   3 # This file implements the support for external toolchains, i.e
   4 # toolchains that have not been produced by Buildroot itself and that
   5 # Buildroot can download from the Web or that are already available on
   6 # the system on which Buildroot runs. So far, we have tested this
   7 # with:
   8 #
   9 #  * Toolchains generated by Crosstool-NG
  10 #  * Toolchains generated by Buildroot
  11 #  * ARM, MIPS and PowerPC toolchains made available by
  12 #    Codesourcery. For the MIPS toolchain, the -muclibc variant isn't
  13 #    supported yet, only the default glibc-based variant is.
  14 #
  15 # The basic principle is the following
  16 #
  17 #  1. If the toolchain is not pre-installed, download and extract it
  18 #  in $(TOOLCHAIN_EXTERNAL_DIR).
  19 #
  20 #  2. For all external toolchains, perform some checks on the
  21 #  conformity between the toolchain configuration described in the
  22 #  Buildroot menuconfig system, and the real configuration of the
  23 #  external toolchain. This is for example important to make sure that
  24 #  the Buildroot configuration system knows whether the toolchain
  25 #  supports RPC, IPv6, locales, large files, etc. Unfortunately, these
  26 #  things cannot be detected automatically, since the value of these
  27 #  options (such as BR2_TOOLCHAIN_HAS_NATIVE_RPC) are needed at
  28 #  configuration time because these options are used as dependencies
  29 #  for other options. And at configuration time, we are not able to
  30 #  retrieve the external toolchain configuration.
  31 #
  32 #  3. Copy the libraries needed at runtime to the target directory,
  33 #  $(TARGET_DIR). Obviously, things such as the C library, the dynamic
  34 #  loader and a few other utility libraries are needed if dynamic
  35 #  applications are to be executed on the target system.
  36 #
  37 #  4. Copy the libraries and headers to the staging directory. This
  38 #  will allow all further calls to gcc to be made using --sysroot
  39 #  $(STAGING_DIR), which greatly simplifies the compilation of the
  40 #  packages when using external toolchains. So in the end, only the
  41 #  cross-compiler binaries remains external, all libraries and headers
  42 #  are imported into the Buildroot tree.
  43 #
  44 #  5. Build a toolchain wrapper which executes the external toolchain
  45 #  with a number of arguments (sysroot/march/mtune/..) hardcoded,
  46 #  so we're sure the correct configuration is always used and the
  47 #  toolchain behaves similar to an internal toolchain.
  48 #  This toolchain wrapper and symlinks are installed into
  49 #  $(HOST_DIR)/usr/bin like for the internal toolchains, and the rest
  50 #  of Buildroot is handled identical for the 2 toolchain types.

  69 # Details about sysroot directory selection.
  70 #
  71 # To find the sysroot directory:
  72 #
  73 #  * We first try the -print-sysroot option, available in gcc 4.4.x
  74 #    and in some Codesourcery toolchains.
  75 #
  76 #  * If this option is not available, we fallback to the value of
  77 #    --with-sysroot as visible in CROSS-gcc -v.
  78 #
  79 # When doing those tests, we don't pass any option to gcc that could
  80 # select a multilib variant (such as -march) as we want the "main"
  81 # sysroot, which contains all variants of the C library in the case of
  82 # multilib toolchains. We use the TARGET_CC_NO_SYSROOT variable, which
  83 # is the path of the cross-compiler, without the
  84 # --sysroot=$(STAGING_DIR), since what we want to find is the location
  85 # of the original toolchain sysroot. This "main" sysroot directory is
  86 # stored in SYSROOT_DIR.
  87 #
  88 # Then, multilib toolchains are a little bit more complicated, since
  89 # they in fact have multiple sysroots, one for each variant supported
  90 # by the toolchain. So we need to find the particular sysroot we're
  91 # interested in.
  92 #
  93 # To do so, we ask the compiler where its sysroot is by passing all
  94 # flags (including -march and al.), except the --sysroot flag since we
  95 # want to the compiler to tell us where its original sysroot
  96 # is. ARCH_SUBDIR will contain the subdirectory, in the main
  97 # SYSROOT_DIR, that corresponds to the selected architecture
  98 # variant. ARCH_SYSROOT_DIR will contain the full path to this
  99 # location.
 100 #
 101 # One might wonder why we don't just bother with ARCH_SYSROOT_DIR. The
 102 # fact is that in multilib toolchains, the header files are often only
 103 # present in the main sysroot, and only the libraries are available in
 104 # each variant-specific sysroot directory.

 389 # Integration of the toolchain into Buildroot: find the main sysroot
 390 # and the variant-specific sysroot, then copy the needed libraries to
 391 # the $(TARGET_DIR) and copy the whole sysroot (libraries and headers)
 392 # to $(STAGING_DIR).
 393 #
 394 # Variables are defined as follows:
 395 #
 396 #  LIBC_A_LOCATION:     location of the libc.a file in the default
 397 #                       multilib variant (allows to find the main
 398 #                       sysroot directory)
 399 #                       Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/usr/lib/libc.a
 400 #
 401 #  SYSROOT_DIR:         the main sysroot directory, deduced from
 402 #                       LIBC_A_LOCATION by removing the
 403 #                       usr/lib[32|64]/libc.a part of the path.
 404 #                       Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/
 405 #
 406 # ARCH_LIBC_A_LOCATION: location of the libc.a file in the selected
 407 #                       multilib variant (taking into account the
 408 #                       CFLAGS). Allows to find the sysroot of the
 409 #                       selected multilib variant.
 410 #                       Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/mips16/soft-float/el/usr/lib/libc.a
 411 #
 412 # ARCH_SYSROOT_DIR:     the sysroot of the selected multilib variant,
 413 #                       deduced from ARCH_LIBC_A_LOCATION by removing
 414 #                       usr/lib[32|64]/libc.a at the end of the path.
 415 #                       Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/mips16/soft-float/el/
 416 #
 417 # ARCH_LIB_DIR:         'lib', 'lib32' or 'lib64' depending on where libraries
 418 #                       are stored. Deduced from ARCH_LIBC_A_LOCATION by
 419 #                       looking at usr/lib??/libc.a.
 420 #                       Ex: lib
 421 #
 422 # ARCH_SUBDIR:          the relative location of the sysroot of the selected
 423 #                       multilib variant compared to the main sysroot.
 424 #                       Ex: mips16/soft-float/el
 425 #
 426 # SUPPORT_LIB_DIR:      some toolchains, such as recent Linaro toolchains,
 427 #                       store GCC support libraries (libstdc++,
 428 #                       libgcc_s, etc.) outside of the sysroot. In
 429 #                       this case, SUPPORT_LIB_DIR is set to a
 430 #                       non-empty value, and points to the directory
 431 #                       where these support libraries are
 432 #                       available. Those libraries will be copied to
 433 #                       our sysroot, and the directory will also be
 434 #                       considered when searching libraries for copy
 435 #                       to the target filesystem.
