We have :

 * Some documentation, available in docs/manual/, and that you can
   generate using "make manual" ;

 * This mailing-list, which is the traditional way of providing support
   in the free software / open-source world ;

 * The #buildroot IRC channel on Freenode

What is "TC" ?

Which issue ?

When you change toolchain options, you need to do a full rebuild, i.e
'make clean' followed by 'make'. Buildroot does not try to be smart,
and therefore does not rebuild anything unless you tell him to do so.

Please post the Buildroot .config file that allows you to produce this
build error, and we will try to reproduce it.

Best regards,
