Another OpenVMS question

Hi all,

I originally posted to the Jamming mailinglist, but got no response. I
figured the behaviour of bjam might still be the same with respect to
OpenVMS paths.

Hi,

it seems to be impossible to get both jam (2.4) and the DEC C++ 6.5 compiler
(cxx) to locate the header files correctly when using relative includes
under OpenVMS, e.g.:

--- snip from whoever.cpp ---
#include <Whatever/Whoever.h>

To get cxx to find the headers, I created a logical root for the include
root, e.g.:

def/job/trans=conc INC_ROOT "DISK$USER:[MYDIR]"

Then I can use this in a unix-style path to cxx, e.g.:

cxx /INCLUDE_DIR=("/inc_root") => jam "-sHDRS=/inc_root"

And then I can merrily compile the stuff - but it seems like jam can't to
locate the header; if I change anything in
"DISK$USER:[MYDIR.WHATEVER]WHOEVER.H" it doesn't result in a recompile of
whoever.cpp !

I also tried to include the VMS style directory specification in combination
with the unix-style stuff, e.g.:

jam "-sHDRS=/inc_root,DISK$USER:[MYDIR]"

Could somebody help me out here, please. Is there a way out or does anyone
have a patch available for jam?

Oh, and on a related question (i.e. jam+OpenVMS+cxx): When creating a
library (olb) using c++ templates, has anyone been able to insert the
template instantiations from the repository directory using jam? I tried the
following (which did not work) :

Library MyLib : file1.cpp file2.cpp ;
LibraryFromObjects MyLib : [ glob [.cxx_repository] : *.obj ] ;
