Yip, it's all as documented. We use a EC2 cloud instance to build. The problem is we need to patch the LSB headers and tools to wrok around some issues in the other tools configurery. The result is still LSB compatible. contrib/linaro/build.mk does this automatically by calling contrib/linaro/lsb/make-lsb.sh and then putting the result in the path. Short story: what you did is right. -- Michael _______________________________________________ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
