Hello Everyone,

I have spent some time trying to build BOOST libraries from source code on Ubuntu machine.
BOOST version is boost_1_73_0.
I use ARM compiler

echo $CC
arm-oe-linux-gnueabi-gcc -march=armv7-a -mfloat-abi=hard -mfpu=neon --sysroot=/home/lm/rfnoc/oe/sysroots/armv7ahf-vfp-neon-oe-linux-gnueabi

My current directory is boost_1_73_0

1.       I have edited user-config.jam file, adding

gcc_root = $(CC) ;

using gcc : arm : $(gcc_root)

This file is located on 'parent' BOOST directory - boost_1_73_0.

2.       Run
lm_at_ubuntu:~/boost/boost_1_73_0$ ./bootstrap.sh --prefix=bbb
Building Boost.Build engine with toolset gcc... tools/build/src/engine/b2
Detecting Python version... 2.7
Detecting Python root... /home/lm/rfnoc/oe/sysroots/x86_64-oesdk-linux/usr
Unicode/ICU support for Boost.Regex?... /usr
Backing up existing Boost.Build configuration in project-config.jam.4
Generating Boost.Build configuration in project-config.jam for gcc...

Bootstrapping is done. To build, run:

    ./b2

To generate header files, run:

    ./b2 headers

To adjust configuration, edit 'project-config.jam'.
Further information:

   - Command line help:
     ./b2 --help

   - Getting started guide:
     http://www.boost.org/more/getting_started/unix-variants.html

   - Boost.Build documentation:
     http://www.boost.org/build/

3.       So far it looks OK, I run b2 and have got an error

lm_at_ubuntu:~ /boost/boost_1_73_0$ b2

Could somebody explain what this error means and what I am doing wrong?

Thank you,
Leonid
