maya does not update recompilled plugin under linux

[Michał Frątczak]

Hi Group,

I am building a very minimal plugin under centos7 and noticed that maya stopped updating  .so file between compilations.

My loop looks like this:

    1. unload plugin in maya

    2. recompile/link

    3. load plugin in maya

    4. test...

It looks like maya keeps some kind of cache and I need to restart it to see changes in my .so file.

I 'think' (but not 100% sure) this started when I switched from static openEXR to dynamic linking and also added openVDB.so to link...

Any ideas what's wrong? Having to restart maya each time kill my productivity :/

thanks

What happens if you copy the `.so` file to a different path, and load that?​

The problem persists...

I tried both renaming file and cleaning build dir + rebuilding into new filename.so

In any case I need to restart maya to see effects. Funny...

Are you saying that it used to work, and now with either a different version of Maya, or a different version of Linux, it no longer works as you expect? 

In general, I would expect mixed results of unloading and reloading an so after making changes. If it worked before, and the behaviour has changed, then something could have changed in the way Maya is calling dlopen (http://man7.org/linux/man-pages/man3/dlopen.3.html). 

thanks

No, maya and its environment is exactly the same. It happened today, probably when I started linking my plugin dynamically against openEXR and openVDB .so files (before I used just EXR static .a libs).

Tomorrow I'll try to go back to static linking and check if that makes a difference.
