cross toolchain for building the beagle bone black and development

I needed to build a “newer” version of the Linux kernel for my beagle bone black since the kernel that came with board has this weird USB power issue ( uname : 3.8.13 - bone47).

My development environment is a virtual Box running Debian.(3.16.0-4-amd64)

I followed the instructions to build the Beagle bone kernel and image from the following website. (Thanks Robert Nelson). This worked great!
https://eewiki.net/display/linuxonarm/BeagleBone+Black

As part of those instructions, the cross compiler toolchain I installed was Linaro GCC 5.3-2016.02. The build_kernel.sh script actually (re)downloads this exact toolchain and uses it to build the kernel.

Now I have started to write code for my beagle bone application. I require to use Qt. I was able to the build the Qt library statically using the above linaro compiler. But when I try to link my application code against the build Qt library I get missing library link errors for libicuio, libicui18n, libicuuc, libicudata.

  1. How do I get the ICU libraries for the linaro compiler?
  2. I could use the debain multi-arch to apt-get the cross-compiler toolchain and icu stuff…but then I need to get the build_kernel.sh script to point to this compiler. Has anyone done this?

Thanks!

"it's" best to use your system compiler for qt libraries..

in the system.sh file in the kernel build script, just set CC=...
