Hi!
Here's an example on how I use Dan Kegel's crosstool.sh script:
-----------------------------------------------------------
#!/bin/sh
PREFIX=/home/jbglaw/cross_jb/install \
BUILD_DIR=xx_build \
SRC_DIR=. \
BINUTILS_DIR=binutils-2.15.91 \
GCC_DIR=gcc-HEAD-20040509 \
GLIBC_DIR=glibc-2.3.2 \
LINUX_DIR=linux-2.6.x \
TARGET=alpha-linux \
TARGET_CFLAGS="-O -g" \
BUILD=`/usr/share/misc/config.guess` \
USE_SYSROOT=yes \
PARALLELMFLAGS="-j2" \
KERNEL_CONFIG=config-alpha ./crosstool.sh
-----------------------------------------------------------
PREFIX is where all your crosscompiler tools will be
installed into
BUILD_DIR is where some subdirs will be created to build all
the parts. You need some MBs free there:)
SRC_DIR This is where all the source sub-directories
(GCC_DIR, GLIBC_DIR, LINUX_DIR, BINUTILS_DIR) are in
GCC_DIR, GLIBC_DIR, LINUX_DIR, BINUTILS_DIR
Subdirs within SRC_DIR that contain the actual sources
TARGET Guess it:)
TARGET_CFLAGS CFLAGS used to for the toolchain to be created. "-O -g"
to have them optimized, as well as keep debug infos (in
case the compilers crash, you may want to help toolchain
people to debug the problem).
USE_SYSROOT Internal flag, which changes the destination directory
for some target-relevant files. I admit I haven't yet
understood that throughoutly:)
PARALLELMFLAGS Have a SMP machine?
KERNEL_CONFIG A ./linux/.config file for the kernel in LINUX_DIR. Used
to get proper kernel header files.
BUILD This machine's GNU quadrupel. Call config.guess to get
it; if you don't supply it, crosstool.sh will try to
call ./config.guess, which doesn't exist if you copy
crosstool.sh out of Dan Kegel's distribution:)
MfG, JBG
