[Boost-users] [Boost.Build v2] problem with multiple version build

From: Dick Bridges (dbridges_at_[hidden])

I can't seem to get bjam v2 to build multiple library versions.

The O/S is:
# uname -a
Linux myhost 2.6.9-1.667 #1 Tue Nov 2 14:41:25 EST 2004 i686 i686 i386
GNU/Linux

First I untarD boost_1_33_1.tar.bz2 to /home/dick and followed the
instructions for building bjam.  Then I copied bjam to /home/dick/bin.

Next I modified
/home/dick/boost_1_33_1/tools/build/v2/example/hello/user-config.jam
adding the 3.4.4.x86 and 3.3.arm versions like so:

<mod>
#  Configure specific gcc version, giving alternative name to use
#  using gcc : 3.2 : g++-3.2 ;

   using gcc : 3.4.4.x86 ;

   using gcc : 3.3.arm : <fake CR>
      /opt/crosstool/arm-softfloat-linux-gnu/<fake CR>
      gcc-3.3.3-glibc-2.3.2<fake CR>
      /bin/arm-softfloat-linux-gnu-c++ ;

</mod>

Then (because I'm confused) I copied the modified user-config.jam to
/home/dick/boost_1_33_1 as well.

The version seems to be correct.
cd /home/dick/boost_1_33_1
# ~/bin/bjam --v2 --version
Boost.Build V2 (Milestone 10)
Boost.Jam 03.01.11

The example/hello build seems to work.
cd /home/dick/boost_1_33_1/tools/build/v2/example/hello
# ~/bin/bjam gcc-3.4.4.x86 gcc-3.3.arm

...found 13 targets...
...updating 9 targets...
MkDir1 bin
MkDir1 bin/gcc-3.4.4.x86
MkDir1 bin/gcc-3.4.4.x86/debug
gcc.compile.c++ bin/gcc-3.4.4.x86/debug/hello.o
gcc.link bin/gcc-3.4.4.x86/debug/hello
MkDir1 bin/gcc-3.3.arm
MkDir1 bin/gcc-3.3.arm/debug
gcc.compile.c++ bin/gcc-3.3.arm/debug/hello.o
gcc.link bin/gcc-3.3.arm/debug/hello
...updated 9 targets...

Now I hit a brick wall.  I've tried setting both
BOOST_BUILD_PATH and BOOST_ROOT to both
/home/dick/boost_1_33_1/tools/build/v2 and
/home/dick/boost_1_33_1.

If I try

cd /home/dick/boost_1_33_1
# ~/bin/bjam gcc-3.4.4.x86 gcc-3.3.arm install

I get
<msg>
don't know how to make gcc-3.4.4.x86
don't know how to make gcc-3.3.arm
</msg>

If I try
cd /home/dick/boost_1_33_1/tools/build/v2
# ~/bin/bjam gcc-3.4.4.x86 gcc-3.3.arm install

I get <msg>

Apologies for all the error messages but I'm so lost I don't even know
what can be snipped and what is meaningful.  I'd be very
grateful if someone could point me in the right direction.
