Build arm GCC tool chain (update)

The main difference between this article and the previous one is that there is no use of system GMP, MPFR, MPC, Cloog, etc., but using source code to compile.

1. Compile binutils:

Unzip the BINUTLS code into the SRC directory and create the Binutil directory in the build directory.

Execute in the Build/binutils directory:

.. /.. /src/binutils-2.25/configure--prefix=/home/charles/code/build_toolchain/toolchain--with-sysroot=/home/charles/ Code/build_toolchain/toolchain/arm-linux-gnueabi/sysroot--target=arm-linux-gnueabi

Make-j10-i-K Make
Install

2. Install kernel header file

Unzip the kernel code into the SRC directory, then go to the kernel code directory and execute:

Make Mrproper make  
arch=arm vexpress_defconfig make arch=arm headers_check make Arch=arm  
Install_hdr_path =/home/charles/code/build_toolchain/toolchain/arm-linux-gnueabi/sysroot/usr Headers_install Find
. /.. /toolchain/arm-linux-gnueabi/sysroot/usr/include/-name ". Install"-or-name ". Install.cmd "| Xargs RM-FV  

We also need to add the location of this library to the Ld_library_path.

3. Enter the directory sequentially:

gmp-6.0.0 mpc-1.0.2 mpfr-3.1.2 ppl-1.1 cloog-0.18.1

Perform:

./configure--prefix=/home/charles/code/build_toolchain/toolchain make make 
install

4. Create Bootstrap GCC

Create directory Build/gcc_first and enter into this directory to execute:

.. /.. /src/gcc-4.8.2/configure--build=i686-pc-linux-gnu  --target=arm-linux-gnueabi--prefix=/home/charles/code/ Build_toolchain/toolchain--with-sysroot=/home/charles/code/build_toolchain/toolchain/arm-linux-gnueabi/sysroot  --with-newlib--without-headers--disable-threads  --enable-__cxa_atexit--disable-libmudflap-- Disable-libgomp--DISABLE-LIBSSP--disable-nls  --disable-shared  --disable-decimal-float  -- With-gnu-ld  --with-gnu-as--with-arch=armv7-a--with-mode=arm  --with-float=softfp--with-fpu=vfpv3  -- Enable-languages=c   --with-gmp=/home/charles/code/build_toolchain/toolchain--with-mpfr=/home/charles/code/ Build_toolchain/toolchain--with-ppl=/home/charles/code/build_toolchain/toolchain--with-cloog=/home/charles/ Code/build_toolchain/toolchain

Make All-gcc-j10-i-K make
INSTALL-GCC make
all-target-libgcc make
INSTALL-TARGET-LIBGCC

5. Compile GLIBC

First Execute:

Export path= $PATH:/home/charles/code/build_toolchain/toolchain/bin

Create directory BUILD/GLIBC, enter this directory, execute:

CC=ARM-LINUX-GNUEABI-GCC Ar=arm-linux-gnueabi-ar  ranlib=arm-linux-gnueabi-ranlib. /.. /src/glibc-2.21/configure   --build=i686-pc-linux-gnu  --host=arm-linux-gnueabi--prefix=/usr  -- With-headers=/home/charles/code/build_toolchain/toolchain/arm-linux-gnueabi/sysroot/usr/include  -- Enable-add-ons--with-mode=arm

If you report an error similar to the following:

No rule to make target '/root/glibc-2.14-build/dlfcn/libdl.so.2 '

Execute make all first, and then

6. Compile the final gcc:

Create directory Build/gcc_final, execute:

.. /.. /src/gcc-4.8.2/configure--build=i686-pc-linux-gnu--target=arm-linux-gnueabi--prefix=/home/charles/code/build_ Toolchain/toolchain--with-sysroot=/home/charles/code/build_toolchain/toolchain/arm-linux-gnueabi/sysroot-- Disable-libmudflap--DISABLE-LIBSSP--disable-nls--disable-libstdcxx-pch--with-interwork--with-mode=arm-- With-fpu=vfpv3--with-arch=armv7-a--WITH-FLOAT=SOFTFP--enable-libgomp--enable-poison-system-directories-- Enable-symvers=gnu--enable-long-long--enable-threads--enable-languages=c,c++--enable-shared--enable-lto-- Enable-__cxa_atexit--with-gnu-as--with-gnu-ld--enable-__cxa_atexit  --with-gmp=/home/charles/code/build_ Toolchain/toolchain--with-mpfr=/home/charles/code/build_toolchain/toolchain--with-ppl=/home/charles/code/build _toolchain/toolchain--with-cloog=/home/charles/code/build_toolchain/toolchain make all make
install

The resulting tool chain is as follows:

$./bin/arm-linux-gnueabi-gcc-v Using Built-in specs. COLLECT_GCC=./BIN/ARM-LINUX-GNUEABI-GCC collect_lto_wrapper=/home/charles/code/build_toolchain/toolchain/ Libexec/gcc/arm-linux-gnueabi/4.8.2/lto-wrapper Target:arm-linux-gnueabi configured with:. /.. /src/gcc-4.8.2/configure--build=i686-pc-linux-gnu--target=arm-linux-gnueabi--prefix=/home/charles/code/build_ Toolchain/toolchain--with-sysroot=/home/charles/code/build_toolchain/toolchain/arm-linux-gnueabi/sysroot-- Disable-libmudflap--DISABLE-LIBSSP--disable-nls--disable-libstdcxx-pch--with-interwork--with-mode=arm-- With-fpu=vfpv3--with-arch=armv7-a--WITH-FLOAT=SOFTFP--enable-libgomp--enable-poison-system-directories-- Enable-symvers=gnu--enable-long-long--enable-threads--enable-languages=c,c++--enable-shared--enable-lto-- Enable-__cxa_atexit--with-gnu-as--with-gnu-ld--enable-__cxa_atexit--with-gmp=/home/charles/code/build_ Toolchain/toolchain--with-mpfr=/home/charles/code/build_toolchain/toolchain--with-ppl=/Home/charles/code/build_toolchain/toolchain--with-cloog=/home/charles/code/build_toolchain/toolchain Thread 
 Model:posix gcc version 4.8.2 (GCC)

P. S.

1) at the beginning, with the GCC version is 4.9.2, in the 4th step, there is a similar "-meabi=5 not found" error, never found a solution, and finally had to switch to 4.8.2 version.

2 these several gmp-6.0.0 mpc-1.0.2 mpfr-3.1.2 ppl-1.1 cloog-0.18.1 module's dynamic library, only uses

Export Ld_library_path=/home/charles/code/build_toolchain/toolchain/lib

To use, or use the system.
