Hi, Our toolchain generates files ending in ".doj" for objects, so I've been trying to configure my custom toolset module to use this. My original module is based on acc.jam but qcc.jam had something that looked like it would do the trick, so I lifted that and chucked into my module: import type ; type.set-generated-target-suffix OBJ : <toolset>bfin : doj ; type.set-generated-target-suffix STATIC_LIB : <toolset>bfin : dlb ; However my build of Boost now fails, with a fairly long error tracing: smclemo@edin-angus /usr/src/boost_1_39_0 $ bjam toolset=bfin WARNING: No python installation configured and autoconfiguration failed. See http://www.boost.org/libs/python/doc/building.html for configuration instructions or pass --without-python to suppress this message and silently skip all Boost.Python targets Building C++ Boost. After the build, the headers will be located at C:\cygwin\usr\src\boost_1_39_0 The libraries will be located at C:\cygwin\usr\src\boost_1_39_0\stage\lib Use 'bjam install --prefix=<path>' if you wish to install headers and libraries to a different location and remove the source tree.

Is anyone in the position to confirm this, or do I need to send the module around? Also is it OK that I'm posting this here, or is there a more appropriate mailing list I should be using? - Sean
