Usage: crossdev [options] --target TARGET
Options:
--b, --binutils ver Specify version of binutils to use
--g, --gcc ver Specify version of gcc to use
--k, --kernel ver Specify version of kernel headers to use
--l, --libc ver Specify version of libc to use
Note: versions support depend atom syntaxes:
e.g. ">=2.20" "~4.6.1" "=2.13.1-r3"
-A, --abis abis Specify ABIs to build, first one is the default
--host-abi abi Specify the ABI of the compiler itself
--env env Specify env settings for all packages (see below)
--[bdgkl]env env Specify env settings for binutils/gdb/gcc/kernel/libc
Note: make sure to quote: 'VAR="some value"\nFOO="cow"'
-f, --force I don't need a seat belt!
-S, --stable Use latest stable versions as default
-C, --clean target Uninstall specified target
-P, --portage opts Options to pass to emerge (see emerge(1))
--with[out]-headers Build C library headers before C compiler?
--show-fail-log If the build fails, dump the failing log
Overlay Options:
-oS, --overlays list Space delimited list of overlays to search
[default: `portageq repositories_configuration`]
-oO, --ov-output path Overlay to write crossdev package links
[default: uses repo with name 'crossdev', or
'cross-${CTARGET}', or falls back to first
from --overlays list]
-ob, --ov-binutils path Overlay for binutils ebuilds [default: search]
-od, --ov-gdb path Overlay for gdb ebuilds [default: search]
-og, --ov-gcc path Overlay for gcc ebuilds [default: search]
-ok, --ov-kernel path Overlay for kernel ebuilds [default: search]
-ol, --ov-libc path Overlay for C library ebuilds [default: search]
-ox, --ov-extra path Overlay for extra packages [default: search]
Stage Options:
-s0, --stage0 Build just binutils
-s1, --stage1 Also build a bare C compiler (no C library/
C++/shared GCC libs/C++ exceptions/etc...)
-s2, --stage2 Also build kernel headers
-s3, --stage3 Also build the C library
-s4, --stage4 Also build a full compiler [default]
(shared libs GCC/various lang frontends/etc...)
External Tooling Options:
--show-target-cfg Display target settings that crossdev will use
--init-target Setup config/overlay/etc... files only
Extra Fun (must be run after above stages):
--ex-only Skip the stage steps above
--ex-gcc Build extra gcc targets (gcj/ada/etc...)
--ex-gdb Build a cross gdb
--ex-pkg pkg Build extra packages (may be used multiple times)
Target (-t) takes a tuple ARCH-VENDOR-OS-LIBC; see 'crossdev -t help'
