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 : $(gcc_root) This file is located on 'parent' BOOST directory - boost_1_73_0. 2. Run lm@ubuntu:~/boost/boost_1_73_0$ ./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@ubuntu:~ /boost/boost_1_73_0$ b2 /home/lm/covra-liquidsdr/boost/boost_1_73_0/tools/build/src/tools/features/warnings-feature.jam:27: in load ERROR: rule "[[bbv2.builtin.features.warnings]]`warnings`::" unknown in module "warnings-feature". /home/lm/covra-liquidsdr/boost/boost_1_73_0/tools/build/src/kernel/modules.jam:295: in import /home/lm/covra-liquidsdr/boost/boost_1_73_0/tools/build/src/tools/features/__init_features__.jam:22: in load /home/lm/covra-liquidsdr/boost/boost_1_73_0/tools/build/src/kernel/modules.jam:295: in import /home/lm/covra-liquidsdr/boost/boost_1_73_0/tools/build/src/tools/builtin.jam:16: in load /home/lm/covra-liquidsdr/boost/boost_1_73_0/tools/build/src/kernel/modules.jam:295: in import /home/lm/covra-liquidsdr/boost/boost_1_73_0/tools/build/src/build-system.jam:12: in load /home/lm/covra-liquidsdr/boost/boost_1_73_0/tools/build/src/kernel/modules.jam:295: in import /home/lm/covra-liquidsdr/boost/boost_1_73_0/tools/build/src/kernel/bootstrap.jam:139: in boost-build /home/lm/covra-liquidsdr/boost/boost_1_73_0/boost-build.jam:17: in module scope Could somebody explain what this error means and what I am doing wrong?
