I'm trying to cross compile boost for armhf but some of the functions seem to be missed.
I'm using croos-tool ng, gcc-4.8
=================================
For example in file system, boost::filesystem::detail::status is not there:
nm stage/lib/linux_armv7/libboost_filesystem.a | grep status
[returns nothing]
=================================
I take a look on an existing ubuntu.14.04 armhf
nm libboost_filesystem.a | grep status
00000048 t _ZN12_GLOBAL__N_113dir_itr_firstERPvS1_PKcRSsRN5boost10filesystem11file_statusES8_.isra.29.constprop.49
00001cf4 T _ZN5boost10filesystem6detail14symlink_statusERKNS0_4pathEPNS_6system10error_codeE

I use this patch to fix the zlib problem in boost_1.55
