turn a command line string into a #define

I'd like to take a string passed in on the command line and turn it into a #define.

The string passed in will always start with SKU and then be followed by platform/sku combination. Examples:

-sSKU_360_WW=1
-sSKU_PS3_US=1

I could manually code individual skus in my jam rules file:

if $(SKU_360_WW) = 1
{
            C.Defines $(TARGETS) : SKU_360_WW ;
        }

if $(SKU_PS3_US) = 1
{
            C.Defines $(TARGETS) : SKU_PS3_US ;
        }

but I was hoping to find a more generic solution (which didn't require knowledge of every single sku in advance)

Any help appreciated.

RE: turn a command line string into a #define - Added by Joshua Jensen about 1 year ago

There is no support for this right now, but you could attempt to add support to collect these variables in src/jam.c and src/variable.c.

In src/jam.c, find:

/* Load up variables set on command line. */

That is where the variables are set that come in on the command-line. Within the function var_defines, the symbol is split into its key/value pair. At that point, you could add the key name to a LIST and then run var_set() after everything is done.

This is a good idea, and I would like to see it implemented. I don't have much time right now to do so and fully test it.

Thanks!
