How to find out cl.exe's built-in macros
(7 answers)
Closed 6 years ago.
Is there a cl.exe option to dump all the pre-defined Macros ( along with the defined values ).
Something like gcc -dM -E - < /dev/null for gcc.

Answer 1

Unfortunately, I don't think MSVC has a built in way of doing this.
I've used the following program to dump values of 'known' predefined symbols. I should give attribution (because I know I didn't come up with this), but I don't have notes on where I got it from (update: looks like I probably got it from here: http://social.msdn.microsoft.com/Forums/en-US/vclanguage/thread/644c12ed-e3a7-4c5a-a73a-610fcc7913ca)...

I don't see that option in the MSDN documentation, but the list of predefined macros for Visual Studio 2008 and 2010 are available.
