[linux-audio-dev] producing a self-contained executable

Hi, I'm asking for a bit of help from someone having experience with the 'dirtier' side of Linux programming. :) My problem is that I need to present a single executable of my software that will run on as many systems as possible, without trouble caused by non-matching dynamic library versions. The software is a specialized medical application for hearing therapy of autist persons, to be distributed among a small (but heterogenous) client base. The current state is this: I compile the program, it runs on my system, but it generates relocation errors and the like if I copy the executable to another system with a different libc (or other library) version. This is what I would expect anyway, so no surprise at all. My first thought was that I should try to produce a statically compiled executable that contains each and every library it depends on, so it barely needs any pre-defined resources on the target system. Executable size and startup time is not an issue here, it just needs to run everywhere. Producing different executables for different machines is not an option. Changing these conditions is beyond my authority. I've run into difficulties trying to compile a statically linked version due to problems with GTK, which apparently doesn't allow me to statically link to it. I also don't really know how to get at statically linking libc (however I didn't try very hard anyway, since I already got stuck with GTK). The app uses GTK, lots of audio file format libraries, ALSA, JACK and of course libc. Any help (including pointers to howto-s about statically linking) would be very welcome. Tom
