ArmSuite

Several times, I had to recompile the entire GCC for ARM suite (including the link tools, the debugger, the C library and the GCC core). I have always used the script provided here and I updated the problems encountered at the beginning of the script.

The script was tested with the following tarballs:

  1. mid-2009: * binutils-2.19.1.tar.gz * gdb-6.8.50.20090912.tar.bz2 (the 6.8 stable release does not support the ARM-THUMB automatic disassembly) * gmp-4.2.4.tar.bz2 * mpfr-2.4.1.tar.bz2 * gcc-core-4.4.0.tar.bz2 * newlib-1.17.0.tar.gz
  2. beginning-2010: * binutils-2.20.51.tar.bz2 * gdb-7.1.tar.bz2 (the 6.8 stable release does not support the ARM-THUMB automatic disassembly) * gmp-4.3.2.tar.bz2 * mpfr-2.4.2.tar.bz2 * gcc-core-4.4.3.tar.bz2 * newlib-1.18.0.tar.gz
  3. beginning-2014: chose not to recompile the dependency libraries but get them from system install (as advised on http://gcc.gnu.org/wiki/InstallingGCC) and compiled arm-none-eabi rather than arm-elf * binutils-2.24 * gdb-7.7 * gcc-4.8.2 * newlib-2.1.0

The script to recompile everything including the dependency libraries is the following:

#! /bin/sh

# Problems encountered:
# 1. during binutils/configure:
#    - gcc can not build executables (ld can not find ctr0.o) -> reinstall the Cygwin base package
# 2. during binutils compilation:
#    - libtool: link: cannot find the library `/usr/lib/libiconv.la' or unhandled argument `/usr/lib/libiconv.la' -> install Cygwin libicvon package
# 3. during gdb compilation:
#    -  WARNING: no enhanced curses library found; disabling TUI -> not necessary if I dont use TUI
#    - configure: error: no termcap library found -> install Cygwin libncurses-devel
# 4. during gmp compilation:
#    - checking for suitable m4... configure: error: No usable m4 in $PATH or /usr/5bin (see config.log for reasons). -> install Cygwin m4 (Interpreters)
# 5. during the gcc rest compilation and install, I faced the following issue:
#checking for suffix of object files... configure: error: in '.../libgcc':
#configure: error: cannot compute suffix of object files: cannot compile
#See `config.log' for more details.
#  this problem was hit because I had compiled binutils while the $prefix variable had not been updated
# to the latest gcc  version so recompiling everything fixed the issue, but the error message is
# very confusing and came much later than the gcc successful compilation (and even the newlib)

# - libmpc-devel
# - libmprf-devel
# - libncurses-devel
