Running QMake and Make on different systems

[ChrisW67]

No, the easiest thing is the normal situation, where you build the program on one machine and deploy the result to another machine. You already have a machine with a working Qt environment that is binary compatible with the target (or you could not copy libraries across). Build there and deploy.

Hey Chris, thank you for the reply.

The normal situation is what I've done and desperately want to continue to do. The problem is in a number of core OS libraries that because of some oversight are old on the target machine and newer on our development machines. Code compiled against these non-Qt libraries blows up when dynamically linking against the older libraries on the target machine. That's why I'm trying to compile on the target machine - so that I link against those libraries. The target is binary compatible...I just can't install Qt on it because of process limitations, not technical limitations.

So I was able to resolve this. I took the makefile generated by qmake and pulled out all the gcc instructions and related declarations, putting them into their own makefile, including a make clean section. I then ran the full build, then ran the clean target of the gcc only makefile, leaving all moc files in place. I then transferred everything to my target system and ran the gcc only makefile. Worked like a charm.

Did you explore deploying private versions of the system libraries along with your application?
