gcc via $PATH is the system gcc (version 4.3 or something I think); the gcc
boost / b2 uses is the gcc in user_config.jam (this can be seen not from
the bootstrap.log output; but from the output of b2) - I'm using 4.7.2

It eventually defaults to cc toolset and it takes the

Below is the log, I'm using 1.51

---------------------

So I ripped out the relevant details from my scripts and ran them from the
command line. The following, if I literally just copy-paste it to my linux
command line, works. If it doesn't for you, then perhaps there is something
wrong with your environment?

Note you will obviously have to change the first few lines to specify your
$PREFIX and your GCC 4.7.2 location
Note also it relies on boost_1_51_0.tar.gz being in the current directory.

---------------------

# this section you will have to change to correctly specify your $PREFIX
and your compiler version/location
export PREFIX=/hostname/trading/sdk/
export GLIBC_VER=`/lib/libc.so.6 | head -n1 | cut -f7 -d' '`
export MACHINE_ARCH=`/bin/arch`
export KERNEL_NAME=`uname -s | tr A-Z a-z`
export GCCVER=gcc-4.7.2
export COMPDIR=${PREFIX}/${MACHINE_ARCH}/${GLIBC_VER}/${GCCVER}/bin

# store current dir as the external build root dir
export BUILD_DIR=`pwd`
pushd $BUILD_DIR > /dev/null

# override compiler env vars
export AR="$COMPDIR/ar"
export CC="$COMPDIR/gcc"
export CPP="$COMPDIR/gcc -E"
export CXX="$COMPDIR/g++"
export CXXCPP="$COMPDIR/g++ -E"

# boost version and where to get it
export BOOST_VER=1.51.0

# this is for default and pic builds - here I show only the default (which
will be for statically linked libs)
 export TARGET_BUILD_CONF=Def

# create subdirectory for specific build configuration
mkdir -p ${GCCVER}_${TARGET_BUILD_CONF}
pushd ${GCCVER}_${TARGET_BUILD_CONF} > /dev/null

# unpack source code
tar -xf ../boost_${BOOST_DL_VERSION}.tar.gz

pushd boost_${BOOST_DL_VERSION}

# add your custom compiler to the end of the boost jam config file
cat <<EOF > ./tools/build/v2/user-config.jam
using gcc : : $COMPDIR/g++ ;
EOF

# bootstrap the build
./bootstrap.sh --prefix=${PREFIX} --with-libraries=filesystem,regex,system

# build it
./b2 --toolset=gcc

---------------------

The output from pasting the above to the command line is as follows:

---------------------

$ ls -1 boost_1_51_0.tar.gz
boost_1_51_0.tar.gz
