the ImageMagick dir  
I could get the makefile, but when compile, the following eror come  
out,

RMagick-1.9.3\ext\RMagick\rmagick.h(114) : error C2371: ‘boolean’ :  
redefinition; different basic type

Have looked through the documentation, seems like no info on how to  
compile on win32?  
Any help? Thanks!

The windows.h file already defines a “boolean” type, so that would  
explain the error. Try adding this to the extconf.rb file:

have\_type(“boolean”)

Then, within rmagick.h, surround line 114 with “ifndef HAVE\_TYPE” and  
“endif”.

I don’t know if that’s the only issue, but it should solve that one at  
least.

Oh, it looks like there is no extconf.rb file. Just comment out lines  
109-114 and see how it goes.
