These toolchains shall provide the capability to compile executables in 64 = bits (aarch64) and 32 bits (armv7a architecture). For X86, this seems very simple : In the local.conf, adding this is enough = : require conf/multilib.conf MULTILIBS =3D "multilib:lib32" DEFAULTTUNE_virtclass-multilib-lib32 =3D "i586" But for ARM (LS1046 from NXP), it is not as evident : in the local.conf, we= add : require conf/multilib.conf MULTILIBS =3D "multilib:lib32" DEFAULTTUNE_virtclass-multilib-lib32 =3D "armv7a" This correctly add 32 bits libraries both in the image and in the SDK. But the SDK only provides the gcc for 64 bits, not for 32 bits. Only 64 bits environment file is provided. Does someone have some experience on this?
