Dear all,
I’m trying to build a library with a code composed of several classes, and I encounter a problem. I can reproduce the problem for each class taken individually. The library seems to be built correctly :

All my code works fine without generating a library, and you can be sure of that by switching off the library in the Makefile with :
DOLIBRARY = noI’m using root v5.32.00 with a macbook pro 13’ on mac OS 10.7.3.
Thanks for your help!
