+# trimui toolchain Docker image
+
+## Installation
+
+With Docker installed and running, `make shell` builds the toolchain and drops into a shell inside the container. The container's `~/workspace` is bound to `./workspace` by default. The toolchain is located at `/opt/trimui-toolchain` inside the container, libraries are in `/opt/trimui-toolchain/arm-buildroot-linux-gnueabi/sysroot/usr/lib/`.
+
+After building the first time, unless a dependency of the image has changed, `make shell` will skip building and drop into the shell.
+
+## Workflow:
+
+- On your host machine, clone repositories into `./workspace` and make changes as usual.
+- In the container shell, find the repository in `~/workspace` and build as usual.

+-Date: Tue, 23 Jun 2015 13:54:42 -0400
+-Subject: libpng: don't append prefix to symbol names in version script
+-
+-Even if Blackfin GNU toolchain add prefix '_' to all symbols,
+-symbol prefix is not accepted in the link flag --version-script.
+-Don't append prefix in the symbols in the version script file.
+-
+-Original patch by: Sonic Zhang <sonic.zhang@analog.com>

+-Rebase to apply cleanly.
