| # This package implements the support for external toolchains, i.e |
| # toolchains that are available pre-built, ready to use. Such toolchain |
| # may either be readily available on the Web (Linaro, Sourcery |
| # CodeBench, from processor vendors) or may be built with tools like |
| # Crosstool-NG or Buildroot itself. So far, we have tested this |
| # with: |
| # |
| # * Toolchains generated by Crosstool-NG |
| # * Toolchains generated by Buildroot |
| # * Toolchains provided by Linaro for the ARM and AArch64 |
| # architectures |
| # * Sourcery CodeBench toolchains (from Mentor Graphics) for the ARM, |
| # MIPS, PowerPC, x86, x86_64 and NIOS 2 architectures. For the MIPS |
| # toolchain, the -muclibc variant isn't supported yet, only the |
| # default glibc-based variant is. |
| # * Analog Devices toolchains for the Blackfin architecture |
| # * Xilinx toolchains for the Microblaze architecture |
| # * Synopsys DesignWare toolchains for ARC cores |
| # |
| # The basic principle is the following |
| # |
| # 1. If the toolchain is not pre-installed, download and extract it |
| # in $(TOOLCHAIN_EXTERNAL_INSTALL_DIR). Otherwise, |
| # $(TOOLCHAIN_EXTERNAL_INSTALL_DIR) points to were the toolchain has |
| # already been installed by the user. |
| # |
| # 2. For all external toolchains, perform some checks on the |
| # conformity between the toolchain configuration described in the |
| # Buildroot menuconfig system, and the real configuration of the |
| # external toolchain. This is for example important to make sure that |
| # the Buildroot configuration system knows whether the toolchain |
| # supports RPC, IPv6, locales, large files, etc. Unfortunately, these |
| # things cannot be detected automatically, since the value of these |
| # options (such as BR2_TOOLCHAIN_HAS_NATIVE_RPC) are needed at |
| # configuration time because these options are used as dependencies |
| # for other options. And at configuration time, we are not able to |
| # retrieve the external toolchain configuration. |
| # |
| # 3. Copy the libraries needed at runtime to the target directory, |
| # $(TARGET_DIR). Obviously, things such as the C library, the dynamic |
| # loader and a few other utility libraries are needed if dynamic |
| # applications are to be executed on the target system. |
| # |
| # 4. Copy the libraries and headers to the staging directory. This |
| # will allow all further calls to gcc to be made using --sysroot |
| # $(STAGING_DIR), which greatly simplifies the compilation of the |
| # packages when using external toolchains. So in the end, only the |
| # cross-compiler binaries remains external, all libraries and headers |
| # are imported into the Buildroot tree. |
| # |
| # 5. Build a toolchain wrapper which executes the external toolchain |
| # with a number of arguments (sysroot/march/mtune/..) hardcoded, |
| # so we're sure the correct configuration is always used and the |
| # toolchain behaves similar to an internal toolchain. |
| # This toolchain wrapper and symlinks are installed into |
| # $(HOST_DIR)/usr/bin like for the internal toolchains, and the rest |
| # of Buildroot is handled identical for the 2 toolchain types. |

| # Details about sysroot directory selection. |
| # |
| # To find the sysroot directory, we use the trick of looking for the |
| # 'libc.a' file with the -print-file-name gcc option, and then |
| # mangling the path to find the base directory of the sysroot. |
| # |
| # Note that we do not use the -print-sysroot option, because it is |
| # only available since gcc 4.4.x, and we only recently dropped support |
| # for 4.2.x and 4.3.x. |
| # |
| # When doing this, we don't pass any option to gcc that could select a |
| # multilib variant (such as -march) as we want the "main" sysroot, |
| # which contains all variants of the C library in the case of multilib |
| # toolchains. We use the TARGET_CC_NO_SYSROOT variable, which is the |
| # path of the cross-compiler, without the --sysroot=$(STAGING_DIR), |
| # since what we want to find is the location of the original toolchain |
| # sysroot. This "main" sysroot directory is stored in SYSROOT_DIR. |
| # |
| # Then, multilib toolchains are a little bit more complicated, since |
| # they in fact have multiple sysroots, one for each variant supported |
| # by the toolchain. So we need to find the particular sysroot we're |
| # interested in. |
| # |
| # To do so, we ask the compiler where its sysroot is by passing all |
| # flags (including -march and al.), except the --sysroot flag since we |
| # want to the compiler to tell us where its original sysroot |
| # is. ARCH_SUBDIR will contain the subdirectory, in the main |
| # SYSROOT_DIR, that corresponds to the selected architecture |
| # variant. ARCH_SYSROOT_DIR will contain the full path to this |
| # location. |
| # |
| # One might wonder why we don't just bother with ARCH_SYSROOT_DIR. The |
| # fact is that in multilib toolchains, the header files are often only |
| # present in the main sysroot, and only the libraries are available in |
| # each variant-specific sysroot directory. |

| # |
| # SYSROOT_DIR: the main sysroot directory, deduced from |
| # LIBC_A_LOCATION by removing the |
| # usr/lib[32|64]/libc.a part of the path. |
| # Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/ |
| # |
| # ARCH_LIBC_A_LOCATION: location of the libc.a file in the selected |
| # multilib variant (taking into account the |
| # CFLAGS). Allows to find the sysroot of the |
| # selected multilib variant. |
| # Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/mips16/soft-float/el/usr/lib/libc.a |
| # |
| # ARCH_SYSROOT_DIR: the sysroot of the selected multilib variant, |
| # deduced from ARCH_LIBC_A_LOCATION by removing |
| # usr/lib[32|64]/libc.a at the end of the path. |
| # Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/mips16/soft-float/el/ |
| # |
| # ARCH_LIB_DIR: 'lib', 'lib32' or 'lib64' depending on where libraries |
| # are stored. Deduced from ARCH_LIBC_A_LOCATION by |
| # looking at usr/lib??/libc.a. |
| # Ex: lib |
| # |
| # ARCH_SUBDIR: the relative location of the sysroot of the selected |
| # multilib variant compared to the main sysroot. |
| # Ex: mips16/soft-float/el |
| # |
| # SUPPORT_LIB_DIR: some toolchains, such as recent Linaro toolchains, |
| # store GCC support libraries (libstdc++, |
| # libgcc_s, etc.) outside of the sysroot. In |
| # this case, SUPPORT_LIB_DIR is set to a |
| # non-empty value, and points to the directory |
| # where these support libraries are |
