I was recently tasked with performing a feasibility study based around switching from using DOS to Linux for use as an OS to run our industrial control software (developed internally). In a nutshell I have been restricted to using Ubuntu 8.04 (with a vendor supplied kernel upgrade providing drivers for the hardware on the board). As this is no longer supported I am unable to update or install software meaning that I am stuck using gcc version 4.2. I want to be able to use C++ and preferably boost libraries but currently this seems like I will not be able to do so.
Basically I am asking how do companies/professionals go about using Linux as a development environment? Is what I described above a common occurrence? Do you simply pick a version and a compiler and stick with it throughout the product lifetime to ensure that the development environment doesn’t change too much or can you freely upgrade the kernel, compiler etc. as you go along? Is it common to be constrained by what a particular vendor can provide. Would anyone be prepared to give their opinion as to whether ubuntu 8.04 is a suitable choice of OS for development of industrial control software?
I am not a linux expert at all, but my research and experimentation so far is leading me to conclusion that I should abandon the linux approach and use DOS. Our company has no linux knowledge and is very small and for personal career reasons I have no interest in learning redundant technology like DOS.
I realise this is not exactly a yes/no type question but any responses will be gratefully received.
GCC 4.2 has no C++11 support but the C++03 support should be good and you should be able to find a version of Boost that can deal with that quite easily.
Ultimately, Linux has many upsides you won’t find in DOS- for example, no segmentation, virtual memory, and such things that will make it easier and faster to develop software, not to mention additional libraries you might need, as absolutely nobody whatsoever will support DOS today.
