Hi guys I posted this in boost-users but not much attention there.

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
000019c0 T _ZN5boost10filesystem6detail6statusERKNS0_4pathEPNS_6system10error_codeE
00001b54 T _ZNK5boost10filesystem15directory_entry12m_get_statusEPNS_6system10error_codeE
00001e98 T _ZNK5boost10filesystem15directory_entry20m_get_symlink_statusEPNS_6system10error_codeE
=================================

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