Re: How to pass a definition on the bjam command line

Just in case anyone has this problem again, I thought on leaving a
quick note on how I resolved it for the time being.

In the Jamfile of my project I created a couple of new variants:

variant my_debug : <variant>debug <define>NO_MAYA_GUI ;
variant my_release : <variant>release <define>NO_MAYA_GUI ;

then I can build then like

bjam --v2 variant=my_debug 

Unfortunately if you use a bjam lower than 3.1.11 I found the problem
than some command line flags are not processed. Like this:

bjam --v2 variant=my_debug --clear

will not clear the build targets, while this

bjam --v2 debug --clear 

will work. So seems pretty clear it is a bug on the older versions of
bjam. Anyhow bjam 3.1.11 is working so far. It would be nice if one
could easily pass definitions on the command line without creating
variants, like it is the case with the bbv1, unfortunately I am not
getting any means to do that on bbv2.
