-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
Hello,
I'm trying to build a toolchain for Freescale i.MX31 ADS I'm woking on. I have a working toolchain that is given by Freescale, but I want to be able to build it myself for future usage.
I've found a crosstool "config" file in the RPM toolchain given by Freescale which looks like that:
[arm-none-linux-gnueabi]> pwd /opt/freescale/usr/local/gcc-4.1.1-glibc-2.4-nptl-2/arm-none-linux-gnueabi [valentin@lsa1pc7][13:55:44] [arm-none-linux-gnueabi]> cat arm-none-linux-gnueabi.crosstoolconfig.txt AR= BINUTILS_DIR=binutils-2.16.92 BINUTILS_EXTRA_CONFIG= BUILD=i686-pc-linux-gnu BUILD_DIR=/usr/src/redhat/BUILD/crosstool/build/arm-none-linux-gnueabi/gcc-4.1.1-glibc-2.4-nptl-2 CC= DEJAGNU= EXTRA_TARGET_CFLAGS=-mabi=aapcs-linux GCC_BUILD= GCC_CORE_DIR=gcc-4.1.1 GCC_DIR=gcc-4.1.1 GCC_EXTRA_CONFIG=--disable-libunwind-exceptions GCC_HOST= GCC_LANGUAGES=c,c++ GDB_DIR= GLIBC_ADDON_OPTIONS==nptl,../glibc-2.4/ports, GLIBC_DIR=glibc-2.4 GLIBC_EXTRA_CC_ARGS= GLIBC_EXTRA_CONFIG=--with-tls --with-__thread --enable-kernel=2.6.4 --with-abi=aapcs-linux GLIBC_EXTRA_ENV= JUST_DOWNLOAD= KERNELCONFIG=/usr/src/redhat/BUILD/crosstool/crosstool-0.42_fsl/armeabi.config LINUX_DIR=linux-2.6.17.1 LINUX_SANITIZED_HEADER_DIR= NO_DOWNLOAD= PREFIX=/opt/freescale/usr/local/gcc-4.1.1-glibc-2.4-nptl-2/arm-none-linux-gnueabi PTXDIST_DIR= SHARED_MODE=--enable-shared SRC_DIR=/usr/src/redhat/BUILD/crosstool/source TARBALLS_DIR=/opt/freescale/pkgs TARGET=arm-none-linux-gnueabi TARGET_CFLAGS=-O TOP_DIR=/usr/src/redhat/BUIL
First question: what is this crosstool-0.42_fsl ? What does the fsl stand for ? Anyone knows that ?
Now, I have done my own file to use with my local crosstool version:
[valentin@lsa1pc7][13:50:31] [crosstool-0.42]> cat imx31.sh #!/bin/sh set -ex TARBALLS_DIR=$HOME/downloads RESULT_TOP=/opt/crosstool export TARBALLS_DIR RESULT_TOP
# Really, you should do the mkdir before running this, # and chown /opt/crosstool to yourself so you don't need to run as root. mkdir -p $RESULT_TOP
BINUTILS_DIR=binutils-2.16.92 export BINUTILS_DIR
BUILD=i686-pc-linux-gnu export BUILD BUILD_DIR=$HOME/EPFL/diplome_ASL/toolchain/crosstool-0.42/build/arm-none-linux-gnueabi/gcc-4.1.1-glibc-2.4-nptl-2 export BUILD_DIR

TARGET=arm-none-linux-gnueabi export TARGET TARGET_CFLAGS=-O export TARGET_CFLAGS
TOP_DIR=$HOME/EPFL/diplome_ASL/toolchain/crosstool-0.42 export TOP_DIR
sh all.sh --notest
But when I run this script, I finish in a state where I have an infinite loop on the glibc configure script:
...
+ libc_cv_ppc_machine=yes + CC=gcc + /home/valentin/downloads/glibc-2.4/configure --prefix=/usr --build=i686-pc-linux-gnu --host=arm-none-linux-gnueabi --without-cvs --disable-sanity-checks --with-headers=/opt/crosstool/gcc-4.1.1-glibc-2.4-nptl-2/arm-none-linux-gnueabi/arm-none-linux-gnueabi/include --enable-hacker-mode checking build system type... i686-pc-linux-gnu checking host system type... arm-none-linux-gnueabi configure: running configure fragment for add-on glibc-2.4 checking build system type...

(cached) i686-pc-linux-gnu checking host system type... (cached) arm-none-linux-gnueabi configure: running configure fragment for add-on glibc-2.4
...
This is from what I've seen caused by the GLIBC_ADDON_OPTIONS=nptl,../glibc-2.4/ports, that I've changed and event commented out, but it doesn't change anything . Anyone has an idea ?
Now seeing that Mike Frysinger is browsing this list and I'm using gentoo, I've thought about using crossdev to build this toolchain. Here is what I've launched (still waiting, my laptop is slow):
lsa1pc7 ~ # crossdev -t arm-none-linux-gnueabi -------------------------------------------------------------------------------- * Host Portage ARCH: x86 * Target Portage ARCH: arm * Target System: arm-none-linux-gnueabi * Stage: 4 (C/C++ compiler)
* binutils: binutils-[latest] * gcc: gcc-[latest] * headers: linux-headers-[latest] * libc: glibc-[latest]
* PORTDIR_OVERLAY: /usr/local/portage * PORT_LOGDIR: /var/log/portage * PKGDIR: /usr/portage/packages/cross/arm-none-linux-gnueabi * PORTAGE_TMPDIR: /var/tmp/cross/arm-none-linux-gnueabi
What should I do to use crossdev to be with a gcc whose options look like the one given by Freescale which looks like this ?
[crosstool-0.42]> /opt/freescale/usr/local/gcc-4.1.1-glibc-2.4-nptl-2/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi-gcc -v Using built-in specs.

Thank you for helping me, regards,
