How to set predefined macros in Code::Blocks

Question

Is there a way to set some predefined Macros for my local installation of Code::Blocks.

To elaborate on that, basically I would like to have certain blocks compiled only at pc and not anyplace I send the code to. One way to achieve this is as follows:

#define MYPC
#ifdef MYPC
 //do something
#else
 // do something else
#endif

I was to achieve the same thing, but I don't want to include the line #define MYPC and woud like to add this somewhere in the IDE. I know how to do this in Visual Studio, and I think it also exists in Code::Blocks as well. Thanks.

Project - Properties - Project's build options - Compiler Settings - #defines.

Edit. Example of #defines edit box:

CONSTANT1
CONSTANT2="0"

Gives the following command line:

g++ -DCONSTANT1 -DCONSTANT2="0" ...

Thanks for the reply. Do I just write each #defines per line? – Shamim Hafiz - MSFT Nov 01 '10 at 08:08
Yes, every constant must start from new line. – Alex F Nov 01 '10 at 09:08

I have successfully defined macros in Project options and compiled ok, but in the editor of code blocks, it does not highlight correctly. – Sswater Shi Sep 05 '13 at 01:30
@SswaterShi Hmm, it looks like the editor won't parse the build specific `#defines` readily. It is still a missing feature in CB(almost after 6 years you posted the above comment). – sjsam May 11 '19 at 04:16
