I purchased a Human Machine Interface (Exor Esmart04). Running on Linux 3.10.12, however this Linux is stripped down and does not have a C compiler. Another problem is the disk space:

I've tried to install GCC on it but I do not have enough disk space for this, does anyone have other solutions or other C compilers which require less disk space?
