If you are also working with Nuttx<\/a>, you will love the “sim” configuration. It will allow running a minimal version of Nuttx as a regular program on a linux machine (assuming 86x_64).<\/p>\n

Before getting the sources and building anything you will need the 32-bit version of the GCC and the following libraries that can be installed like this:<\/p>\n

sudo apt-get install -y gcc-multilib libc6-dev-i386 lib32z1-dev<\/code><\/p>\n

After installing there is a final thing you need to fix on your own (see this launchpad ticket<\/a>)<\/p>\n

sudo ln -s \/usr\/include\/x86_64-linux-gnu\/zconf.h \/usr\/include<\/code><\/p>\n

Now get the Nuttx sources using git like this:<\/p>\n

git clone http:\/\/git.code.sf.net\/p\/nuttx\/git nuttx.git<\/code><\/p>\n

First thing after getting the sources is to run the configure script (a bit different from the well known .\/configure) to setup the build directory for the target hardware. In our case the target will be the native machine for which the “sim” configuration has been created (see nuttx\/configs\/sim).<\/p>\n

To configure the build setup for target “sim” with “nsh” as the application to run on start, run:<\/p>\n

cd nuttx.git\/nuttx\/tools
\n.\/configure.sh sim\/nsh
\ncd ..
\n<\/code><\/p>\n

Last step before building is the configure the image. This is done by calling<\/p>\n

make menuconfig<\/code><\/p>\n

There is at least one setting that needs to be enabled:<\/p>\n

– System Type —> [*] Build 32-bit simulation on 64-bit machine<\/p>\n

You are now ready to build the image<\/p>\n

make<\/code><\/p>\n

If there was no problem during the build you will find a “nuttx” file in the same directory. Just run it and you will see the NSH prompt.<\/p>\n
