Re: [Boost-build] Simple bjam question: linking in boost libraries?

It's helping, and I'm very close!

The new Jamfile.v2:
using gcc ;

exe mfront :
        driver/config.cpp
        driver/driver.cpp
        driver/output.cpp
        main.cpp
        map/map.cpp
        parser/actions.cpp
        parser/generator.cpp
        $(BOOST_ROOT)//filesystem
        $(BOOST_ROOT)//wave
        $(BOOST_ROOT)//regex
        : <include>. <include>/usr/local/src/boost
        ;

Only thing that fails now is an unknown flag given to ld:
gcc.link bin/gcc/debug/mfront
/usr/bin/ld: unknown flag: --start-group
collect2: ld returned 1 exit status

    "g++"    -o "bin/gcc/debug/mfront" -Wl,--start-group
"bin/gcc/debug/config.o" "bin/gcc/debug/driver.o"
"bin/gcc/debug/output.o" "bin/gcc/debug/main.o" "bin/gcc/debug/map.o"
"bin/gcc/debug/actions.o" "bin/gcc/debug/generator.o"
-Wl,--end-group -g

...failed gcc.link bin/gcc/debug/mfront...
...failed updating 1 target...
...updated 7 targets...

Perhaps I need to define a different toolchain? (MacOSX 10.4.6)

Also, one slightly-related question: is there a way to call the
compiler with another name (e.g. call "gfilt" instead of "g++")?  I'd
like to use STLFilt.

Thanks for your help!
