Dear Boost experts,
since a while I am trying to compile Boost from the source in a 32b linux machine with c++11 enabled. The compiler version used is gcc4.8.1
This is performed through cmake as follows:
--> Configuration: bootstrap.sh --with-python= --with-toolset=gcc
--> Build: /b2 -j4 variant=release --layout=versioned --debug-configuration --toolset=gcc --user-config=<path to a user-config.jam>
Where user-config.jam contains the following information:
using gcc : : : <linkflags>-m32 <compileflags>-m32 -std=gnu++0x
also tested it with -std=c++11
And finally installed which basically contains the same options as the build adding --prefix=<installation dir>
The libraries built following this procedure does not seem to have been created with c++11. If I compare the signatures of the same library build in 64 against 32 the result are
In 64:
nm --defined-only --demangle libboost_filesystem-gcc48-mt-1_55.so | grep copy_file
boost::filesystem::detail::copy_file(boost::filesystem::path const&,
boost::filesystem::path const&, boost::filesystem::copy_option, boost::system::error_code*)
In 32, the same produces:
boost::filesystem::detail::copy_file(boost::filesystem::path
const&, boost::filesystem::path const&, boost::filesystem::copy_option::enum_type, boost::system::error_code*)
The difference seems to come from wrong i686 build options. Could you please help me to find the good options to build these libs in 32b with c+=11 enabled?
Thank you so much,
