6 #@ This script builds the (trusted) cross toolchain for arm.
7 #@ It must be run from the native_client/ directory.
9 #@ The toolchain consists primarily of a jail with arm header and libraries.
10 #@ It also provides additional tools such as QEMU.
11 #@ It does NOT provide the actual cross compiler anymore.
12 #@ The cross compiler is now comming straight from a debian package.
13 #@ So there is a one-time step required for all machines using this TC.
14 #@ Which is especially true for build-bots:
16 #@ tools/trusted_cross_toolchains/trusted-toolchain-creator.armel.precise.sh InstallCrossArmBasePackages
19 #@ Generally this script is invoked as:
20 #@ tools/trusted_cross_toolchains/trusted-toolchain-creator.armel.precise.sh <mode> <args>*
21 #@ Available modes are shown below.
23 #@ This Toolchain was tested with Ubuntu Precise
26 #@ compile: arm-linux-gnueabi-gcc -march=armv7-a -isystem ${JAIL}/usr/include
27 #@ link: arm-linux-gnueabi-gcc -L${JAIL}/usr/lib -L${JAIL}/usr/lib/arm-linux-gnueabi
