Description jacky lau 2013-10-23 10:46:17 UTC

I'm using buildroot 2013.08.1 with linaro toolchain 13.06 (gcc-linaro-arm-linux-gnueabihf-4.8-2013.06_linux.tar.xz) to build image with directfb-examples package. When build directfb-examples package, building failed, gcc can't find librt and libdl. Full error message is:

Comment 1 Thomas Petazzoni 2013-11-14 00:02:30 UTC

You're right, the support for Linaro toolchains was broken in 2013.08.1. This problem has been fixed in 2013.11-rc1, by the commits:

11ec38b6950cf3337b52fb97f27c2fd7c776c5c2 toolchain-external: fix Linaro ARM toolchain support
b3e3d5fc28b26291d48adad96e92e27c86183673 toolchain-external: add missing symlink for Linaro toolchains

Can you retry with 2013.11-rc1 ?
