It is implemented at http://git.buildroot.net/buildroot/tree/toolchain/helpers.mk#n246. And yes, it does both the "positive" check and the "negative" check: * If the toolchain has thread support, but the user hasn't selected the thread support for his external toolchain, we error out. * If the toolchain does not have thread support, but the user has selected thread support, we error out. > > > As to MMU, for some reason this is option is disabled on your > > > configuration, although clearly your target has MMU enabled. > > > > Where have you seen Gabi's .config ?

Ok. We clearly don't have enough informations to help Gabi, unfortunately. Thomas -- Thomas Petazzoni, CTO, Free Electrons Embedded Linux, Kernel and Android engineering http://free-electrons.com
