We do not support toolchains from + the ELDK of Denx, + for two reasons:

+ +
    + +
  • The ELDK does not contain a pure toolchain (i.e just the + compiler, binutils, the C and C++ libraries), but a toolchain + that comes with a very large set of pre-compiled libraries and + programs. Therefore, Buildroot cannot import the sysroot + of the toolchain, as it would contain hundreds of megabytes of + pre-compiled libraries that are normally built by + Buildroot.
    • + +
  • The ELDK toolchains have a completely non-standard custom + mechanism to handle multiple library variants. Instead of using + the standard GCC multilib mechanism, the ARM ELDK uses + different symbolic links to the compiler to differentiate + between library variants (for ARM soft-float and ARM VFP), and + the PowerPC ELDK compiler uses a CROSS_COMPILE + environment variable. This non-standard behaviour makes it + difficult to support ELDK in Buildroot.
