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

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