- Subject: -fPIC and shared object
Hello,
I am using linux and I would like to understand the role of -fPIC. I
understand that it generate code where function address can be
calculated indirectly after relocation of the .so in applications
using it. My questions are :
- Is it required to compile with -fPIC every object file packed in a
dynamic shared object ?
- Is is possible to integrate a static library in a .so safely
(assuming the static library is not compiled using -fPIC)
- Is the answer to the previous question the same if the library is
used only within the boundary of the .so (hidden to the rest of the
application) ?
Thanks
