Portability of binaries between various linux distro's
Will be developing a daemon for Linux systems which will unfortunatley be proprietary. I would love to make it open source, but alas my company and I do not agree on this matter. This brings me to my question. How portable will a binary version of the application be between various linux distro's and installations? Also, what could I do to improve/ensure this portability. As I am rather new to Linux development I have no idea as to what hurdles lay ahead in such an endevour.
Thanks for any assistance.
Portability depends on the language you use, the libraries you link to, the packaging system you use, and any number of other things. The only way I can think of to make something truly portable (meaning no recompilation at all) is to do it in Java.
Barring that, make sure your code is ANSI standard, that you link only to libraries that are very common and therefore likely to already be installed on your target machines, and insist on manual compilation (or a generic shell script) rather than any particular packaging scheme to install it.Registered Linux user #270181

Thanks for the help, but unfortunately Java poses a bit of a problem. I will be needing access to the systems hardware for various tasks, such as obtaining the MAC address. This is, to the best of my understanding, not possible with Java.

Of course, speed may be a concern for some apps, which makes Java an issue.
Typically most apps can be compiled only being concerned about the version of gcc you're using. If you anticipate people running older systems, I'd consider running a 2.9x version from RH7.3, although of course this is becoming less and less relevant with each passing year, to say nothing of the fact that this compiler had major issues and your code may not compile trivially. After that, if you compile, say, a version with gcc3.2 and gcc3.4, that would cover a pretty wide range of platforms. TM is right in that there could well be lots of other issues that enter into this, but for most apps IMHO this covers an awful lot of endusers. We run a very sophisticated app here that compiles along those lines and it's run under numerous distros(even those not featuring those specific versions of gcc) without troubles.
You can do anything in Java that you can do in C, just not as fast.
How is this possible? Through the Java Native Interface.
