I'm writing a Ruby C Extension. I will be compiling it under Windows and OSX.
What I have been unable to work out is control where the makefile and all the rest of the generated files are placed.
My extconf.rb file got conditional statements for preparing the makefile depending on the OS - so I use one for both of them.
I would like that when I compile under OSX it is all placed in an osx folder and similary under a win folder under Windows in order to keep it all separated.
As it is now all the files are generated in the same folder as my source code.
(I am very green to C and compiling applications. sorry if I have missed something obvious.)
I could write a batch to move the files afterwards, but I find it cleaner if it could be done during generation.
I looked at the source of mkfm.rb and found that if you changed the current directory the Makefile was the current one.
Dir.chdir( OUTPUT_PATH )
create_makefile( EXTENSION_NAME, SOURCE_PATH )
That created the makefile in OUTPUT_PATH. As you see, I then had to provide SOURCE_PATH to create_makefile to account for the face the Makefile wasn't in the same location as the source files.
