Hi all,
I was confused with cross compiling, when I built vpp with the new
version(18.10) using arm build tools.
The compiling environment is listed below:
-----------------------------------------------------------------
vpp 18.10
host : ubuntu 16.04 , x86-64 cpu
target : armv71
toolchain : arm-linux-gcc alredy exist in my home directory
------------------------------------------------------------------
The compiling process is listed below:
--------------------------------------------------------------------------------------------------
user@vpp-compiler:~/vpp1810$ make build V=1 PLATFORM=arm32 or
~/vpp1810/build-root$ make V=1 PLATFORM=arm32 TAG=vpp install-deb
