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
|
