(future) #-------------------------------------------------------------------------------- # Tips for build() #-------------------------------------------------------------------------------- # * If builing without "--disable-multilib" make sure to have "--with-python-dir=share/gcc-$_target" # # * When building using `make' instead of `make all-gcc' append "--with-sysroot=/usr/$_target" and # "--with-native-system-header-dir=/include". You'll also have to build and add a libc implementation # in makedepends as $_target- (e.g. $_target-newlib or $_target-glibc) #-------------------------------------------------------------------------------- # Choosing the correct pkgdesc #-------------------------------------------------------------------------------- # You must know wether your toolchain is a bare-metal one, if it's specifically for big-endian or # little-endian order and know its full name, if possible. Here are some useful tips: # # * If the toolchain has no operating system (see the toolchain triplet, <_os_target>), then it's a # bare-metal toolchain, in which case you have to specify it in the pkgdesc # # * Do a bit of research in forums, wikis and documents about the target you plan to build, a good # idea is to see the description that other distros put (e.g. Debian) if they have the same toolchain # # Example: arm-linux-gnueabi-{gcc,binutils,$etc} # This toolchain has GNU/Linux as OS, so it's not a bare-metal one. It's for armel, which # stands for "ARM EABI little-endian", but the gnueabi part means it uses the GNU EABI. You can find # that info in Debian's gcc-arm-linux-gnueabi and a couple of FLOSS and programmers community forums. # Toolchain triplet: <_arch>--<_os_target> # is generally optional and uneeded _target=x86_64-pc-linux-gnu # This are some common options for names.
