Re: [Boost-build] testing.capture-output actions too long (max 2047):

Correct me if I am wrong, but does this mean the 'run' rule cannot be 
used on large source trees?

(The unit-test rule is much simpeler and most likely will work, but then 
I cannot pass argv to my test executable, and not surprisingly, it's 
sort of needed.)

But maybe it's another question (and I am no bjam expert), I notice the 
'set' command growing very large on each evocation of bjam in the tree:

/src
    /a
    /b
    /c
    /d

by the time bjam reaches d ('src' has a jamfile with build-project a, b 
etc), the set command has grown to 'set a/bin/...;b/bin/...;c/bin/...' 
but d and a are not related, so why does it grow?

I thought maybe some variable is not cleared, is gobal or ... so I added 
the following line to the run-path-setup rule

  PATH_SETUP on $(target) = "" ;

before the original line, but it does not help.

Is there anything I can do to fix it?

Regards, Dirk
