Fixing #includes <> for GCC (Code::Blocks)

I am working with some code that was written for a different compiler/linker, a开发者_如何学编程nd it is including files like this:

#include <Engine/Graphics/Sprite.h>

from anywhere in the project.

The project contains such a file at that path (from the root of the project), but when I build I get the file not found error.

How can I fix all of these includes, without going through and doing it all manually?

I'm not quite sure if I understand your explanation, what do you mean with "from the root of the project". But well...

When you use the #include directive with <> what your are telling the compiler is to look for the the file on the Directories you include with -I option.

In code blocks go to Project->Build Options->Search Directories->Compiler

And add the folder path to the folder containing "Engine".

You can find more info here http://msdn.microsoft.com/en-us/library/36k2cdd4(v=vs.71).aspx

Edit: Before trying anything, try #include "path/somefile.h" instead of #include <pathsomefile.h>

Probably you should write

#include "Engine/Graphics/Sprite.h"

(notice the double quotes instead of the brackets).

In #include directives brackets are used to specify that you want to include a system/library header file, that will be searched in the system includes directory (e.g. /usr/include), while the double quotes are used to include files in the current path.

This should work if the files that use this #include are in the directory that contains the Engine/... hierarchy. If that's not the case, you should also specify it to the compiler as an additional include directory, with the -I directive.

Please remember that one usually uses #include <filename> directive to include files from standard include catalogues. These catalogues defined as environment variable or in command line of compiler. And #include "filename" to include header file from current directory or any path relative to current directory.

without going through and doing it all manually?

You may use search&replace feature of your favourite editor

I'm going to copy Ben's comment and say you should add an include path to where your header files are located. This is very common to do in a project
