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.
