h1. How to get cross CIF for building LiteOS

Instructions are for Ubuntu 18.04.

Install prerequisites:

<pre>

$ sudo apt-get install autoconf automake libtool libexpat1-dev libncurses5-dev bison flex patch texinfo build-essential gawk gperf help2man libtool-bin

</pre>

Install CIF as usual. Below it is assumed that CIF sources and build files are within directory _<notextile>~/cif</notextile>_.

Download the ZIP archive from https://github.com/stephanosio/crosstool-ng/tree/newlib_nano_variant to the home directory. At the moment of writing this document the corresponding pull request was not accepted yet. Extract the ZIP archive. After that go to directory _<notextile>~/crosstool-ng-newlib_nano_variant</notextile>_ and execute the following commands:

<pre>

$ ./bootstrap

$ ./configure --enable-local

$ make

</pre>

h2. Build cross CIF

<pre>

$ mkdir ~/cif/build/cross

</pre>

Download file _.config_ attached to this page into _<notextile>~/cif/build/cross</notextile>_. Replace username _novikov_ with your one if necessary within _<notextile>~/cif/build/cross/.config</notextile>_.

<pre>

$ ~/crosstool-ng-newlib_nano_variant/ct-ng build

</pre>

h2. Get and build LiteOS

<pre>

$ git clone https://github.com/LiteOS/LiteOS.git

$ cd ~/LiteOS/targets/Cloud_STM32F429IGTx_FIRE/GCC

</pre>

Perhaps you need to replace username _novikov_ with your one.

<pre>

$ export PATH=$PATH:/home/novikov/x-tools/arm-unknown-eabihf/bin

$ make

</pre>
