freebsd-ports

History

John Baldwin 66614bf3f5 Rename base/gcc to base/gcc6. This is in preparation for adding a base/gcc9 port. While here, update to GCC 6.5.0. Share packing lists with the freebsd-gcc6 port as much as posible. Split most of the freebsd-gcc6 pkg-plist into a pkg-plist.common that lists arch-independent files under lib/. Change base/gcc6 to use the arch-specific packing lists and pkg-list.common from freebsd-gcc6. In addition, hook up packing lists for the remaining archs supported by freebsd-gcc6 but not base/gcc6: aarch64 and sparc64.

How to cross build initial toolchain

Example with sparc64

1/ install a cross toolchain
pkg install sparc64-xtoolchain-gcc

2/ cross build world
make CROSS_TOOLCHAIN=sparc64-gcc TARGET=sparc64 TARGET_ARCH=sparc64 buildworld

3/ install the world in a sysroot
make CROSS_TOOLCHAIN=sparc64-gcc TARGET=sparc64 TARGET_ARCH=sparc64 installworld DESTDIR=/sysroots/sparc64

4/ build the required port
$ cd base/binutils
make CROSS_TOOLCHAIN=sparc64-gcc CROSS_SYSROOT=/sysroots/sparc64 package

$ cd base/gcc
make CROSS_TOOLCHAIN=sparc64-gcc CROSS_SYSROOT=/sysroots/sparc64 package

the package are in base/gcc/work/pkg/*.txz and base/binutils/work/pkg/*.txz

To add a plist for a new binutils target
$ cd base/binutils
make CROSS_TOOLCHAIN=sparc64-gcc CROSS_SYSROOT=/sysroots/sparc64 makeplist > pkg-plist

edit the pkg-plist and remove everything which base does not provide via the
elftoolchain
