thank you very much!!
but I have some problem in using the variable.
If I want to set the directory by using $(CODEBLOCKS )to C:\program files\CODEBLOCKS\personal_include,
(my code::blocks program dirctory is C:\program files\CODEBLOCKS)
I set the follow :(Build Options->Directorys->compiler)
$(CODEBLOCKS)\personal_include
after the building , the compiler tell me it can't find directory / file.
$(CODEBLOCKS) == "C:\program files\CODEBLOCKS" ??
I'm confused... :?
--
By the way,
(Build Options->Custom variables)
I set the Variable $(CODE) = "c:\program files\CODEBLOCKS"
and change the path to the follow:
$(CODE)\personal_include
No error.
