I've installed it and am trying to figure out how to write the base .jam for the compiler (need to read how to use it from the command line 1st, I guess) then I'll add it to my regression collection.
I am looking at an installation on v1.3 and from the quick scan I have done it seems that it should be possible to adapt the MS VC++ toolset (both BBv1 and BBv2) since Open Watcom: [1] provides an environment setup file at [ow]/setvars.bat (whereas for MS it is [vc]/bin/vcvars.bat. [2] provides an implementation of cl.exe at [ow]/binnt/cl.exe -- it should be easy to adapt to open watcom.
As far as I can tell, this should be fairly trivial for BBv1. The question is: how do we deal with BBv2.
Looking at this in general, the Digital Mars compiler provides a CL adapter, so it should be possible to do:
using msvc : 7.0 : "c:/.../vc/bin/cl.exe" ; using ow : 1.3 : "c:/watcom/binnt/cl.exe" ; using dm : 8.4 : "c:/dm/bin/cl.exe" ;
where ow and dm are defined something like (pseudocode):
# ow.jam
import msvc ; # bring in the msvc toolset
msvc.adapter : ow : 6.0 ; # treat the ow toolset as a msvc-6.0 clone. # tell msvc where the environment configuration is relative to cl.exe msvc.setup : ow : "../setvars.bat" ;
# --end ow.jam
I don't know how easy this would be to implement. The alternative would be to duplicate the msvc.jam configuration and adapt it for OpenWatcom and DigitalMars compilers.
I think the right solution would work like this: # ow.jam toolset.inherit ow : msvc ; rule init ( version : command * ) { # # The following is needed for all toolsets anyway. # local condition = [ common.check-init-parameters cw : version $(version) ] ; # If version is specified, we try to search first in default paths, # and only then in PATH. command = [ common.get-invocation-command msvc : cl.exe : $(command) : [ default-paths $(version) ] : $(version) ] ; common.handle-options msvc : $(condition) : $(command) : $(options) ; # # The following is a msvc-specific logic for detecting setup script # if $(command) { command = [ common.get-absolute-tool-path $(command[-1]) ] ; } local root = $(command:D) ; setup = $(root)\\bin\\$(setup) ; # CONSIDER: What's the point of 'call'. Can we invoke the script directly? setup = "call \""$(setup)"\" > nul " ; if [ os.name ] = NT { setup = $(setup)" " ; } else { setup = "cmd /S /C "$(setup)" \"&&\" " ; } # prefix with setup, or quoted path if any local prefix = $(setup) ; flags ow.compile .CC $(condition) : $(prefix)$(compiler) ; flags ow.compile .RC $(condition) : $(prefix)$(resource-compiler) ; flags ow.link .LD $(condition) : $(prefix)$(linker) ; flags ow.archive .LD $(condition) : $(prefix)$(linker) ; } Now, the part of locate script is just a copy paste, so it would be reasonable to factor it out into some function in the msvc module, and just call it from ow.jam. - Volodya
