This results in the following moc command being issued:

    @"bin/gcc-4.9.2/debug/threading-multi/moc_calculatorform.cpp.rsp"


*This call will hang indefinitely*.

It seems the issue is *due to the -f flag*. If I edit the moc action in qt5.jam to remove the -f, then it works

That is, I edit this:

    actions moc
    {
         $(.BINPREFIX[-1])/moc -f $(>) -o $(<) @"@($(<).rsp:E=-D$(DEFINES)$(.nl) -I$(INCLUDES:T)$(.nl))"
    }


so it looks like this (note missing -f):

    actions moc
    {
         $(.BINPREFIX[-1])/moc $(>) -o $(<) @"@($(<).rsp:E=-D$(DEFINES)$(.nl) -I$(INCLUDES:T)$(.nl))"
    }

Hi Steve,

could it be that you have old version of Boost.Build. Looking at the current version, I don't see -f option:

Thanks,
