compile cross-compiler gcc-3.4.3 wth glibc-2.3.4 for ARM(920, v4) platform mini howto Author: Andylin (andylin@wellsyn.com) 1. Require files Compile cross-compiler need four components -- binutils, gcc, glibc, kernel source (1) binutils -- binary utility current latest version -- 2.14 file name: binutils-2.14.tar.gz where to get: (2) gcc -- GNU compiler collection <1> gcc-core version, which only include c language support. It is be used in first stage gcc compile. current latest version -- 3.4.3 file name: gcc-core-3.4.3.tar.bz2 where to get: ftp://ftp.gnu.org/gnu/gcc/gcc-3.4.3/gcc-core-3.4.3.tar.bz2 <2> normal gcc version, which support multi-language. It is be used in final stage gcc compile. current latest version -- 3.4.3 file name: gcc-3.4.3.tar.bz2 where to get: ftp://ftp.gnu.org/gnu/gcc/gcc-3.4.3/gcc-3.4.3.tar.bz2 (3) glibc -- GNU library collection <1> gcc library current latest version -- 2.3.4 file name: glibc-2.3.4.tar.gz where to get: <2> gcc library add on for glibc current latest version -- 2.3.4 file name: glibc-linuxthreads-2.3.4.tar.bz2 (4) Kernel source <1> Linux kernel source -- appropriate kernel version for compipling cross-compiler we using. version -- 2.4.26 file name: linux-2.4.26.tar.bz2 where to get: <2> Linux kernel source patch for ARM version -- 2.4.26-vrs1 file name: patch-2.4.26-vrs1.bz2 where to get: ftp://ftp.arm.linux.org.uk/pub/armlinux/source/kernel-patches/v2.4/patch-2.4.26-vrs1.bz2 (5) Other utility <1> Install "info2man" package which is include pod2man utility to produce manunal page. ======================================================================================================= 2. Require directory We need three directory of types. (1) tarball source directory -- storage tarball source from GNU website (2) extra source directory -- storage had de-compressed tarball source (3) building work directory -- these directories are working directory when we compile toolchain ======================================================================================================= 3. Require environment variable Because we compile cross-compiler for ARM platform on x86 machine, we must know machine name for variable platform. Note: the format of a GNU target specification is CPU-PLATFORM-OS x86/i386 target machine's name : i686-pc-linux-gnu/i686-host_pc-linux-gnu arm platform target machine's name : arm-linux We must decide "instalation" directory for install our compiled finish toolchain. For example: we install my toolchain to "/usr/local/mytoolchain". therefore, we define and export some environment variable for convenience later. export TARGET=arm-linux export PREFIX=/usr/local/mytoolchain export TARGET_PREFIX=$PREFIX/$TARGET export PATH=$PATH:$TARGET/bin note: If you had install previous version of arm-linux toolchain, you must remove search patch for it from PATH environment variable first. ======================================================================================================= 4. De-compress linux kernel source, patch kernel source and configure kernel source # tar -jxvf linux-2.4.26.tar.bz2 # bzip2 -cd patch-2.4.26-vrs1.bz2|(cd linux-2.4.26;patch -p1 -s -E) # cd linux-2.4.26 # make ARCH=arm CROSS_COMPILE=arm-linux- menuconfig (And then do not modify any thing, Save and exit.) # make dep ====================================================================================================== 5. Copy kernel header file to "installation" directory # mkdir -p $TARGET_PREFIX/include # cd linux-2.4.26/include # cp -a linux $TARGET_PREFIX/include # cp -a asm-arm $TARGET_PREFIX/include/asm # cp -a asm-generic $TARGET_PREFIX/include # cd $TARGET_PREFIX # ln -s include sys-include ====================================================================================================== 6. De-compress other tarball source <1> De-compress gcc-core # tar -jxvf gcc-core-3.4.3.tar.bz2 # mv gcc-3.4.3 gcc-core-3.4.3 <2> De-compress gcc # tar -jxvf gcc-3.4.3.tar.bz2 <3> De-compress glibc and linuxthreads package # tar -zxvf glibc-2.3.4.tar.gz # cd glibc-2.3.4 # tar -jxvf ../tar_source/glibc-linuxthreads-2.3.4.tar.bz2 <4> De-compress binutls # tar -zxvf binutils-2.14.tar.gz ====================================================================================================== 7. Patch tarball source <1> Pach glibc source Problem : "BUS_ISA" undeclared Solution: patch ioperm.c File location: glibc-2.3.4/sysdeps/unix/sysv/linux/arm/ioperm.c From: static int iobase_name[] = { CTL_BUS, BUS_ISA, BUS_ISA_PORT_BASE }; static int ioshift_name[] = { CTL_BUS, BUS_ISA, BUS_ISA_PORT_SHIFT }; To: static int iobase_name[] = { CTL_BUS, CTL_BUS_ISA, BUS_ISA_PORT_BASE }; static int ioshift_name[] = { CTL_BUS, CTL_BUS_ISA, BUS_ISA_PORT_SHIFT }; <2> Patch glibc source Problem : ld: cannot find -lgcc_eh Descript: gcc_eh library is not found.
