Hello Thomas,
Will check the below.
>> Have you enable largefile support in your configuration?
I am using "buildroot-2013.02", the below was copied from another post that I found the same topic.
>> BR2_GCC_CROSS_CXX option has been removed in december 2010. I would
_really_ recommend you to upgrade to a more recent Buildroot version.
regards,
Prabindh

Have you enable largefile support in your configuration?

The first one is useless, because it enables C++ on the native compiler
on the target (which is a deprecated feature anyway). And also, this
BR2_GCC_CROSS_CXX option has been removed in december 2010. I would
_really_ recommend you to upgrade to a more recent Buildroot version.
We're clearly not going to support a Buildroot version that's 2 years
old, considering how many things have changed since then.
BR2_INSTALL_LIBSTDCPP (despite its bizarre name) is the right option to
have C++ support in the cross-compiler.
