Comeau compiler ? Of course it exists. What do you mean by Comeau toolset
for V2 ? Do you mean that bjam V2 does not support the toolsets that bjam V1
supports ? If this is the case, certainly it should be documented.

I had not realized that at all. I never dreamed that the bjam V2 command
line syntax was incompatible with bjam V1. I am surmising now that one is
really not supposed to be using bjam V2 at all yet, or that the
documentation for using bjam V2 is incomplete. I naturally assumed that bjam
V2 was usable, given the Jamfile.V2 files for each Jamfile.

Yes, exactly.

OK, evidently the way to use bjam V2, from the user's point of view, is
different from bjam V1. I naively assumed that bjam V2 would support the
same command line syntax as bjam V1 in ordser to be backward compatible. I
have now looked at Boost.Build V2 User Manual. It appears much more
complicated to use than V1 but I will follow the suggestion above and see if
I can build it correctly. Thanks for the info !

I have the latest bjam executable for Windows from sourceforge. Does this
not support V2 ?
