[dpdk-dev] Impossible to build external application if user build DPDK with "make config"

[Tom Barbette]

Hi all,

If the user follows the quick guide 
(http://core.dpdk.org/doc/quick-start/) DPDK will be compiled in the 
"build" folder.

However, external applications will always fail to build because 
RTE_SDK_BIN is strictly defined as $RTE_SDK/$RTE_TARGET, and 
mk/internal/rte.extvars.mk needs to find .config in $RTE_SDK_BIN.

Therefore please apply the patch at:
http://patchwork.dpdk.org/patch/9991/ that allows external apps to 
override $RTE_SDK_BIN.

Or (less preferable) modify the quick start guide to use something more 
standard that allows to build with external apps (eg use the menu or 
propose "make config T=x86_64-native-linuxapp-gcc 
O=x86_64-native-linuxapp-gcc" instead). It's much easier for external 
apps maintainer to refer to the DPDK tutorial for DPDK installation.

Thanks!

Tom
